Abstract

The functionally generated path (FGP) technique, first described by Meyer in 1933, is a method in the oral cavity to use the movement pathway formed by the opposing cusps within the border movement of the mandible. Using this method, an appropriate occlusal shape can be given to the patient. In this case, the FGP technique was selected to provide a bilateral balanced occlusion when restoring the edentulous maxilla that opposes the natural mandibular teeth with irregular arrangement with overdentures. In addition, in order to precisely form the occlusal surface of the posterior region with the FGP technique and to reduce the attrition of denture teeth, zirconia denture teeth, not conventional resin artificial teeth, were individually manufactured. After treatment with these materials and methods, satisfactory results were obtained for both the operator and the patient.

1933년 Meyer에 의해 처음 기술된 Functionally generated path (FGP) technique은 하악의 한계운동 내에서 대합치 교두에 의해 형성된 운동 경로를 구강 내에서 인기하는 방법이다. 이 방법을 이용하여 환자에게 적절한 교합 형태를 부여할 수 있는데 이 증례에서는 자연치열과 대합되는 상악 피개의치를 제작하여 균형 교합을 부여하였다. 또한 FGP technique으로 구치부 교합면을 정밀하게 형성하고 의치 치아의 마모를 감소시키기 위해 통상적으로 사용하는 기성 레진 인공치가 아닌 지르코니아 의치 치아를 개별 제작하였다. 이러한 재료와 방법으로 치료 후 술자와 환자 모두 만족스러운 결과를 얻었기에 본 증례를 보고하는 바이다.
