The purpose of this study is to evaluate the relationship between IT and ISQ at implant treatment using the current rough surfaced implant. We evaluated the implant treatment sites with implant stability quotient (ISQ) values, IT values, and voxel values. We assumed that there is relevance between the insertion torque value and the ISQ value.

In all groups, a period of rapidly increasing percentages was observed (8–12 weeks in the low IT group, 4–6 weeks in the medium and high IT groups). In the medium and high IT Group, a statistically significant difference was observed between ISQ ≥ 73 and ISQ < 72 (P < 0.05) : Prospective multicenter non-randomized controlled study on intraosseous stability and healing period for dental implant
