IN T RODUC T ION

The authors have shown for glass-ceramic A-W and its families, that bioactive, i.e., bone-bonding, glasses and glass-ceramics form an apatite layer on their surfaces in the body, whereas nonbioactive glasses and glass-ceramics do not form the surface apatite Similar dependence of bioactivity on formation of the surface apatite layer also has been reported for Bioglass-type glas~es."'~ These findings indicate that the essential condition for glasses and glass-ceramics to bond to living bone is formation of the apatite layer on their surfaces in the body.
