Bone regeneration as treatment of peri-implant disease: A narrative review
Abstract
INTRODUCTION: Analysis of the 3-dimensional implant position, the bone defect morphology, and the soft tissue situation guides the decision to preserve or to remove an implant with a severe peri-implantitis lesion. The aim of this narrative review was to analyze and to comprehensively illustrate the treatment options focusing on peri-implant bone regeneration in presence of severe peri-implant bone loss.
METHODS: A database search was performed independently by the two reviewers to identify case reports, case series, cohort, retrospective, and prospective studies about peri-implant bone regeneration with a follow-up of at least 6 months. Of the 344 studies issued during the database analysis, 96 publications were selected by the authors for this review.
RESULTS: Deproteinized bovine bone mineral remains the best documented material for defect regeneration in peri-implantitis in combination with or without a barrier membrane. While studies using autogenous bone in peri-implantitis therapy are rarely found, they do report favorable potential of vertical bone regeneration. Moreover, while membranes are an inherent part of the guided bone regeneration, a 5-year follow-up study demonstrated clinical and radiographic improvements with and without a membrane. The administration of systemic antibiotics is frequently performed in clinical studies observing regenerative surgical peri-implantitis therapy, but the analysis of the literature does not support a positive effect of this…
