Efficacy of Autogenous Bone Ring Transplant versus Cortical Bone Plate with Sticky Bone in Defective Socket Augmentation with Immediate Implant Placement (Clinical and Radiographic Study)

Aim: This study aimed to radiographically and clinically assess the efficiency of autogenous bone ring transplants versus cortical bone plates with sticky bone in augmenting defective sockets with immediate implant placement. Subjects and Methods: Randomized controlled clinical research has been performed on 12 cases with defective mandibular posterior sockets. Cases were equally separated into 2 groups: Group I received autogenous cortical bone plates from the retromolar area converted into sticky bone; Group II received bone rings harvested from the chin. Immediate implants were placed in both groups. Radiographic assessments using CBCT were performed preoperatively and at three and six months postoperatively to assess implant stability (ISQ), marginal bone level (MBL), bone density, and buccal bone dimensions. Results: Both techniques demonstrated effective outcomes in terms of implant stability, with no significant variance among groups. Mean MBL remained within acceptable limits (<1 mm) in both groups, and bone density improved over time. The bone ring group exhibited a slight advantage in terms of treatment time and bone quality, although differences were not statistically significant. Conclusion: Both techniques are reliable for three-dimensional augmentation and immediate implant placement in severely defective sockets. The bone ring technique may offer additional benefits in reducing treatment time and enhancing bone quality and implant stability.
