Int J Biomater:HA改性钛表面促进植体抗菌及植骨

2019-07-31 不详 网络

钛基材料广泛用于植入治疗,例如人造牙根。表面处理不仅可以改善生物相容性,而且可以改善表面的化学和机械耐久性,而不会改变金属的机械性能。通过阳极氧化法可以形成相对厚的氧化钛膜。磷酸或硫酸电解质溶液先前已用于阳极氧化。这种阳极氧化膜具有优异的膜硬度,耐磨性和粘合性。在该研究中,使用其中悬浮有氧化钛粉末的硫酸水溶液对钛板进行阳极氧化。形成2800nm厚的氧化钛膜,其比使用磷酸电解质获得的膜厚。将钛板浸入

钛基材料广泛用于植入治疗,例如人造牙根。表面处理不仅可以改善生物相容性,而且可以改善表面的化学和机械耐久性,而不会改变金属的机械性能。通过阳极氧化法可以形成相对厚的氧化钛膜。磷酸或硫酸电解质溶液先前已用于阳极氧化。这种阳极氧化膜具有优异的膜硬度,耐磨性和粘合性。

在该研究中,使用其中悬浮有氧化钛粉末的硫酸水溶液对钛板进行阳极氧化。形成2800nm厚的氧化钛膜,其比使用磷酸电解质获得的膜厚。将钛板浸入模拟体液中1天,评价光催化活性和蛋白质吸附能力,形成均匀的无裂纹羟基磷灰石层。该钛板显示出高亚甲蓝漂白能力。经过上述处理的阳极氧化钛板的酸性蛋白质的吸附能力高。这表明该钛板具有抗菌性和蛋白质吸附能力。

因此,用含有悬浮的TiO2粉末的硫酸电解质水溶液阳极氧化并浸入模拟体液中的钛板可能表现为抗菌和高度生物相容的植入材料。
