For producing dentures, a new method and device render it possible to evaluate and shape movements generated by the individual jaw joints of the patient such that work with appropriate articulators becomes possible, which employ the individual jaw joints as articulation joints and thus carry out the identical movements. The known articulators are equipped with joint-space duplicates such that they can be employed with optimal equipment for the respective patient. The support pin is moved back as fixing pin in the retral space of the articulator such that it does not constitute an impediment when working on and when inspecting the jaw models arranged on the frame upper part and the frame base part. Moreover, setting different biting positions is made significantly easier, because the frame upper part is fixed to a swivel arch of the frame base part by an adjustable position stabilizer but can also be detached.
A method for producing a dental prosthesis, in which first an impression of an upper jaw and of a lower jaw with teeth is made, and a device designated as an articulator for simulating jaw movements on dental bite registration molds, which register the corresponding upper and lower jaw impressions, is then taken to a dental technician, whereupon the dental prosthesis is molded by moving either the lower jaw impression or the upper jaw impression around articulator joints that are similar to the patient's jaw joints and are produced taking into account the lower jaw impression, then returned to the dentist, inserted in the patient, and finished by the dentist, wherein before or after the impressions of the upper and lower jaw are produced, the movement paths in the basic directions of the patient's jaw joints when the lower jaw is moved are determined, registered and used as articulator joints on the articulator for the production representation of the joint space duplicates of the patient's jaw joints, and in that this articulator equipped with articulator joints corresponding to the patient's jaw joints is then used by the dental technician to restore the dental prosthesis, wherein the movements performed by the patient's lower jaw are guided by a support pin, which is firmly held in the upper jaw via an upper jaw plate, and transferred via hemispheres allocated to a lower jaw plate, which are arranged spaced apart from each other and forming a triangle with the support pin in the support pin/jaw joint axis, while decoupling the patient's prosthesis, as a joint space duplicate in a plastic material embedded in dental bite registration mold allocated to the upper jaw plate, and further joint space duplicates of each jaw joint are manufactured using these joint space duplicates extraorally according to the pantograph principle, and used as an articulator joint in the articulator.
A method for producing a dental prosthesis, in which first an impression of an upper jaw and of a lower jaw with teeth is made, and a device designated as an articulator for simulating jaw movements on dental bite registration molds, which register the corresponding upper and lower jaw impressions, is then taken to a dental technician, whereupon the dental prosthesis is molded by moving either the lower jaw impression or the upper jaw impression around articulator joints that are similar to the patient's jaw joints and are produced taking into account the lower jaw impression, then returned to the dentist, inserted in the patient, and finished by the dentist, wherein before or after the impressions of the upper and lower jaw are produced, the movement paths in the basic directions of the patient's jaw joints when the lower jaw is moved are determined, registered and used to form articulator joints on the articulator for the production representation of the joint space duplicates of the patient's jaw joints, and in that this articulator equipped with articulator joints corresponding to the patient's jaw joints is then used by the dental technician to restore the dental prosthesis, wherein the values obtained during the articulation, when jaw joint fossa is delineated, are additionally or only electronically registered, stored and used via CadCam to form joint movement spaces in the template in a dental bite registration mold or directly for joint space duplicates.
