Flexural strength of heat polymerized acrylic resin repaired with different reinforcing materials

Purpose: Heat cure methyl methacrylate has been the denture base material of choice for fabrication conventional complete dentures and transitional removable partial dentures. One factors that cause fracture is considered to be low resistance impact, flexural or fatigue. However, repaired with auto-polymerizing acrylic resin alone often experience a re-fracture at site. This study aimed evaluate strength heat polymerized different reinforcing materials.
 Methods: 48 samples were prepared divided into four groups. 12 as controls, 36 3 experimental The sectioned two halves from middle, then rapid repair material, material. Each group was 4 subgroups: unreinforced, reinforced metal wire, mesh, glass fiber. All specimens subjected 3-point bending test, calculated. Results: all reinforcement groups namely Stainless steel mesh fiber improves cured had greatest when compared other
