초록
구치부 지지소실과 편측 저작으로 교합이 환자는 불안정한 하악운동을 보이며, 이는 고령의 환자에서 복잡하게 나타날 수 있다. 본 증례에서는 교합붕괴와 이상 하악운동(Oral dyskinesia)을 보이는 환자에서 고딕아치 묘기법(Gothic arch tracing)과 스플릿 캐스트법(Split cast technique)을 이용하여 중심위와 습관적 전방 폐구위를 확인하고자 하였다. 이후 교합안정장치 형태의 임시의치를 사용하여 안정된 교합과 재현성 있는 하악운동을 회복하고자 하였고, 설측교합(Lingualized occlusion) 개념을 이용하여 총의치와 국소의치를 제작해 수복하였다.
Abstract
Patients with collapsed occlusal support and unilateral chewing show parafunctional mandibular movements, which can be complicated in older patients. Gothic arch tracing and split cast technique are used to confirm the deviation between centric relation and anterior habitual bite in patient who has oral dyskinesia and collapsed occlusion. Temporary denture as occlusal stabilization appliance was provided for stable occlusion and reproducible mandibular movement. Definitive denture was fabricated by lingualized occlusion concept.
