Once commonly referred to as, "porcelain jackets," today's all-ceramic crowns are fabricated from advanced generations of aesthetically appealing, lifelike materials affording strength and durability approaching that of tradition metal and porcelain fused to metal crowns (PFM).
When a tooth requires a full coverage restoration to rebuild its structural integrity and appearance, how good the crown will look and how well it will withstand the forces of oral function are major considerations in choosing the type of crown. In the past, only metal crowns or ones fabricated out of porcelain fused to an underlying substructure of metal offered the strength required to bite and chew without breaking. While porcelain fused to metal crowns to this day remain a popular choice for strong, attractive and long-lasting restorations to rebuild teeth that are damaged, decayed, misshapen, worn down, undersized, or have had a root canal procedure, there are some drawbacks. For one thing, the thin metal margin at the collar of a PFM crown may be visible at the gumline (especially in the presence of receding gums). Also, due to the presence of an underlying metal shell, porcelain fused to metal crowns do not come close to handling light in the same way as natural tooth structure or dental ceramics.
While the trade off between appearance and strength used to mean that porcelain or all-ceramic crowns looked better but did not have the strength and durability of porcelain fused to metal crowns that is no longer the case. All-ceramic crowns are not only capable of producing incredibly lifelike results, but thanks to the range of materials available today, all-ceramic crowns are stronger and more reliable than ever before.
Some of the advantages of all-ceramic crowns include:
With the range of engineered dental ceramics available today, which material is selected for crown fabrication depends upon the location of the tooth, the stresses on that tooth and the esthetic requirements of the case. Certain all-ceramic crowns are more suited for back teeth, while others are able to fulfill the aesthetic requirements presented by a front tooth.
