Provided herein, inter alia, is a system for indicating the location of a dental drill includes a dental handpiece, which further includes the dental drill. A plurality of sensors detect a magnetic field and produce a set of outputs, which are usable at least in part to indicate the location of the dental drill. The sensor outputs may be processed to produce an indication of the spatial relationship of the drill to a patient's dentition. The indication is preferably graphical, and may be presented to a dental professional using the system during an implant procedure to provide visual feedback about the procedure. The indication may be repeatedly updated, substantially in real time. |
