초록
파절의 종류는 치관파절 치근파절, 동시에 나타난 치관-치근파절이 있고 치수노출에 따라 단순파절과 복잡파절로 나뉜다. 치아파절이 치은 연하로 침범하여 치아장축을 따라 나타난 경우나 치근의 1/3 이상을 넘어선 경우 발치가 원칙이다. 그러나 치근쪽 파절편을 교정적으로 정출시켜서 수복시켜 주는 방법과 인위적으로 발치하여 적절하게 수복 가능한 위치로 재식 시켜주는 방법을 선택적으로 이용할 수 있다. 본 증례에선 치아외상으로 상악 중절치가 치관-치근 파절된 혼합치열기의 환아에서 의도적 재식술을 이용하여 발치 후 즉일 근관치료와 역충전 후 레진수복을 시행하여 치료하였기에 보고하는 바이다.
Trauma to the tooth is the most common accidents in pediatric dentistry and tooth fracture occurs frequently. Fracture is classified into crown fracture, root fracture, and crown-root fracture which involves both. Also, it is classified into simple or complicated fracture depending on whether the pulp is exposed or not. When the fracture is extended down to the subgingival level following the long axis of the root, or when more than 1/3 of the root is involved, extraction is the primary treatment. But alternative treatment such as extruding the root fragment with orthodontic force and restoring it, or intentionally extracting the tooth and replanting it to a position which it can be restored. This is a case report on intentional replantation of a traumatized maxillary central incisor with crown-root fracture of a patient with mixed dentition. The teeth was extracted and immediate endodontic treatment, retrograde filling and resin restoration were carried out.
