[The problem of degradation and histocompatibility of bioactive ceramics in soft tissues. 1. Studies of the degradation of bioactive ceramics in soft tissues].
Following implantation of bioactive ceramics both into the bone and the subcutis the implantat surface changed to be relative rich in Ca and absolutely poor in P as indicated by means of electron microprobe. The implants located into the subcutis however, resulted in a more distinctive alteration of those surfaces. This process caused by the interaction between bioactive vitrified ceramics and the connective tissue can be prevented by coating the appropriate parts of the implants with Dentalceramics. A 10 micron to 15 micron layer may to be sufficient.
