采用树脂卡环的可摘局部义齿(RPDs)属于非金属卡环义齿(NMCDs)，它可以作为常规金属卡环义齿的另一种选择，弥补美容治疗的需要。

采用树脂卡环的可摘局部义齿(RPDs)属于非金属卡环义齿(NMCDs)，它可以作为常规金属卡环义齿的另一种选择，弥补美容治疗的需要。这篇研究通过面形测定器和动态微型压痕试验来检测抛光对包含E-glass纤维和聚丙烯NMCDs的高强度玻璃纤维加强的热塑塑料(GFRTPs)表面特质的影响，包括：表面粗糙度(Ra)、动态硬度和弹性模量。结果显示，GFRTPs抛光后的Ra值明显低于抛光前。结果接近Ra 0.2的阈值水平，符合义齿基托材料的可接受表面平滑程度。抛光并未显著改变GFRTPs的动态硬度和弹性模量。因为玻璃纤维强化是埋植在聚丙烯基质中，所有负载纤维并没有明显影响GFRTPs的微机械特质。原始出处：Tanimoto Y， Nagakura M.
