Abstract

Interim immediate denture is fabricated to minimize the period of edentulousness after removal of the patient's remaining teeth and before delivery of final prosthesis. In the case of using the CAD/CAM system, there is an advantage in that the manufacturing process in the clinic and laboratory can be simplified by overcoming some of the limitations of manufacturing interim immediate dentures in the traditional way. However, there are also disadvantages in that errors occur in the process of transmitting information about the patient's intermaxillary relationship to the digital network of the laboratory, resulting in unstable occlusal relationships or non-esthetic prostheses. To overcome this problem, using the simple and accurate POP BOW system's occlusal plane digital transfer method, it was possible to fabricate an esthetic and functional 3D printed interim immediate denture after removal of the remaining upper and lower anterior teeth.

모든 잔존치의 발거를 계획한 환자의 경우 최종 보철 제작 전 무치악으로 지내는 기간을 최소화하기 위해 미리 임시 즉시 의치를 제작하게 된다. CAD/CAM 시스템을 이용하면 전통적 방식에서의 한계점들을 보완하여 진료실과 기공실에서의 제작 과정을 간소화 시킬 수 있다는 장점이 있다. 하지만, 환자의 악간관계에 관한 정보를 정확하게 기공실의 디지털 네트워크로 전달하는 과정에서 오차가 발생하여 교합관계가 불안정하거나 비심미적인 보철물이 제작될 빈도가 높다는 단점도 있다. 이러한 문제점을 극복하기 위해 간단하고 정확한 POP BOW 시스템의 교합평면 디지털 전이법을 이용하여, 상하악 전치부 잔존치 발거 후 심미적이고 기능적인 3D 프린팅 임시 즉시의치를 장착한 환자의 성공적인 증례를 보고하고자 한다.
