Abstract

Adoption of CAD/CAM milling in dentistry has allowed production of more analytic and precise prosthesis. Such precision enables definite path of insertion and undercut to be provided in removable partial denture especially when designing a surveyed crown on an abutment tooth. This case is about the production of surveyed crown with proper path of insertion utilizing CAD/CAM electronic surveying method on a patient with edentulous maxilla. Resulting removable partial denture fit well and showed acceptable stability and retention with no clinical problem.

컴퓨터를 이용한 CAD/CAM milling 방식이 치과 분야에도 적용됨에 따라 보다 분석적이고 정밀한 보철물이 제작 가능하게 되었다. 특히, 국소의치의 지대치로 사용되는 서베이드 크라운을 제작하는데 있어 이러한 디지털 방식의 정밀함은 국소의치의 삽입철거로와 언더컷 등이 정확하게 부여될 수 있게 한다. 본 증례는 상악의 다수 치아 상실을 보이는 환자에서 CAD/CAM을 이용하여 전자 서베잉을 통해 적절한 삽입철거로를 부여하고 지르코니아 서베이드 크라운을 제작하였다. 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다.
