Abstract

In patients with fully edentulous jaw, treatment of complete dentures should be carried out in many stages when following the conventional methods. Therefore there were disadvantages such as multiple visits to dental clinic is inevitable. In addition, errors caused by polymerization shrinkage, which happens during the fabrication of denture, and difficulties in reproduction of damaged or lost denture were considered as disadvantages. But nowadays, computer-aided design and computer-aided manufacturing (CAD/CAM) system is widely used in dentistry and it has begun to expand its spectrum in manufacturing complete dentures. Using CAD/CAM system to fabricate complete dentures can reduce the number of patient's visit and clinical chair time, since taking impression, recording jaw relation, and selection of artificial teeth are performed at the same time during the first visit, and delivering of dentures during the second visit is possible. In addition, because 3D-Printing technology is used, errors by polymerization shrinkage can be reduced. Among the companies that fabricate complete dentures using CAD/CAM system, DENTCA CAD/CAM denture (DENTCA Inc., Los Angeles, CA, USA) is the most commercialized company. In this case, we treated patients of complete dentures using conventional complete denture method and DENTCA CAD/CAM denture system in the same patient. We would like to report this case because we have achieved good results not only in functional aspects of pronunciation, chewing, and swallowing but also in aesthetic aspects.

무치악 환자에게서 의치의 제작은 통상적이고 전통적인 방법을 따를 경우 최종 의치 장착까지 여러 단계를 거쳐야 하며 이로 인한 환자의 잦은 내원이 불가피하다. 또한 기공 과정 상에서 나타나는 중합수축에 의한 오차나, 의치의 파절이나 분실 시 빠른 재제작의 어려움 등의 단점이 존재하였다. 하지만 최근 치과 분야에서 computer-aided design and computer-aided manufacturing (CAD/CAM) System이 사용되기 시작하였고, 의치 제작에까지 그 영역을 넓히기 시작하였다. CAD/CAM System을 이용하여 의치를 제작하면 첫 번째 내원 시에 인상채득과 악간관계의 기록, 인공치의 선택 등이 동시에 이루어지고 두 번째 내원 시 의치의 장착이 가능하기 때문에 환자의 내원 횟수와 진료시간을 감소시킬 수 있다. 또한 3D-Printing 기술을 이용하기 때문에 중합수축에 의한 기공 오차를 감소시킬 수 있다. 현재 상용화 되어 있는 CAD/CAM System을 사용한 의치로는 DENTCA CAD/CAM denture (DENTCA Inc., Los Angeles, CA, USA)가 있다. 본 증례에서는 상, 하악 완전 무치악 환자에게서 conventional 한 방법과 DENTCA CAD/CAM Denture System을 사용하는 방법을 동시에 사용하여 두 쌍의 총의치로 수복함으로써 발음, 저작, 연하 등의 기능적인 측면뿐만 아니라 심미적인 측면에서도 양호한 결과를 얻었기에 이를 보고하고자 한다.
