What is this Zirconia stuff anyway?
Zirconium is a grey -white transition metal in its purest form which resembles titanium. Zirconium is very resistant to corrosion and for this reason is most commonly used as an alloying material.

What are the benefits of Zirconia implants?
Zirconia implants are said to provide an improved patient service with a quicker and more patient-oriented implant therapy. As Zirconia is white it has an obvious aesthetic advantage over titanium as it is indistinguishable from natural teeth. The high corrosion resistance of the material means that there is virtually no danger of corrosion with Zirconia tooth implants. In addition some patients may not like the idea of having metal inserted into their mouth in this case Zirconia implants offer patients another more comfortable option.
Are there any risks associated with using Zirconia?
One of the main risks associated with Zirconium based implants is radioactivity. Zirconium at any time can contain a certain number of radioactive isotopes. This can lead to an increased chance of various Oral cancers. Generally implants are produced from Zirconia material with extremely low radiation emission levels however all manufacturers of Zirconia dental implants are asked to produce a declaration of radioactivity for their Zirconium based dental products.
