摘要/Abstract

摘要： 目的：体外比较4种低收缩商品复合树脂及2种传统复合树脂的耐磨性能，探讨影响其耐磨性能的因素，并阐明树脂耐磨性能与材料组成成分的内在关系。方法：选择4种低收缩商品复合树脂CLEARFIL MAJESTY Posterior（CMP）、Filtek LS（LS）、Admira（AD）和Kalore（KA）以及2种传统商品复合树脂Filtek Z350 XT（Z350）、Solitaire2（S2）制成试样，分别置于UMT-2微摩擦磨损试验机上，与氮化硅陶瓷球在蒸馏水环境中进行二体磨损，摩擦14400次，检测试样的摩擦系数和最大磨损深度，扫描电子显微镜（SEM）下观察分析磨损表面形貌。结果：6种复合树脂中CMP磨损深度最小，KA磨损深度最大，由小到大依次为CMP< S2≈LS< Z350≈AD< KA（P<0.05）。SEM观察，Z350、S2、AD和KA表面较为平整光滑，以摩擦磨损和粘着磨损为主，CMP和LS表面较为粗糙，有疲劳磨损特征。结论：复合树脂的耐磨性与填料的性状与含量、填料与基质的结合状况等因素有关。

Abstract: Objective: To investigate the wear resistance of four low-shrinkage commercial composite resins and two traditional composite resins in vitro and discuss the relative influencing factors, and to illustrate the inner relationship of the wear resistance of resins and material composition. Methods: Four low-shrinkage commercial composite resins including CLEARFIL MAJESTY Posterior(CMP), Filtek LS(LS), Admira(AD), Kalore(KA) and two traditional composite resins including Filtek Z350XT (Z350), Solitaire2(S2) were chosen. The bar-shaped specimens were fabricated and mounted in a UMT-2 wear testing machine and abraded with the two-body media (distilled water) with a Si3N4 ball as antagonist.The maximum wear depth was determined after 14 400 cycles. The friction coefficient was determined during the test. The worn surfaces were examined with SEM. Results: CMP showed the lowest maximum wear depth and KA presented the highest maximum wear depth. The maximum wear depth ranked as follows:CMP< S2≈LS< Z350≈AD< KA(P<0.05). The wearing surfaces of Z350, S2, AD and KA were flatter and smoother, showing attrition wear and adhesive wear, whereas the wearing surfaces of CMP and LS were rougher, showing fatigue wear. Conclusion: The wear resistance of composite resins correlated to their type of filler, filler content and filler-resin matrix bonding.

Key words: wear resistance, low-shrinkage composite resin, friction coefficient, maximum wear depth
