Abstract / Introduction: Peri-implantitis is defined as an inflammatory process that affects the bone tissue around osseointegrated implants and may therefore be a cause of dental implant failure. Objective: The objective of this study was to evaluate dentists’ knowledge of the diagnosis and treatment of peri-implantitis using a questionnaire applied to dentists from the towns of Cascavel and Maringá, State of Paraná, Brazil. Methods: The sample consisted of specialists in Implantology. The same researcher explained and applied the questionnaire. With respect to the clinical characteristics of peri-implantitis, 33% of the respondents associated the condition with inflammation, 28% with radiographic bone loss around the implant, 26% with bleeding, 24% with the presence of plaque and calculus, and 5% with implant mobility. Approximately 16% of the respondents were unable to answer the questions related to peri-implantitis. Results: In the presence of a diagnosis of peri-implantitis, the most frequently used treatment was maintenance by peri-implant curettage, followed by antibiotic therapy. More than half the dentists suggested surgical treatment of peri-implantitis by guided bone regeneration combined with bone grafting. Eighty percent of the respondents considered the failure rate of osseointegration to be related to the surface, shape and material of the implant. Conclusion: We conclude that diagnostic methods and treatment modalities of peri-implantitis should be further clarified by scientific literature, since this study showed a lack of knowledge of dentists regarding specific aspects related to peri-implantitis.
