Accuracy of a manual torque application device for morse-taper implants: a technical note.

Purpose: The objective of this study was to compare torques applied by new and used manual torque devices for Morse-taper implants.

Material And Methods: Fifteen ITI manual torque devices were tested. Those in group 1 (n = 5) were new (ie, never used), those in group 2 (n = 5) had been used 50 to 200 times, and those in group 3 (n = 5) had been used 500 to 1,000 times.
