Surgical Treatment of Peri-implantitis Using a Bone Substitute With or Without a Resorbable Collagen Membrane

United States52 participantsStarted 2023-01-30

Plain-language summary

The objective of the present randomized clinical trial will be to compare two surgical methods of treating peri-implantitis. This study will determine if surgical debridement of peri-implantitis bone defects, including air powder abrasive (APA) decontamination of implant surfaces, in combination with the placement of a bone graft, differs in treatment outcomes compared to placing the same bone graft material with a resorbable collagen membrane placed over the bone graft.
