| Abstract: |
Tricalcium phosphate -Ca3(PO4)2- is a resorbable and biocompatible calcium phosphate ceramic with the ratio of calcium and phosphate atoms very similar to natural bone mineral and consequently in the tissue it behaves like an autogenic bone transplant. It is gradually resorbed during remodelling of the bone and substituted with new osseous tissue. In oral surgery it is mainly used for large bone defects which develop during operations for cysts and tumours and in dental implantology. The purpose of the study was to present two cases of the healing of bone defects after operation of jaw cysts filled with granulate beta-tricalcium phosphate (Bioresorb Macro Pore - Oraltronics). The method was performed on hospitalised patients with their prior consent in the Department of Oral Surgery, University Hospital “Dubrava”. Bone defects were filled with the required amount of granulate, granules 1000 - 2000 µm in size. The results of healing were subjectively evaluated by analysis of radiographs after 2, 4 and 6 months and compared with the healing of a similar cavity after enucleation of a bone cyst treated by Partsch II method with permanent postoperative suctions. The preliminary results of the application of Bioresorb Macro Pore in the treatment of large mandibular cysts showed very good acceptability of the material, with no complications with regard to infection or problematic healing of the wound, and restoration of the bone structure was completed within a period of 4 and 6 months after the operation. The examples presented and their comparison with a third example support the application of resorbable tricalcium phosphate. By this method the anticipated bone structure is achieved faster than by other known methods. |

| Abstract: |
The paper presents two cases of clinical application of polyglycolicpolylactic co-polymer Fisiograft. In the first case periodontal abscess and damaged interradicular alveolar bone of tooth 46 was diagnosed. Interradicular damage to the bone was visible after opening the mucoperiosteal flap. Scaling of the root and careful elimination of the inflamed tissue was performed and the defect filled with Fisiograft implant (Ghimas S.p.A - Italy) in the form of gel and powder, moistened with blood and covered with a coronally positioned flap. Postoperatively the patient was advised to rinse her mouth with 0.2% chlorhexidine digluconate solution. The results of the treatment were monitored clinically and radiographically six months after the procedure. Probing the periodontal pockets before the procedure revealed a depth of 8 mm and loss of the level of periodontal attachment of 10 mm on tooth 46. Clinical evaluation six months after the procedure showed a reduction in the depth of the periodontal pocket from 8 to 4 mm and attachment level gain of 5 mm, which amounts to 50% of the original defect. In the second case, after raising the mucoperiosteal flap of tooth 21, an extensive intrabony defect was revealed, which involved several bony walls. After scaling and planing the root we filled the defect with a Fisiograft implant in the form of gel and powder, moistened with blood. Because of the activity of the periodontal pocket we prescribed Amoxicilin tablets 500 mg, 3 times daily for 5 days. Postoperatively, the patient was advised to rinse his mouth with 0.2% chlorhexidine digluconate solution. Six months after the procedure the clinical finding showed reduced depth of the periodontal pocket and gain of attachment level 4 mm, i.e. 44.5% of the original clinical defect. The radiograph showed reduced radiolucency of the alveolar bone of tooth 21, indicating the formation of new supporting alveolar bone. Thus, it can be said that the application of Fisiograft proved to be successful in regeneration of the alveolar intrabony defect. Six months after the procedure the radiograph showed considerably reduced radiolucency and depth of the periodontal pocket was reduced by around 50%.In the presented two cases the application of Fisiograft proved successful in the process of healing alveolar bone, damaged by periodontitis, and it is therefore proposed that this implant is applied in a larger number of subjects and further investigation carried out. |
