Edentulous people prefer lingualised or anatomic posterior occlusal tooth forms

Abstract

This was a randomised cross-over study. Participants were randomly assigned to receive one of three sets of complete dentures with different types of posterior occlusal design forms, either anatomic teeth, lingualised teeth, and zero-degree teeth. The primary outcome measure was a visual analogue scale (VAS) focusing on five aspects of denture satisfaction. Data were recorded at baseline, considering their original dentures, and 8 weeks post-final review. The chewing function of the complete dentures provided with lingualised and anatomic posterior occlusal forms was preferred, statistically significantly, over that of zero-degree posterior occlusal forms (P 0.004 and P 0.001, respectively). The findings of this study suggest that the participants significantly preferred posterior occlusal schemes with anatomic and lingualised teeth, compared with cuspless teeth.
