摘要： An orthodontic driver tip according to the invention is configured for screwing and unscrewing an orthodontic bone screw. Such a driver tip includes an elongated inner rod having an enlarged diameter front tip portion with a frontwardly opening recess, which tip portion comprises at least two frontwardly extending resilient arms which define the frontwardly opening recess between them, and a rear connecting portion by which the driver tip can be removably secured to a handle. A sleeve is mounted on the rod rearwardly of the enlarged diameter front tip portion, the sleeve having a front end of lesser diameter than a maximum diameter of the arms of the tip portion. A locking mechanism releasably secures the sleeve against lengthwise movement along the rod when the sleeve is moved forward to a position wherein the arms are bent into engagement with the head of a bone screw disposed inside the front tip portion.
