The aim of this study was to evaluate the tensile properties and water absorption of denture base material prepared from high molecular weight poly methyl methacrylate (PMMA) and alumina (Al2O3) as particulate filler. Specimens for mechanical testing were prepared by adding composite powder to the monomer followed by hand mixing as in dental laboratory procedure. The tensile strength of the prepared denture base material was slightly higher than commercial denture base material, while the water absorption was almost the same for all formulation of denture base materials.
本研究的目的是评估由高分子量聚甲基丙烯酸甲酯（PMMA）和作为颗粒填料的氧化铝（Al2O3）制备的义齿基托材料的拉伸性能和吸水性。按照牙科实验室程序，通过将复合粉末添加到单体中然后手工混合来制备用于机械测试的试样。所制备的义齿基托材料的拉伸强度略高于市售义齿基托材料，而所有义齿基托材料配方的吸水性几乎相同。
