J Oral Rehabil:机械清洗钛或氧化锆表面后表面变化对上皮组织附着的影响

2020-02-15 不详 网络

机械去除菌斑可能会改变植入物穿透牙龈部分的表面形态。我们使用气动磨料系统(AP),钛刮匙(TC),不锈钢刮匙(SC),超声洁牙机(US)和钛刷(TB)处理钛或氧化锆,探究植体表面形态的变化和上皮对基底的附着。(1)通过扫描电子显微镜和粗糙度分析仪评估机械清洗后钛和氧化锆的形貌变化。(2)机械清洗后,将大鼠的口腔上皮细胞接种在材料的表面上,观察上皮细胞的粘附。(3)从大鼠中提取上颌第一磨牙,并用实验

机械去除菌斑可能会改变植入物穿透牙龈部分的表面形态。我们使用气动磨料系统(AP),钛刮匙(TC),不锈钢刮匙(SC),超声洁牙机(US)和钛刷(TB)处理钛或氧化锆,探究植体表面形态的变化和上皮对基底的附着。

(1)通过扫描电子显微镜和粗糙度分析仪评估机械清洗后钛和氧化锆的形貌变化。(2)机械清洗后,将大鼠的口腔上皮细胞接种在材料的表面上,观察上皮细胞的粘附。(3)从大鼠中提取上颌第一磨牙,并用实验性钛或氧化锆植入物代替。在植入物-植入物-植入物上皮界面观察到了免疫反应性层粘连蛋白-332带的长度。

结果显示,(1)除AP组外,实验组的植体表面粗糙度均增加。(2)实验组中,AP组贴壁细胞数量最多。(3)对照组中免疫反应性层粘连蛋白-332条带的长度比所有五个实验组的更长。在实验组中,AP组显示出最长的条带。

综上所述,该研究结果表明,除AP外,所有机械清洁方法都会增加材料的表面粗糙度。AP没有引起明显的植入物表面改变。机械清洁引起的表面变化可能使上皮附着不佳,并降低了抵抗外来渗透的能力。
