Dental Crowns

Dental crowns can be classified in two categories, 1. Temporary crowns and 2. Permanent crowns.

Temporary Crowns: These crowns are placed when something is needed to cover a tooth very quickly, to be used for a short period of time, while waiting for a permanent solution. These crowns are made of various materials such as acrylic, aluminum and stainless steel. While some of these are more durable than others don’t expect these to last for any long period of time.

Permanent Crowns:

PFM (Porcelain fused to metal): These are tooth colored crowns that commonly are used on posterior teeth for strength. There are three levels of choice in metal. We use only the high noble porcelain fused to metal crowns, which has the highest gold content. These are currently the most common, but quickly being replaced by more reliable crowns.

GOLD: Gold crowns are the most reliable crowns used primarily on back teeth. They are not esthetically acceptable for front teeth.

PORCELAIN: All porcelain crowns are very esthetic and can be reliably used on front teeth. These crowns tend to be more brittle than normal tooth structure and if the patient is not careful, can easily be fractured.

ZIRCONIA: These crowns have an extremely strong tooth colored base with porcelain fused to the surface. They are very esthetic and tend to be fracture resistant. These do not require any special cementation process and are very reliable.

NEWER TOOTH COLORED CROWNS: There are numerous new crown systems. Some are very promising as they are very hard and fracture resistant while also being very esthetic. As soon as the track record on these crowns has some measurable success they will also be desirable.
