TI  - Reinforcing Heat-cured Poly-methyl-methacrylate Resins using Fibers of Glass, 
      Polyaramid, and Nylon: An in vitro Study.
PG  - 948-952
AB  - INTRODUCTION: As civilization has progressed, there has been continued refinement 
      of materials available for dental practice. The applications of resins have been 
      extended to increased practical uses in numerous areas of prosthetic and 
      restorative dentistry. Certain significant alterations in the technique of 
      manipulation and nature of the dental product have influenced the range of 
      application in dentistry. The present study was done to measure and compare the 
      fracture strength of heat polymerized poly-methyl-methacrylate (PMMA) resin 
      reinforced with fibers of glass, polyaramid, and nylon. MATERIALS AND METHODS: 
      The present study was conducted in vitro on 40 PMMA denture base resin specimens. 
      Specimens were divided into four subgroups with ten specimens each and tested for 
      transverse strength using universal testing machine. RESULTS: In group I, the 
      transverse strength mean value was 67.82 MPa. In group II, the transverse 
      strength mean value was 59.47 MPa. In group III, the transverse strength mean 
      value was 66.87 MPa, while in group IV, the transverse strength mean value was 
      66.47 MPa. CONCLUSION: Incorporation of 4% weight glass fibers in loose form 
      significantly increased the transverse strength of denture base PMMA, while 4% of 
      polyaramid fiber in random distribution significantly increased the transverse 
      strength of denture base PMMA.
