What are the phases of empress crown application?
First of all, face and intraoral photographs of the patient are archived. Teeth sizes are measured and a smile design eligible for the patient is created. Then, the post-treatment appearance is demonstrated using a method which is called “mock up”. By this way, the smile design reaches its final shape by the dentist’s taking patient expectations into consideration.

In order to put the approved design into practice, teeth are corroded about 2 mm under local anesthesia and after the last measurement, acquired data is sent to the laboratory. Within the same session, temporary restorations are prepared in tooth color with the help of “mock up” and attached to teeth. Thus, the risk of tooth sensitivity is eliminated and the patient keeps his social life.
