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.
The purpose of the study is to compare treatment outcomes of peri-implantitis defects when using a defect fill substitute (InterOss Collagen), against the treatment outcome when placing the same defect fill substitute with a resorbable collagen membrane (InterCollagen Guide). There is no current literature to suggest that placing a collagen membrane over a bone grafting material in an infrabony defect of more than 270 degrees is more effective than placing the bone graft material alone. The present study will help in understanding if such defects require an additional placement of a collagen m…
Inclusion Criteria: To be enrolled, the participant must meet the following inclusion criteria: 1. age 18 years or older 2. be patients of record at the University of Pittsburgh Periodontics Department 3. Systemically healthy patients 4. Full-mouth plaque score and full-mouth bleeding score ≤ 30% (measured at six sites per tooth) 5. Study individuals will be included if they met the following criteria: (a) one or more peri-implant sites with PPD ≥6 mm combined with BOP/suppuration, and (b) peri-implant marginal bone loss, defined as a crater like defect ≥3 mm as assessed from intra- oral radi…
