Laboratory Evaluation of Newly Formulated Thermoplastic Resin Complete Denture Base Materials

Abstract

Aim of the work: To investigate the physic-mechanical properties of newly formulated thermoplastic denture base material. Materials and Methods: Two parallel groups according to the denture base material used Group (A) conventional heat cure acrylic resin i .e. control group, Group (B)Vertex thermosens i.e. test group, 35 specimens each (14 impact, 14 flexural and 7warpage)will be examined in this study. Each group will be divided into 2 subgroups: (I) No Thermocycling and (II) Thermocycling then subjected to 3 different tests, Impact strength, flexural strength and warpage. Results and Conclusions: 1.The vertex thermosens denture base material exhibited significantly higher impact and flexural strength as compared with conventional PMMA.2.There was significant increase in impact strength of vertex thermosens and non statistically significant of flexural strength of both groups after thermocycling.3.Warpage of vertex thermosens was statistically significant higher than conventional PMMA.4.There was a significant increase of warpage after thermocycling for both groups.
