Abstract

There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다.
