A study on the composition of the resin component of the several brands of composite resin has not been published so far. It was the purpose of the present work to fill out this gap in our knowledge of this important group of restorative materials by analyzing the monomers of the materials as delivered by the manufacturers. 24 brands of restorative resins were investigated by means of a Nuclear Magnetic Resonance spectrometer at 90 MHz. Spectra were taken of deuterated chloroform solutions of the organic part of the filling materials and compared with spectra of pure monomers that were conceivable constituents of the investigated brands. It was found that the BIS-GMA containing brands all contain at least one other monomer, most often TEDMA, in varying concentrations. The brands with MMA as main component in most cases also contain other monomers.
迄今为止,尚未发表关于几种品牌复合树脂树脂成分组成的研究。本研究的目的是通过分析制造商提供的材料中的单体,填补我们对这一重要修复材料组认识上的空白。通过一台90兆赫的核磁共振光谱仪对24种品牌的修复树脂进行了研究。对填充材料有机部分的氘代氯仿溶液进行光谱分析,并与所研究品牌可能含有的纯单体光谱进行比较。结果发现,含双酚A-甲基丙烯酸缩水甘油酯(BIS-GMA)的品牌均含有至少一种其他单体,最常见的是三乙二醇二甲基丙烯酸酯(TEDMA),其浓度各不相同。大多数情况下,以甲基丙烯酸甲酯(MMA)为主要成分的品牌也含有其他单体。
