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.
