<p>The equipment re-bases a dental prostehsis, having a lower plate with a grip for securing and positioning a pattern support, together with the two or more press columns (18, 19) fixed to the plate (3) and joined at the top to a cross-strut (22). A moving component (23) attached to the cross-strut works in a direction parallel to the columns, and acts against a pressure piece (25) bearing onto the prosthesis on the support. Movable locking devices (20a, 20b, 20c) limit the amt. for which the pressure piece can move towards the prosthesis. The moving component can consist of a screw working in a tapped hole in the cross-strut.</p> |
