Five types of light-cured direct bonding adhesives with different volumes of microfiller were prepared for study of the relationships between bond strength to enamel, resinous tag length, and flexural strength, and between viscosity and resinous tag length. The resinous tag length was measured with the combination of 2,4,6-trichlorophenoxy methacrylate as a tracer and electron-probe microanalyzer. Correlating resinous tag length versus viscosity or bond strength after 1-day immersion, and flexural strength with bond strength after 1-day and 30-day immersion resulted in high correlation coefficients. However, the bond strength after thermocycling did not correlate with resinous tag length or flexural strength.
制备了五种含有不同微填料体积的光固化直接粘结剂,用于研究与牙釉质的粘结强度、树脂突长度和弯曲强度之间的关系,以及粘度与树脂突长度之间的关系。采用2,4,6-三氯苯氧基甲基丙烯酸酯作为示踪剂与电子探针微分析仪相结合的方法测量树脂突长度。将1天浸泡后的树脂突长度与粘度或粘结强度以及1天和30天浸泡后的弯曲强度与粘结强度进行相关性分析,得到了较高的相关系数。然而,热循环后的粘结强度与树脂突长度或弯曲强度无关。
