Recovery of masticatory function by posterior cross-bite denture in consideration for denture stability at occlusion

Abstract

For stability of the denture, controlling the occlusal force is essential. In certain cases such as mandibular protrusion, with normal arrangement of artificial teeth the denture is prone to overturn and often causes pain in the mucosa under the denture base and also other troubles including denture fracture. As deviation of mandibular position due to chewing habits and remaining teeth could root instability of denture in the long term, for the present case the artificial teeth were so arranged to resolve mandibular deviation at the time of occlusion. Recovery of masticatory function was confirmed by measurements of masticatory ability before and after the relevant intervention.
