Abstract
An articulator for use in making dentures or parts thereof wherein two principal members, pivotable relative to each other by means of conventional condylar mechanisms, have anchoring means for teeth models required for making the dentures. In order for one principal member to carry the other, it has a single, slender arm or post which at its end towards the other member carries the condylar shafts of the condylar mechanisms, with the condylar balls displaceable on said shafts, while the other principal member carries the condylar tracks.
Claims5
In an articulator for use in making dentures or parts thereof, which comprises two principal members (1,2), provided with anchoring means (3) for carrying models of the upper and lower rows of teeth, said members (1,2) being pivotable in relation to each other by means of two condylar mechanisms (10), which simulate the movements of the jaw joint, and one of said members (2) supporting the other (1), for which purpose said one member (2) has a single slender arm or post (11);
- the improvement in which said arm or post (11) at its end toward the other principal member (1) carries condylar shafts (12), that are included in said condylar mechanisms (10), condylar balls (13) which are displacable on said shafts (12), the other said member (1) carrying condylar tracks (14), and said single arm or post (11) having two collinear but oppositely directed apertures (19) at its end toward said other principal member (1), in which apertures (19) said condylar shafts (12) are arranged extending in either direction from said arm or post (11).
