Abstract
Purpose: The implant surface would be exposed during healing period by several causes as marginal bone resorption and inadequate drilling. Implant surface exposure can cause accumulation of plaque and microbials around implant and can develop peri-implantitis. Therefore, surgeon should be fully aware of adequate management of exposed surface of implant. This study aimed to evaluate the result of various treatment on exposed surface of implant.
Material and methods: A retrospective chart review and radiologic analysis were conducted of 25 fixtures among 14 patients(male 9, female 5) during period from June 2007 to January 2008. We evaluated implant survival rate, soft tissue index and marginal bone loss after functional loading.
Results: In second surgery, measurement of implant thread exposure was 3.04mm±2.97 on buccal, 0.36±0.9mm on lingual, 0.64±1.11mm mesial, 0.64±1.03mm distal in average. In 25 cases, bone graft was done on exposed area in 22 cases. Allograft mixed with alloplast was used in 3 cases. Xenograft was used in 11 cases. And alloplast was used in 8 cases. The cases showed 100% survival rate and functioned stably during follow-up period.
Conclusion: We suggest that implant with exposed surface can function successfully with adequate treatment.
