The invention also relates to a method for producing a three-dimensional model of at least a partial region of a jaw for producing a dental restoration, comprising the step of: fully-automatic shaping of at least one recess for accommodating a laboratory analogue into the alveolar ridge of the model, whereby the three-dimensional scanning data is used in the shaping and the depth, position, and orientation of the at least one recess are shaped such that the crestal end of the laboratory analogue inserted into said recess coincides with the crestal end of the dental implant in the jaw of the patient or fully-automatic shaping of at least one vestibular, lingual or palatinal feed-through through the model into the at least one recess, whereby 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 with a pin that is inserted through the feed-through in the model into an opening in the laboratory analogue. |
