구강암에 대한 외과적 처치로 구강 내 광범위한 경조직, 연조직을 제거한 환자는 저작, 연하, 발음 등의 기능적 문제와 치열, 안모의 심미적 문제를 갖게 된다. 악골 재건 후에도 치조골 등 합병증으로 인해 가철성 보철물의 유지 및 지지를 받는데 제한적이다. 임플란트 지지 고정성 보철물은 이러한 환자들에게 적절한 보철수복 방법이 되어 왔다. 본 증례는 하악 재건 후 computer-aided design과 computer-aided manufacturing을 이용하여 지르코니아 프레임워크 상부에 단일 구조 지르코니아 크라운을 제작하여 현재 치열의 기능적, 심미적 회복을 하여 이에 보고하고자 한다.
Abstract
Defects due to mandibulectomy often cause hard and soft tissue loss and result in esthetic problems and functional disorders such as mastication, swallowing, and pronunciation. After the mandibular reconstruction, several complications including loss of alveolar bone can cause limitations in maintenance or supporting of removable prosthesis. For these patients, implant-supported fixed restorations have been an appropriate prosthetic restorative method. In this case report, we report the patient who underwent mandibulectomy and mandibular reconstruction owing to oral cancer, and then restored the current dentition functionally and aesthetically by applying zirconia frameworks and monolithic zirconia crowns by computer-aided design and computer-aided manufacturing.
