title: [Wear resistance of tooth hard tissue opposing dental alloy material in an adjustable wear simulator].
abstract: OBJECTIVE
  To evaluate wear resistance of human enamel by a customized adjustable wear simulator.
  
  
  METHODS
  Enamel specimens were prepared as experiment one which were divided into group A and B. The specimens were wear against soft Co-Cr alloy styli. Vertical loss were tested. The data was analyzed statistically by paired sample t test using SAS14.0 software package.
  
  
  RESULTS
  The vertical substance loss of two groups were not significantly different (P=0.7464).
  
  
  CONCLUSIONS
  The adjustable wear simulator works well. The coefficient of the wear test is adjustable, and the result is reliable. The simulator can be used in wear test of tooth and dental material.
