Zirconium crowns are an excellent, modern, and completely metal-free alternative to metal-ceramic crowns. As their name suggests, they are made of multiple layers of zirconia - an extremely durable and resistant crystal that brilliantly mimics a natural tooth.
Zirconium crowns have a high degree of biocompatibility, meaning they are made of a material that quickly and easily adapts to our body.
Zirconium crowns are reliable and easily adaptable to the individual needs of the patient. Zirconia is an extremely strong, robust, and resistant material, suitable even for patients who grind their teeth in their sleep. Research shows that it is up to five times stronger than other restorative materials and lasts up to 10 years. When placing zirconium crowns, the reduction (grinding) of healthy teeth is minimal.
Making Zirconium Crowns
Zirconium crowns are made of a monolithic white material that mimics a natural tooth with its translucency. If the rest of the tooth is more strongly pigmented, they can be subsequently colored and/or contoured to fit into the dental row. The production time for a zirconium crown is significantly shorter than for other prosthetic variants. The price of zirconium crowns is significantly lower than the price of other metal-free crowns.
Before zirconia began to be used in dental prosthetics, dental bridges were made from gold alloys or stainless steel. These metals are strong enough to withstand the pressure of chewing, but they do not have superior aesthetic properties because metal does not transmit light.
As already mentioned, full zirconium crowns are made of a monochromatic, monolithic material, so they are mainly applied in the posterior region of the jaw.
The advantages of zirconia over other materials are:
- It well imitates natural teeth.
- Extremely strong and sturdy material
- Improved transparency and natural look
- Bio-compatible material - does not cause unwanted reactions in human tissue
Tooth crowns are extremely durable and provide a long-term solution for patients. In order for a tooth crown or dental bridge to be placed in its place, our dentist must remove a part of the natural tooth. More than 60% of the placed crowns endure long. They can last at least from five to ten years after they are placed.
The key to the longevity of crowns and dental bridges is their maintenance.
