Metal supported porcelain crowns can be used to replace a single tooth, or as a bridge. The metal alloy in the substructure of the tooth formation is extremely durable but has low light transmittance.
These crowns are more robust and durable and are generally used for the rear teeth (molars) that are exposed to pressure when chewing. Metal-supported porcelain crowns are often used in tandem with implants.
However, metal-supported porcelain crowns are not often used to replace front teeth, as they do not transmit light effectively. When designing a new smile for our patients we recommend veneers with higher permeability and more natural appearance such as zirconium and ‘E-Max’ for these anterior teeth.
The dental technologies available to us in our in-house laboratory allow us to create high-quality dental coatings over the metal alloy substructure of the crown. This is achieved using a fine spray for coating the metal before being baked in a high-temperature oven. The result is a very durable finish that will harmonize with the patient’s natural teeth.
