Zirconium (zircon, zirconia) is a transition metal discovered in the 18th century. From aerospace to military, zirconium is used in many fields. Because of its corrosion resistance of zirconium, it is a preferred metal in many areas species. Zirconium is white and permeable and therefor it is preferred to be used in dentistry as base of zirconium-ceramic crowns.
What is zirconium?
What are the advantages of zirconia crowns compared to other crowns?
Zirconia crowns have more advantages then metal ceramic crowns. They are translucent and white. Thanks to the transmission of light, zirconia crowns look more similar to natural tooth. Metal crowns do not have this advantage. Contrary to metal crowns, zirconium is resistant to corrosion and therefore the colour does not change and it also does not leave a metallic taste in the mouth. Are zirconium crowns harmful to the body? The zirconium crowns are not harmful to the body. This material is tissue-friendly.
Do zirconia crowns cause for gum pigmentation?
Zirconium does not cause for infections on the gums because it is resistant to corrosion. If the patient takes care of his oral hygiene there will be no problem. Sometimes teeth with root canal treatment change from natural colour. Zirconium beholds his own colour and natural look. In this case the colour change is visible under the thin gum. The origin of the discoloration is not because of the zircon crown but the natural tooth (root).
Is zirconium expensive?
Zirconium is more expensive than metal ceramic crowns. This because zirconium is made by a special 3-dimensional computer program, called CAD/CAM. Also the technicians must work very carefully and precisely. Zircon is more expensive because it is used in many fields in dentistry and it also needs to be prepared in many steps.
Is it possible to make zirconia crowns on implants?
Zirconium can be applied on the implant and it did not show any interaction with the titanium. Does the transmittance of teeth disappear with zirconia crowns? The light transmission of the natural tooth and the zircon crown is identical. It can especially be used by patients who wish an aesthetic look. How long the treatment of zirconium coating? The treatment will take on average about 5 days.
