Abstract
Highly filled luting resins are recommended for bonding porcelain restorations to tooth structure. This in vitro investigation was undertaken to determine the degree of cure of a 82 per cent filled dual-curing luting resin, after it was cured through various thicknesses of Cerec Vita Mark II porcelain. Infrared, as well as micro-Raman spectroscopy were used to determine the degree of cure of the cement at different time intervals after mixing and exposure to the curing light. The results indicated that Cerec porcelain thicknesses greater than 3 mm adversely affected the degree of cure of the luting resin, even at 24 hours after mixing the cement.
高填充树脂推荐用于瓷修复体与牙齿结构的粘接。通过不同厚度的Cerec Vita Mark II瓷固化后，进行了82%填充双固化树脂的体外研究，以确定固化程度。利用红外光谱和微拉曼光谱测定水泥混合后不同时间间隔的固化程度。结果表明，Cerec瓷的厚度大于3mm会对树脂的固化程度产生不利影响，即使在混合水泥后24小时也是如此。
