The proposal is for a process and device for the computer-assisted restoration of teeth. In a first stage of the process the geometry of the tooth to be restored is measured with the aid of a measuring device and electronically stored. In a second stage the tooth image is interpreted, in a third stage the restoring element is constructed using CAD and in a fourth stage the restoring element is ground from a block of suitable material with the aid of a numerically controlled grinder (CAM). According to the invention, the CAD/CAM operation, i.e. stages 2, 3 and part of 4, is transferred to a powerful central computer (13) having the appropriate tools. The computer operates automatically to the greatest possible extent; where necessary it is run by an experienced operator and is connected via a data line (12) to the 3D measuring device (2 and 15, 20) and the grinder (17).
