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.",[27],"Alveolar Ridge Deficiency",[29,30,31,32,33],"Guided Bone Regeneration","PEEK membrane","PTFE membrane","Ridge augmentation","Maxillary ridge augmentation","RECRUITING","2026-06-25",{"date":37,"type":38},"2026-07-01","ACTUAL",{"date":40,"type":38},"2026-01-01",{"date":42,"type":21},"2027-02-01",{"name":44,"class":45},"Mansoura University","OTHER"]
