For teeth that are badly damaged, dental crowns can be an effective treatment option. The dental crown procedure utilizes tooth-shaped coverings made of metal, ceramic, or porcelain to restore strength and eliminate discomfort. In addition, dental crowns may be used to anchor a dental bridge or to cap a dental implant post.
Dental crown procedure is completed in two stages. During the first stage, the dentist removes portions of your natural tooth’s structure to accommodate the dental crown. Surrounding teeth may also be prepared in this way. An impression is made and sent to the lab, where your dental crown is created in about one week. A temporary crown will be in place between visits to ensure the most natural look and feel. When you return to the dentist’s office, the temporary crown is removed and your new, custom dental crown is securely bonded in place.
Zirconia crowns can look beautiful and very natural. Zirconia is an extra tough ceramic material, and it can be made extra thin. They have no metal in them, and can be made translucent or opaque, depending on the demands of the situation. If they are bonded onto the teeth, and not just cemented with conventional dental cement, they won't show a black line at the gumline years later, the way porcelain fused to metal crowns do.
The crown consists of two separate components, the core and the porcelain. The Zirconia Core is designed to be as resilient as any metal copings used for traditional PFM crowns. And over the years the Zirconia Crown has been proved as a superior replacement for crowns of similar composition, such as the Java and the Procera Crown. It is also a desirable replacement for PFM crowns, especially for patients with metal allergies.
