以双酚A双甲基丙烯酸缩水甘油酯(Bis-GMA)为树脂基质，分别加入三乙二醇二甲基丙烯酸酯(TEDMA)和甲基丙烯酸羟乙酯(HEMA)为辅助单体，以纳米二氧化硅为无机填料，通过共混合原位聚合分别制备了两种复合树脂粘结剂：粘结剂A为Bis-GMA与TEDMA的交联共聚物与纳米二氧化硅的复合树脂，粘结剂B为Bis-GMA与HEMA的交联共聚物与纳米二氧化硅的复合树脂. 用这两种粘结剂将纤维桩与牙根粘结，并研究了温度与机械疲劳对这两种粘结剂的剪切粘结强度的影响.

Two composite resin bonders were prepared via in-situ polymerization and blending method using Bis-GMA as resin matrix and nano-SiO2 as inorganic filler. Composite resin bonder A was composed of crosslinked copolymer of Bis-GMA/TEDMA and nano-SiO2, and composite resin bonder B contained crosslinked copolymer of Bis-GMA/HEMA and nano-SiO2. Both composite resins were employed as luting agent to bond fiber posts into root canals and the effects of temperature fatigue and mechanical fatigue on their shear bonding strength were studied.

Key words: bis-GMA, composite resin, inorganic filler, shear bond strength
