[Comparison of the biological tolerance of titanium and titanium alloys in human gingiva cell cultures].
Mirror-finished solid specimens of pure titanium and the titanium alloys Ti-6Al-4V as well as Ti-5Al-2.5Fe showed no effects on the growth behavior and cell morphology of human gingival epithelial cell and fibroblast cultures. The growth of the cells contacting all three materials was uninhibited. SEM revealed growth of fibroblasts on the surfaces of the specimens, too. No differences could be found between the biocompatibility of titanium alloys and that of pure titanium. The formation of a stable surface oxide layer providing resistance to corrosion may be decisive.
