What’s a Crown?
An artificial crown is a non-removable restoration that covers a major portion of the visible part of a natural tooth. A crown can be used for a tooth or dental implant restoration. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. A crown can be made of porcelain, gold or synthetic materials.
E-max crowns are made with Ivoclar Vivadent’s patented lithium disilicate material is truly revolutionary, a material that combines high strength and high esthetics into one product. E-max has optimal translucency, durability and strength.
Studies show that e-max is bio compatible. E-max matches the biological environment of the body and does not cause unwanted reactions.
- Very strong
- Great esthetics
- Bio compatible
- Superior translucency and light diffusion properties
- Replicates natural tooth very well
One of the most difficult areas in dentistry today is the restoration of dental structures with biocompatible materials that are strong enough to withstand the forces of chewing (500-1000 lbs. pressure on molar teeth). Recent technology now offers a material called Zirconium oxide that is attractive, strong, pure, biocompatible and capable of being used for single or long-span dental bridgework. Zirconium oxide is manufactured and optimized industrially so that the material qualities remain unchanged through the complete production chain.
Zirconium oxide has the following superior characteristics that make it ideal:
- Excellent biological compatibility
- Can be used anywhere in the mouth
- Outstanding physical and mechanical qualities
- Strength and Elasticity
- Extremely high density
- Translucence makes excellent cosmetic results possible
- Equivalent fit
- No pulp irritation
- Minimally invasive preparation
All Gold Crown
Another popular option is an all gold or full gold crown. Two features that make these crowns popular are superior strength and less abrasive to opposing teeth.
- Many dentists prefer this type for posterior of mouth
- Some patients prefer the look of gold in their mouth
- Very strong
- Less abrasive to opposing natural teeth
- Wears similar to natural enamel.
One common type of dental crown that was used in the recent past was the porcelain fused to metal or PFM crown. PFM crowns are a cosmetic alternative to metal crowns. They combine the durability of metal crowns with the attractiveness of ceramic ones. These crowns are made less frequently due to the introduction of E-Max and Zirconia crowns.
- Same color as natural teeth
- Standard of dentistry for 30 years
