Porcelain-Fused-to-Metal

(PFM) Crowns

 

The porcelain-fused-to-metal crown has been a standard in restorative dentistry for decades. The predictability and reliability of PFM crowns have allowed them to stand the tests of both time and technology. In fast, they have been in use for more than 40 years.

 

Porcelain-fused-to-metal crowns can be thought of as a hybrid between all metal crowns and all-ceramic crowns, in the sense that they made from both metal and porcelain. When they are fabricated, the dental technologist first makes a shell of metal that fits over the prepared tooth. As this shell can be shaped for a very accurate fit, the PFM crown resists leakage. Porcelain is then fused to the metal shell, in a high-heat oven, thus giving the crown a white tooth-like appearance. It is through this manufacturing process that porcelain fused-to-metal crowns obtain their advantages. Because the base substructure is made metallic alloy, the crown is very durable. Also the base of the PFM crown is extremely stable. Because it is fused, the crown doesn't tend to get loose with time and usage.

 

PFM crowns still remain a popular choice for many dentists. At Precision Ceramics Dental Lab, our porcelain-fused-to-metal cvrowns are manufactured with the highest standards of quality.
