The Successful Treatment of Peri-implantitis with Guided Bone Regeneration with an 8-Year Follow-up: Case Report and Literature Analysis

Abstract

Replacement of missing teeth or unrestorable ones with dental implant-supported restorations is a substantial part of the clinical treatment protocol. However, with the increase in dental implants being placed worldwide, complications with this treatment have also risen in numbers. Complications may result from poor selection of cases with inappropriate treatment planning, occlusal overloading, or with poor follow-up care. The most common complications are the ones related to the presence of inflammation and include perimucositis and peri-impantitis. Peri-implantitis is an inflammatory condition that affects the soft and hard tissues around osseointegrated implants and results in the establishment of a peri-implant pocket and the loss of supporting bone. Nonsurgical therapy, the use of locally and systemically given antibiotics, and surgical regimens intended to replace the lost bone and soft tissue around the implants are among the documented treatment options. The aim of this article is to present a case report on the successful management of a case of peri-implantitis with nonsurgical and surgical approach following the ITI treatment protocol with a 5-year follow-up, along with a review of some of the treatment options used in their management.
