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 in one visit. 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. 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 scanned into a computer with a scanning wand. The canning wand takes digital pictures inside your mouth. In seconds, the computer will generate a highly accurate 3D model of your teeth. But it gets even better. With the help of the CAD/CAM software, your crown will be designed while you wait. Then a block of dental ceramic material is chosen in the shade that most closely matches your own teeth. The computer's digital design is transmitted to a milling machine that carves the crown from the ceramic block in about 5-10 minutes.
Once the permanent crown has been created a glaze is applied and fired. Then the permanent crown is cemented on your tooth. With a traditional crown, you would have to wear a temporary restoration for several weeks while the permanent crown was being fabricated at the lab. With a same-day crown, you walk out with the real thing.
