Comparing Maxillary Ridge Reconstruction Using Retromolar Bone Blocks With and Without Collagen Membrane

What this Trial Is About

Researchers are evaluating whether using a collagen membrane on top of a particulate bone mixture covered by an onlay bone block in the maxilla improves bone quantity compared to using the mixture and bone block without the collagen membrane. The study aims to address complications like soft tissue dehiscence that can affect bone stability and integration. It also examines barrier membranes ideal qualities, such as biocompatibility, nutrient diffusion, and tissue integration, using collagen membranes like Geistlich Bio-Gide or Jason Membrane Botiss. Participants receive treatment involving onlay bone blocks harvested from the retromolar region, fixed with micro screws. In the experimental group, the bone block and particulate bone mixture are covered with a native collagen membrane fixed with titanium bone tacks. The control group receives the same bone block and particulate bone mixture without collagen membrane coverage. This randomized clinical trial compares these two procedures to evaluate bone gain. During the study, participants are monitored for bone quantity gain at 5 months after ridge augmentation, which is the primary outcome measure. Researchers also assess soft tissue dehiscence at baseline and one week after treatment. The study includes assessments of bone stability and soft tissue healing. Participants aged 20 to 40 years with specified maxillary bone conditions are involved, with follow-up evaluations to measure outcomes and safety.
