Comparison of flexural strength in two types of denture base resins
Keywords:
Denture, Base, ResinAbstract
Background: The present study was conducted for assessing and comparing flexural strength in two types of denture base resins. Materials & methods: A total of 20 acrylic specimens were made. Stainless steel dies were made. Twenty acrylic specimens were fabricated using these stainless steel dies. The metal dies were flasked using dental plaster to complete the flasking procedure. The stainless steel dies were retrieved to create the mold space for the acrylic specimen. All the specimens were randomly divided into to study groups as follows: Group A: Conventional denture base resins and Group B: Glass reinforced denture base resins. Flexural strength of the samples was accessed using the universal testing machine. Results: Mean flexural strength of group A specimens was 109.5 MPa. Mean flexural strength of group B specimens was 139.7 MPa. While comparing the mean flexural strength between group A and group B, significant results were obtained. Conclusion: Glass reinforced denture base resins demonstrated higher flexural strength in comparison to conventional denture base resin.
