Of the late two years,in order to find out a kind of dental implant ing materialwhich would possess both the very good properties of biological compatibility,the chemical compatibility and the mechanical compatibility,an animal experi-mental preselection was accomplished by our research team with six kinds of im-planting material chosen from four main sorts of oral implant ing material(met-al,ceramic,high polymer and carbon),As the result of the Preselection,thematerial……bio-ceramic was chosen by ...

为了寻求生物相容性、化学相容性和力学相容性均好的种植材料，在口腔四大类种植材料(金属、陶瓷、碳素、高分子)中，选用6种材料作了动物实验预选。根据预选结果，选定以生物陶瓷为主攻方向，从而研制成功锆磷灰石陶瓷，以之进行了理化性能、生物学性能、及动物实验考查，合平种植要求。并以考查结果与钛合金、多晶氧化铝、单晶氧化铝、钛合金喷涂氧化铝、低温各向同性碳、聚砜种植作了比较，主要性能均较其它几种比较材料为优。经临床初试，锆磷灰石陶瓷的种植效果也较好，其界面为骨性结合。

This could indicates that the formation of oxygen-containing species is the rate determining step for the oxidation of methanol adsorbate.
