Int J Mol Sci:I型胶原蛋白修饰钛植体的骨整合效果

2019-02-13 MedSci MedSci原创

牙植入物的骨整合过程的特征在于种植体表面和骨之间界面的愈合现象。已有多种关于植入物表面改性以增加骨整合水平的研究。本研究旨在评估生物功能涂层对牙种植体的影响以及兔模型中的骨愈合反应。通过X射线光电子能谱(XPS),原子力显微镜(AFM),微型CT和组织学分析涂覆有I型胶原的植入物表面。通过X射线光电子能谱(XPS)和原子力显微镜(AFM)分析评估涂覆有I型胶原的喷砂和双酸蚀刻表面,以及未涂覆的喷砂

牙植入物的骨整合过程的特征在于种植体表面和骨之间界面的愈合现象。已有多种关于植入物表面改性以增加骨整合水平的研究。本研究旨在评估生物功能涂层对牙种植体的影响以及兔模型中的骨愈合反应。通过X射线光电子能谱(XPS),原子力显微镜(AFM),微型CT和组织学分析涂覆有I型胶原的植入物表面。

通过X射线光电子能谱(XPS)和原子力显微镜(AFM)分析评估涂覆有I型胶原的喷砂和双酸蚀刻表面,以及未涂覆的喷砂和双酸蚀刻表面,以评估不同的形态。在体内,总共36个植入物植入在兔关节股骨膝关节中,每个表面18个固定器。在15,30和60天进行Micro-CT扫描,组织学和组织形态学分析。

结果显示,在15,30和60天时组织学统计学差异明显(p <0.001)。两个植入物表面都显示出与新形成的骨的紧密相连。成熟骨骼与固定器表面紧密接触。AFM结果显示两种表面的粗糙度相似。

然而,最终结果显示植入物表面上的I型胶原蛋白涂层代表了一种能够改善骨整合的有希望的方法,特别是在骨质量低的区域。
