Zirconium Crowns VS Porcelain Crowns

Zirconia Crown VS Porcelain Crown, Finding the Right Fit.

Zirconium crowns and porcelain crowns are popular choices available to treat large cavities in which the remaining tooth would be incapable of supporting a Filling or Onlay. The basic technique for porcelain and zirconium crowns are the same regardless of the materials used to make each crown. porcelain and zirconium crowns are tooth-shaped “caps” that can be placed over your tooth. Think of it like a snug hat for your tooth. The crown restores the tooth's shape, size, strength and appearance. The porcelain and zirconium crown is cemented into place on your tooth and it covers the visible portion of the tooth.

What is Zirconia Crowns?

Zirconia is a metal oxide derived from zirconium, a metal in the titanium family, It contains around 90% zirconium oxide, offering it unique strength and bio-compatibility. and can be found all over the world. Common household items such as dinnerware, pipes, and electrical fixtures are made from zirconia. Because of its natural strength and durability, zirconia is an ideal material for dental crowns. 

German scientist Martin Heinrich Klaproth discovered zirconium in 1789. The metal’s ability to resist corrosion, and of course, the incredible strength attracted researchers for further testing its biocompatibility. As a result, Zirconia crowns initially became extensively used in the 1990s. dental crowns made from zirconium dioxide (chemically unreactive ceramic) are among the most used restoration options since early 2000.

In the white powder form, Zirconia can be easily shaped, pressed to appear like a natural tooth. Thus, it is used as a crucial component in dental bridges, veneers, and crowns. The material is also used in electrical fixtures and dinnerware.

Dentists appreciate Zirconia as it offers the combination of aesthetic appeal and metal-like strength necessary for restorations. In addition, advancements in technology and dental care tools help dentists get the best out of Zirconia.

Restorations made from this all-ceramic material provide real teeth like texture, coloring, and translucency. The material’s only drawback is the lack of support for color customization. Zirconia crowns are best for patients who need posterior crowns, which require a lot of strength for chewing and grinding food.

Features of Zirconia crowns

Some of the critical features of zirconia crowns include:

• Resistant to chipping, cracking, and discoloration.
• Safe, biocompatible material and causes no metal-sensitivity in patients.
• Smooth exterior prevents abrasion to adjoining teeth and gum tissue.
• Multicolored, highly translucent.
• Provides the most natural appearance to the tooth.

What is Porcelain Crowns (PFM)?

As the name suggests, porcelain fused to metal (PFM) crowns are a combination of porcelain and metal. The porcelain overlay is color-matched to your natural teeth, but the darker metal color could show at the gum line, especially if your gums recede. Dentists usually recommend PFM restorations for patients who desire strength and a natural appearance. 

Features of Porcelain Crowns

Since the late 19th century, porcelain crowns have been an industry essential and are prepared from ceramic that consists of compounds such as mica, silica, and Lucite. Some of the crucial features of porcelain for dental crowns include:

• Produces the most attractive and natural cosmetic result.
• Usually, needs less tooth preparation.
• Most commonly preferred for front teeth that are prone to less pressure and wear.
• Reduces temperature sensitivity because it’s a poor conductor of heat or cold.
• Requires testing in patients with metal sensitivity.

What to Expect During the Procedure: Zirconia Crown and Porcelain Crown

Patients should plan to obtain their porcelain or zirconia crowns in two distinct appointments. During the initial visit, the dentist will prepare the tooth which may include some enamel contouring. The dentist will also remove the decay from the cavity. Once the tooth is contoured and cleaned, your tooth impression will be molded and referred to the lab. 

Your porcelain or zirconia crown will be uniquely customized for an individual fit. Once your crown is ready, the dentist will attach it above your natural tooth at the time of your second appointment. The dentist will make any last minute alterations to perfect the shape and size of your crown, and cement it permanently over the natural tooth.

Both porcelain and zirconia crowns usually last around 10 years, subject to proper dental care.
