title: A two-stage surgical approach to the treatment of severe peri-implant defect: a 30-month clinical follow-up report.
abstract: With the advance of dental implant technology and the consequential increase in its success rate, the implant has become a highly predictable treatment method. Despite this, related complications are on the rise, with peri-implant mucositis and peri-implantitis being the most commonly observed. As in the case of conventional periodontitis, many patients experience peri-implant mucositis and peri-implantitis. In this case presentation, extensive bone loss occurred around the implant due to peri-implantitis, and the infection was first treated by applying chlorhexidine-soaked gauze and topical antibiotics. Then the guided bone regeneration procedure was performed using a bovine bone material and a collagen membrane, which resulted in the recovery of the lesion. With follow-ups of the healing process for 30 months, a successful outcome was observed that is reported herein.
