Patient evaluation of treatment success as related to denture tooth type.

PURPOSE: Tooth selection is considered an important factor in the construction of complete dentures that function harmoniously and comfortably and preserve the denture-supporting tissues. To bring a scientific background to clinical impressions, the hypothesis that different cusp angles bring different levels of patient satisfaction was tested. MATERIALS AND METHODS: Four different occlusal schemes were compared. The dependent variables (3 groups of visual analogue scores of patient satisfaction) were analyzed by means of multivariate analysis of variance (MANOVA) for repeated measures. RESULTS: All MANOVAs showed nonsignificant results for the effect of tooth type on the 3 groups of variables (P values between 0.1 and 0.8). CONCLUSION: The results did not show statistically significant differences in patient satisfaction among the different occlusal schemes. It is recommended that future research use more sensitive instruments to evaluate this specific aspect of treatment success.
