초록
최근 삼차원적 안면 스캔 (facial scan) 및 악운동 (jaw motion) 등의 데이터를 통합하여 동적 교합을 나타내는 가상 환자를 형성함으로써 심미적인 전치부 고정성 보철물을 제작하는 방법이 소개되고 있다. 이를 통해 진단과정에서 환자와의 원활한 소통이 가능하며, 심미적인 보철 치료의 예지성을 높일 수 있고, 교합조정의 가능성을 낮출 수 있다. 본 증례에서는 상악 전치부 심미 보철 수복이 필요한 환자에서 구강 스캔 데이터와 삼차원 (3D) 안면 스캔 데이터, 환자의 악운동 기록을 computer-aided design (CAD) 소프트웨어 상에서 통합하여 동적 교합을 나타내는 가상 환자를 형성하였다. 이를 통해 치료의 결과를 시뮬레이션하고 심미적인 상악 전치부 고정성 보철물을 제작 및 수복하였다. 또한, 안정적인 교합관계를 회복하고 적절한 전방유도가 형성되었는지 확인하기 위하여 각각 치료 단계별로 환자의 교합을 비교 평가하였으며 심미적, 기능적으로 만족스러운 결과를 보였기에 이를 보고하는 바이다.
Abstract
Recently, a method of fabricating an esthetic anterior fixed prosthesis by integrating data such as three-dimensional facial scan and jaw motion to form a virtual patient with dynamic occlusion has been introduced. This enables smooth communication with patients during the diagnosis process, improves the predictability of esthetic prosthetic treatment, and lowers the possibility of occlusal adjustment. In this case report, a virtual patient with dynamic occlusion was created in which the results of the treatment were simulated, and esthetic maxillary anterior fixed prosthesis was fabricated. With the aid of the virtual patient, the final restorations were satisfactory both in terms of esthetic and function.
