Abstract

Retromolar pad is one of anatomical landmarks to use clinically for determining of specific occlusal plane level in edentulous patients and is inherently a soft tissue mass; located at the distal end of mandible and should be covered with denture. The shapes of retromolar pad show variability because it might be inevitable to be resultant forms from healing and remodeling process after the extraction of last molars. Considerations would be focused on those resultant shapes and classification with anatomical relationships and clinical significances.

무치악 환자의 교합평면 수준을 결정할 때 후구치삼각융기는 흔하게 이용하는 해부학적 지표 중 하나로 연조직 덩어리이며 의치의 의해 피개 되어야 한다. 후구치삼각융기의 형태는 다양성을 보이며 이는 최후방 치아 발거에 따른 치유과정을 통해 형성되는 변화는 필연적이기 때문이다. 본 문헌고찰은 후구치삼각융기의 형태에 있어서 해부학적 관계와 임상적인 가치를 고려하고 형태적인 분류에 관해 고찰하고자 하였다.
