ceramic crowns

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 traditional 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. While porcelain-fused-to-metal crowns remain a popular choice for strong and attractive restorations, there are some drawbacks, such as the visible metal margin at the gumline and their inability to handle light as naturally as dental ceramics.

Advantages of All-Ceramic Crowns:

• All-ceramic crowns interact with light like natural teeth and closely mimic their translucency and luster.
• All-ceramic crowns can be made thinner and require less tooth reduction.
• All-ceramic crowns are kinder to the surrounding tissues, offering potentially healthier long-term results.
• All-ceramic crowns are resistant to stains and discoloration.
• All-ceramic crowns are metal-free and safer for individuals with allergies or sensitivities to metal.

With the range of engineered dental ceramics available today, the material selected for crown fabrication depends on the location of the tooth, the stresses on that tooth, and the esthetic requirements of the case. Certain all-ceramic crowns are better suited for back teeth, while others fulfill the aesthetic requirements of a front tooth. Some of the popular all-ceramic crowns used today include:

• Feldspathic porcelain crowns
• Empress crowns
• Procera crowns
• Lava crowns
• Zirconia crowns
• Emax crowns
