摘要
目的：通过β－磷酸三钙（β－ＴＣＰ）陶瓷兔颅骨骨膜下的埋植实验，观察在未造成新鲜骨创面的情况下，β－ＴＣＰ陶瓷在皮质骨表面的引导成骨作用，并探讨其用于萎缩牙槽嵴重建的可行性。方法：使用显微镜用测微尺测量新骨从骨表面长入材料内的高度，并和羟基磷灰石（ＨＡ）陶瓷对比。结果：经过两组对照观察，实验组和对照组在各时间点组新骨生长高度相差显著，实验组优于对照组。
Objective:To study the osteoconductivity of porous block β tricalcium phosphate (β TCP) on intact bone surface.Methods: β TCP was implanted subperiostealy onto cortical bone surface of calvarium;new bone was measured under microscope quantitatively as the height of the new bone from the surface of cortical bone to the interior of material.Hydroxyapatite (HA) implant was used as the control.Results:Higher new bone was observed in experimental groups than in controls.Conclusion:Osteoconductivity of β TCP ceramic on the surface of cortical bone is superior to that of HA ceramic.
