Abstract
A dental torque ratchet head and driver handle (8) is formed with a chamber (12a) between first (30) and second (32) pivotably mounted handle members which receives a plastic insert (14) formed in a configuration selected so that the insert fractures at a selected torque to thereby ensure the application of a precalibrated level or torque to an abutment or prosthetic screw of an implant. A solid metal insert (14') can be used to convert the tool to a straight ratchet tool.
