Comparing Fixed and Non-Fixed Resorbable Collagen Membranes for Guided Bone Regeneration to Help Dental Implant Placement

What this Trial Is About

Researchers are evaluating horizontal bone gain in patients with resorbed ridges needing Guided Bone Regeneration GBR to support dental implant placement. This clinical trial compares two methods of using resorbable collagen membranesone group receives non-fixed membranes, while the other group receives fixed membranes secured with pins. The goal is to see which method better supports bone growth over a 6-month period after treatment. Participants receive horizontal GBR using a bone graft made from a 5050 mix of xenograft and allograft bone substitutes. One group has the collagen membrane placed without fixation control, while the other group has the membrane fixed with non-resorbable pins test group. Both procedures involve covering the graft area with a Jason membrane measuring 20x30 mm. The study is randomized and compares the outcomes between these two approaches. During the study, participants will undergo assessments including measurement of horizontal bone gain and bone width gain at 6 months post-procedure. Other evaluations include checking the stability of the bone dimensions, monitoring any post-surgical complications from surgery up to 6 months, assessing patient satisfaction two weeks after surgery, and conducting histologic examination of the augmented bone at implant placement. The study is sponsored by the Universitat Internacional de Catalunya and participation may last about 6 months with follow-up visits and evaluations.
