Crowns are placed on teeth with more extensive decay or teeth that have had a root canal treatment. Crowns fit over the entire circumference of the tooth, providing support and a barrier for the healthy tooth structure underneath.
Crowns can be made from a variety of material – metal, porcelain fused to metal, or all porcelain. In most cases, we will use all porcelain crowns. Modern porcelains, such as Zirconia are very durable and strong enough to withstand the forces of chewing and biting. Zirconia crowns have been shown to have a life expectancy equivalent to that of metal or porcelain fused to metal. Also, because all porcelain crowns are fabricated from a single material there is no risk of the porcelain separating or chipping off of the metal structure, which can happen with porcelain fused to metal crowns.
All Porcelain Crowns in just one visit with CEREC – No Temporaries, No Second Appointments and No Messy Impressions
What Can Patients Expect?
Along with inlays and onlays, we also use the CEREC 3D computer system to make crowns in just one visit – about a 90 minute appointment. After the decay is removed and the tooth is prepared, the tooth and surrounding areas are scanned with a small 3D camera. The digital impression is more precise than traditional impressions. After a digital impression is captured, our dentists use computer software to design a custom crown that fits precisely over the healthy tooth structure. The crown is then milled from porcelain material, and tried in the mouth. Finally, the crown is cemented and the bite is adjusted.
