In constructing a crown, the combination of materials that provide the most satisfying results is porcelain fused to metal (either gold or non-precious). The metal provides strength, and the porcelain, strength and beauty. The resulting product, a porcelain veneer crown, is giving a lot of people something to smile about.
A porcelain veneer crown replaces the enamel of your tooth. First, a metal thimble is custom made to fit over your tooth. A jacket of porcelain is fused, or veneered, to the thimble. The tooth is prepared so that the completed restoration will rest securely in position, once cemented in place.
Because of its strength and resistance to chewing stress, a porcelain veneer crown is functionally superior. The metal thimble provides strength and durability. The dental porcelain, veneered to the thimble, is extremely hard, highly reflective, and color-stable. Porcelain is much less porous than enamel, so the veneers are more stain-resistant. Porcelain provides beauty and strength equaling that of your original tooth structure.

A molar requires a veneer crown. A metal coping (thimble) is placed on the prepared molar. Then the veneer crown is cemented into place.

The primary goal in dentistry is to restore teeth to their normal form, beauty, and proper function.
Dentists use porcelain veneer crowns to restore teeth that have been disfigured by extensive decay, breakage, abrasion (wearing), imperfect development, or discoloration. Sometimes they are even used to correct poor alignment of the teeth.
