PURPOSE: This study was to evaluate the accuracy of how to use the Mechanical Torque-Limiting Devices.

MATERIALS AND METHODS: Three different implant manufacturers (Dentium, Osstem, Shinhung) were prepared for each two implant torque controllers. Divided into two groups depending on the method used for removal torque was measured. Repeated measures of ANOVA test (¥á=.05) was used as statistics to evaluate the effect of repeated loading number on the removal torque. Independent t-test was used to evaluate the difference in removal torque of two groups.

RESULTS: The removal torque significantly decreased as the number of loading repetition increased (P<.05). There was significant difference between two groups.

CONCLUSION: Loosen the handle part of the implant torque controllers spring resilience to recover one group compared to the group that did not, showed a little more closed to the reference value.
