Resin-Bonded Prosthesis in Posterior Area to Prevent Early Marginal Bone Resorption in Implants Placed at Tissue Level

Aim: To evaluate the effect of resin-bonded prosthesis (Maryland bridge) on marginal bone remodeling implants placed at tissue level in posterior region. Methods: Consecutive healthy patients (n = 46) were included this clinical study. Flapless not-submerged with cover screws exposed and positioned approximately 0.5 mm above level. Patients received implant a temporary (RBP) 22) or only 24). The RBPs kept place for 3 months removed before impressions. custom-made abutment provisional resin crowns followed by definitive cemented metal–ceramic after 2–3 weeks. (MBL) was evaluated single-blind condition scanned periapical radiographs assessed mesially distally (MBL-M/MBL-D). levels adjacent teeth (CEJ-M/CEJ-D) modification area between mesial/distal (Area-M/Area-D) measured. All measurements made 1, (pre-loading time) 12 (post-loading time). Linear regression models fitted to existence any significant difference. Results: A total 44 (20 Female, 24 Male; Mean age: 53.9 ± 10.3) completed Two excluded fractured RBP de-bonding. drop-out 4.3%. After months, all free from complications. No peri-implantitis mucositis observed. group showed most stable MBL (−0.07 0.41), statistically different non-RBP (−0.67 0.52). CEJ-M CEJ-D both groups. Conclusion: proposed approach use creates more around level, resulting reliable technique protect mechanical occlusal trauma during healing period osteointegration.
