Supportive post‐implant therapy: patient compliance rates and impacting factors: 3‐year follow‐up

AIM: To evaluate patient compliance rates and influential factors regarding a systematic SIT program. MATERIALS AND METHODS: Between 2005 and 2008, we identified all patients who were provided with implant-supported restorations in the study centre. They had been recommended to attend a SIT program with a 3-month recall. In 2012, a clinical retrospective cohort study on compliance rates over the first 3 years was performed different data were assessed in a regression analysis to identify potential influential factors. RESULTS: The inclusion criteria were met by 236 patients with 540 implants. Non-compliance rates increased over the 3 years (5.37%/7.78%/13.33%). Total non-compliance was observed in four patients (1.69%). No correlation to patient compliance was detected for "Age," "Gender," "Cardiovascular disease," "Pus/suppuration," or "Surgical case complexity." No decreasing effect of higher compliance rates on the patients' bleeding on probing (BOP+) values was found, but a statistical significance between lower compliance rates and increased pocket probing depth (PPD) was detected. The correlation between the presence of plaque and compliance did not reach statistical significance. CONCLUSIONS: When patients with implant-supported restorations are strongly recommended to comply with a SIT program with a 3-month recall, considerably high rates of compliance can be achieved.
