![]() As compared to the other materials that dentists use for dental crowns, zirconia is relatively new so the data are limited. Lifespan of Zirconia CrownsĪt this point in research and case studies of zirconia crowns, the average length of time you can expect your crown to last is unknown. Porcelain fused to zirconia (PFZ) starts as a full contour zirconia crown with a small window removed and replaced with porcelain to combine the strength of the zirconia with the ideal aesthetic look of porcelain. These crowns are ideal for areas where the teeth are more visible and are not used as heavily. When used strictly in crowns, zirconia can be used in three different types of crowns: full contour zirconia, full contour all translucent zirconia, and porcelain fused to zirconia.įull contour zirconia crowns are the strongest zirconia crowns and are ideal for canine teeth, people who grind their teeth, and those with a heavy bite.įull contour all translucent crowns have a better aesthetic than full contour and appear more like natural teeth. No metals are needed to support zirconia and it is very durable, resulting in a crown that is resistant to cracking.ĭentists have been using zirconia in a number of dental restorations that include full crowns, porcelain fused to zirconia crowns, bridges, veneers, and dental implants. Zirconia dioxide is a metal oxide and can be classified as a ceramic material. ![]() Unlike your natural teeth, your dental crowns made from zirconia are actually made from a tetragonal crystalline compound. If you clench and grind your teeth in your sleep or you have injured your mouth in an accident, you are already familiar with the experience of what some of the circumstances are that can lead to damage to your natural teeth. Just like your natural teeth, you can damage your dental crown. ![]()
