Once the crown's fit has been verified, and any necessary aesthetic enhancements have been made to the crown's surface (staining and glazing, for example), the crown will be bonded to your tooth. The computer's digital design is transmitted to a milling machine that carves the crown from the ceramic block in about five minutes. Then a block of dental ceramic material is chosen in the shade that most closely matches your own teeth. The software can even be used to create a mirror-image twin of the same tooth on the other side of your mouth, for the most natural-looking result possible. With the help of the CAD/CAM software, your crown will be designed while you wait. In seconds, the computer will generate a highly accurate 3D model of your teeth.
With a same-day crown, your teeth are simply given a light dusting of reflective powder and then a small scanning wand attached to a computer is used to take digital pictures inside your mouth. If you were getting a traditional crown, the next step would be to take an impression (mold) of your teeth with a putty-like material, and use it to construct a model on which to create the crown. This involves removing any decay that's present, and shaping the tooth with a dental drill so that it will fit perfectly inside the crown. The process of crowning a tooth starts out the same way, whether it's a same-day crown or traditional crown: with “preparation” of the tooth. And the amazingly lifelike appearance of a same-day crown means that no one will know your tooth has been restored. Now you can have a restored tooth without the wait.īest of all, studies have shown that CAD/CAM tooth restorations are just as successful as crowns made with traditional materials and techniques. It's an amazing innovation when you consider that traditionally, crowns take two or three visits and just as many weeks of waiting. But these days, there's a much more convenient alternative: same-day crowns made in the dental office.Īdvanced dental technology known as Computer-Aided Design/Computer-Aided Manufacturing, or CAD/CAM, makes it possible to fabricate laboratory-grade crowns and other dental restorations in minutes. Crown fabrication traditionally takes place in a dental laboratory.
A crown is a durable covering that is custom-made to fit over the entire tooth from the gum line up. A tooth that has been structurally damaged by decay or trauma sometimes needs to be crowned or “capped” so that it can look good and function properly again.
