DIN EN ISO 11953 describes a test concerning torque wrenches used for the placement of dental implants. The objective is to verify the repeatability of the torque indication or the triggering accuracy of the torque wrench. The operating principle of torque wrenches may be based on different mechanisms, such as a bending beam with scale indication or a ratchet mechanism that signals the target torque by a clicking sound.

In clinical practice, the key question is how precisely torque values are maintained after repeated use. Using our torque testing system, combined with intermediate endurance testing and reprocessing procedures, we simulate long-term use under accelerated conditions.
