title: [Effect of carbon ion implantation on the surface properties of denture base resins].
abstract: OBJECTIVE
  To investigate the effect of carbon ion implantation on the surface properties of denture base resins.
  
  
  METHODS
  Twenty heat-curing denture base resins specimens were made in this study. All the specimens were equally divided into two groups randomly with each group ten specimens. One was experimental group for carbon ion implantation and the other was control group without any treatment. The nano-hardness, wettability and wearability of all the specimens were tested. Then one specimen chosen from each group was used for infrared spectrum analysis.
  
  
  RESULTS
  There was statistical difference in nano-hardness, contact angle and quality loss between experimental group and control group (P < 0.01). New hydroxyl was formed in the surface of experimental group specimen from infrared spectrum analysis.
  
  
  CONCLUSIONS
  Carbon ion implantation has a positive effect in improving the surface properties of denture base resins.
