Objective:
This study aims to evaluate the effects of two drill designs on insertion torque (IT) and implant stability quotient (ISQ) during osteotomy.
Methodology:
This in vivo animal study involved eight female New Zealand white rabbits divided into two groups: Group A underwent osteotomy using standard drills from the Zimmer surgical kit, and Group B used Densah drills. IT values and ISQ were taken during and after implant placement. Rabbits received premedication, and postoperative care was provided.
Results:
Significant differences in peak IT were observed between the two groups, with Group B demonstrating a statistically significant advantage. However, no significant differences were found in ISQ between the groups.
Conclusion:
This study highlights the potential benefits of osseodensification in enhancing primary stability during osteotomy.
