Reconstruction of Deficient Atrophic Ridges Using Guided Bone Regeneration Technique With Native Collagen Membrane and Polytetrafluoroethylene Membrane (Randomized Clinical Trial)

What this Trial Is About

This research evaluates two bone regeneration techniques for patients needing ridge augmentation or bone augmentation in the upper jaw. It compares a mixture of autogenous and xenogenic bone covered either by a polytetrafluoroethylene (PTFE) membrane or a native collagen membrane. Patients are randomly assigned to one of these two groups to study the effectiveness of these membranes in bone healing after ridge augmentation. Both groups undergo similar surgical procedures involving local anesthesia, creation of a mucoperiosteal flap, harvesting autogenous bone using an auto chip maker, and mixing it with xenogenic bone in a 1:1 ratio. This bone mixture is placed in the recipient site and fixed with titanium bone tacks. The control group’s bone assembly is covered with a PTFE membrane, while the study group’s assembly is covered with a resorbable collagen membrane. After surgery, the flap is closed carefully to ensure tension-free healing. Participants have diagnostic CBCT scans for the upper arch before surgery and again four months after the procedure to measure bone gain. They receive diagnostic wax-up and stent fabrication as part of the preparation. Researchers monitor soft tissue healing starting one week after surgery, noting any wound dehiscence. The main outcome measured is the quantity of bone gained after four months. The entire study period spans from initial screening through four months of follow-up.
