A Descriptive Study on the Prevalence of Peri-Implantitis with Severe Disease and Bone Loss

Abstract

Background: Peri-implantitis is a common complication in dental implant. It is associated with peri‐implant pocket formation and loss of supporting bone which hinder the treatment of replacement of missing teeth in partially or fully edentulous patients. Aim of the Study: The aim of this study was to assess the prevalence of peri-implantitis with severe disease and bone loss. Methods: This descriptive study was conducted in the post oral implant care unit of Banasree Dental and Implant Center and German Dental & Implant Center, Dhaka, Bangladesh during the period from February 2013 to January 2022. The sample size of this study was 99. Result: Among 99 study people, mean age was 56.4 years (SD±8.1 years). Majority of the study people (53.5%) were female. From the past history, we found that 21.2% study people had smoking habit, 19.2% had diabetes, 11.1% had hypertension, 39.4% had history of periodontitis, 6.1% had osteoporosis, 2% had history of chemotherapy and 1% had history of radiotherapy. Mean follow-up was 920 days (SD±37 days). Mean implant width was 4.1 mm (SD±0.5 mm) and mean implant length was 11.0 mm (SD±0.6 mm). Most of the implants (63.6%) were located in posterior site. Mean longitudinal bone changes in mesial part were 3.0 mm (SD±4.2 mm). Mean longitudinal bone changes in distal part were 3.4 mm (SD±5.6 mm). Mean marginal bone loss was 4.3 mm (SD±3.3 mm). Mean probing depth was 4.2 mm (SD±2.1 mm). Conclusion: Older people specially women are more affected by peri-implantitis. Smoking habit, several diseases and history of periodontitis are associated with more risk for peri-implantitis. We have found peri-implantitis patients associated with severe bone loss and deep probing depth.
