Abstract

It is essential to record maxillomandibular relationship accurately for the harmony of esthetic and function in complete denture. Gothic arch tracing visually demonstrates the movement of the mandible, and is useful to establish accurate and reproducible centric relation. Proper retention and stability of complete denture in patients with severe alveolar bone resorption is difficult to attain. In such case, the closed mouth impression technique might be recommended. The denture border and impression are determined by patient's physiologic movement in the closed mouth impression technique. And, denture peripheral border is entirely closed with oral mucous membrane. This report presents satisfactory complete denture restoration using closed mouth impression technique and gothic arch tracing in patients with mandibular condyle fracture and severe absorption of mandibular alveolar ridge.

심미와 기능이 조화를 이루는 총의치 제작을 위해서는 상하악 관계를 정확히 기록하는 것이 필수적이다. 고딕아치 묘기법은 하악의 운동을 시각적으로 보여주며, 정확하고 반복재현성 있는 중심위를 확립하는데 유용하다. 또한, 고도의 치조제 흡수를 갖는 환자에서는 총의치의 적절한 유지 및 안정을 얻기가 어려운데, 이런 경우 환자의 생리적인 동작으로 변연을 형성하여 의치상연 주위가 가동점막으로 봉쇄되도록 하는 폐구 인상법이 유용할 수 있다. 본 증례에서는 우측 하악과두골절 병력과 고도의 하악 치조제 흡수를 보이는 환자에서 폐구인상법과 고딕아치 묘기법을 이용한 총의치로 수복하였고 만족할 만한 결과를 얻어 보고하는 바이다.
