IT与ISQ能反映种植体初期稳定性吗
|
Abstract:
摘要 目的:研究不同植入扭矩(insertion torque,IT)及其种植体稳定系数(implant stability quotient,ISQ )值的种植体抵抗力作用下微动的能力,分析IT与ISQ能否反映种植体初期稳定性。方法:将24颗种植体以设定扭矩植入牛肋骨中并测量相应的ISQ值。安放好基台及全瓷冠后,进行水平向及垂直向加力,记录微动150 μm时的力。结果:在每组样本中,IT和ISQ均与种植体初期稳定性不相关(P＞0.05);在同一样本中,IT和ISQ可与种植体初期稳定性相关。 结论:IT与ISQ反映种植体初期稳定性是有条件的;IT与ISQ不一定能反映种植体初期稳定性
