The use of a dental crown combined with a dental implant is becoming increasingly popular. This restoration can be used to replace missing teeth or teeth which are damaged beyond repair and require extraction. They can also serve as an anchor for a dental bridge or partial dentures.
Porcelain and gold were previously the most common materials used to create a crown. Porcelain is very natural in its appearance, however, it is also more likely to chip. Gold crowns are relatively affordable, but do not look natural. Patients are also more likely to have an allergic reaction to a gold crown.
Zirconia crowns are a relatively new solution which are quickly becoming popular with both dentists and patients. These crowns are incredibly strong, attractive in their appearance, and biocompatible which makes it highly unlikely for patients to have an allergic reaction.
Zirconium is a strong type of crystal with numerous benefits. Crystal is known for being indestructible with a long life expectancy. Because it is biocompatible, it is easily accepted by the human body and complications are rare. As a result, zirconia is an excellent product for use in dental and medical products. Top advantages associated with zirconium crowns are summarized below.
Longevity
Zirconia crowns last longer compared to porcelain restorations because it is more resistant to damage from cracks and chips.
Durable
Zirconia is made from crystal, making it virtually indestructible. Crowns made from zirconia are able to withstand routine activities and the strong forces from chewing. It is nearly five times stronger than porcelain. The process for milling zirconia crowns makes it incredibly difficult to damage. The crowns can withstand hot and cold temperatures, which helps prevent tooth sensitivity. Sensitivity is quite common in crowns made from other materials. Because zirconia crowns are resistant to chips and cracks, they last longer.
Customized
The dentist can easily adjust the size, shape, and color of zirconia crowns. Because the crown can be customized, it can be made to closely match the natural teeth.
Appearance
Zirconia can be nearly undetectable from the natural teeth. Because the crowns are made from crystal, they are naturally translucent, allowing them to closely match the natural teeth. This material is often preferred over porcelain.
Coverage
Zirconia is preferred by many patients over porcelain alternatives for concealing damage from a fracture or staining.
Metal
Gold and porcelain crowns unfortunately contain metal which may be visible. The visible metal is especially common near the gum line or when the patient smiles. Zirconia crowns do not contain any metal and eliminate the dark appearance.
Natural Teeth
When the dentist is placing a traditional crown, a portion of the natural tooth must be removed. This is necessary for the tooth to accommodate the crown and to help ensure it fits properly. Because zirconia is so strong and durable, only a thin layer of the natural tooth must be removed in preparation for the crown.
Zirconia crowns are an exceptional method used to restore damaged teeth. The restorations are strong, durable, comfortable, and natural in their appearance. If you have damaged teeth which you would like to repair, follow up with your dentist to determine if a zirconia crown may be a good solution.
