Research into improved adhesion of resins to tooth substrates has found that methacrylates with both hydrophobic and hydrophilic groups, like 4-methacryloxyethyl trimellitate anhydride (4-META), enhance monomer penetration into dentin pretreated with 10% citric acid and 3% ferric chloride (10-3). Scanning and transmission electron microscope (SEM and TEM) examinations revealed the formation of a transitional zone of resin-reinforced dentin, termed the hybrid layer. The 4-META adhesive resin impregnated the exposed collagen bundles with which it entangled to create the hybrid, essential to attaining high tensile bond strengths.
对改善树脂与牙齿基质附着力的研究发现，具有疏水和亲水基团的甲基丙烯酸酯，如偏苯三酸三缩水甘油酯甲基丙烯酸酯（4-META），可增强单体渗透到经10%柠檬酸和3%氯化铁预处理的牙本质中（10-3）。扫描电子显微镜和透射电子显微镜（SEM和TEM）检查显示形成了树脂增强牙本质的过渡区，称为混合层。4-META粘结树脂浸渍暴露的胶原束并与之缠结形成混合层，这对于获得高拉伸粘结强度至关重要。
