Treatment of peri-implantitis and guided bone regeneration associated with autogenous bone: A case report

Abstract / Introduction: Dental implants have been considered important allies in the rehabilitation treatment of lost teeth, either in single-unit cases or in more complex rehabilitations. However, adverse outcomes may occur, for instance, peri-implantitis, which is an infectious disease similar to chronic periodontitis, afecting peri-implant tissues of which treatment aims at restoring health, as well as function and esthetics. Most treatments focus on reducing the microbiological burden of the peri-implant environment pocket by decontaminating the implant surface. In many cases, treatment of infection is followed by bone regeneration with fairly good results. Several treatment protocols have been suggested, however, little is yet known whether these therapies are able to lead to new osseointegration of implants. Objective: he aim of this case report was to show some aspects of peri-implantitis with emphasis on its treatment, and to show the outcomes of associating autogenous bone graft with guided bone regeneration. Our results reveal that the association between both techniques might result in high bone gain rates and complete implant cover.
