Sažetak
Background: Along with the development of surgical techniques there has been expanding indications for dental implant placement, and consequently extended range of possibilities for the development of contemporary fixed prosthetic dentures (FPD) which include bridges on dental implants, teeth and their combination. Aim/Hypothesis: The aim of this study is to assess the success of FPD on teeth, implants, and their combination by studying the incidence of biological and technical complications for the function period of 1–3 years (average 2.3 years). Material and methods: Sixty partially edentulous patients provided with a fixed bridges in posterior areas of the maxilla and mandible. Bridges are two-unit, three-unit and four-unit without pontics. Bridges are worn by teeth, implants and their combination and the patients were divided into three groups. All implants were Astratech, screw shape, length of 9 to 13 mm. Both clinical and radiological examinations were done which determined the incidence of biological and technical complications. Groups of variables were used to form three different index values which were compared using ANOVA. Multiple regression analysis was used to test the effect independent variables on the dependent variables. Results: Index of biological complications (mucositis, periimplantitis, gingivitis, periodontitis and pulpitis) shows the highest value on bridges worn by teeth and the lowest on bridges worn by implants. Index of occlusal complications (occlusal concepts, parafunction, premature contacts) had the highest value on bridges worn by implants. Index of technical complications (implant or abutment breakage, screw loosening, bridge debonding, fracture of ceramics) has the highest value on bridges worn by combination of teeth and implants and the lowest value on bridges worn by implants. ANOVA found that there was no statistically significant difference in the incidence of biological and technical complications between groups. Multiple regression analysis tested the impact of clinical and radiological findings (bone resorption and bone density, occlusal factors, general health, oral hygiene) on the incidence of biological and technical complications. It showed that the greatest impact has bone resorption around the implant, except for bridges worn by teeth which were mostly affected by occlusal index. Conclusions and clinical implications: The results of this study are consistent with the recen scientific literature. They indicate that, in the long term, the greatest impact on the success rate of FPD worn by implants and combination of teet-implant have biological complications, and they are due to the expanded range of indications for implant-prosthetic treatment of patients, occurring in a growing percentage.
