Peri-implant Tissues Changes for Different Abutment Shapes and Heights

The goal of this randomized clinical trial is to investigate the influence of supracrestal soft tissue on abutments of different heights (2-mm vs. 3-mm) and shapes (cylindrical abutment vs. concave abutment) on changes in the marginal bone level (bone loss and bone remodeling) in healthy, partially edentulous volunteer patients undergoing implant-supported rehabilitation. The main questions it aims to answer are: * Is there any difference in marginal bone loss for different abutment shapes and heights? * Do the shape and height of the abutment affect implant success? All participants will receive bone-level dental implants placed approximately 2-mm below the bone crest, each receiving a different type of abutment and researchers will see whether the shape and height of the abutment influence the success of the implant, periodontal probing depth (PPD), and bleeding on probing (BoP) comparing four groups of patients: 1. 2-mm high abutments with cylindrical shape. 2. 2-mm high abutments with concave shape. 3. 3-mm high abutments with cylindrical shape. 4. 3-mm high abutments with concave shape. Clinical and radiographic assessments will be performed at abutment placement, at definitive prosthesis placement, and at 1, 3, 6, and 12 months after loading to measure marginal bone loss and peri-implant parameters.
