Abstract

Purpose: Heat cure methyl methacrylate has been the denture base material of choice for the fabrication of conventional complete dentures and transitional removable partial dentures. One of the factors that cause fracture is considered to be low resistance to impact, flexural or fatigue. However, dentures repaired with auto-polymerizing acrylic resin alone often experience a re-fracture at the repaired site. This study aimed to evaluate flexural strength of heat polymerized acrylic resin repaired with different reinforcing materials.

Methods: 48 samples were prepared and divided into four groups. 12 samples were considered as controls, and 36 were divided into 3 experimental groups. The samples were sectioned into two halves from the middle, and were then repaired with rapid repair material, and reinforcing material. Each group was divided into 4 subgroups: unreinforced, reinforced with metal wire, metal mesh, and glass fiber. All specimens were subjected to a 3-point bending test, and the flexural strength was calculated. Results: all the reinforcement groups namely Stainless steel wire, metal mesh and glass fiber improves flexural strength of heat cured acrylic resin samples and glass fiber reinforced samples had the greatest flexural strength when compared with all other groups.
