ABSTRACT:
The invention relates to a dental articulator in which the support table for the front tooth guide pin is disposed on the upper frame part and the adjustable front tooth guide pin is disposed on the lower frame part. The table plate of the support table is preferably divided into two regions, of which one region, which provides the central support, remains invariably in the horizontal position, while the other region, in which the excursions of the front tooth guide pin take place, is pivotable downwards at the front relative to the transverse axis of the articulator and can be locked in any desired inclined position. In addition, the support table is preferably arranged rotatably in the plane of its base surface, in order to be able to determine better the progression of the guide surfaces of the different teeth when a lateral movement is made. On the upper portion of the upper frame part there is preferably disposed a support device which ensures secure support when the articulator is laid down on its back and also when only the upper frame part is laid down on its back.
