| Popis: | Objectives. The objective of our study was the retrospective assessment of the failure rate of implant-prosthetic treatment in a group of patients in correlation with Renouard-Rangert biomechanical scoring 2 years after prosthetic loading. Material and method. The study material was represented by the data taken from the observation and treatment sheets of 323 patients. After applying the inclusion and exclusion criteria from the study, 297 observation and treatment sheets were selected, from which were taken data that were processed and statistically correlated with Microsoft Excel 2016. Results. The final group included 127 male patients and 170 female patients, aged between 25 and 74 years. The 55-64 age group was best represented, and the location of the edentulous gaps was predominantly unimaxillary (236 unimaxillary edentulous patients vs. 61 bimaxillary edentulous patients). 1627 implants were inserted, of which 47 did not have a secondary stability favorable to prosthesis and were explanted. After applying prosthetic restorations, patients presented for control every 6 months in the first year and then annually. The complications of the implant-prosthetic therapy instituted were represented by decimation, loosening of the fixing screws, fracture of the physiognomic component or bone resorption passing through the first coil of the implant. Discussions. In the studied group, although the Renouard-Rangert biomechanical score initially calculated was "green", at 2 years there were complications in 23.9% of patients, mainly due to the development of parafunctions or changes in the occlusion plan, as a result of dento-periodontal damage to other masticatory units. The change in biomechanical scoring was found mainly in women (48 cases, representing 67.6%). To validate the results, we recommend extending the batch and the dispensing period. Conclusions. The high percentage of therapeutic complications that occurred at 2 years that determined the change of the Renouard-Rangert biomechanical score (95.77%) demonstrates a statistically significant correlation between the 2 parameters. |
