현재 치과 임프란트는 부분 무치악 혹은 전악 무치악 환 자의 보철 수복에 있어 보편화된 치료 방법이 되었다. 이 미 많은 장기간의 연구들을 통해 임프란트는 높은 성공 율을 보여주고 있다.1) 하지만 치조골의 수평 혹은 수직적 흡수는 심미적이고 안전한 임프란트 식립을 어렵게 한 다. 특히 상악 전치부 임프란트 식립은 성공적인 골유착 을 필요로 할 뿐아니라 심미성이 가장 요구되는 시술이 기도하다.
Dental implant placement have been routine and common procedure for restoration of partial or complete edentulous patients. However, alveolar bone resorption caused by periodontitis, ,trauma or extraction compromises ideal implant placement on esthetic zone. Dehiscence or fenestration defect around implant on maxillary anterior can result in serious esthetic problem. Guided bone regeneration(GBR) procedure using barrier membrane have been recommended for augmentation of dehiscence or fenestration defect. In the present case, a 46 year old male patient visited at the department of periodontology, Yonsei University for implantation on maxillary anterior. Dehiscene and fenestration defect around implant was observed following placement of implant on maxillary anterior. Xenograft(BioOss®) graft and non-resorbable membrane were applied on exposed implant surface and buccal resorbed plate. And then primary soft tissue closure over the membrane was performed. At 4 months post-operatively, healing abutment was connected and regenerated bone on the buccal side of implant was observed. In conclusion, it is suggested that GBR procedure is a safe and reliable method for dehiscence or fenestration defect around implants.
