There is provided a method that includes (i) transmitting a signal, (ii) receiving (a) a first reflection of the signal from a first reflector on a dental appliance, and (b) a second reflection of the signal from a second reflector on a dental tool, and (iii) determining, from the first reflection and the second reflection, a position of the second reflector relative to the first reflector, thus yielding a relative position of the second reflector. There is also provided a system that performs the method. |
