MeSH:	ORAL SURGICAL PROCEDURES MAXILLARY SINUS
Abstract:	In the posterior maxilla the residual bone volume very often is not sufficient for implant placement and consecutive implant supported prosthetic treatment. Thus the technique of sinus grafting, utilizing the lateral window techique, has to be applied. The objective of this retrospective study was to evaluate frequency and type of postoperative complications and their influence upon treatment outcome.In the last ten years 397 sinus sites have been augmented consecutively. 41 (10.3%) for single tooth replacement. 247 (62.2%) for partial edentulous sites and 109 (27.5%) treating maxillary edentulous patients. 869 implants have been placed. All patients are in an least once-a-year recall routine. Data management and check-ups of patinets was achived by an independent researcher not involved in patient treatment.In 250 sites (59.7%), with bone height of less than 4 mm, two stage procedure was chosen. 147 sites (40.3%) showed sufficient bone volume for primary implant stability. 80.9% of the sites were augmented with special xenografts (Bio-Oss), 4.3% with special autografts and 14.8% with combinations of brafting materials. 62 complications involving 77 implants were subsumized in 6 different groups and 3 degrees of severity. There were 31 sites with implant failures. 4 buccal implants exposures. 15 dehiscences of oral mucosa with and without loss of augmentation material or membrane/implant exposure. 3 acute po. Infections. 9 considerable reductions of augmentation volume and 2 cases of acute late sinusitis with empyema. This means a complication rate of 15.6%. In 34 (8.6%) cases the treatment plan was not affected. 20 (5%) made necessary modification of the treatment plan and in just 8 cases (2% of all) implant supported prostheses could not be achived.Despite a raletively high incidence of postoperative complications the treatment objective of implant-supported rehabilitation of the posterior maxilla could be achived in 97.2%, including changes of the treatment plan in 8.2%. Within the limits of a retrospective study the present investigation showed implants placed in combination with sinus augmentation functioned successfully during an observation period of 10 years.

Type of Article:	congress abstract
MeSH:	DENTAL IMPLANTATION + methods
Abstract:	A decisive feature of the two-piece implant system of today is a mechanically strong, reliable implant abutment interface. This demand can be optimally achived by a precisely machined, tapered cone abutment (Morse taper) connection. This tapered abutment connection provides high resistance to bending and rotational torque during clinical function which significantly reduces the possibilities of screw fracture of loosening. Additionally, tapered abutement connection causes a platform switched design at the coronal portion of the implant. It enables a thick layer of dense soft tissue to form around the neck of the abutment an dcover the remaining horizontal area of the platform. This thick tissue masks the colour of the titanium that is cervical to the fixed prosthesis and is responsible for normal tissue colour. This platform switched implant design also moves the site of the implant-abutment interface from the outer top margin to the center of the implant shoulder, enabling the establishment of a bilogical width that is perpendicular to the long axis of the implant. The height of the marginal osseous crest (crestal bone) is maintained at the coronal top of the implant shoulder- it plays a decisive role in the formation and long term maintenance of papillas. Additionally, the platform switched design facilitates the mounting of submucosal placed abutments, preventing imapction of soft tissue between the implant-abutment interface. Both the high strength and initial small diameter of the abutment make it possible to obtain: (1) excellent aesthetics and (2) suprastructures that are clinically very similar to tooth borne prostheses.

Type of Article:	congress abstract
MeSH:	DENTAL IMPLANTS, SINGLE-TOOTH
Abstract:	The aesthetic result in anterior areas, especially in the upper jaw, is one of the most difficult implantological questions. However there are many preimplantological parameters, which can be diagnosed before surgery, so that it is easily possible to get a predictable result. Some of them are the type of gingiva, horizontal and vertical bone quantity etc. Our clinical experience has demonstrated that implantation in younger people without augmentation, when necessary only for aesthetics and not for function, should no longer be tolerated.Our aim is to present different types of augmentation in hard (bone spreading, autologous and allogenic) and in soft tissue (FTG) and to show the predictable results with satisfied patients. Some system advantages allow us to insert low diameter implants with very good emergence profile and no problem with vestibular bone loss.A challenge in implantology is the predictable, long-term aesthetics result, replacing incisors and canines of the upper jaw. Besides multidisciplinary cooperation between oral surgeons, prosthodontists and dental technicians the results depends on the correct emergence profile of impant borne crowns. A wide diameter implant platform should be chosen in case of replacing upper central incisors or canines. However, an analysis of the literature, theoretical considerations regarding ovate shaped pontics of conventional bridges, and many cases, lead to the conclusion that the emergence profile is indipendent of the used implant diameter. The profile is exclusively defined by the shape of the implant borne crown.Therefore, small implant diameters can be used if there is less bone amount, preventing many advanced surgical procedures to improve the bone amount in the oral-vestibular dimension.

Title in English:	Are Our Patients in Favour of Implantoprosthetic Rehabilitation?
Title in Croatian:	Jesu li naši bolesnici skloni implantoprotetičkoj rehabilitaciji?
Type of Article:	congress abstract
MeSH:	DENTAL IMPLANTATION
Abstract:	Based on 12-year experience we can answer affirmatively. Another question is whether patients, in spite of the daily promotions in the media by some dental surgeries, are sufficiently familiarised with the realistic possibilities of such rehabilitation. If we compare data on the number of examined patients referred for construction of an implant with the number of those in whom implants had been constructed, it can be concluded that only 30% of the cases showed indication for such rehabilitation. As a number of our patients give up because of financial reasons, the duration of the procedure, or because of local and general contraindications, the aforementioned percentage is considerably smaller. In Europe today there are 253 different implantological systems on the market, and in German dental surgeries 250 000 implantations are performed each year, regardless of the fact that the public health insurance does not cover the costs of such treatment. Although we shall never be able to compare ourselves with such countries, we have to aspire to educate our students, dentists and specialists in order to enable them to define indications and participate in the various phases of such rehabilitation, and later in the maintenance of implants and prosthetic restorations. We must not give unrealistic promises to patients, and compromising solutions should be avoided, often in spite of the patient’s contrary insistence. The basis of success is in the planning and teamwork, in which the dental technician is also included. On the other hand, our patients are not sufficiently conscientious regarding the maintenance of oral cavity hygiene, and still less the habit of regular check-ups after implantoprosthetic rehabilitation.We will present several patients motivated for implantoprosthetic rehabilitation, in whom, because of different contraindications, implantation was not carried out, and the patients were supplied with classical prosthetic devices. We will also demonstrate that occasionally implantoprosthetic rehabilitation leads to good results in patients with worn out prosthetic devices and periodontopathy.

MeSH:	DENTAL IMPLANTS
Abstract:	Today, therapy of partial or complete edentulousness by dental implants plays an increasingly significant role in the oral rehabilitation of patients, and is expected in the future to further increase in accordance with the development of other medical fields. However, all ardent advocates of dental implants and implantological enthusiasts, must know how to control and direct their activity through the prism of physiological and pathophysiological events in each patient, regardless of whether he/she is entirely healthy or effected by some pathological disorder, having in view his/her general and oral health.Many medically compromised patients seek implantological therapy for the purpose of their oral rehabilitation. We are of the opinion that today guidelines for pre and post implantological therapy of such patients have still not been entirely clarified, and consequently are not completely clear to dental practitioners and oral surgeons. The purpose of our presentation is to give a critical assessment of opinions and literature to date, and to give clear and scientifically founded guidelines for implantological therapy in such patients.Current knowledge will be discussed on the influence of the most frequent systemic and local diseases, impairments and conditions on therapy by dental implants. They include disorders and changes in bone metabolism (osteomalacia, osteopenia, osteoporosis, osteoradionecrosis) and ageing of the patient - diabetes mellitus, xerostomia, conditions in the area of the jaw following irradiation, ectodermal dysplasia, cardiopulmonary disease, smoking, hypothyrosis, autoimmune diseases (sclerodermia, Chron’s disease), Parkinson’s disease and haematological diseases (anaemia, leukaemia, haemostasis disorders....) and conditions caused by various medications (corticosteroids, cytostatics, phenitoin, blockers of calcium canals....).Specific pathophysiological aspects of the influence of the aforementioned conditions on the process of osseointegration and their possible effect on dental implants, will be explained in detail for the purpose of their possible and more simple application in the daily practice of every clinician engaged in dental implantology. Accordingly, we will present our guidelines for pre and post surgical treatment of implanted, medically compromised patients.

MeSH:	DENTAL IMPLANTATION
Abstract:	One of the fundamental pre-conditions for successful therapy by osseo-integrating implants is good pre-surgical planning. The aim of this work is to present the possibilities of radiographic and prosthetic evaluation prior to surgical treatment in the case of partial edentulousness.in the distal part of the mandibula. Diagnostic wax-up is done on a model of the jaw. After which a pattern is made of vacuum thermoplastic foil. Metal pellets of known diameter are placed in the positions of the waxed-up teeth to enable radiographic evaluation of the possibility of implantation in the planned positions. Classical orthopantomography is performed on the basis of which a multi-layer tomogram is done with exact cross-sections of the mandibula in the positions of future implants. On the basis of radiographic findings the position and length of the implants are determined. The classical two-phase surgical protocol is described and surgical technique with intraoral pre-prosthetic patterns. Astratech microthread implants of conical profile are used to ensure that the implant diameter is as close as possible to the diameter of the future tooth. The length of an implant is determined in accordance with the cited radiographic analysis, so that the implant in position 35 is shorter in relation to implants 34 and 37, due to the anatomic position of the foramen mentale. During surgical positioning of implants, apart from the position which is defined by the pattern, in the vertical direction the implants are positioned in accordance with the biological width of the mucous membrane and finally with periodontal aesthetic requirements. The results show the success of the therapy following good planning and preparation. The advantage is shown of multi-layer tomography in planning and determining the anatomical-morphological characteristics of the lower jaw, which provides assurance in the choice of length and particularly the width of the implant. Pre-surgical planning is a procedure by which it is possible to foresee the position of an implant and aesthetics of future prosthetic work, and thus to facilitate the surgical intervention.

MeSH:	ORAL SURGICAL PROCEDURES MAXILLARY SINUS
Abstract:	In a great number of cases implantoprosthetic rehabilitation in the upper jaw is difficult, as extensive resorption of bone occurs as a consequence of pneumatisation of the maxillary sinus following the loss of teeth. The surgical technique of lifting the sinus floor consists of the elevation of the sinus floor cranially and reinforcement of the bone defect in order to create sufficient height and width of the alveolar ridge for implant insertion.Material used for reinforcement of the bone defect is a combination of autologous bone with heterologous bone, in this case non proteinised beefbone (Bio-Oss) in granules. The ratio of mixingautologous and heterologous bones 20 : 80 shows good clinical results. The choice of technique for sinus floor lifting is determined by the height of the alveolar ridge, i.e. sinus floor, If the height of the bone ridge is < 4 mm, we apply lateral approach into the sinus through the trepanation opening, with lifting of lateral bone lamella in the sinus and reinforcement of the bone defect and delayed implantation after 6-9 months.The height of the bone ridge > 4 mm determines the lateral approach into the sinus with reinforcement of the bone defect and simultaneous implantation. In both cases of lateral approach to the sinal cavity the bone defect is covered by bio-resorptive collagen membrane (Bio-Gide).In the case of bone ridge height > 6-7 mm, socalled osteotomy technique is applied with lifting of the floor of the sinus through the implant support and simultaneous implantation. This method is internal, as opposed to the others, which are external. Surgical methods for lifting the floor of the sinus achieve an enlarged jaw ridge in the upper jaw. Sufficiently long and wide implants inserted in such bone are capable of withstanding the powerful masticatory forces of this area and restoring functionality, and overcoming the phonetic and aesthetic defects caused by the loss of posterior teeth in the upper jaw.

MeSH:	DENTAL IMPLANTS
Abstract:	The first report on immediate placement of dental implants dates back to 1978. Since then, many studies have been published and some guidelines have been established. The advantages include reductions in the number of surgical interventions and in the treatment time required. Appropriate orientation of the implant is achived more easily, there is less bone resorption and better soft tissue aesthetics can be expected. On the other hand, incongruity between the shape of the implant body and the extraction socket and the presence infection may adversely affect clinical success. The goal of out study was to compare the success and survival rates of immediately palced implants to delayed and late implant placements.Review of all implants placed from 1998 to 2005 at the Clinical Department of Maxillofacial and Oral Surgery in Ljubljana was performed. Epidemiological characteristics were recorded and clinical success rates for immediate versus delayed/late groups were calculated and compared.421 implantation operations on 381 patients were performed and 911 dental implants were placed. Among them, 62 were immediate mplants. The general survival rate was 98.5%. Survival rate for the delayed/late palcements was 98.5% (836/849) and 98.4% (61/62) for the immediate group. There have been some differences regarding implant localisation and the use of osteoplastic procedures between the groups.Survival rate of immediately placed implants is similar to the late/delayed placed implants. Straightforward surgical technique with thorough debridement of the socket, use of guided bone regeneration procedures and systematic application of antibiotics outweights the increased risk infection and implant loss in immediate palcements. As soft tissue aesthetics are expected to be superior with immediate implants, this type of implantation should be encouraged with our patients.

Type of Article:	congress abstract
MeSH:	JAW CYSTS
Abstract:	Tricalcium phosphate - Ca3(PO)2 is a resorptive and bio-compatible calcium phosphate ceramic with the ratio of calcium and phosphate atoms very similar to natural osseous mineral. Thus in the tissue it behaves like its own bone transplant. On the market it appears in the form of granules of different size. It gradually becomes entirely resorbed during the conversion of bone and substitution with new osseous tissue. In oral surgery it is mainly applied for major bone defects which occur after cysts and tumours operations, and in dental implantology. It can serve as a carrier of osteoinductive supplements, such as morphogenetic protein, and maintain its activity. The best known representatives of this group are Ceros 82, Calciresorb, Sinthograft, Augmen, Ilmaplant, while more recent are Cerasorb, Bio-Resorb and Biovision, preparations on the basis of beta-tricalcic phosphate. The purpose of the paper is to show the dynamism of healing bone defects of the jaw, remaining after operations for cysts, tumours, or other pathological lesions, which are filled with granulate Bio Resorba, and to compare them with other wellknown methods of treatment. The procedure was carried out in hospitalised patients with their consent in the Clinical Department of Oral Surgery, University Hospital “Dubrava.” The bone defects were filled with the appropriate amount of granulates, 1 000 -2 000 μm in size. Healing results were subjectively evaluated by analysis of radiographs after 2, 4, and 6 months and compared with the healing of the same kind of cavities treated by other procedures. Out of 37 cases Bio-Resorb was applied in 10 cases (3 radicular cysts, 2 follicular cysts, 2 odontogenic keratocysts and three traumatic bone cavities/cysts), which resulted in bone cavities larger than 3 cm in diameter. In one case a female patient developed infection and rejection of the granules, and repeated inflammatory problems lasted for two months after the intervention. No other patient showed complications, and the renewal of bone structure was completed in the period from 4 to 6 months after the intervention. The presented examples and their comparison with the results obtained by methods of excochleation and decortication of the jaw, or excochleation and permanent post operational suction, favour the application of resorptive tricalcic phosphate, particularly in the treatment of large traumatic bone cavities. This method ensures faster establishment of the expected bone structure than other applied methods.

MeSH:	REHABILITATION DENTAL IMPLANTATION
Abstract:	Loss of intermaxillary relations due to wear or carious destruction of tooth crowns is an everyday problem in prosthetic therapy. As a rule it includes long-term oral rehabilitation with splints, and in situations with a maintained supportive segment fixed prosthetic therapy with inlays, onlays, crowns and bridges. In extreme situations contact between the maxillary and mandibular alveolar ridge can occur. A case is presented of implantoprosthetic rehabilitation in bilateral loss of intermaxillary space as a result of long-term carious destruction of teeth crowns, with maintained intermaxillary relation in the intercanine segment. In cooperation with a specialist in dental prosthetics, a plan of therapy was drawn up, based on the maintenance of existing intermaxillary relations. Therapy with a bite splint would have involved change in the intermaxillary angle, and was therefore abandoned because of the need to maintain the existing vertical dimensions of occlusion in the intercanine segment. Following conservative treatment of the remaining teeth, in the intercanine segment, intermaxillary relations were registered, OPG of the patient was digitalised and the height of the alveolar ridge measured by specially developed software (Dentist 1.1. Pelsys, Croatia). Measurement confirmed that reduction of the alveolar ridge by 7-9 mm in the area of the right first premolar up to the first molar, and 4-7 mm in the area of the left first premolar up to the first molar, would ensure sufficient space for a fixed prosthetic restoration, without endangering integrity and biomechanics of the lower jaw. Extraction of the remaining teeth roots was performed bilaterally in the mandible, and levelling of the alveolar ridge of the mandible. At the same time two implants each were implanted on place 34 (length 9.5 mm, diameter 3.5 mm), 36 (length 9.5 mm, diameter 4.5 mm), 44 (length 9.5 mm, diameter 4.5 mm) and 46 (length 9.5 mm, diameter 4.5 mm). After a period of osseointegration of 4 months a fixed prosthetic restoration was fabricated with which the patient’s habitual intermaxillary relation was retained.

Abstract:	Immediate placement of an implant in the fresh alveoli of an extracted tooth has many advantages compared to delayed implantation. In the first place the shortened period of implant prosthetic rehabilitation of approximately 6-8 months, which is the time necessary for the alveoli to fill with the newly formed bone, the smaller number of surgical interventions, prevention of bone resorption and better positioning of the implant. Histomorphometrical analyses on an experimental model have demonstrated that healing of the bone defect around the immediately placed implant in post-extraction alveoli is complete and that the possibility of osseointegration better than in the case of delayed implantation. The reason is the greater potential for healing fresh extractive alveoli. Schultes’s investigation showed that the percentage of osseointegrated surface 6 months after immedi-ate placement of implants was 80%, compared with delayed implantation where this percentage was somewhat less, 75%. An example is given of a female patient, aged 56 years, with distal partial edentulousness/edentia of the left side of the upper jaw. Complete implantoprosthetic rehabilitation was achieved by a combination of two different types of implants and the technique of immediate implantation of a conical, screw implant into the fresh alveoli of an extracted left upper canine. An example will also be given of immediate implantation with augmentation of the bone defect by autologous bone transplant in the case of loss of one tooth in the frontal region and an example of immediate implantation on the site of extracted lower canines, with anchors of the lower supporting prostheses.

MeSH:	JAW, EDENTULOUS + therapy DENTURE, PARTIAL, FIXED
Abstract:	One of the methods of implantoprosthetic therapy of complete edentia/edentulousness of the lower jaw is the fabrication of a fixed bridge on implants. Such therapy assumes the placement of 4 to 6 implants in the interforamen area and construction of bridges on the implants. Such bridges are usually fixed with screws, rarely cemented, and distal cantilever are the rule. The basic problem in screwed fixed superstructures is passivity. Because of the technological process of constructing metal superstructures, thermal changes are not unusual, which results in the occurrence of tension when fixing on the implant. Any tension is harmful and finally leads to mechanical complications of the superstructure. Another problem is distal cantilever. As a general rule the length of the cantilever amounts to 2X, in which X represents the vertical length (space) between the last and the penultimate implant. This means that cantilever can be longer, which is better spatial arrangement of the implants. Other less important problems with cantilevers are of a technical nature and can be avoided by correct shaping of the superstructure. The presentation gives an evaluation of the success of therapy with screwed fixed bridges in the lower edentulous jaws. The period of monitoring ranges from 3 to 5 years, with analysis of complications in the same time period. Mechanical and biological complications are separately analysed. The frequency and character of mechanical complications are analysed. The results of the research provide guidelines for safer and more successful clinical work with such types of prosthetic superstructures on implants.

MeSH:	DENTAL IMPLANTATION + adverse effects
Abstract:	With the ever increasing number of placed implants it is inevitable that the number of complications connected with such therapeutic procedure will also increase. One of the complications which is hardest to treat and which consequently can lead to loss of the implant, is bacterial caused periimplantitis. This case presentation describes the successful therapy of advanced periimplantitis. The male patient, aged 58 years, was referred to the periodontist because of problems in the oral cavity in the form of unpleasant breath and suppuration around the tooth and implant. During the periodontal examination it was observed that both implants on places 22 and 25 were affected by periimplantic mucositis and bleeding and suppuration occurred during probing. With regard to the implant in area 25 the problem of complete loss of keratinised gingiva was also present. On the basis of the clinical and X-ray findings, and positive microbial test for periodontopathogens, periimplantitis was diagnosed around both implants. Initial periodontological therapy was carried out in four visits. The patient received instructions on the maintenance of oral hygiene and antiseptic therapy was included, rinsing with chlorhexidine and application of chlorhexidine gel directly into the pockets around the implants. As after this therapy the suppuration did not stop antibiotic therapy was included, with rinsing of the pockets with iodine. After successful control of the infective process, further therapy involved a periodontological surgical operation in order to correct the loss of keratinised gingiva around implant 25 and to obtain new attachment. After lifting the flap the surface of the implant was cleaned with sterile cotton wool soaked in chlorhexidine, and from the palate a connective transplant was taken and placed on the bone and the exposed thread of the implant. Gengigel (hyaluronic acid) was placed over the transplant for better healing of the wound. Five months after the operation microbial analysis was repeated. Periodontal pathogens were no longer present and clinical measurements showed reduced probing depth, absence of bleeding and suppuration, and the occurrence of zones of keratinised gingiva of 2 mm around implant 25.

Abstract:	To examine the epidemiological characteristics and differences in the occurrence of caries among the examined urban and rural populations of different social status. Performed according to the recommendations of the World Health Organisation (WHO) on a sample of 190 examined subjects, aged 35-44 years. After completion of a questionnaire, oral examination and medical-statistical analysis of data the following results were obtained: a-1) In the table on dental morbidity of labourers the intensity of caries is expressed by KEP-index and mean KIP. In the male examinees KEP amounts to 14.26, while the total KEP is 585. In females KIP is 15.84 and total KEP 301. Calculated χ2 amount to 19.8019 while tabularly at the level of reliability of 0.05 and with two degrees of freedom, it amounts to 5.99. a-2) For office workers the total KEP for men and women is 397, and average KIP-index 14.50. Calculated χ2 amounts to 6.2254, while tabularly it is the same as a-1. a-3) For agricultural workers total KEP for men and women is 176, and average KIP-index 14.64. Calculated χ2 amounts to 1.0515, while tabularly it is the same as a-1. b) In the table of KIO, KIZ and KIP relations for all examinees KIP 98.80%, KIZ 48.17% and KIP 14.60%. c) In the table showing the relationship between the level of oral hygiene and the number of caries for all examinees, total K 134, KIP 1.82, total OHI-index 221.29 and OHI-index per person 2.22. d) Data on the number of caries and the level of oral hygiene correlate, i.e. when there is a higher number of caries in the mouth, oral hygiene is poorer. At the time of the examination oral hygiene was better in women.

MeSH:	DENTAL IMPLANTATION + methods COMPOSITE RESINS
Abstract:	Fibre reinforced composites (FRC) are a specific group of materials consisting of composites in which determined types of fibre are inserted. The fibres differ according to their chemical composition and method of construction. With regard to the chemical composition, polyethylene and glass fibres are most frequently used today in restorative and aesthetic dentistry (apart from these two types, carbon and kevlar fibre can be found). According to the method of construction the fibres can be parallel or plaited. Plaited fibres differ mutually with regard to the size and method of plaiting. In the last few years application of fibres in daily clinical work has become increasingly important. Their application has been found in almost all areas of the dental profession: periodontology, restorative dental medicine, traumatology, orthodontics, etc. The fibres can be constructed in two basic forms: impregnated and unimpregnated. Impregnated fibres are packed in a special way and already coated with the composite base, while in the case of unimpregnated fibres prior preparation is necessary before insertion in the composite material. The application of fibre reinforced composites has opened up new possibilities in the treatment of specific problems which can occur during implantological-prosthetic therapy. The purpose of the lecture is to show the possibilities of the application of fibre reinforced composites in different clinical cases and to describe possible errors during clinical construction.

Abstract:	The paper presents case presentations from own experience in which a specific implantological system was used. This system differs from other implantological systems. Among other things, it differs in that it has a resilient superconstruction in which a friction system is incorporated. The implant is a cylindrical shape and contains an anti-epithelial membrane which must be placed beneath the level of the bone in order to avoid ingrowing of the epithelium between the bone and the implant. In place of a thread this type of implant has 4 apices which together with the antiepithelial membrane act as primary fixation elements. The resilient superconstruction successfully imitates the periodontal ligament, which in a fixed prosthesis enables connection of the natural teeth with implants by applying resilience of around 20 μ, and in a mobile prosthesis imitation of resilience of the mucous membrane of around 80 μ, and in this way contributes in both cases to correct reduction of masticatory forces, which is the best protection of the implant. Each superconstruction has a friction cap which is fixed into the prosthetic restoration, and with its internal area lies conically on the primary part of the superconstruction, where frictional forces are created of 2200 g, enabling placement of the prosthetic device without cementing. The advantage of such fixing is the possibility of controlling the gingiva and implant beneath the prosthetic device. Thanks to the characteristics of these superconstructions the construction of prosthetic devices on implants is greatly simplified. Taking imprints on these superconstructions is identical to taking imprints on natural ground teeth. The features of this implantation system widen the possibilities for construction of fixed, combined and mobile prosthetic devices.

MeSH:	DENTAL IMPLANTATION JAW, EDENTULOUS + therapy
Abstract:	Complete loss of teeth means interruption of the physiological, mental and aesthetic harmony of the stomatognathic system. Attempts are made by prosthetic therapy to compensate for the functional inability by complete prostheses. Apart from the renewal of the ability to masticate, natural appearance and normal speech, the intention is to retain for as long as possible the tissue of the stomatognathic system. At the same time to create biological and mental preconditions for maximal acceptance of full prostheses. A full prosthesis is a restoration and does not enable optimal function of all components. Whether the patient will accept the prosthesis depends on the possibilities and desire to adapt to the new situation. Success of therapy with full prostheses depends on the shape, appearance and resorption of the alveolar ridge, muscular action and their influence on the mucus membrane, which is in direct connection with the full prosthesis. In therapy with full prostheses, a lower full prosthesis represents a particular problem, which is a challenge for every prosthodontist. Fabrication of a lower full prosthesis greatly depends on morphological characteristics, which arise in the lower jaw with the loss of teeth. The basis of successful fabrication of a lower full prosthesis, apart from correct use of clinical-technological methods, is knowledge of the anatomy of the lower jaw and surrounding structures, their relationship to the base of the lower full prosthesis and the prosthesis itself. In conclusion, each form of therapy has its advantages and disadvantages. The advantages of the implant borne restoration, are clearly increased retention and stability, contact with the mucous membrane is not primary, and the anticipated stimulation of the bone is periimplantary. The disadvantages are the feasibility with regard to the mental state of the patients, position ion the mucous membrane (control of base stability and essential underlaying) and the strength and efficacy of mastication (is comparatively reduced). Clinical advice. Never work with “unknown” patients. Get to know the patient first through diagnostic protocol, assess his/her cooperation, acquaint yourself with indications and general medical, intraoral, time restricted and mentally conditioned contraindications, in order to successfully carry out implantoprosthetic therapy.

Abstract:	In everyday dental practice the problem of prosthetic solution of total edentulousness in a more or less marked atrophic lower jaw, is a particularly difficult problem. Beside classical prior prosthetic procedures such problems can also be solved with the placement of dental implants. It is then essential to carefully plan the position of the implant, calculate height, width and density of the bone on the planned area, calculate anatomic and intermaxillary relations and plan the correct superstructure in order to ensure for the patient optimal retention and stabilisation of the prosthetic restoration. Such a restoration must functionally, aesthetically and phonetically satisfy the patient. Whether the condition of the lower edentulousness with implantoprosthetic rehabilitation is solved with a mobile prosthetic or fixed prosthetic superstructure depends on the possibilities of inserting a particular number of implants, the patient’s wish and also financial possibilities. The paper presents the case of a 58-year-old female patient who came to the surgery because of loose fixed prosthetic devices in the lateral region of periodontologically compromised frontal lower jaw. The patient had a total denture in the upper jaw with which she was satisfied. After radiographic treatment extraction of the remaining teeth was indicated and implantoprosthetic rehabilitation agreed. With the healing of the extractive wounds, a further orthopantomogram showed the possibility of inserting only four Ankylos implants in regions 46, 43, 33, 36. The patient expressed the desire to again have fixed prosthetic rehabilitation. As a compromise, at the end of osseointegration, the implants were loaded with a removable bridge on the telescope principle. The paper presents one of the methods of implantoprosthetic rehabilitation of the atrophic lower jaw.

Abstract:	Today osseointegrated implants and prosthetic superstructures represent a form of standard care for patients in whom there is the loss of one or all teeth in both jaws. Slowly but surely prosthetic devices, supported by osseointegrated implants, have taken prevailed over the advantages of conventional prosthetic techniques of treatment of complete or partial edentulousness. Indications for prosthetic devices supported by osseointegrated implants are: a) edentulous patients, b) patients with prostheses who cannot, or refuse to, wear mobile prosthesis, c) patients with unilateral edentulousness where it is impos-sible to construct fixed bridges of longer span, d) patients with poor muscular coordination and low tissue tolerance (simple term for attachment gingiva in the lower jaw), e) patients with periofunctional habits which destabilise conventional prostheses, f) patients with marked reflex to vomiting, g) unsatisfactory number and position of natural teeth as possible abutments, and f) loss of one tooth in order to avoid grinding of adjacent intact teeth. Absolute contraindications for placement of implants are: a) patients radiated with high doses, b) patients with mental problems, c) haematological system disorders. Relative contraindications are: a) pathology of soft and hard oral tissues, b) the area of fresh extractive wounds, c) patients using drugs, alcohol or tobacco (smoking or chewing of tobacco). Initial information received from each patient must include medical and dental history, radiographic finding (orthopantomograph or CT), analysis of study models and photographs, or with the purpose of achieving optimal treatment plan. The patient must understand the plan of treatment and be motivated for such treatment, while the clinician during diagnostic and therapeutic procedures learns about the mental - physical condition of the patient and acquires his/her confidence. The object of this presentation was to show the clinical laboratory course of the insertion of implants and construction of prosthetic devices in clinical situations of complete and partial edentulousness. Emphasis is placed on prosthetic systems such as a combination of telescope crown and attachment (CEKA type attachment) and individually milled bars, which optimise retention and stabilisation of the prosthetic device with the object of obtaining maximal function, aesthetics and patient satisfaction.

Abstract:	For decades clinicians have attempted to replace lost teeth by the insertion of alloplastic material in the bone and construction of prosthetic devices. The aim of the study was to examine and evaluate the functional durability of implantoprosthetic therapy in partially edentulous patients. During the period between 1997-2005 36 patients were selected on the basis of history data, radiographic analysis and clinical examination for fixed implantoprosthetic therapy. The number of implants and choice of fixed device depended on the individual situation, wish of the patient, cost of the device and also accessibility of a particular clinical procedure. Devices were waxed on study models and individual splints constructed. The results demonstrated that during the eight years 36 patients (21 women and 15 men) were treated, aged 16 - 75 (x=40.3) years. The most frequent indications were lack of teeth (22 patients) trauma (10), fracture of a non-vital tooth (2) and anodontia of a lateral incisor (1). Fifty-three implants were placed (50 ITI, 1 Ankilos, 1 Astra Tech and 1 Brane-mark). Twenty-eight individual crowns were constructed (16 MK, 7 FK and 5 AK) and 14 hybrid bridge constructions (10 metaloceramic and 4 of Au-Pt alloy and polymer veneer material). All devices were cemented. It can be concluded that the most frequent indications for implantoprosthetic therapy were aesthetic in female patients. As the response of patients to return for a check-up was negligible, it is difficult to assess the clinical condition of the above devices. However, it can be safely said that after 6 years of functional durability the success of therapy is 100%.

Abstract:	Without pre-extraction photographs or casts it is not easy to select suitable artificial teeth.The aim of this study was to determine the relationship between the width of frontal maxillary teeth and the width of the hard palate. The aim was also to determine the possibility of reconstructing maxillary frontal teeth dimensions, based on hard palate dimensions.Teeth and hard palate dimensions were measured on maxillary casts of 80 fully dentate individuals (26 men and 56 women) of Angle class I occlusal relationship.The maxillary central incisor is the widest among the frontal maxillary teeth and canines are wider than second incisors. The width of the maxillary frontal teeth arch, measured with a flexible ruler is 52.05 mm, hamular distance 47.1 mm, distal maxillary width 46.1 mm, sum of the widths of all maxillary frontal teeth 46.04 mm, frontal maxillary width 35.8 mm, and finally the width between canine cusp tips is 34.19 mm.Based on the results of this study, the sum of all maxillary frontal teeth widths is equivalent to hamular distance dimension, as well as distal maxillary width, as there were no statistically significant differences between them. After extraction of all teeth, distal maxillary width is lost, which is not possible to reconstruct because of the individual rate of alveolar bone resorption. On the other hand, hamular distance remains the same dimension during the lifetime, because it is not determined by teeth position but by anatomical structures. Therefore, the hamular distance dimension is a suitable reference for determination of the dimension of the sum of all maxillary frontal teeth widths.

MeSH:	CROWNS DENTAL MATERIALS
Abstract:	The demands of patients for high aesthetics during reconstructive prosthetic procedures accelerated the development of new materials and technology. Forces acting in the post-canine part of the dental arch amount to ≥ 500 N, and thus the material used for fabrication of the restoration must withstand such forces. The aim of this investigation was to study the resistance to fracture of three non-metal materials: 1. ceromer (Targis, Ivoclar-Vivadent), 2. ceromer reinforced with fibre reinforced composite (Targis/Vectris, Ivoclar-Vivadent), and 3. non-metal ceramic system (IPS Empress 2, Ivoclar-Vivadent). Eighteen identical crowns were fabricated from each type of material on a plaster model of a polished natural second lower premolar, according to the manufacturer’s instructions. The same tooth was used for fabrication of a metal model on which crowns were placed in the universal testing device ZWICK. The compressive plate was modified with a pin 7mm in diameter, which acted with force on the occlusal surface at an angle of 180˚. Force was applied up to the first sign of fracture, and the amount recorded.Half of the samples prior to the examination were thermocycled 1000x for 20 seconds at temperatures of 2˚C and 55˚C with 40 second intervals between immersion of the tempered sample. The mean value measured of the amount of force up to fracture for non-thermocycled samples amounted to 577.8 +/- 113.4 N for crowns of ceromer, 923.3+/- 229 N for crowns of ceromer and fibre reinforced composite, and 1208.9 +/- 161.8 N. for crowns of non-metal ceramic. Significant difference was determined by Mann-Whitney U test between all three materials (p < 0.05) for the amounts of loading up to fracture of the samples. Thermocycling did not significantly reduce the amount of force up to fracture of the sample. The investigation determined that all three materials are satisfactory for fabrication of permanent restorations in the area of the masticatory centre, as all withstand force greater than 500 N.
