Clinical Trends in the Prevention of Peri-Implantitis: Spanish Society of Periodontology (SEPA) Foundation Survey Using the Delphi Method

Abstract

Objective: To assess clinical trends to prevent peri-implantitis in applying a two-step survey based on the Delphi method.Material and Methods: A panel of participants aged < 45 years old selected by the Spanish Society of Periodontology (SEPA)was asked to answer a survey with 75 statements prepared by a steering committee. Items were divided into 5 major areas: eti-opathogenesis and epidemiology, surgical, implant, and prosthetic-related factors on the onset/progression of peri-implantitis,and self- and professional-administered oral hygiene. Degree of agreement or disagreement among participants was reported.Results: In total, 44 participants responded favorably to participate in the survey. From the 75 statements formulated, 35 wereagreed on in a first round (46.7%). From the 40 statements that did not reach consensus, 16 were agreed on in a second round(40.0%). Overall, 51 out of 75 statements (68.0%) achieved consensus in a second round. From these, 36 (48.0%) were in agree-ment, while 15 (20.0%) were in disagreement. The sections that explored surgical-related factors and prosthesis-related factorsof peri-implantitis yielded the highest level of conflict (9/18 and 8/14 statements demonstrated indeterminate agreement, re-spectively). In the sections on the etiopathogenesis and epidemiology of peri-implantitis and implant-related factors, most itemsreached consensus (14/17 and 10/13 items, respectively). The section on self- and professional-administered oral hygiene ob-tained the highest level of consensus, with only 1/13 items showing dissent among the participants.Conclusion: The results of this study on the clinical trends in the prevention of peri-implantitis showed consensus agreementfor ∼70% of the statements evaluated.
