title: The effect of esthetic fibers on the flow properties of an acrylic resin denture base material.
abstract: OBJECTIVE
  This study was conducted to measure the effect of viscose rayon esthetic fibers on the flow properties of an acrylic resin denture base material.
  
  
  METHODS
  Two testing methods using a needle penetrometer and an oscillating rheometer were employed on weighed proportions (0.1%, 0.2%, 0.8%, and 0.3%) of fiber.
  
  
  RESULTS
  The results show that the fibers affect the flow properties of the polymer/monomer mix. Increasing the percentage of fibers decreases the flow of the material and reduces the doughing time. With increasing amounts of fiber, a rapid increase in the viscosity occurs with a corresponding adverse effect on flow properties.
  
  
  CONCLUSIONS
  It is concluded that these properties are important for the successful handling of acrylic materials since they can influence the accuracy and quality of the molded denture.
