Objective:To find out factors influencing the compliance of supportive treatment of patients with periodontitis who have received implant restoration therapy.Methods:Patients who had completed periodontal and implant restoration treatment for more than 5 years in Department of Periodontology,Pe-king University Hospital of Stomatology were subjected to inclusion between March 2022 and August 2023.A questionnaire was compiled to gather the information including patients'basic information(gen-der,age,and educational background etc.),smoking habits,general health conditions,oral hygiene habits,willingness to undertake periodontal and dental implant supportive treatment,actual fact on sup-portive treatment recorded in medical records,whether medical advices were correctly remembered,and reasons affected them to implement supportive therapy.The questionnaires were handed out to the above patients and filled during the process of follow-up treatment.Chi-square test,univariate and multivariate analysis of Logistic regression were employed to explore the correlations of these factors and the patients'compliance.Results:In the study,92 patients and questionnaires were collected and analyzed.The re-sults indicated that oral hygiene habits and whether medical advices were correctly remembered had sig-nificant correlation with compliance(P＜0.05).Time constraint(47.0％)and difficulty in appointment registration(24.8％)were the top 2 reasons obstructed them to undertake supportive treatment.Al-though the vast majority of the patients indicated willingness to perform follow-ups,55.4％of them wouldn't come back until the dentist called them back.The results of our study also indicated that the patients placed significantly less importance on the health of natural teeth than implants.Conclusion:In order to improve the compliance of supportive treatment,we suggest that dentists should put more empha-sis on oral hygiene instruction,and knowledge regarding periodontitis should also be added as part of pa-tient education contents.In the early stages of treatment,the patient should develop the habit of regular follow-up checks,More attention and patience should be given to elderly patients and those with lower level of education;use language that is easy to understand and printed medical instructions to help them remember.Patients can memorize better from refined doctors'advice,reinforcing care knowledge and refining medical advices can promote better follow-up treatment results.Motivating patients based on their characteristics is critical to improving compliance.
