微波加热法及常规水浴法处理聚甲基丙烯酸甲酯基托材料的性能比较研究

A Comparative Study of Mechanical Properties of Microwave cured and Conventional Water Bath cured Denture Base Resins

目的：探讨微波加热法处理聚甲基丙烯酸甲酯（ＰＭＭＡ）基托材料的力学性能。方法：分别采用热水浴法及微波加热法处理的ＰＭＭＡ基托材料，测试其力学性能（抗弯强度、挠度、冲击强度）。结果：微波法可获得与热水浴法处理的基托材料相似，甚至更好的力学性能。结论：经微波处理所获得的ＰＭＭＡ具有能满足临床的力学性能。

Objective:To study the mechanical properties of microwave cured polymethyl methacrylate (PMMA) denture base resins.Methods: Using experiment research, the mechanical properties of microwave cured and water bath cured PMMA materials were compared.Results: The microwave cured acrylic strips had equal or better mechanical properties than conventionally processed strips.Conclusion: The microwave cured denture materials satisfies the requirements of the prosthetic clinic.
