Abstract
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.
Highlights
Peri-implant diseases are defined as infectiousinflammatory lesions that develop in the tissues around the implants, and are currently considered an emerging problem [1,2]
Peri-implant mucositis is defined as a reversible inflammatory reaction of the soft tissues that surround the implant in function, whereas the peri-implantitis is an inflammatory reaction associated with loss of bone support around the implant in function [4]
For the diagnosis of peri-implantitis, in addition to bleeding on probing, it is necessary to combine it with an increase in probing depth associated with bone loss around implants [6,7,8,9,10]
Summary
Peri-implant diseases are defined as infectiousinflammatory lesions that develop in the tissues around the implants, and are currently considered an emerging problem [1,2]. Peri-implant mucositis is defined as a reversible inflammatory reaction of the soft tissues that surround the implant in function, whereas the peri-implantitis is an inflammatory reaction associated with loss of bone support around the implant in function [4]. The key parameter for the diagnosis of periimplant mucositis is the presence of bleeding on probing [6,7]. For the diagnosis of peri-implantitis, in addition to bleeding on probing, it is necessary to combine it with an increase in probing depth associated with bone loss around implants [6,7,8,9,10]
