Zirconia Crowns

Zirconia Crowns

Dental materials should be able to resist repetitive chewing force. They should be biocompatibility, chemically stable, do not erode opposing teeth and be aesthetic at the same time.

Metal-ceramic restorations are traditionally the most commonly used method of restoring lack of both the posterior and anterior teeth. However, natural dental aesthetics is not provided with metal restorations.

Zirconia can be successfully used in high strength and hardness and lack of front and back teeth. It is more biocompatibility with gum compared to metal. There is no gray coloration that appears with the metal gum reflection in the time. Because zirconia is designed and manufactured with CAD-CAM technology (computer-aided design and manufacturing), there is no possibility of error, compared to metal. Whiter teeth can be made zirconia compared to metal. However, it is more accurate to use glass ceramics in the front teeth so that the light permeability is the same as that of natural tooth enamel. The aesthetic dentist determines which material will be used according to the result of dental examination.
