title: A retrospective study to compare improvement of implant maintenance by Medical Treatment Model.
abstract: BACKGROUND
  Study comparing the improvement of implant maintenance is limited. Clinicians must be aware of implant maintenance to improve long-term success of implant.
  
  
  OBJECTIVE
  The aim of this retrospective study was to evaluate whether the Medical Treatment Model (MTM), which is a comprehensive treatment, includes initial risk assessment, lifestyle instructions, such as diet and habits, and a customized maintenance program to improve implant prognosis.
  
  
  METHODS
  Patients who were comprehensively treated were included and divided into two groups, test and control groups. The test group included patients who started treatment with MTM, whereas control group included patients who started treatment without MTM introduction. Moreover, subsequently, compliance with maintenance, occurrence of biological complications, and implant failure were evaluated.
  
  
  RESULTS
  About 199 patients with 515 implants were analyzed in the control group and 38 patients with 59 implants in the test group. In the control and test groups, the percentages of patients in the four compliance categories were, respectively, 73.9% and 89.5% for excellent compliance, 7.0% and 7.9% for good compliance, 14.6% and 0% for fair compliance, and 4.5% and 2.6% for poor compliance. There was a statistically significant difference in the compliance with periodontal and implant maintenance between the test and control groups (P= 0.029).
  
  
  CONCLUSIONS
  Within the limitation of this study, MTM significantly enhanced the compliance of patients treated with implants.
