초록
임플란트 치료의 유지단계에서 임플란트 주변 연조직의 문제 중 하나는 부착조직의 부족한 범위이다. 각화조직은 치아 및 임플란트 주변에서 구강 위생의 유지 및 개선에 있어서 중요한 역할을 한다. 유리 치은 이식술은연조직 부족을 해결하고 임플란트 보철의 장기간의 예후를 증가시키기 위해 최적의 임플란트 주변 건강을 제공한다. 그러나 유리 치은 이식술 치료를 받은 환자들은 구개와 같은 공여부 상의 통증 및 불편감을 호소한다. 뿐만 아니라 술자에게 있어 기술적인 난이도를 요구하며, 시간이 오래걸리고 이상적인 형태와 비교하였을 때 종종 조직의 색깔 차이가 발생하는 등의 단점이 있다. 근단변위판막술은 임플란트 2차 수술과 동반하여 또는 이후에 간단히 부착 조직을 증대시키기 위해 선택된다. 이번 증례보고에서는 유리치은이식술을 대신하여 작은 범위의 임플란트 부위에서 근단변위판막술을 통한임플란트 주변 각화 조직의 폭경이 성공적으로 증가했음을 보이고자 한다.
Abstract
The one of peri-implant soft tissue problems seen during the maintenance phase of implant therapy is an inadequate zone of keratinized tissue. Keratinized tissue plays a major role around teeth and dental implants, helping in maintaining and facilitating oral hygiene. A free gingival graft (FGG) is chosen to correct the soft tissue defects and provide optimal peri-implant health in order to increase the long-term prognosis of the implant reconstruction. However, the patient treated with FGG has pain and discomfort on donor site such as palate. It is also technically demanding, time consuming,and the color match of the tissue is often less than ideal. An apically positioned flap (APF) is selected for increasing the keratinized tissue simply while or after the second stage implant surgery. This case report shows successfully increasing the width of peri-implant kenratinized tissue through APF procedure on small site of dental implant instead of FGG.
