Abstract:
1. A system comprising: a dental handpiece including a handpiece drill; a workpiece guide adapted to be fixed to a dental arch of a patient in a known location in relation to the patient's dentition; a sensor system located on the dental handpiece and including a plurality of moveable mechanical elements, wherein the moveable mechanical elements surround the handpiece drill and contact a known surface of the workpiece guide; an image processor that receives an image of the patient's dentition; a location system that receives data from the sensor system and determines, based at least in part on the data from the sensor system, a depth and an angular orientation of the handpiece drill in relation to the patient's dentition; and a viewer that generates a display image at a computer display such that the generated display image comprises the image of the patient's dentition and a depiction of the depth and angular orientation of the handpiece drill relative to the patient's dentition as determined by the location system; wherein the location system receives updated sensor data and determines based at least in part on the updated sensor data an updated depth and angular orientation of the handpiece drill in relation to the patient's dentition, and the viewer adjusts the generated display image to show the updated depth and angular orientation of the handpiece drill relative to the patient's dentition.
