Abstract

Composites with Nano fillers reinforced by polymer structures are gaining popularity in the field of prosthodontic. Composite materials are being developed to meet the needs of patients, such as heat cure acrylic resins, that used so much in the field of prosthodontic. To evaluate the flexure strength of heat-cure acrylic resin reinforcement with Nano aluminum oxide (Al2O3) after polishing with various abrasive materials. A total of seventy rectangular specimens of heat cure acrylic resin with dimensions (65 mm length x 10 mm diameter x 3 mm thickness) Samples were separated into main seven groups classifications based on the addition of Nano Al2O3 and surface’s polishing with different abrasive materials. Each group have (10) specimens. The highest mean value of flexure strength was obtained in group (B) (87, while the lowest value was obtained in group (F) (56.9). It concluded that the flexure strength was decreased in groups (F and G) of heat-cured resin polished with diamond, while it was increased in groups (B and C) polished with pumice, followed by the control group(A), and then by groups (D and E) that polished with colloidal.

不同磨料抛光后纳米Al2O3热固化丙烯酸树脂增强材料的抗弯强度评价

高分子结构增强纳米填料复合材料在口腔修复领域的应用越来越广泛。为了满足患者的需要，正在开发复合材料，如热固化丙烯酸树脂，在修复领域使用得很多。评价纳米氧化铝(Al2O3)热固化丙烯酸树脂增强材料经各种磨料抛光后的抗弯强度。采用尺寸为长65 mm、直径10 mm、厚度3 mm的矩形热固化丙烯酸树脂试样70个，根据纳米Al2O3的添加量和不同磨料对表面的抛光情况，将样品分为7大类。每组有10个标本。挠曲强度平均值(B)组最高(87)，平均值(F)组最低(56.9)。结果表明:金刚石抛光热固化树脂的抗折强度降低，浮石抛光热固化树脂的抗折强度升高，浮石抛光热固化树脂的抗折强度升高，其次是对照组(A)，胶体抛光热固化树脂的抗折强度升高。
