A computer station (18) is used to establish in real time, and as a function of the condition and appearance of a jaw bone, the optimum longitudinal axes for drill holes or implants which can be positioned one after another in the jaw bone. Each longitudinal extent in the actual system of coordinates is simulated with the aid of a hand tool (15) which is spatially monitored by means of detection members (16) which transmit, to the computer station, one or more signals which can be related to the position of the tool. The tool (15) is applied to the respective drill hole (3) with an alignment to the jaw bone which corresponds to the longitudinal axis of the future drill hole. With the aid of the contents of the said signals, the computer station simulates the longitudinal axes of the imagined drill holes. The computer presents the drill hole constellation simulated in the actual system of coordinates, and with the aid of the image on the computer screen it is possible to determine whether the simulated constellation is acceptable or not. If accepted, the information is fed back in the form of control signals to the hand tool at the time of the actual production of the drill hole. <IMAGE> |
