<p>The machine is for producing dental prostheses in which are plates (24,44) for fitting lower jaw and upper jaw prostheses. The one plate (24) is fitted to a column frmed by pieces (17,23,31) driven by controls (21,29) pivoting and turning in all directions, the assembly remaining attached to the fixed baes (1) which incorporates displaceable blocks (5,12) activated by controls (8,13). The prosthesis of the upper jaw remains suspended, sustained by the column formed by bodies (49,52) driven by controls (33,57) for its pivoting and coupling, supported by the bar (48) and the arm (37), both fitted on the vertical column (36), its height being regulated by means of the upper drive (39) and its threaded shaft (41).</p> |
