Zirconia dental lab offers multiple color options that correspond to the Vita Classic Shade Guide plus bleaching shades are available. Custom staining allows the finished Zirconia restoration to blend seamlessly with existing restorations and natural teeth. Minor adjustments may be made at chairside using a combination of green stones or diamond burs. Cementation is achieved via mechanical retention using a glass ionomer resin dental cement.
The average lifespan of Zirconia crowns is currently unknown. Zirconia crowns are relatively new to dentistry as compared to other types of crowns. Therefore, longevity studies are currently unavailable. The average lifespan is estimated to be approximately 20 years. Of course, how long any dental restoration lasts in vivo depends heavily upon the home care and habits of the individual patient. Milled Zirconia crowns became commercially available in Zirconia has a long history of use in the human body.
Its strength and biocompatibility make it the ideal, safe choice for a restorative dental material. Many patients are concerned about the use of metals in dental restorations and how they may lead to adverse health effects.
With Zirconia, this concern is alleviated because the material is chemically unreactive. It must be highlighted that dental specialist in the field of prosthodontics are trained and qualified to make individual assessment of each patient and customize treatment plan using zirconia based prosthetics that can cater your functional and aesthetic demands. Like many other dental procedures, there can be potential disadvantages to getting a zirconia crown. One potential disadvantage of a zirconia crown is its opaque appearance, which can make it look less than natural.
This is especially true for monolithic zirconia crowns, which are made just from zirconia, although it may be less of an issue for teeth in the back of your mouth. Some dentists have been hesitant to use zirconia crowns in some circumstances for fear that the hardness of the zirconia could cause wear and tear on opposing teeth.
While that may be a concern, a study found that feldspathic porcelain was much more likely than zirconia ceramic to cause wear on the enamel of opposing teeth. In general, dental crowns in general can be very pricey. Zirconia crowns typically cost more than other types of dental crowns, such as ceramic, metal, and porcelain. Your geographic location can also affect the cost.

Why are Dental Crowns needed? What is Zirconia Made of? Today, all things considered, zirconia is the best material for dental restorations. I have been in the dental restoration service business for almost 35 years, and I have witnessed a steady climb in the use of zirconia products in dental restorations. I see no reason for it to slow down any time soon. For the past 20 years, zirconia has been the most popular raw material not only in dental prostheses, but also in implanted medical devices in general.
More and more implant parts are using zirconia. Compared to medical-grade stainless steels or titanium, zirconia fares better and offers more advantages. For particularly posterior dental prosthetic restorations, the only material that offers more benefits in terms of biocompatibility is gold.
However, gold is no longer affordable to many patients. In addition, zirconia offers a more natural look. Therefore, zirconia is the best material for replacing missing teeth. Zirconia consists of zirconium dioxide, which has the highest mechanical strength and fracture resistance of all non-metallic materials. Besides the strength, the other main reason it is widely favored in medical devices is due to its superior surface smoothness.
In addition to medical prosthetics, zirconia has been widely used across industry and markets in such products as watches, knives, jewelry, valves, gears, and pumps, to name a few. Zirconia is the most recent arrival in dental materials. Until about , when gold prices soared, zirconia had only a small share of the market in dentistry.
Then, as an alternative to expensive gold crowns, zirconia became a more popular choice among restorative dentists. Additionally, most of those small labs did not have the skill or knowledge to use the new technology. Most zirconia in the market today shares a very similar composition. However, the manufacturing process differs slightly depending on the purpose of the zirconia. For example:. I receive many calls from our clients asking about this brand and that brand, but my answer is always the same.
Regardless of what they call it, most zirconia shares a similar composition. However, it differs according to the manufacturing process, which affects two main characteristics: the strength and translucency or opacity. For example, the opacity of the zirconia blank is directly proportional to the strength. In other words, the strongest zirconia blanks are the most opaque they will be.
Therefore, if you need the highest translucency the least opaque blank for your anterior restorations, the strength is significantly compromised. Still, it may be stronger than other non-metallic dental raw materials. As an experienced dental restoration business owner, I believe zirconia is the best material for dental restorations, primarily based on three reasons: longevity, biocompatibility, and aesthetics. What is Zirconium?
The major advantages of zirconium include: Biocompatibility. Great at hiding tooth damage. Can be easily modified, reshaped and colored. Less tooth structure has to be removed. Aesthetically pleasing. No metal is needed. Leave a Reply Cancel reply Your email address will not be published. Download Our Rx Form. Standard Rx Removable Rx. Recent Posts. Job Openings. Many dentists can make zirconia crowns in their offices rather than sending an impression of your tooth to a lab to have a crown made.
Then, they can cement the crown into your mouth in a single visit. The dentist uses a dental milling machine to actually make the crown from a block of zirconia. This process eliminates the need to stretch the procedure into two visits.
However, not every dentist office has this technology in-house or offers zirconia crowns. Like many other dental procedures, there can be potential disadvantages to getting a zirconia crown.
One potential disadvantage of a zirconia crown is its opaque appearance, which can make it look less than natural. This is especially true for monolithic zirconia crowns, which are made just from zirconia, although it may be less of an issue for teeth in the back of your mouth.
Some dentists have been hesitant to use zirconia crowns in some circumstances for fear that the hardness of the zirconia could cause wear and tear on opposing teeth.
While that may be a concern, a study in the Journal of Dentistry found that feldspathic porcelain was much more likely than zirconia ceramic to cause wear on the enamel of opposing teeth. According to some experts , the porcelain layer can make the crown a little more likely to chip or delaminate separate into layers. That may be something to consider. Zirconia crowns typically cost more than other types of dental crowns, such as ceramic, metal, and porcelain.
