Abstract
A method for producing a three-dimensional model of a region of a jaw for producing a dental restoration includes fully-automatic shaping of a recess for accommodating a laboratory analogue into the alveolar ridge of the model. Three-dimensional scanning data is used in the shaping and the depth, position, and orientation of the recess are shaped such that the crestal end of the laboratory analogue inserted into the recess coincides with the crestal end of the dental implant in the jaw of a patient. The method may also include fully-automatic shaping of a vestibular, lingual or palatinal feed-through through the model into the recess, wherein the three-dimensional scanning data are used in the shaping and the feed-through is arranged such that the crestal end of a laboratory analogue coincides with the crestal end of the dental implant in the jaw of the patient, when the laboratory analogue is fixed in place.
