The importance of the palate geometric shapes in the adaptation of upper complete dentures

Abstract

The authors analysed the influence of the palate geometric shapes (deep, intermediate and flat) in the adaptation of thermic- cured acrylic resin base in upper complete dentures. The maladjust- ments between acrylic resin base and stone cast were measured from the cuts of the anterior, medium and posterior (post dam) regions of the palate, with the aid of a linear microscope. The results, analysed through the Tukey´s test (p< 0,05), showed that the major maladjustments occurred in pos- terior region of the palatal area, not being influenced by the palate geometric shapes. Key words: complete denture; dental materials; acrylic resin.
