【摘要】：目的:通过研究具有不同植入扭矩(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,并分析IT与ISQ是否相关。方法:将24段牛肋骨随机平均分为水平加力组和垂直加力组,然后将种植体以设定的7种扭矩植入每一段牛肋骨中并测量相应的ISQ值。安放好基台及全瓷冠后,每组分别进行水平向和垂直向加力,记录微动为150um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(P0.05);在同一样本中,IT和ISQ在一定条件下可与种植体初期稳定性相关;IT与ISQ不一定相关。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,IT与ISQ也不一定相关。
[Abstract]:Objective: to study the insertion torque with different insertion torque. ITS and its implant stability quotient ISQs, the ability to fretting under implant resistance. To analyze whether IT and ISQ can reflect the initial stability of implants and whether IT and ISQ are correlated. Methods: 24 segments of bovine ribs were randomly divided into horizontal and vertical reinforcement groups. Then the implant was implanted with 7 kinds of torques and the corresponding ISQ values were measured. After placing the base table and the all-ceramic crown, each group was subjected to horizontal and vertical reinforcement respectively. Results: in each group of samples, IT and ISQ were not related to the initial stability of implants (P 0.05). In the same sample, IT and ISQ could be correlated with the initial stability of implant under certain conditions. Conclusion: it and ISQ reflect that the initial stability of implants is conditional, IT and ISQ do not necessarily reflect the initial stability of implants. It and ISQ are not necessarily related.
