About

The aim of this study will be to evaluate the marginal bone loss and prosthetic complications of stress-free implant (SFI) and milled bars used to assist mandibular 4-implant overdentures after 3 years

Full description

Eight edentulous participants with insufficient stability of mandibular dentures will receive 4 implants in the mandibular ridge (2 implants in the canine areas and 2 implants in the first molar areas), and then after 3 months, patients will be randomly assigned into 2 groups; 1) group 1: will include 4 participants who will receive milled bar overdentures, and 2) group 2: will include 4 participants who will receive SFI bar overdentures. For both groups, marginal bone loss will be evaluated using the standardized digital periapical films at the time of insertion, 6 months, 1 year, and 3 years after insertion. Prosthetic and mucosal complications will be evaluated after 3 years.
