STRESS ANALYSIS OF MAXILLARY DENTURE WITH REINFORCEMENT COMPOSITES IN TEMPERATURE CHANGE

The loss of teeth impairs patients’ like appearance, masticatory and speech etc. These functional disorders effect the quality of patients’ life standards. To restore these functions, removable partial or complete dentures are often used. In this study, the finite element method was used for carrying out stress analysis on midline of maxillary denture. Temperature of 0 °C, 36 °C, 70 °C and the suitable boundary conditions were applied to specimens reinforced with CrCo, UD/woven carbon epoxy, UD/woven glass epoxy, UD/woven kevlar epoxy. The results obtained show that these reinforcements used to increase the strength of the prosthesis have high thermal stresses under thermal loading compared to unreinforced specimens
