Abstract
Design
This was a randomised cross-over study.
Intervention
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.
Outcome measure
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.
Results
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).
Conclusions
The findings of this study suggest that the participants significantly preferred posterior occlusal schemes with anatomic and lingualised teeth, compared with cuspless teeth.
