口腔粘接新型材料--磷酸二氢(甲基丙烯酰氧癸)酯的合成与应用

Synthesis and Application of Novel Dental Adhesive Materials of 10-methacryloyloxydecyl Dihydrogen Phosphate

以甲基丙烯酸、1,10-癸二醇和三氯氧磷为主要原料合成出了磷酸二氢(甲基丙烯酰氧癸)酯。用1H-NMR、MS和31P-NMR对产物结构进行了表征确认。通过剪切强度的测试评价了磷酸二氢(甲基丙烯酰氧癸)酯对复合树脂与牙釉质、牙本质、钛合金、钴铬合金和高含金合金之间的粘接性能的影响。结果表明磷酸二氢(甲基丙烯酰氧癸)酯能够促进复合树脂与牙釉质、牙本质、钛合金、钴铬合金的粘接,剪切强度分别达到13.5、11.2、16.2和18.1 MPa。

10-methacryloyloxydecyl dihydrogen phosphate was synthesized from the reaction of phosphoryl chloride with methylacrylic acid and 1,10-decanediol. The structure of product was characterized by IH-NMR,31P-NMR and MS, The effect of this product on the bond durability of composite resin joined to enamel, dentin and dental alloy was evaluated by the test of shear strengths, 10-methacryloyloxydecyl dihydrogen phosphate significantly elevated the bond strength of the composite resin joined to enamel, dentin, Ti alloy and Co-Cr alloy; the relevant shear strengths were 13.5, 11.2, 16.2 and 18.1 MPa, respectively,
