Abstract

Objectives: This retrospective cross-sectional study aimed to evaluate the prevalence of biologic complications of implants in patients treated by fixed implant supported prosthesis without regular maintenance program. Materials and methods: One hundred thirty-four patients with 478 implants, installed during a 10-year period (2001–2010), were recruited for clinical and radiographic follow-up examinations. The periodontal and implant health status were assessed to determine the prevalence of peri-implant diseases. Results: The mean ± SD loading time for implants was 4.43 ± 2.25 years. Fifty-five percentage of the implants were tissue-level implants. Peri-implantitis was diagnosed in 20% of patients and 8.8% of implants. Subject-based and implant-based prevalence of mucositis amounted to 48.5% and 40%, respectively. Mean crestal bone loss in tissue-level and bone-level implants were 0.28 ± 0.53 mm and 1.37 ± 1.5 mm, respectively. Smoking and lack of keratinized mucosa was associated with peri-implantitis at an odds ratio of OR = 2.57 and 3.89, respectively. Conclusions: After a 5-year period of loading without any regular maintenance program, one out of five patients would experience peri-implantitis. Tissue-level implants had lower values of peri-implantitis prevalence and crestal bone loss. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd
