환자의 교합에 맞춰 적절한 고정성 보철물을 성공적으로 제작 및 수복하기 위해서 필요한 다양한 고려사항이 있다. 그 중 환자가 갖고 있는 교합의 형태를 파악하여 고정성 보철물에 부여하는 것은 필수적이라 할 수 있다. 견치 유도 교합, 군 기능 교합 등 여러가지 교합 형태를 파악하는데 있어서 하악의 운동을 기록하는 것이 중요한데, 1933년 Meyers에 의해 소개된 Functionally generated path (FGP) technique은 구내에서 왁스 등의 재료를 이용하여 교두가 지나가는 하악 운동로를 기록한 후 보철물 제작에 적용하는 치료 술식이다. 본 증례에서는 두 명의 환자에 있어서 상악 구치부에 이차 우식 혹은 치주염으로부터 기원한 치수 유래 병소가 있어, 근관 치료 및 치주 치료 완료 후 고정성 보철물 수복이 필요하였다. 장기적인 예후가 좋지 않은 치아이기에 측방 간섭을 최소화하기 위해 FGP technique을 이용하여 하악 운동을 기록하였다. 통상적인 석고 인상 방법이 아닌 구내 디지털 스캔을 시행함으로써 더 효율적으로 보철물을 제작하였다. 치료 후 환자와 술자 모두 기능적으로 만족할 만한 결과를 얻었기에 이를 보고하는 바이다.
Abstract
In order to deliver fixed partial denture to a patient successfully, dentist must take into many considerations beforehand. Patient’s occlusal pattern should be fully understood before delivering any type of prosthesis, whether it’s canine guidance or group function occlusion. In order to do so, movement of mandible should be recorded precisely. Introduced by Meyers in 1933, functionally generated path technique (FGP) has been successfully used to record mandibular movement with various materials, such as wax, and utilize it in fabricating precise prosthesis. In the following cases, patients showed secondary caries or endodontic-periodontic lesion on maxillary molars. Root canal treatment and subgingival curettage were done for each patient. Since the long term prognosis of each tooth was questionable, lateral force should be minimized. In order to do so, FGP technique was used to record mandibular movements precisely. Instead of using conventional plaster impression, intra-oral scanning of wax tracing was done to fabricate prosthesis efficiently. After delivery of fixed partial denture, favorable outcome was obtained.
