โฆ Synopsis
Increasing concerns over the significance of corrosion, wear, hypersensitivity, toxicity, and carcinogenicity with respect to metallic implant materials has stimulated more detailed investigations of the effects of metal ion release upon the in vim system. One quantitative method for assessing this metal release is the electron microprobe. M e a d described this technique when studying the fate of corrosion products of implant materials at the cellular level. He measured the concentration of metallic corrosion products in cells cultured on metal grids i?t aztro and the distribution of metallic corrosion products in implant areas.
