摘  要:作者通过11只家兔实验,经大体形态学、X线、光镜、电镜的观察表明人工骨植入兔下颌骨有良好的生物相容性,有骨引导作用,界面为骨性结合,与自体骨移植比较有类似的作用。临床上应用在外伤性骨缺损的8例,骨愈合良好,无排斥反应,是较理想的人工骨代用材料,实用于外伤性骨缺损的修复。22 transplanting operations were performed on two sides of mandibles of 11 rabbits, use dense polycrystal particulate hydroxylapatite were filled into defects of size 1.2×0.7cm^2, the specimens were collected in different period after operations. The observation was taken place under the general mophology, X-Ray, light microscope, and transfer electron microscope. The results indicated that HA have good biocompatibility and evidence indicated they have osteoconduction effect. Clinial appication 8 cases show that the dense polycrystal particulate hydroxylaptite is a quite ideal artificaiel bone. It has very good biocompatility, all patients are satisfied with the results.
