Abstract

In order to manufacture functional and esthetic prostheses, it is essential to accurately transmit information about the patient's occlusal plane. In particular, in the case of a completely edentulous patient, the occlusal plane is very important to correctly support the soft tissue, to achieve aesthetic harmony with the facial appearance, and to properly pronounce it, and to form a balanced occlusal relationship for stable mastication. In the conventional method, various facebow systems were used to transmit patient's information from the clinic to the laboratory, but there were several limitations in the process of transferring them to CAD. To simplify this process, a prefabricated POP (PNUD Occlusal Plane) Bow system was recently developed. In this case, a CAD-CAM (Computer-aided design-computer-aided manufacturing) treatment dentures reflecting the patient's occlusal plane information was manufactured using the POP Bow system during the treatment of a completely edentulous patient, and aesthetic and functional satisfaction was obtained.

기능적이고 심미적인 보철물을 제작하기 위해서 환자의 교합평면에 관한 정보를 정확하게 전달하는 과정은 필수적이다. 특히, 완전 무치악 환자의 경우 교합평면은 의치가 연조직을 올바르게 지지하고 안모와 심미적 조화를 이루며 제대로 된 발음을 할 수 있도록 중요한 기준을 제시하고, 안정적인 저작작용을 위한 균형 있는 교합관계를 형성하는데 매우 중요한 역할을 한다. 전통적으로 환자의 악간 관계와 교합평면에 대한 정보를 진료실에서 기공실로 전달하기 위해 교합기에 연결하여 사용하는 다양한 안궁(facebow) 시스템을 이용하였으나, CAD 상으로 이를 옮기는 과정에서는 여러 한계점이 있었다. 이 과정을 단순화하기 위하여 최근 조립식의 POP(PNUD Occlusal Plane) Bow system이 개발되었다. 본 증례에서는 완전 무치악 환자의 치료 과정에서 POP Bow system을 적용하여 환자의 교합평면 정보가 잘 반영된 CAD-CAM(Computer-aided design-computer-aided manufacturing) 치료 의치를 제작하였고, 심미적이고 기능적인 만족도를 얻을 수 있었다.
