Are Zirconium Restorations Really Metal Free?

Is it misleading when we call zirconium restorations “metal free”? We all are agreed that titanium is a metal. Zirconium is chemically a metal and has been used in alloys. Its atomic number is 40. To say that Titanium is a metal and that Zironium is not is showing a poor knowledge of chemistry. Zirconium dioxide, an oxidized form of Zirconium that is used for restorations, is a metal. We would not call rust — iron oxide — anything but a metal. Now we have a new generation of zirconium dioxide implant fixtures and they are advertised as “metal free” and calling them ceramic. How do we explain these seeming contradictions?
