| ■ Speing Based Torque Wrenches |
| |
---The instrument automatically disengages when a present torque value is reached.
The accuracy of spring based wrenches is dependent upon the manufacturer’s calibration which changes over time due to spring fatigue. The clinician can never be certain that he is applying consistent torque forces. They require multiple wrenches or snap-on fiftings for different torque values and periodic recalibration to maintain even limited accuracy. Torque-LockTM does not rely on a spring for its accuracy. One wrench reads values between 10Ncm and 50Ncm. |

| ■ Digital Motor-Driven Torque Devices |
| |
---Torque is applied via contra-angle handpiece with values registered on the motor’s gauge
These torque devices are expensive, cumbersome and convenient for use. They require thorough cleaning and maintenance. The friction created by numerous metal internal parts degrades their operational accuracy. Torque-LockTM is affordable, lightweight and ergonomically designed. Jeweled surfaces significantly reduce friction. |

| ■ Plastic Insert Torque Wrenches |
| |
---When a preset torque value is reached a disposable plastic insert breaks.
Accuracy and function is dependent upon disposable plastic inserts that must be replaced ahter each use. Every time the wrench is used an expense is incurred. These wrenches have no gauge and can only determine preset torque values. Torque-Lock ’s self-contained design requires no additional inster costs. |
