Abstract
Six kinds of dental implants: Apaceram, Bioceram, Free design blade implant, Shape memory blade implant, Hydroxyapatite-coating blade implant and Vitallium were immersed in three kinds of solutions: Ringer's solution, 1.0% lactate acid solution, and 0.05% HCl solution, for seven days at 37°C. Using an inductively coupled plasma emission spectroscope, the solutions were analyzed. The element solubilities were observed in five kinds of dental implants, except Bioceram.
