title: [An experimental study of morphologic and element analyses at the interface between bone and substitutive materials for human bone tissues].
abstract: The implant materials chosen in this study included hydroxy-poly (calcium natrium phosphate), hydroxyapatite, bioglass ceramic and Ti-6Al-4V. The implants were inserted into the mandibles of dogs. The samples from dogs were regularly observed by X-ray examination, optical microscope, scanning electron microscope and X-ray energy spectrograph. The results showed that all the implants had integrated into the surrounding bone tissue by the third month. During the early stage of the experiment, there were a lot of S, Si at the bone-implant interface. After new bone became mature, the contents of Ca, P increased, but the contents of S, Si decreased at the interface.
