Abstract: 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 reached 150μm 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.
