Inductively coupled argon plasma spectroscopic analysis was used to quantify titanium aluminum, and vanadium corrosion products released by superficial layers of identically shaped commercially pure titanium and Ti-6Al-4V alloy dental implants. Halves of each of two originally sterile groups were analyzed directly from the manufacturer's packaging and the other halves received glow-discharge treatment prior to their corrosion assay. The implants were incubated in pH 3 modified saline solution and were analyzed after 2- and 12-week corrosion periods. Implants treated with glow discharge showed statistically significant reduction in the amounts of corrosion products released, apparently as a result of glow-discharge-produced surface oxides of greater passivity than originally present.
