초록

치은연 하방에 치아 우식증이나 치아 파절이 발생했을 때, 치아를 탈구시켜 즉시 정출시키는 외과적 정출술을 이용한 치관 연장술은 자연치를 보존하고 추가적인 치주적 수술 없이 단기간에 심미적인 보철 치료를 가능하게 한다. 본 환자는 16세 남환으로 본원 보존과로부터 상악 좌측 중절치의 심미 수복을 위해 본원 보철과로 의뢰되었다. 상악 좌측 중절치는 근관치료가 되어 있었으며 치관-치근 파절로 인해 협측 치관 길이는 4mm였으며 구개측 판막을 열었을 때 근심 구개측 치경부 파절 범위는 치은 하방 3-4mm에 위치하였다. 외과적 정출술을 통한 치관연장술을 시행하였으며 경과 관찰 및 임시 치아의 단계를 거쳐 3개월 후에 전부 도재관으로 수복하여 만족할 만한 임상결과를 얻을 수 있었다.

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3-4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result.
