Acta Biomater:二氧化铈种植体表面改性解决临床种植体周围炎的发生

2019-06-20 sunshine medics

种植体周围炎是牙种植体失效的最常见风险因素。纳米结构的二氧化铈(纳米CeO2)具有抗炎和抗菌功能,由特定晶面包围的不同形状的二氧化铈可以是增强内在催化作用的有效方法。在本研究中,作者开发了一种新的种植体表面改性策略,通过在钛(Ti)表面涂覆不同形状的纳米CeO2来增强其抗菌和抗炎特性。该研究旨在:(1)开发用不同形状的纳米CeO2(纳米棒,纳米立方体和纳米八面体)改性的新型钛表面,用于预防种植体周

种植体周围炎是牙种植体失效的最常见风险因素。纳米结构的二氧化铈(纳米CeO2)具有抗炎和抗菌功能,由特定晶面包围的不同形状的二氧化铈可以是增强内在催化作用的有效方法。在本研究中,作者开发了一种新的种植体表面改性策略,通过在钛(Ti)表面涂覆不同形状的纳米CeO2来增强其抗菌和抗炎特性。该研究旨在:(1)开发用不同形状的纳米CeO2(纳米棒,纳米立方体和纳米八面体)改性的新型钛表面,用于预防种植体周围炎; (2)研究和比较不同形状的CeO2修饰表面对种植体周围炎相关病原体生物膜的抑制效果; (3)评价不同CeO2修饰的表面对体外和体内细胞炎症反应的影响。

结果表明,与其他CeO2修饰的Ti相比,纳米棒CeO2修饰的Ti在早期具有更多的血链球菌附着细菌(p <0.05)。都显示出与种植体周围炎相关的生物膜相似的大量CFU减少(p> 0.1)。纳米立方体和纳米八面体CeO2修饰的Ti在体外比纳米棒CeO2具有更好的抗炎作用和ROS清除能力(p <0.05)。在体内,三种形状的纳米CeO2降低了Ti周围组织中TNF-α,IL-6和IL-1β的平均mRNA表达;纳米八面体CeO2在所有组中表现出最强的抗炎作用(p <0.05)。总之,所有三种类型的CeO2改性Ti都具有同样强的抗菌性能;纳米八面体CeO2改性的Ti具有最佳的抗炎作用。

因此,CeO 2改性的Ti表面非常有希望增强牙科植入物的抗微生物功能。Ti上新型纳米八面体CeO2涂层具有减轻和消除种植体周围炎的巨大治疗潜力。
