Custom-Made PEEK Versus PTFE Membranes in Maxillary Alveolar Ridge Augmentation

This randomized controlled clinical study aims to evaluate and compare the effectiveness of custom-made polyether ether ketone (PEEK) membranes versus polytetrafluoroethylene (PTFE) membranes in guided bone regeneration for maxillary alveolar ridge augmentation in the esthetic zone. Thirty patients requiring ridge augmentation prior to dental implant placement will be enrolled and randomly allocated into two equal groups. Group A will receive customized PEEK membranes, while Group B will be treated with PTFE membranes. Clinical and radiographic assessments, including cone beam computed tomography (CBCT), will be performed immediately postoperatively, at 6 months, and at 12 months to evaluate volumetric, horizontal, and vertical bone gain as well as soft tissue healing and complication rates.
