摘要
根据Hosoda提出的分类方法,通过SEM观察和EDX分析,将6种核心树脂根据填充颗粒的元素组成和粒径分布分为两类。此外,还测定了树脂的几种力学性能。结果表明:Bell Feel Core、Clearfil Core、Clearfil PhotoCore、Core Max和Core Max II树脂属于半杂化树脂,Microrest Core树脂属于杂化树脂。EDX在树脂中检测到Si、Zr、Al、Ba和La等元素。树脂的力学性能在固化后1天或1周内表现出高度的稳定性。树脂的机械性能建议后续的冠准备和印模应该推迟到下次预约。
[Classification and several mechanical properties of core composite resins].
According to the classification proposed by Hosoda, six core resins could be divided into two categories on the basis of the elemental composition and size distribution of filler particles by SEM observation and EDX analysis. Furthermore, several mechanical properties of the resins were determined. The following facts were found: Bell Feel Core, Clearfil Core, Clearfil PhotoCore, Core Max, and Core Max II resins were classified as a semihybrid resin, and Microrest Core resin as a hybrid type resin. The elements detected in the resins by the EDX were Si, Zr, Al, Ba and La. The mechanical properties of the resins were shown to be highly stable at one day or one week after curing. The mechanical properties of the resins suggest that the subsequent crown preparation and impression taking should be postponed until the next appointment.
