Porcelain bonded to precious metal crown is made of a precious metal base and porcelain is then applied in layers over the base. Porcelain crowns can be manufacture to give a tooth- like appearance. They are hand crafted by a dental technician to give characteristics to match the other teeth in your mouth. Porcelain can be crafted to give a high degree of translucency, but because porcelain is inherently a brittle material, sometimes a metal sub-frame will be produced usually made of gold alloy, to increase the strength of the crown. We do not use Nickel –containing alloys.
