METHODS FOR PRODUCING A LABORATORY ANALOGUE FOR DENTAL IMPLANTS

摘要

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.

1. A method for producing a laboratory analogue for dental implants, said method comprising the steps of:
providing at least one sleeve comprising a cylindrical depression having an internal thread; providing a three-dimensional model of at least a partial region of a jaw of a patient who harbors at least one dental implant; inserting at least one sleeve into at least one recess of the model matching the sleeve, each recess being arranged in a region of the model, in which a dental implant is arranged in the jaw of the patient; and fully-automatic ablation of the at least one inserted sleeve, 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 is ablated based on such data to the extent that a crestal end of a laboratory analogue produced from the sleeve coincides with a crestal end of the dental implant in the jaw of the patient.
