Abstract

Ceramic materials have various superior characteristics in mechanical properties, heat resistance and chemical stability. To make the best use of these superior characteristics, ceramics have been considered as the candidate materials for biomaterials used for tooth root, artificial bone and so on. In recent years, the necessity of biomaterials has been increased more and more with an ageing society. Biomaterials mean the materials specially designed for the repair, reconstruction, and replacement of diseased or damaged parts of the human body. Apatite, glass ceramics, alumina and so on have been used as artificial bone and dental implant materials. From among these kinds of ceramic materials, alumina is a candidate material for bio-ceramics, because of its superior strength characteristics, corrosion resistance and bio-inert
