An Investigation of Bonding Mechanisms at the Interface of a Prosthetic Material.
Abstract
The report summarizes evidence developed in this laboratory of direct chemical bonding between glass-ceramic implants and rat femurs. An evaluation of the mechanical strength of the bond is presented as a function of healing time. The histological changes at the bone interface of glass-ceramics with and without surface solubilities are compared as a function of time. Results of solubility studies of the glass-ceramics are presented as are investigations of protein epitaxy and adsorbtion at hydroxyapatite crystallite surfaces. Results from tissue culture evaluation of the soluble and nonsoluble glass-ceramic surfaces are also presented. Finally, a computer approach that makes possible stress analysis of bone cross sections is discussed. (Author)
