Abstract

Abstract : Objective: To evaluate the long-term incidence of complications in abutment teeth and dental implants in periodontally treated and maintained patients, refusing bone grafting surgical therapies, rehabilitated with full-arch telescopic-retained retrievable prostheses (TRPs) and full-arch fixed prosthesis (FPs), both supported by teeth-implants combination. Materials and Methods: After active periodontal therapy, 18 patients were rehabilitated with full-arch TRPs, whereas 17 patients were rehabilitated with full-arch FPs. Patients were annually evaluated for technical and/or biological failures/complications. Results: During the 15-year observation period, 6 of 164 (3.6%) implants failed and 19 of 233 teeth were extracted (9.2%) in the TRPs group, whereas 6 of 152 (3.9%) implants failed and 23 of 221 (10.4%) abutment teeth were extracted in the FPs group. Differences in implant failures and abutment teeth loss between the 2 groups were not statistically significant. In both the groups, Cox regressions identified significant difference ( P < 0.05) for mean initial bone loss, aggressive periodontitis, and smoking, as factors contributing to tooth loss and implant failures in general. Conclusion: In periodontally treated patients, refusing bone grafting surgical therapies, rehabilitated with full-arch TRPs and full-arch fixed prostheses, both supported by teeth-implants connection, high survival rates can be expected if regular supportive periodontal therapy had been performed.
