Comparing Resorbable Pericardium and Non-Resorbable PTFE Membranes for Bone Regeneration in the Lower Back Jaw in Patients Needing Horizontal Bone Augmentation

What this Trial Is About

Researchers are comparing the effectiveness of non-resorbable membranes versus resorbable membranes in guided bone regeneration for patients with bone loss in the lower back part of the jaw posterior mandible. This study addresses challenges like bone loss due to periodontal disease, tooth extraction, or prolonged use of dentures, which can make implant placement difficult. The goal is to improve bone regeneration methods in this area to support dental implants. Participants will receive one of two treatments either a resorbable pericardium membrane or a non-resorbable polytetrafluoroethylene PTFE membrane. Both membranes will be fixed with titanium pins or tacks to the jawbone, covering a mix of bone graft material made of half xenograft and half autogenous bone. The graft is overfilled to account for future resorption and covered tightly by the membrane to stabilize and promote new bone growth. Throughout the study, participants will undergo clinical and radiographic exams including CBCT scans before and six months after surgery to measure bone thickness, height, and gain. Postoperative pain and discomfort are tracked with questionnaires for seven days. After six months, a biopsy will be taken to analyze new bone formation. Complications such as infections, membrane exposure, and implant stability will also be monitored. The study lasts at least one year with follow-up visits to assess outcomes.
