Definitions
- This invention concerns of a wrench which allows tightening of dental implant screws with the intended torque for all dental implant systems as well as unscrewing several screws.
- This Universal Torque Wrench for Dental Implant Systems consists of a haemostatic like tweezers, in witch the extremities are in the shape of a circle segment, with their inner surfaces corrugated (number 1 in the picture) .
- This wrench is composed of two arms, divided in a handle, a body and an extremity (numbers 3 and 5 in the pictures) .
- One of the arms is rigid in his body and possesses a circular (or similar) ending (number 3 in the picture) .
- To this arm is mounted a dynamometer (number 2 in the picture) which in this case consists of a steel rod. Near the handle of this arm is positioned the scale for the dynamometer (number 4 in the picture) .
- the other arm is semi-rigid in is body (number 5 in the picture) , meaning it has some flexibility, also ending in a circular (or similar) handle.
- Both arms are united by a hinge, located in the body, near the semi-circular extremity. Both arms possess a lock (number 7 in the picture) with several possible positions, witch is located in the body, near the handle.
- the functioning is as follows: when there is a screw to be tightened to a predetermined torque, one grabs the screw connection ( screw driver particular to each dental implant system) and locks it to the Universal Torque Wrench for Dental Implant Systems; next, the driver is delivered to the screw and with a finger leaning on the dynamometer, one tightens the screw by rotating the wrench, until the scale shows the intended torque; finally, one unlocks and removes the Universal Torque Wrench for Dental Implant Systems.
