Metal Porcelain Crowns
Also known as Porcelain-fused-to-meal (PFM) crowns, metal porcelain dental crowns are one of the types of dental crowns composed of metal and porcelain materials. The metal component of this type provides strength and durability, while the porcelain component gives a natural appearance matching the color of the patient’s existing teeth. Metal porcelain crowns are often employed for teeth in the back of the mouth, where strength and durability are crucial to endure the pressure of biting and chewing. It should be noted that over time, the metal component of this type of crown can become noticeable as a dark line near the gumline.
Emax Crowns
Emax crowns, made of all-ceramic materials (lithium disilicate or zirconia oxide), are known for their strength and durability, making them a long-lasting option for patients; they are an aesthetic treatment option be used to repair cracked or fractured teeth. Emax crowns can also closely match the color, transparency, and texture of the patient’s natural teeth and provide natural-looking restoration. Emax crowns which are biocompatible, require minimal tooth preparation, which can help to preserve more of the patient’s natural tooth structure.
Zirconia Crowns
Zirconia crown, a popular choice for dental restoration, is a type of ceramic material that is extremely strong and resistant to wear and tear. Zirconia crowns requiring minimal tooth preparation provide patients with a natural appearance and reduce sensitivity to hot or cold temperatures. Additionally, zirconia crowns can be precisely fitted using computer-aided design (CAD) and computer-aided manufacturing (CAM) technology, resulting in a more accurate fit.
