Articulator for producing dental prostheses

An articulator for parametrizing a prosthetic or occlusal orientation plane and dentoalveolar stages for producing dental prostheses, said articulator comprising an upper planar element and a lower planar element articulated relative to one another about a horizontal axis of articulation (3) parallel to the planes of the elements (1, 2) and located above the lower planar element (2), the upper planar element and the lower planar element configured to simultaneously fasten an upper model of a patient's dental arches under a lower face of the upper element (I) and a lower model (6) of the patient's dental arches on an upper face of the lower element (2), and means for defining, between the upper element and the lower element (1, 2), a plane inclined relative to the upper element (1) and corresponding to an occlusal plane P between the upper model and the lower model, said means for defining corresponding to the occlusal plane P being carried by the upper element (I) and comprising a plate (7) embodying the occlusal orientation plane P;

• and
• wherein the means for defining the occlusal orientation plane P comprise means (8, 9;
• 13;
• 56-59;
• 65-70) for adjusting the angle of inclination and the distance of the plate (7) in relation to the upper element (1) when the upper model is fastened to the upper element and the lower model is fastened to the lower element;
• and
• wherein the adjustment of the distance of the plate (7) in relation to the upper element (1) is performed by at least one first assembly (9) connected to the upper element (1) and a column, said column (8) having graduation (8) and being connected at its lower end to the plate (7) and sliding perpendicularly to the upper element (1) in the first assembly (9) to guide the column (8) and to lock the column in a position adjustable relative to the upper element (1) and
• wherein the adjustment of the angle of inclination of the plate (7) in relation to the upper element (1) is performed by the at least one first assembly (9) connected to the upper element (1) and the column (8), said column (8) carrying at its lower end, a second assembly (13) which carries the plate (7) pivotable about an axis (16) parallel to the axis of articulation (3) between the upper planar element and the lower Planar element.
