What the trial is, and whether it could suit you

Objectives: To compare the influence of pre-fabricated titanium abutments and customized milled zirconia abutments on implant biocompatibility and the peri-implant region, as well as on radiographic bone loss and oral health-related quality of life. Detailed Methodology: This study is a randomized controlled clinical trial designed to evaluate the biological and clinical behavior of standardized titanium abutments compared with customized anatomical zirconia abutments in single implant-supported posterior restorations. The present investigation represents the prosthetic phase of a previously conducted randomized clinical trial that evaluated dimensional changes following different alveolar preservation protocols in posterior regions (CAAE: 59208422.8.0000.5418). In the previous phase, participants underwent tooth extraction and alveolar preservation procedures, followed by implant pla
