Comparing Marginal Bone Loss for Immediately Loaded Implants in Maxillary Full Arch Interim Prosthesis Using Welded Titanium Bar Versus Polyetheretherketone Bar

Fourteen completely edentulous patients will be randomly allocated into two parallel arm groups. For both groups virtual implant planning will be done and surgical guide will be planned and printed. An immediate interim full arch PMMA prosthesis will be virtually designed and printed for both groups. For the Intraoral welding group, seven patients will receive immediately loaded interim fixed full arch prosthesis splinted by intraoral welded bar. While for PEEK group in which seven patients will receive immediately loaded interim fixed full arch prosthesis splinted by PEEK bar. Marginal bone loss will be clinically evaluated at four, six months follow up period using CBCT.
