摘要： The invention relates to a method for the computer-controlled production of dentures for restoring at least one tooth or jaw area, especially in terms of occlusal or incisal contact. The aim of the invention is to provide a simple means of producing dentures using CAD/CAM techniques, at the same time ensuring that the contact surfaces of the denture have the individual shape required so that absolutely no subsequent work is necessary. To this end, the inventive method comprises the following steps: forming an impression of the upper and lower jaw in order to produce casts of the same and co-ordinating them using an articulator; coordinating at least two points of reference on the upper jaw cast or the lower jaw cast or other selected points of reference with the axis of rotation of the articulator or with at least two points of reference allocated to the same, arranging the upper jaw cast and the lower jaw cast in a measuring device for determining the geometry of the tooth, jaw or jaw area being restored, the two points of reference being arranged in a predetermined position in relation to the system of co-ordinates of the measuring device in order to produce a virtual representation of the axis of rotation of the articulator or the at least two points of reference allocated to the same; digitising the upper and lower jaw casts; constructing the denture using CAD and manufacturing the denture using CAM.
