Objective: The purpose of this study was to investigate the clinical criteria periodontists consider to maintain a periodontally-involved tooth versus replacement of the tooth with an implant. Decision-making criteria were investigated using a Delphi study. Materials & Methods: A questionnaire was developed by the Division of Periodontology to determine which factors are important in the decision to maintain a tooth or extract it and replace it with an implant. More specifically, periodontal factors, general clinical factors, and patient-centered factors were considered important criteria to investigate. Using the Delphi method, two rounds of questionnaires were mailed to prescreened, active Diplomats of the American Board of Periodontology in the United States, who had agreed to participate. Responses were analyzed and results presented as frequencies or averages, depending on the data that were collected. Results: 25 periodontists agreed to participate and 12 completed both rounds of questionnaires. The two most important factors for replacement of teeth with dental implants, in order, were identified as bone loss and tooth mobility. Minimum criteria for bone loss and tooth mobility that would result in extracting and replacing a tooth were: 70% bone loss with no tooth mobility; 60% bone loss with Grade 1 or 2 tooth mobility; 40% bone loss with Grade 3 tooth mobility; probing depth of at least 7 mm, and Grade III furcation involvement. When planning an implant case, panelists were concerned primarily about esthetics for anterior teeth, malocclusion for posterior teeth, and patient satisfaction. Treatment costs were not a major concern. Conclusion: The clinical criteria for implant placement suggest that periodontists select removal of teeth that are significantly affected by periodontal disease.
