title: [The application of auro-galvano-form ceramic crowns in clinic].
abstract: OBJECTIVE
  To evaluate the effects of auro-galvano-form ceramic crown in clinic.
  
  
  METHODS
  The Ni-Cr alloy high-gold alloy and auro-galvano-form ceramic crowns were made respectively. Every kind was 200 pieces. 600 piece crowns were in total for 298 patients. The color of ceramic crowns was checked with Shade Eye. The color, fitness and fracture of ceramic crowns were checked in clinic.
  
  
  RESULTS
  The results showed the aurogalvano-form ceramic crowns was similar to high-gold alloy ceramic crowns in color and fitness in clinic (P > 0.05). The effects of them were better than Ni-Cr alloy ceramic crowns in color and fitness significantly (P < 0.05). The fracture of 600 ceramic crowns was not found out in two years.
  
  
  CONCLUSIONS
  The effects of auro-galvano-form ceramic crowns were perfect in color, fitness and fracture. It can be used in clinic.
