A process and apparatus for treating a tooth. A probing device probes the contours of the tooth while generating signals corresponding to both the position of the probing device and the pressure between the probing device and the tooth so as to generate an accurate indication of the contours of the tooth. A data processing device processes the signals and produces control signals for controlling various tools for machining or otherwise producing orthodontic appliances, particularly crowns. |
