9 THE METAL-CERAMIC CROWN PREPARATION. In many dental practices, the metal-ceramic crown is one of the most widely used fixed restorations. This has resulted in part from technologic improvements in the fabrication of this restoration by dental laboratories and in part from the growing amount of cosmetic demands that challenge dentists today.
The porcelain jacket procedure consisted of taking a broken tooth and rebuilding it with a porcelain covering (the jacket) to make it appear new again. The porcelain jacket crown was very effective for the day, and widely used until the 1950's, when a stronger solution – the porcelain-fused-to-metal crown …
Just as their name implies, all-ceramic dental crowns are restorations whose full thickness is made entirely of a glass-like substance, such as porcelain. The original type of all-ceramic was the "porcelain jacket." Nowadays, instead of porcelain it's much more likely that an "engineered" compound is used.
Composite models representing porcelain-fused-to-gold restorations were constructed from photoelastic plastics. Better stress distributions resulted when the porcelain-gold joint was as far as feasible from the loading site, a bulk of gold was present on the lingual shoulder, and the porcelain-gold joint at the shoulder was 30° from the horizontal.
One of the disadvantages of all-porcelain crowns is the fact that they need more reduction of tooth structure, even more than in case of PFM crowns. More Costly; As a rule, all-porcelain crowns tend to be more expansive than PFM crowns. Porcelain-fused-to-metal Crowns. Porcelain-fused-to-metal crowns are made of both porcelain and metal.

Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic. Metals used in crowns include gold, palladium, nickel, or chromium. Metal crowns rarely chip or break, last the longest in terms of wear down, and only require a small amount of tooth to be removed.
