Overview
Brief Summary
This randomized clinical trial aims to compare the stability, survival, and marginal bone loss of two implant abutment connection Conical Hex Morse taper and Step butt joint in screw and cement retained restorations. A total of 80 patients are divided into two parts 40 with a single mandibular molar missing and 40 with two posterior teeth missing. Each part has subgroups based on implant type and retention method. Diagnostic records, CBCT, and intraoral scans are used for planning. A delayed loading protocol is followed, with follow-up at 3, 6, 12, and 24 months. Bone loss is measured radiographically stability via ISQ values. Statistical analysis will be done using SPSS with ANOVA Kruskal Wallis and post hoc tests. The study aims to guide clinicians in selecting optimal implant-abutment systems for long-term success.
