Complete dentures can be produced with different types of occlusal forms. There is some evidence to suggest that it may be advantageous to provide complete dentures with cusped posterior teeth. The aim of this research was to compare the levels of subject satisfaction with 3 types of posterior occlusal forms for complete dentures, in a randomized cross-over trial design. Forty-five participants were randomly assigned 3 sets of complete dentures with different posterior occlusal forms (zero-degree, anatomic, and lingualized occlusions). Subjective data were collected according to visual analogue scales after 8 weeks of denture-wearing. Statistical analysis consisted of repeated-measures analysis of variance, followed by paired t tests. Lingualized and anatomic occlusal forms were perceived to be significantly superior in terms of chewing ability, when compared with zero-degree posterior occlusal surfaces.
