  • Patent number: 10945822
    Abstract: Method for producing a three-dimensional model of at least a partial jaw comprising: fully-automatic shaping of at least one recess for accommodating a laboratory analogue into the alveolar ridge of the model using three-dimensional scanning data and shaping the depth, position, and orientation of the at least one recess 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; or fully-automatic shaping of at least one vestibular, lingual or palatinal feed-through through the model into the at least one recess using three-dimensional scanning data and arranging the feed-through such that the crestal end of a laboratory analogue coincides with the crestal end of the dental implant in the jaw when the laboratory analogue is fixed in place with a pin inserted through the feed-through in the model into an opening in the laboratory analogue.

  • Publication number: 20200368116
    Abstract: The invention relates to a dental ceramic blank, in particular a filled milling blank, comprising at least one organic Compound, such as a polymer polymerized in the blank, for improving the machining properties of the blank. The blank has an open-pore ceramic microstructure which has 2 to 50 wt. %, based on the total composition of the dental ceramic blank, of at least one organic Compound. The invention also relates to a method for producing the blank.

  • Publication number: 20130330689
    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.
