Major material losses in teeth and tooth deficiencies in the mouth can be restored with crowns and bridges. For this purpose, metal-supported porcelains have been used safely for many years. With the development of technology and new materials, zirconia restorations have also been widely used. Zirconia, which is a kind of compound of zirconium metal, is both durable and a more aesthetic material because it is white in color. Thanks to these properties, it is suitable for use in the treatment of anterior teeth and posterior teeth where chewing forces are concentrated.
Zirconias have become more preferred because of the disadvantages of metal-supported restorations such as matte appearance, gray metal reflection and causing discoloration on the gingiva. In addition , zirconia , crowns and bridges can be used successfully for a healthy and beautiful smile because their light transmittance is close to natural teeth, they are very compatible with the oral tissues and do not cause any harm.
