Treatment of peri-implantitis includes mechanical debridement, pharmaceutical therapy, and surgical procedures, often used in combination. In a lesion showing peri-implant bone loss of over 2 mm in defect depth and probing pocket depth of over 5 mm around the implant, surgical intervention may be considered. Among the available surgical treatments, regenerative therapy may be used for defects involving the bony walls surrounding the fixture, such as intrabony or circumferential defects. In the following case reports, xenografts with or without autogenous bone were used in conjunction with non-resorbable Ti-reinforced membrane (case 1) or with resorbable membrane (case 2) to treat peri-implant bone loss. Although it is not clear if re-osseointegration was established or if there exists merely bone fill within the previous defect area, anatomical correction to reduce plaque retention and improvements of clinical results were shown.
