Metal Porcelain Crowns
These cases are the most widely used today and are a combination of a strong metal as a core surrounded by an outer layer of porcelain. It offers durability and is aesthetically satisfactory. The metal core can be a semi-precious or gold alloy. Gold is more aesthetic because it shines internally giving a yellowish tinge of dentin like a natural tooth.
Metal porcelain cases are a very good, economical solution. They cost less compared to zirconia crowns, have a gray metal frame and approach aesthetic results of natural teeth due to their outer porcelain build up. At the same time, they emphasize the smile and meet high standards that may exceed your expectations.
