Method for articulator adjustment and gnathological instruments for work under this method
Patent No. 9,517,116
Issued: December 13, 2016
Inventor: Filtchev; Andon Dimitrov (Sofia, Bulgaria)
The method for articulator adjustment and gnathological instruments for work under this method find application in dental medicine and laboratory dental techniques. These and other goals of this invention are achieved with the measurement of the individual parameters of the patient's mandibular transversal hinge axis in the three planes: transversal, frontal and sagittal, including the following steps: measurement of inter-condylar distance; measurement of the distance between the condylar axis and the occlusal plane; measurement of the distance between the condylar axis and central incisors with a face-bow and bite-tray (FIGS. 1,10,11,12); recording of values; simultaneous fixation in the articulator in minimal gathered position of the manufactured in advance two primary working models juxtaposed in central position: a mandibular lower working model to the working plate of the lower articulator frame and a maxillary upper working model to the opposite working plate, which is connected in a telescopic way to the upper articulator frame (FIGS. 2,3,4,5,6,13); coincidence of the mandibular transversal hinge axis of a patient in terms of measured values of his individual parameters and the articulator transversal hinge axis (FIGS. 7,8,9,14); and closure of this articulator in an individual spread-out position.
