Background:
Cell culture studies may provide information on the behavior of biomaterials in the intended implant environment. Cell cultures from such an environment could be used for the development of middle ear implants.
Material And Methods:
Secondary bone-like cell cultures derived from human stapes were exposed to different materials [Al(2)O(3) ceramic, glass ceramic (Ceravital), gold and titanium]. Proliferation was studied for up to 40 days.
Results:
The proliferation of cultured stapes bone-like cells did not differ significantly between the four tested biomaterials. The well known cytotoxic effect of copper, which was used as a control, was evident.
Conclusions:
Four biomaterials [Al(2)O(3) ceramic, glass ceramic (Ceravital), gold and titanium] have similar biocompatibility and no toxicity when tested in human stapes cell cultures. This in vitro model may be of considerable value for the further development of middle ear implants, e.g., when coated with bone morphogenetic proteins.
