METHODS FOR PRODUCING A LABORATORY ANALOGUE FOR DENTAL IMPLANTS
First Claim
1. A method for producing a laboratory analogue (1, 21, 31) for dental implants comprising the steps of:
- providing at least one sleeve (11) comprising a cylindrical depression (4) having an internal thread;
providing a three-dimensional model (6, 16, 26, 36) of at least a partial region of a jaw of a patient who harbors at least one dental implant;
inserting at least one sleeve (11) into at least one recess (7) of the model (6, 16, 26, 36) matching the sleeve (11), each recess (7) being arranged in a region of the model (6, 16, 26, 36), in which a dental implant is arranged in the jaw of the patient; and
fully-automatic ablation of the at least one inserted sleeve (11), wherein the ablation is controlled through three-dimensional scanning data of an oral space of the patient, wherein the data was recorded previously, and wherein the sleeve (11) is ablated based on such data to the extent that a crestal end of a laboratory analogue (1, 21, 31) produced from the sleeve (11) coincides with a crestal end of the dental implant in the jaw of the patient.

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.

3. A method for producing a three dimensional model (6, 16, 26, 36) of at least a partial region of a jaw for producing a dental restoration, the method comprising the steps of:
-
providing three-dimensional scanning data of an oral space of a patient who harbors at least one dental implant, wherein the data was recorded previously; preparing a three-dimensional model (6, 16, 26, 36) of at least the partial region of the jaw; and fully-automatic shaping of at least one recess (7) for accommodating a laboratory analogue (1, 21, 31) into an alveolar ridge of the model (6, 16, 26, 36), wherein the three-dimensional scanning data is used in the shaping and a depth, a position, and an orientation of the at least one recess (7) are shaped such that a crestal end of the laboratory analogue (1, 21, 31) inserted into the recess (7) coincides with a crestal end of a dental implant in the jaw of the patient. - View Dependent Claims (4, 7, 16, 18)

-
providing three-dimensional scanning data of an oral space of a patient who harbors at least one dental implant, wherein the data was recorded previously; preparing a three-dimensional model (6, 16, 26, 36) of at least a partial region of the jaw with at least one recess (7) for accommodating a laboratory analogue (21) having an opening (25), wherein each recess (7) is arranged in a region of the model (6, 16, 26, 36) in which a dental implant is arranged in the jaw of the patient; and fully-automatic shaping of at least one vestibular, lingual or palatinal feed-through (28) through the model (6, 16, 26, 36) into the at least one recess (7), wherein the three-dimensional scanning data is used in the shaping and the feed-through (28) is arranged such that a crestal end of one laboratory analogue (1, 21, 31) coincides with a crestal end of the dental implant in the jaw of the patient when the laboratory analogue (21) is fixed in place with a pin that is inserted through the feed-through (28) in the model (6, 16, 26, 36) into an opening (25) in the laboratory analogue (1, 21, 31). - View Dependent Claims (6, 17)
