Clinical outcomes of peri-implantitis treated with bone substitute and resorbable membrane: a literature review with a systematic approach

Abstract

Objective: The objective of this review was to evaluate the outcomes of the treatment of peri-implant defects, using Guided Bone Regeneration. Methods: A literature search was performed based on the PICO methodology in the PubMed/Medline, SciELO, Lilacs electronic databases, CAPES periodicals and the Cochrane Library. We included studies using bovine mineral matrix, associated to a collagen membrane for the treatment of peri-implantitis by Guided Bone Regeneration. Results: Of 1,163 studies, 10 were included in this review after applying the evaluation criteria. A total of 269 implants were treated in 260 patients. The follow-up period ranged from 6 to 48 months. The studies evaluated outcome in terms of reduction in probing depth, gain of clinical attachment and healing of the bony defect. Due to the heterogeneity of the studies, it was not possible to perform meta-analysis. Conclusion: Treatment of peri-implant lesions with Guided Bone Regeneration is a viable modality of treatment, providing reduction in bleeding on probing, as well as gain of clinical attachment. Complete filling of the defect is, however, an unpredictable result.

Main Approaches to the Causes and Treatments of Periimplantitis: A Narrative Review

“…Implants other than natural teeth are not vascularized, so peri-implant tissue responds differently to infections and masticatory forces. Most patients with peri-implantitis have already developed gingivitis, periodontitis, or mucositis, so, before installing the implants, the dental surgeon must pay attention to the way the patient maintains his oral hygiene and whether the current systemic health of the patient is in agreement to receive the implant and have a good result [4].…”
