Comparison of calcium phosphate glass ceramics with apatite ceramics implanted in bone. An interface study--II

In order to study bone tissue interaction on calcium phosphate glass ceramics and on apatite ceramics, cylinders of standard size were implanted in the tibiae of rabbits. The materials were evaluated by radiography, light microscopy and microradiography. Apatite ceramics gave rise to a very close contact with new bone. Glass with an apatite surface evoked bone growth similar to that for apatite ceramics but with a loose contact while glass without an apatite surface gave rise to porous remodelling of new bone without close contact to the implant.
