The aim of this study was to evaluate the relationship between the denture material, masticatory performance, and patient satisfaction.

In the study, five patients with completely or partially edentulous arches were included. The copy denture technique was applicated in making the dentures, and divided them into a pure titanium group, a PMMA group and a cobalt-chormium group. Then their masticatory efficiency was measured by chewing peanuts. The patients′ satisfaction were compared among the three groups when they were first wearing the dentures.

The pure titanium and the cobalt-chormium group performed better in masticatory efficiency than the PMMA group (P < 0.05) , but there was no statistically significant difference between the pure titanium and the cobalt-chormium group (t= 0.137, P= 0.898) . There was higher patient overall satisfaction level when the patients wore the pure titanium base dentures.

Although there were statistically significant correlations found between denture material, masticatory performance, and patient satisfaction, the masticatory function was not totally affected by the denture base materials, and the patient satisfaction was not strongly related to the masticatory efficiency of the prosthesis.
