摘要
ＥＡＭ树脂与羟磷灰石（ＨＡ）按一定比例调和形成一种新材料－ＥＨ型复合材料．对ＨＡ／ＥＡＭ不同重量比的ＥＨ型复合材料人工骨进行抗压强度和抗弯强度测定。结果表明：１．ＥＨ型复合材料的抗压和抗弯强度随ＨＡ含量的增加而增加。２．ＨＡ／ＥＡＭ为３／２和２／１的两组ＥＨ型复合材料的抗压和抗弯强度十分接近，而ＥＡＭ树脂含量增加，更易塑型。因此，我们把ＨＡ／ＥＡＭ为３／２的ＥＨ型复合材料作为我们实验和临床应用的标准材料。
ixing both EAM resin and hydroxyapati.. in a constant proportion formed a new material--EHcomposite material , which can ameliorate the disadvantage of hydroxyapatite which is liable to breakand difficult to be moulded during operation. EH composite material artificial bone in the different ratioof HA/EAM by weight was measured in the light of compressive strength and bending strength. Theresults showed that: (1 )The compressive and bending strength of EH composite material increased withthe increases of hydroxyapatite content. (2)The compressive and bending bending strength of two groups of EHcomposite material(HA/EAM= 3/2, 2/1 )were quite close. The moulding is eater with the increase ofEAM resin content. Therefore the EH composite material with the ratio of HA/EAM ￣ 3/2 wasregarded as a standard material that we used in experiment and clinical practice.
