Glassy Palladium Alloy to Be Used for Dental Implants?

Glassy palladium rods, with diameters ranging from 3 to 6 mm

Perhaps, but more study is definitely needed.
The palladium alloy described in the paper could soon be of use in biomedical implants, says Demetriou. "One example is dental implants," Demetriou says. "Many noble-metal alloys, including palladium, are currently used in dentistry due to their chemical inertness and resistance to oxidation, tarnish, and corrosion. Owing to its superior damage tolerance, the present palladium glass can be thought of as a superior alternative to conventional palladium dental alloys. Plus, the absence of any elements considered toxic or allergenic—nickel, copper, aluminum—from the composition of this alloy will likely promote good biological compatibility."
Titanium is used today. It has been shown to be bio-compatible and patients have enjoyed a high rate of success. The use of this material may be promising but as always there are concerns over how the material can be manipulated for dental purposes, the bio-compatibility factor and the cost.
