title: [Three-dimensional digital dental model based on micro-CT].
abstract: OBJECTIVE
  To establish a three-dimensional digital dental model through scanning dental impression directly with micro-CT.
  
  
  METHODS
  The polyvinyl siloxane (PVS) impression of the plaster model was taken and scanned with micro-CT. VGStudio MAX and Imageware softwares were used to obtain the digital dental model.
  
  
  RESULTS
  The three-dimensional digital model was established successfully. The scanning layer was 90 µm.
  
  
  CONCLUSIONS
  A new way of establishing the digital dental models could be achieved with micro-CT.
