Abstract :

Background. Type of materials used in faication of denture base has an effect on dimension during denture base material processing and other factors related to clinical use. Objective. the study aims were to assess the dimensional stability including thermal changes of three different denture base materials. Methods. Ninety patients were selected to construct complete dentures with different denture base materials. They were randomly divided into three groups: Group 1, patients with cobalt chrome metallic base Group 2, patients with heat curing acrylic resin faicated by injection moulding technique Group 3, patients with denture bases faicated by conventional heat curing acrylic resin. The dimensional changes were assessed using digital caliper. Results. After the twelfth month, injection moulding acrylic resin had significantly the highest dimensional change followed by the conventional heat curing acrylic resin. There were no significant differences in the dimensions between the three types of denture base materials at normal mouth temperature, while, after hot tea drinking at 45∘C, the dimensional change was significantly the highest in cobalt chrome metallic denture base group. Conclusion. Cobalt chrome metallic denture base has stable dimension compared to denture bases faicated of acrylic resin but it was more affected by altered mouth temperature.
