Retrospective long-term evaluation of dental implants in totally and partially edentulous patients: part II: periimplant disease.

Abstract

This retrospective longitudinal study aims to assess long-term outcomes of osseointegrated dental implants placed in partially and totally edentulous patients. Patients who were willing to sign the informed consent and attend a check-up were included. The prevalence of periimplant disease was calculated. Cases were further divided into mucositis or periimplantitis. Uni- and multi-variate statistical analyses were conducted to determine the influence of various factors. A total of 105 patients who had received 342 implants were included. Mean follow-up was 13.19 ± 3.70 years. The prevalence of periimplant disease was 14.2% of the analyzed implants and 21% of patients. An additional 4.8% of patients reported a previous presence of periimplant disease without current disease. The prevalence of mucositis and periimplantitis was 11.2% and 1.7%, respectively, of analyzed implants. Factors with possible influence on the presence of periimplant disease were gender, alcohol consumption, chemotherapy and/or head and neck radiotherapy, history of periodontal disease, and years of function. In our sample, periimplant disease was not infrequent, being present in 1 of 5 patients at the final check-up.
