Abstract

Background:The purpose of the current investigation was to compare the flexural strength of denture base resins made through compression molding as well as injection molding. Materials & methods:20 denture base resin samples had been included as well as were separated into 2 study categories with 10 samples in every group: Compression molding category as well as injection molding category. Standardization was achieved during specimen fabrication with the help of metal strips. Standard methods of polishing as well as finishing were applied. After being polished, each sample was measured using a digital calliper to ensure consistency in size. There was some thermocycling action taken. A Universal Testing Machine equipped with specialized software was used to evaluate the flexural strength of the fracture resistance. Results: The average flexural strength of the injection-molded group was 79.35 MPa, compared to 67.23 MPa for the conventional molding group. When comparing the average flexural strength of samples from the two groups, significant differences were found. Conclusion:The flexural strength of denture base resin materials that have been treated using injection molding is superior to that of denture base resin materials produced via compression molding
