When you have consulted with your dentist
and decided to have a Cerec Crown placed, here's what you can expect when the procedure actually begins. First your dentist will have to examine your mouth to determine how much healthy tooth structure remains in your mouth, so he/she can be sure a crown will work in your circumstances. Assuming that your dentist considers a Cerec Crown appropriate for the situation, he/she will review options with you, and if you decide to go ahead with the Cerec Crown, the process will begin by preparing the damaged tooth and administering a local anesthetic.
If any decay has to be removed, this will be performed by the dentist. Then the whole area will be dried out in preparation for what follows. Next, it will be necessary to obtain a digital impression of your tooth, using an intraoral camera attached to a computer. You'll have to open your mouth wide in order for this to be effective, and the software in the computer will sketch out digital images of the surface of your tooth.
Using a number of different static pictures of the tooth, the computer will merge the images together in order to create a single 3D model of the affected tooth. The next step involves creating a customized dental crown for the tooth. In order to ensure that the new tooth looks similar to the other teeth in your mouth, the dentist will choose a Ceramic or Zirconia block
which is colored very similarly to your tooth's original color.
At this point, it will be possible to begin making the crown, and this milling phase will only require about 60 minutes. Once the crown is ready, it has to be comfortably fit into your mouth. Your dentist will ensure that you have the appropriate bite and the right fit before polishing and cementing the crown to your tooth. This will bind the tooth in place, so that you can begin using it for all normal activities.
