영구 전치의 복합 치관-치근 파절은 심미적, 기능적 문제 뿐 아니라 심리적 문제도 발생시킨다. 그러므로 파절에 대한 치료는 매우 중요하며, 여러 분야에 걸친 종합적 치료가 요구된다. 본 증례는 두 환자에서의 외상으로 인한 상악 전치의 복합 치관-치근 파절에 대한 임상적 치료 과정을 서술하였다. 근관치료와 근첨형성술이 각 환자에게 시행되었으며, 파절선을 치은 상방으로 노출시키고 생물학적 폭경을 재확립하기 위해 교정적 정출을 시행하였다. 이후 유지기간을 두었고, 그 기간 동안 치아에 임시수복을 시행하였다. 최종적으로 CAD/CAM을 이용한 세라믹 크라운 수복을 시행하였다. 이후 정기 검진 때에도 해당 치아들은 만족스러운 기능적, 심미적 결과를 보였으며, 두 환자 모두에서 재발은 나타나지 않았다. 치주조직 또한 건강한 상태를 보였다.

Complicated crown-root fracture of permanent incisors cause esthetic, functional, and psychological problems to patients. Therefore, treatment is important and multidisciplinary treatment is required. This case report describes the clinical procedures involved in the treatment of trauma-induced complicated crown-root fractures in the maxillary incisor of two young patients. Conventional root canal treatment and apexification were performed in each patient. To expose the fracture margins to the supragingival level and to reestablish the biologic width, orthodontic extrusions with fixed appliances were performed followed by a retention period. During the retention period, fiber-optic posts and cores were built up and provisional crowns were placed. Finally, ceramic crowns manufactured using a computer-aided design/computer-aided manufacturing (CAD/CAM) system were placed. In both patients, the teeth presented satisfactory functional and esthetic outcomes without relapse. The periodontal tissues were healthy.

문제 정의
This report describes the multidisciplinary treatment of complicated crown-root fractures in two young patients with favorable clinical results.
제안 방법
On the basis of clinical and radiographic findings, a diagnosis of complicated crown-root fracture was made. A definitive treatment plan was developed to include a root canal treatment and post-retained crown along with orthodontic extrusion to move the fracture line 3 mm above the alveolar crest.
On the basis of clinical and radiographic findings, a diagnosis of complicated crown-root fracture with concussion of maxillary left central incisor and enamel fracture of lower central incisors was made. For treatment, apexification with mineral trioxide aggregate (MTA) and a post-retained crown were planned.
The patient was evaluated on subsequent visits to monitor the restoration. The tooth presented satisfactory functional and esthetic outcomes and no relapse was noted.
The patient was kept on recall checks to monitor the restoration. Through periapical radiographs, formation of a hard tissue apical barrier was found (Fig.
