Background:
Despite long-term success of implant therapy, biological and technical complications do occur with time. Among biological complications, the peri-implant infection is a common clinical finding during follow-up periods. The prevalence of peri-implant mucositis and peri-implantitis ranged from 19 to 65% and from 1 to 47%, respectively. Various treatment modalities have been proposed for the treatment of peri-implantitis, and they were divided into 2 categories, i.e., non-surgical and surgical approaches. However, non-surgical approach for the peri-implantitis did not appear to be predictable and beneficial clinical outcomes seemed to be limited to a short period. Hence, surgical approaches became a mainstream of peri-implantitis treatment. In contrast to the resective surgical therapy aiming to eliminate infection around the implant, regenerative surgical therapy of peri-implantitis could successfully achieve a varying degree of re-osseointegration at the peri-implant bony defect.
Aim/Hypothesis:
This case report was carried out to evaluate the clinical outcome of surgical regenerative therapy of peri-implantitis with a combination of bone materials and bio-resorbable membrane
Material and Methods:
Two patients who had severe bony destruction around implants were treated with guided bone regeneration using bio-resorbable collagen membrane (Bio-Gide®), autogenous bone and xenograft (Bio-Oss®). At surgery, autogenous bone graft was obtained from the inferior border of the mandible with the use of a trephine, and particulated with a bone mill. Implant surfaces were decontaminated by using calcium phosphate and air powder abrasive treatment. Bony defect around the implant was filled with a combination of particulated autogenous bone and xenograft (Bio-Oss®) and covered with a bio-resorbable collagen membrane (Bio-Gide®). To evaluate the results of surgical regenerative therapy, pre- and post-surgical clinical examination, clinical photographs and standard radiographs were compared.
Results:
Healing was unevenful without any surgical complications. Pockets more than 4mm and bleeding on probing around implants were not found at the follow-up examination. Radiographic examination showed a varying degree of bone fill and increased radiopacity at the peri-implant bony defects.
Conclusions and clinical implications:
Although a complete fill of the peri-implant bony defect does not seem to be a predictable outcome, the regenerative surgical approaches appear to be encouraging for the treatment of peri-implantitis.
