PORCELAIN CROWNS

Why Porcelain Crowns?

Porcelain crowns replace the exterior portion of the tooth to re–establish its original function and to create a natural appearance. Crowns are the treatment of choice where tooth decay has destroyed most of the original tooth, when a traumatic event has caused damage to the original tooth structure, This may also be an option for people who grind their teeth so much that the original structure of their teeth has been compromised.

An advantage to porcelain crowns is they can not only mirror the original tooth in function, but can be designed to match the original. When patients opt for a porcelain crown for cosmetic reasons, they are usually covering up the front portion of the tooth that has some flaw. A porcelain crown is thicker than a veneer and, in some situations, this thickness is needed to cover the portion of the tooth for cosmetic reasons.

Crowns and veneers are fixed in place using a light sensitive resin between the original tooth and crown, once in place a special curing light is used to secure the crown in place.

Partial crowns or Inlay, An inlay is similar to a filling but the dental work resides completely within the cusps on a tooth’s chewing surface. These restorations are more conservative than crowns, and can be impossible to distinguish from your natural tooth.

You may need a crown to:

  • Restore a broken tooth
  • Support a tooth with a large filling
  • Improve the color and shape
  • Cover an implant

Treatment Steps:

  • Reduce the tooth size
  • Take an impression of the tooth/teeth that crown will be covering
  • Place a temporary crown until the permanent crown is ready
  • Cement the permanent crown

Porcelain Crowns has different types:

  • Metal fused porcelain crowns

A dentistry method that had been used for decades, essentially porcelain is fused to a metal crown and the tooth is a colored ceramic which is baked on top of a metallic alloy substructure called a coping for ultimate strength. The metal sublayer is thin, strong, and fits perfectly over the reduced teeth.

  • Zirconia fuse porcelain crowns

Porcelain fused to zirconia (PFZ) crowns and bridges can serve as a CAD/CAM alternative to the traditional porcelain fused to metal (PFM) restorations. Porcelain fused zirconia can be used for crowns and bridges according to your requirements. When porcelain is layered over zirconia substructure, you get an incredibly strong (1200 Mpa and higher) prosthetic with lifelike translucency. These durable and attractive bridges and crowns are suitable for both anterior and posterior restorations.

  • E-Max fuse porcelain crowns

Emax is a relatively new type of porcelain material that has quickly become state of the art in dentistry. Compared to the classic: Porcelain fused to metal crown that was the standard for decades, there is no junction or fusion of porcelain to any metal, which minimizes the possibility of chipping or breaking.
