Official title
Effect of Collagen Membrane on Ridge Preservation for Delayed Implant Placement in Sites With Absent Buccal Bone Wall: A Randomized Controlled Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate whether adding a resorbable collagen membrane to an anorganic bone-collagen composite (ABCC) graft improves ridge preservation after tooth extraction. Ridge preservation is a procedure used to maintain the shape and volume of the jawbone following tooth removal, which is important for future dental implant placement. Participants will be randomly assigned to receive either ABCC alone or ABCC combined with a collagen membrane. Healing outcomes will be assessed after approximately 4 months using three-dimensional cone beam computed tomography (CBCT) scans. The primary outcome is the change in horizontal ridge dimension (width). Secondary outcomes include vertical and contour changes in ridge dimensions, changes in soft tissue contour assessed with digital scans, postoperative healing and complications (such as wound dehiscence, swelling, or infection), and patient-reported outcomes, including pain and satisfaction. In a subset of participants, bone healing will also be evaluated using laboratory and imaging analyses of bone samples obtained at the time of implant placement. The study will additionally assess whether the treatment allows implant placement in the ideal position without the need for further bone grafting.
