Dental Crowns


Rendering of jaw with dental crownThe team here at Star City Dental are experts when it comes to dental crowns. What are dental crowns? Think of your tooth like the body of your car - when your car gets a bump, a dent or a rust spot, a body shop specialist will cover and reinforce the damaged areas. They may use epoxy putty and sand it smooth to match the rest of the car before painting. The same thing applies to your tooth. Should your tooth have badly worn areas, a crack, a dent, damage from tooth decay, or even irreversible discoloration, we can have the tooth coated with any number of materials. This will cover and reinforce the damaged areas with a like-new appearance. This tooth coating is what’s called the Dental Crown.

Which Materials are Used?


A dental crown can be made with a number of materials, and which you choose will depend largely on your budget. They can be divided into several groups.

The most life-like material used for dental crowns is dental ceramics, or porcelains. While these may beat out the metallic coatings in looks, they are generally brittle and easy to chip or even fracture. Silica is perhaps the most lifelike in this group because of its glass structure, but because of that reason, it is the most brittle, followed by Alumina, or Aluminum Oxide. Alumina has the advantage of being more easily formed than silica, which needs to be fired while forming just like glass.

Alumina is also stronger mechanically because of its Aluminum components in its molecular structure. Also, Zircon, a relatively new material, is even stronger yet since zircon is a crystalline silicate-based material that occurs in nature. It also strongly mimics real teeth like silica. However, zircon is the least convincing out of the three dental porcelain types in they generally are used to coat back teeth.

Metallic alloys as dental crowns due to their strength, their ability to be easily formed, and biocompatibility. Metallic crowns can be divided into noble/high-noble alloys, and base metal alloys. Nobel/high-nobel alloys are mostly gold alloys with other metals including platinum, zinc, and nickel. Their advantages are their durability strength even in thin layers while mimicking the softness of natural tooth enamel so they could prevent excess wear from opposing real teeth.

More Durable and Less Costly


Base metal alloys can include Silver-palladium, Silver-palladium-copper, and Titanium, to name a few. They are rarely used to make full metal crowns – instead, they are more often used as bonding alloys. The advantage is they are less costly, are more durable and stronger than nobel/high-nobel alloys. Unfortunately, the disadvantages are they could start excessive wear on the opposing teeth, natural or otherwise.
