Dental torque wrench

A torque wrench as a ratchet instrument for medical technology having a head region which has a receptacle opening, a neck region which adjoins the head region, a bar-shaped activation lever which, for applying a torque to the head region, is fastened to the neck region and extends at least approximately in one plane, a bezel which forms the receptacle opening of the head region and defines a rotation axis that runs so as to be at least approximately orthogonal to the plane and is specified for receiving a driver instrument in the extent of the rotation axis, a spring bracket and a latching cam which is configured on the spring bracket and in the resting position of said latching cam protrudes into the receptacle opening, the entrainment portion of the latching cam when the driver instrument is inserted in the receptacle opening, and when the activation lever is rotated in the tightening direction in an entraining position of the latching cam, being specified for interacting with a mating face of the driver instrument so as to by way of entrainment transmit a torque to the driver instrument, the latching cam, when rotating counter to the tightening direction, being specified for moving counter to the force of the spring bracket to a releasing position, so as to form a freewheeling mechanism between the head region and the driver instrument, wherein the bezel has a cutout running across the entire cross section of the latter and forms the spring bracket.
