NCT05712031

Brief 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.
