Abstract

For patients with unstable mandibular movements and centric relation of the mandible due to long-term use of ill-fitting dentures, the successful fabrication of new dentures is challenging. Before fabrication new dentures, registration of centric relation is the critical point in such cases. In this case, treatment dentures with a flat occlusal table were used to stabilize mandibular movements and to register centric relation. In order to reflect the patient's jaw relation and vertical dimension obtained through the treatment dentures to the final denture, the treatment dentures were digitally duplicated, and impressions and jaw relations were obtained using the duplicated therapeutic dentures. The clinical results were satisfactory on the aspect of aesthetic and masticatory functioned.

잘 맞지 않는 의치를 장기간 사용하여 불안정한 하악운동을 가진 환자에게서 성공적인 새 의치를 제작하는 것은 도전적이다. 이러한 증례에서 새 의치를 제작하기 전에 정확한 중심위를 채득하는 것은 매우 중요하다. 본 증례에서 하악의 운동을 안정화 시키고, 중심위를 채득하기 위해 flat occlusal table을 가진 치료의치를 이용하였다. 치료의치를 통해 얻어진 환자의 악간관계와 수직고경을 최종의치에 최대한 반영하기 위해 치료의치를 디지털 복제하였고, 복제된 치료의치 이용하여 인상과 악간관계 채득하였다. 이를 통해 심미적, 기능적으로 만족할 만한 결과를 얻었기에 보고하는 바이다.
