Abstract

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.

Abstract

To establish an effective combination of drying time and drying method of the tray adhesive so that maximum bond strength can be achieved between impression tray and impression material.Cylindrical specimens of auto-polymerizing resin and addition silicone impression material were made. A total of 150 specimens were tested. They were divided into two groups Dentsply and GC. Each group was further divided into five subgroups: • Drying with compressed air for half the time as recommended by the manufacturer • Drying with air blower for half the time as recommended by the manufacturer • Open air drying as recommended by the manufacturer • Open air drying for 15 minutes • Open air drying for 1 hour The samples were tested for tensile bond strength using the universal testing machine. The results were subjected to statistical analysis.Open air drying as recommended by the manufacturer was better than drying with a blower or compressed air. There was no significant difference between open-air drying for 5 minutes and open-air drying for 15 minutes or 1 hour.Open air drying as recommended by the manufacturer, i.e. 5min, showed good bond strength and drying for more than 5mins does not significantly increase bond strength.Tray adhesive should not be dried with compressed air or air blower. Tray adhesive should be applied and kept to dry according to the manufacturer's recommended time.
