초록
본 증례 보고는 하악 전치에 발생한 치은 퇴축을 laterally closed tunnel technique을 이용하여 처치하였다. 환자는 모두 과거 교정 치료 시 하악 전치의 경사도를 변화시켰으며 치주 적으로 얇은 생체형을 가지고 있었다. 터널링법으로 수여 부를 형성하고 구개 측에서 채득한 결합조직이식편을 터널내에 위치시킨 후 판막의 변연을 치근 중앙부를 향해 측방으로 이동시켜 봉합하여 이식편을 피개 하였다. 얇은 치주 생체형에도 불구하고 치근 피개를 성공적으로 얻을 수 있었으며 각화 치은의 획득과 주변 조직과의 색, 형태 조화로 심미성을 달성할 수 있었다.
Abstract
In this case report, gingival recession of the mandibular anterior teeth was treated with a laterally closed tunnel technique. Two patients had altered the inclination of mandibular anterior tooth during past orthodontic treatment and had periodontal thin biotype. The recipient site was formed by tunneling method, and the connective tissue graft obtained from the palatal side was placed in the tunnel, and the margins of flap were gathered at the center of the root and sutured. Despite the thin periodontal biotype, the root coverage was successfully obtained, keratinized gingiva was increased, and aesthetics were achieved by harmonizing with surrounding tissues in terms of shape and color.
