1吸水对充填复合树脂抗弯性能的影响显示文摘目的研究吸水对充填复合树脂抗弯强度和弹性模量的影响。方法将混合型前牙充填复合树脂(GDA)和通用型充填复合树脂(GCK)根据ISO FDIS 4049:1999标准制备为大小(25±2)mm×(2±0.1)mm×(2±0.1)mm的柱状试件,分为GDA1,GDA30,GDA90,GDA150,GCK1,GCK30,GCK90,GCK150共8组,每组13个样本。分别放入(37±1)oC的去离子水中浸泡1天、30天、90天、150天。利用三点弯曲实验测量并计算试件的三点抗弯强度和挠曲弹性模量。在体视显微镜和扫描电子显微镜下观察断面形貌。结果 GDA30和GCK30组分别与GDA1和GCK1组相比,抗弯强度的差异均无统计学意义。GDA90及GDA150组的抗弯强度随浸水时间延长而逐渐降低,差异具有统计学意义;GCK90及GCK150组与GCK1组抗弯强度的差异具有统计学意义,但GCK90及GCK150组之间抗弯强度的差异无统计学意义。GDA及GCK不同浸水时间的各组之间,其弹性模量的差异无统计学意义。结论在浸水150天的有限时间内,吸水会使充填复合树脂GDA和GCK的抗弯强度降低,但不会影响其弹性模量。魏永杰 张振庭 Nick Silikas David C.Watts 2016北京口腔医学2016,24,3:4
2IPS-Empress 2玻璃陶瓷结构及性能的研究显示文摘目的 研究新型IPS Empress2牙科高强度陶瓷的显微结构和机械性能。方法 采用原子力显微镜、扫描电子显微镜和X射线衍射仪,分析IPS Empress2的显微结构和晶相,用三点弯曲实验和压痕法测试其弯曲强度和断裂韧性。结果 IPS Empress2玻璃陶瓷主要由二硅酸锂晶体和磷酸锂晶体组成,二者形成相互交错的三维网络式结构;这种玻璃陶瓷在热压铸前后晶体相保持不变,其三点弯曲强度和断裂韧性分别为 300MPa和 3 1MPam1 /2。结论 IPS Empress2玻璃陶瓷的高强度和韧性与高含量的二硅酸锂晶体、相互锁结的网络结构和裂纹偏转有关。骆小平 D.CWatts N.H.FWilson N Silikas 陈亚琴 2005中华口腔医学杂志2005,40,2:2
