Abstract
An electronic dental torque wrench is described, including a head with a receiving opening defining a rotation axis and configured to receive a screwing instrument, a shaft defining a shaft axis and configured for applying a torque to the head, wherein the receiving opening is configured to engage with the screwing instrument upon rotation of the shaft around the rotation axis in a tightening direction, wherein the shaft includes a force sensor including one or more force-sensitive resistors and configured to sense the force on the shaft generated upon rotation of the shaft around the rotation axis in a tightening direction, wherein the one or more force-sensitive resistors are arranged at one or more sensor surfaces which are substantially perpendicular to the tightening direction.
