ProTaperNext锉和WaveOne锉根管成形能力的对比研究
|
Abstract:
摘要 目的:比较机用ProTaperNext和WaveOne在弯曲树脂模拟根管中的成形能力。方法:选取统一规格的透明树脂模拟根管40个,将其随机分为2组,分别使用ProTaperNext和WaveOne锉以冠向下技术预备两组树脂模拟根管。使用ImagePro Plus软件测量根管弯曲半径和弯曲度的变化以及各测量点去除树脂量,计算树脂去除总量和两组器械的中心定位力,同时记录和分析根管工作长度的变化和器械变形、分离等参数。结果:两种器械预备根管时,均能保持较好的工作长度,不易发生器械分离,能够较好的维持根管原始走形,但在根尖段,WaveOne预备后的根管较易发生偏移。结论:ProTaperNext与WaveOne相比,在预备重度弯曲根管时具有良好的根管成形能力
