Abstract

The patient who has severely absorbed residual ridges, treatments are challenging to satisfy many factors: support, retention, stability, etc. The neutral zone or monoplane occlusion with non-anatomical tooth would be helpful to get additional retention and stability. The monoplane occlusion has been used long time because it can eliminate horizontal forces and many other advantages. The lingualized occlusion was introduced to improve chewing efficiency and esthetics. But from a stability aspect, it seems controversy between monoplane occlusion and lingualized occlusion. This case report shows the results of the treat two flat residual ridge patients using functional impression; piezography, and made 2 other dentures with monoplane and lingualized occlusion that patient can select denture.

치조골 흡수가 심한 무치악 환자에서는 지지의 부족으로 유지, 안정 등의 요인을 갖추기 어렵다. 이에 추가적인 유지와 안정의 획득을 위한 노력으로 중립대의 이용 또는 단일평면교합 형성이 있다. 단일평면교합은 수평력의 제거 등 장점이 있어 오랜기간 이용되었다. 그리고 여기에 저작 효율과 심미성을 개선시키기 위해 설측교두교합이 제시되었다. 하지만 안정성 면에서는 단일평면교합과 설측교두교합 사이에 여전히 논란이 있다. 본 증례는 하악 치조골의 과도한 흡수에 의해 편평한 치조제를 보이는 두 환자로, piezography를 이용하여 기능 인상을 채득하고 단일평면교합과 설측교두교합의 의치를 각각 제작함으로써 환자에게 의치를 비교 선택할 수 있도록 하여 환자의 만족도를 높였기에 이를 보고하는 바이다.
