Same-Day Crowns (CADCAM)
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. A crown is a durable covering that is custom-made to fit over the entire tooth from the gum line up. Crown fabrication traditionally takes place in a dental laboratory. But these days, there’s a much more convenient alternative: same-day crowns made in the dental office.
Advanced 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. It’s an amazing innovation when you consider that traditionally, crowns take two or three visits and just as many weeks of waiting. Now you can have a restored tooth without the wait.
Best of all, studies have shown that CAD/CAM tooth restorations are just as successful as crowns made with traditional materials and techniques. And the amazingly lifelike appearance of a same-day crown means that no one will know your tooth has been restored.
How It Works
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. 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. But the similarities end there.
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. 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. In seconds, the computer will generate a highly accurate 3D model of your teeth. But it gets even better.
