Relationship Between Staging and Grading of Periodontitis and Periimplantitis: A Retrospective Study

Abstract

Objective: The purpose of this retrospective study was to determine the relationship between peri-implantitis and stage/grade of periodontitis. Methods: Records of 171 periodontitis patients with 318 dental implants were screened. Classification of diagnosed patients with periodontitis were done by both stage (1, 2, 3 and 4) and grade (A, B and C). Peri-implant health status was evaluated as no peri-implantitis or with peri-implantitis. Marginal bone loss severity of implants diagnosed with peri-implantitis, prosthesis type (single, bridge), location of dental implants (maxilla, mandibula, anterior and posterior), smoking (yes/no) and diabetes history (yes/no) of the patients were also evaluated. Analysis was done at implant level. Results: A total of 203 (63.8%) dental implants were diagnosed with peri-implantitis. There were statistical differences in the stage and grade of periodontitis between implants diagnosed with no peri-implantitis and peri-implantitis (p
