Bioactive materials are investigated for their "osteoconductive" activity. After an analysis of the chemical bond that occurs between the material and the bone in function of the studies carried out in the past ten years, new considerations on the ions diffusing from the implant toward the bone are reported. The results of the research on three diferent types of glasses in granular form implanted in sheep's mandibular pockets are presented. Phenomena of diffusion are seen in all the materials, not only from the material, but also toward the material.

Abstract
Bioactive materials are investigated for their "osteoconductive" activity. After an analysis of the chemical bond that occurs between the material and the bone in function of the studies carried out in the past ten years, new considerations on the ions diffusing from the implant toward the bone are reported. The results of the research on three diferent types of glasses in granular form implanted in sheep's mandibular pockets are presented. Phenomena of diffusion are seen in all the materials, not only from the material, but also toward the material. In one material the entranced potassium, that is not present in its composition was observed.
