Patient-reported oral hygiene and implant outcomes in general dental practice.

Abstract

This study investigated the possible correlations between patient-performed implant hygiene and peri-implant success and disease, as well as patient-reported outcomes, in a community-based cohort. Fifty-one patients (78 implants) from two private general practices were surveyed on their dental implant treatment history, oral hygiene instructions (OHI) received, home hygiene habits and current implant concerns. Their dentition, plaque/calculus scores and clinical implant parameters were examined. Correlations between hygiene habits, risk factors, implant success and peri-implant disease rates were assessed. Implants had a patient-reported mean time in function of 6.7years. Floss (74.4%), interdental brushes (IDB) (44.9%) and mouthwash (39.7%) were commonly used, while 7.7% of implants were only cleaned by brushing. Over half (56.4%) of implants fulfilled the success criteria, 61.5% had peri-implant health, 24.4% had mucositis and 7.7% had peri-implantitis. Only brushing (P<0.001) and detectable plaque/calculus (P<0.001) were significantly associated with more peri-implant disease. Local prosthetic factors affecting cleaning accessibility significantly reduced implant success (P<0.001). Patients reported mixed recall of implant OHI, 7.7% of implants were aesthetically unsatisfactory and 9.0% had peri-implant symptoms. Lack of interproximal cleaning and the presence of plaque/calculus were significantly associated with peri-implant disease in a community-based general practice setting, and patients reported mixed recall of OHI.
