摘要: 复合树脂固化时发生聚合收缩,可能会导致最终修复失败或引起其他并发症。应用显微CT(micro computed tomography,micro CT)可以测量树脂聚合前后的体积变化及由此导致的微渗漏,并可通过示踪颗粒测量树脂聚合收缩矢量,以得到精确的收缩变化的相关数据。这种检测技术无创伤,立体直观,更精确、科学,该文就该技术进行综述。

Abstract: The shrinkage of composite restorations upon polymerization may lead to clinical failures and adverse consequences. Microcomputed tomography (microCT) can be used to measure the volume change before and after polymerization of the resin and the resulting microleakage; on the other hand, shrinkage vector can be calculated through tracing particles. This method is nondestructive, threedimensional visual, more accurate, and more scientific. This article reviewed the technology.
