A biomechanical reinforcement of PMMA denture base material with sericin and fibroin: A preliminary screening study.

Background: Polymethyl methacrylate (PMMA) is a commonly used denture base material, but susceptibility to fracture under functional loading remains a challenge.

Objective: This preliminary screening study aims to investigate the potential of sericin and fibroin as reinforcing agents in the PMMA denture base material.

Methods: The flexural and impact strengths of PMMA incorporated with 0.
