Abstract

The present study evaluated the long-term outcome of a combined surgical and composite graft (bovine porous bone mineral BPBM and autogenous bone) in the treatment of peri-implantitis. Six individuals with titanium implants demonstrating a marginal bone loss. Baseline ,1 and 6 years measurements, including introral digital radiographs, gingival index (GI), probing depth(PD) and probing bone level (BL) were performed. In each implant subgingival bacterial samples were obtained and subjected to microbiological analysis by culture. Surgical exposure of the lesions and cleaning of the implants using hydrogen perioxide and2% aqueous solution of chlorohexidine gluconate were performed. The autogenous bone was harvested from the chin combined with BPBM and packed into the bony defects. The treatment was evaluated clinically, microbiologically and radiographically at 1 and 6 years. Results: revealed a significant reduction in plaque and gingival bleeding. The mean probing depth was 6.94+ 1.16 at the baseline and it was 1.91 + 1.21 at the end of the study period. All treated implants showed bonegain. The mean gain in bone level was 5.12 + 0.5 and radiological evaluation of bone density was measured at crest, mid-implant and lateral apical area of interest AOI 32.0 + 0.87, 72.91 +0.83, 63.0 + 0.94 at baseline and it reached 109.5 + 0.53, 141.63 + 1.19 and 144.0 + 0.47 respectively. The presence of putative periodontal pathogens significantly declined at the end of the study period.
Conclusions:
The results of the study suggest that the use of composite bone grafts as the treatment strategy for peri-implantitis lesions with maintenance of good oral hygiene appears to be an

efficacious treatment approach for restoring year follow-up period.
