ABSTRACT

Bioactivity studies of silicate bioceramics testifies by formation of hydroxyapatite layer on the surface of sintered body, which arises with the passage of socking time, when investigated by socking in simulated body fluid. Biologically compatible ceramics are called as bioceramics and synthetically prepared bone mineral is called as biomimetic material as it resembles the natural inorganic substance present in the bone. Both are used in hard tissue application as they can actively interacts with the biological environment and chemically integrate and forms direct chemical bond with the surrounding bone tissues. Important characteristic of biological fixation is that chemical bonding occurs across the interface between an implant and the tissue with strength equal to or greater than that of the bone. Surface characteristics and crystallite size play a major role in determining biological studies of diopside.
