Enamel imitates the incisive transparency of enamel.
It is applied on top of the dentine mass. When applying the Enamel for the first time, you should focus on the adjacent teeth and restore the necessary anatomy of the restoration by 10% more than the desired result.

  • 1st enamel treatment: After applying dentin, place the crown on the oven tray and place it in the oven at a preheating temperature of 450°C. Next, keep the oven closed for 6 minutes (the reaction starts at 450 ° C vacuum) and warm up to 810 ° C with a rise step of 45 ° C/minute. Exposure time: 1 minute in vacuum mode. For more than one prosthesis with a high porcelain content, the firing temperature can be increased by about 10°C.
  • After completing the firing of the first layer of Enamel, align and clean the crown or bridge. Next, to burn the second dentin, apply a second layer of Enamel or Dentin.
  • 2nd enamel treatment: Follow the same steps as during the first firing of the dentine, while the firing temperature must be reduced by 10 °C.
