Crowns 
Imagine a world in which computers and the Internet are used to fabricate tooth-colored ceramic fillings and crowns. Futuristic sounding? Not at all. Today, using advanced-generation computer design technology, dentists can produce and create natural looking teeth restorations conservative of tooth structure with CEREC 3 and PROCERA.

 
 
 

CEREC 3

CEREC 3 is a high tech system that quickly and economically restores damaged teeth using a durable ceramic material that matches the tooth's natural color. This chairside technique can yield natural-appearing results, which rival any laboratory fabrication.

How it works
After the damaged tooth has been prepared, a thin layer of reflective powder is sprayed directly on the tooth surface. A special camera takes an optical impression of the tooth, feeds it into a computer next to the dental chair, and in just fifteen minutes, mills the final inlay, onlay, crown, or veneer out of a solid block of ceramic material. The restoration is designed from this scan and then automatically milled out from a solid block of ceramic material. Finally the newly milled restoration is accurately fitted and durably bonded to the prepared tooth. This ensures a perfect marginal seal between the filling and the tooth. There is no "gap" through which bacteria can penetrate and cause dental decay.

Safety features
CEREC restorations are made from ceramic, a natural substance that is particularly compatible with the body. The CEREC ceramic has the same characteristics as normal healthy dental enamel.

Patient benefits
With CEREC 3, there are no temporary fillings or crowns and no messy impressions. The ceramic is so smooth that bacteria do not adhere to the surface. This fascinating treatment process results in clinically tested, long-lasting targeted restorations that conserve as much tooth structure as possible.

All Ceramic Crowns

PROCERA and ZIRCONIA crowns are all ceramic tooth-colored restorations that utilize the Internet for its accurate fit. After sending an impression of the prepared tooth to the dental lab, an accurate model of the tooth is made. A probe accurately scans the surface of the model and stores the information in digital form creating a third computerized replica of the prepared tooth. This digitized image is then fed into a computerized milling machine that fabricates an all ceramic shell that accurately fits the prepared tooth. Within two days, this shell is returned to the laboratory where the final layer of porcelain is added resulting in a life-like tooth-colored crown.
