Abstract
The main objective of this study is to present patient compliance rates and influential factors for regular attendance in a systematic implant aftercare program (Supportive Implant Therapy; SIT) within a 10-year observation period. From 2005 to 2008, we identified 233 patients with 524 implants and implant-supported restorations at the study center. They had been instructed to attend an SIT program with 3-month recall intervals. A 2019 clinical prospective cohort study on 10-year compliance rates was performed. Data were assessed yearly in regression analyses to identify influential factors. Noncompliance rates increased during the period (4.8%, year 1; 39.7%, year 10). Total noncompliance was observed in four patients (1.7%) with 10 implants. “Age,” “Gender,” “Diabetes”, and “Surgical case complexity” showed no correlation with patient compliance. “Smoking” and “Cardiovascular diseases” significantly influenced patients in one of ten years, while “Number of implants per patient”, “Type of implant-supported prostheses”, and “Pre-existing experience in a prophylaxis program” reached significance after several years. When patients with implant-supported restorations are strongly recommended and frequently remotivated to comply with an SIT program with 3-month recall, an approximately 60% compliance rate after 10 years is achievable. Previous prophylaxis program experience, increased number of implants per patient, and removable implant-supported prostheses may be strong influential factors for increased patient compliance.

Summary
Dental implants have developed to be a widely accepted concept of rehabilitation after tooth loss. Implants are exposed to the intraoral biofilm. They are at risk to develop peri-implantitis, an inflammatory disease analogous to periodontitis at natural teeth. Supportive periodontal therapy (SPT) has widely been accepted as an essential continuation after successful treatment of periodontal diseases. SPT has been proven to enormously contribute to the long-term preservation of periodontally compromised teeth [1,2,3]. Further tooth loss is described as a relatively rare event under sufficient SPT conditions [4,5,6,7,8,9,10,11]
