Summary

The goal of this clinical study is to evaluate clinical performance of combined tooth-implant supported 3 unit fixed partial dentures in the posterior mandible and was to compare and evaluate them with the complications of 3 unit fixed partial dentures supported with free standing dental implants.The main question\[s\] it aims to answer are: 1.Is there any difference in terms of mechanical and biological complications as well as marginal bone level between free standing and combined tooth-implant supported 3 unit Fixed Partial Dentures in posterior mandible. Participants will receive either 2 dental implants(Control group) or 1 standart length dental implants to be combine with abutment tooth or 1 short dental implant to be combine with abutment tooth for supporting 3 unit fixed partial dentures.

Detailed description

Purpose: The aim of the study was to evaluate clinical performance of combined tooth-implant supported 3 unit fixed partial dentures in the posterior mandible and was to compare and evaluate them with the complications of 3 unit fixed partial dentures supported with free standing dental implants. Material and methods: 78 partially edentulous patients in the posterior mandible (Kennedy 1 and Kennedy 2), age between 18-65 with no systemic disorders were recruited for the study (n=26). Group 1served as control group and received 2 dental implants for supporting 3 unit fixed partial dentures (FPD). In group 2 dental implants longer than 8 mm and in group 3 shorter than 8 mm were inserted to replace first or second molar combined with first or second premolar respectively to support cement retained 3 units FPD. Periapical radiographs were taken with parallel technique for evaluation of marginal bone resorption (CBL) and modified plaque index (MPI), bleeding index (BI) and sulcus depth of abutment teeth was recorded at the time of FPD insertion, 6 months after FPD insertion and annually. Abutment tooth intrusions, de-cementation of the restoration, porcelain chipping/delamination, framework fracture, abutment screw loosening, abutment and abutment screw fracture, implant fracture were also recorded as complications.
