Abstract:	Bilateral cleft lip and palate is a congenital malformation characterized by morphologic changes and deficiencies of soft and hard tissues in oral and maxillofacial region. Surgical correction usually takes place in childhood, but some problems can show up later. Beside the essential hypodontia in the cleft region, tooth loss due to other etiologic factors can contribute to edentoulism in adult patients. We present a case of 52-years old male patient with bilateral CLP. After surgical correction in the childhood, patient led a normal life with compensated function of the stomatognathic system. Problems arised, when he lost his last four maxillary teeth that supported his denture. Due to particular morphology of the ridges, removable prosthetic solution was only partly satisfying his needs. After consultation with the prosthodontist, we decided for implant supported solution. Preliminary dental CT showed atrophic bony ridges that excluded the possibility of orthotopic implant placement. As the patients resources were limited and extensive sinus lifts were out of his range, we decided for a compromise: autologous retromolar bone graft to the left premolar region, where we were facing the least bone quantity, was performed first. The gained bone volume was established on an additional dental CT and computer aided planning, was performed for placement of four maxillary implants. Planning culminated in fabrication of mucosa supported surgical guide (Simplant, Materialise) and was followed by successful placement of the implants. We conclude that computer aided planning and guided implant surgery make the extreme surgical precision possible and predictable. This is of utmost importance in situations with scarce bone quantity, where every millimeter of residual bone can be a landmark between failure and success.

Abstract:	Immediate implantation should be a procedure with predictable outcome. But for any elective surgery in the mouth, acute inflammation is regarded as contraindication. Our goal was to establish whether acute inflammation can adversely affect implantation outcome. Nine implants were immediately placed and prosthetically restored in eight patients (6 female, 2 male). In the group of inflamed socket (ISO) four implants in four patients were implanted in maxilla where at least one clinical sign of inflammation was present: fistula with pus (three sockets) and evident mucosal swelling (one patient). Other five implants (3 in the maxilla and 2 in the mandible) in four patients were placed in sockets without inflammation (NISO). Reasons for extraction were: root fracture, root resorption after luxation injury and failure of treatment of chronical periapical periodontitis. Surgical procedure was pointed toward preservation of tissues, curettage and gaining of primary stability. The void between the socket and the implant was filled with deproteinized bovine bone granules. Temporary crowns were delivered without any occlusal contact (non-functional loading). Antibiotic was prescribed for 10 days. Clinical and radiographic controls were performed according to the protocol (1/6/12/24 weeks). Survival rate was 100% in both groups. Regarding other criteria, all the implants were successful. With eight implants apposition of bone was seen over the implant shoulder on x-rays after 24 weeks, with one from NISO only unilaterally. Fistulas were closed in two weeks. With one patient postoperative hematoma emerged and resorbed uneventfully. Although lover survival and success rates were expected with the ISO group, this was not the case; bony overgrowth is even suggesting the opposite. Accurate aseptic surgery, removal of inflamed tissues and appropriate antibiotic obviously overweighed the threat of non-integration due to infections. This pilot study should be continued to prove these early results.

Abstract:	The conical crown was introduced more than twenty years ago, as a development of the well-known telescopic crown. It can be a very useful solution for immediate implant retained prosthodontic rehabilitation in the mandible. It is one of the standard treatment concepts that offers immediate stabilization of pre-existing denture and is regarded far from experimental today. It enhances comfort to the patient and reduces the number of surgical steps. Although more and more patients ask for an accelerated implant treatment, sometimes additional costs or presumed safety hazards can discourage them. In such situations, late restoration is also viable option. In the last two years, we have been treating 8 patients (5 male, 3 female) with complete mandibular edentoulism by placing four interforaminal implants. In 5 patients, immediate restoration on prefabricated conical crowns was delivered by the use of preexisting dentures that were replaced by a new, metal reinforced denture 3 months later. In 3 patients implants have been loaded 3 months after implantation, after a period of submerged healing. Both groups were similar regarding bone quality, implant length and width, age of the patient, but immediately placement of implants was more common in immediate loading group. The implant success and survival rate was the same in both groups (100%). No postoperative discomfort was reported by patients with immediate loading and bone resorption rate did not differ between the groups. With this retrospective study, we have proved same results with immediate and late loading of implants that supported mandibular dentures on conical crowns. It seems that such a solution splints the implants in the healing period perfectly and it does not interfere with oral hygiene. We believe that such a way of immediate loading can be recommended without limited safety for the patient.

Title in English:	Early Clinical Results of Immediate Placement of Dental Implants into Extraction Sockets

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.
