Zirconia crowns are incredibly durable and match the look of natural teeth well. Zirconia is a white, powdered metal oxide. Like other common dental crown materials, it is a ceramic. It has many properties that make it an excellent choice for the dental crown material. These include natural, white colour, high hardness, and high fracture toughness with no chemical corrosion.
A well-made, quality crown shouldn’t have any defect or require replacement before five years. Some dentists can create and fit Zirconia crowns in a single day. If an order must go through a dental lab, it will take a few days or weeks before the finished crown arrives at the dental office.
Because of their exceptional durability and strength, Zirconia restorations generally last longer than porcelain. While porcelain crowns usually need replacement after a few years, Zirconia crowns have shown a 99 % survival rate after five years.
