AB  - OBJECTIVE: To explore the reinforcement of polyglycidyl methacrylate (PGMA) 
      pre-impregnated quartz fiber mesh in denture base materials by investigation of 
      interface compatibility and fracture resistance. METHODS: 1-layer, 2-layer, 
      3-layer PGMA pre-impregnated quartz fiber meshes, electrolyzed cobalt-chromium 
      alloy mesh and cobalt-chromium alloy mesh conditioned by metal primer were 
      integrated in polymethyl methacrylate (PMMA) resin by sandwich embedding method. 
      Block samples of 5 groups were prepared (40 mmx15 mmx2 mm). Fracture resistance 
      was determined in a 3-point bending test at 2 mm/min. Scanning electron 
      microscope (SEM), micrographs were taken from the fractured surfaces to analyze 
      the bonding interface compatibility. RESULTS: The group of 3-layer PGMA 
      pre-impregnated quartz fiber mesh presented the highest elastic modulus of 6 406 
      MPa and flexural strength of 227 MPa among the five groups, while the 1-layer and 
      2-layer expressed the similar elastic modulus and flexural strength to the pure 
      PMMA group. The metal groups demonstrated better mechanical properties, while the 
      metal surface conditioner played much better. The metal surface conditioner 
      pre-impregnated cobalt-chromium alloy and PGMA pre-impregnated quartz fiber mesh 
      showed compatible interface with PMMA. CONCLUSION: The mechanical properties were 
      improved by the increasing of the fiber by adding the more meshed. Although the 
      benign interface did help the compatibility, the quantity of the fibers played an 
      important role in the strength.
