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150μm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。
Objective：To analyze whether IT and ISQ can reflect dental implants primary stability.Methods：Twenty-four implants were inserted in 24 cow ribs,and the set torque and ISQ values were measured.After abutment and all-ceramic crown were placed,horizontal and vertical force were loaded until the micromotion reached150μm and the force values were recorded.Results：In each group,both IT and ISQ had no significant correlation with implants primary stability（P〉0.05）.While in the same sample,IT and ISQ may have significant correlation with implant＇s primary stability.Conclusion：IT and ISQ can reflect dental implants primary stability under certain condition.
