ABSTRACT:
The articulator is the type which has an upper part with a horizontal branch and a lower part with a horizontal branch below and substantially parallel to the upper branch. The upper part has a pair of spaced wings connected to the rear of the upper branch and angling upwardly at a small angle therefrom as well as an adjustable incisor pin extending downwardly from the front end thereof. The lower branch has a pair of spaced articulator pins extending upwardly into slots in the wings of the upper part as well as an incisal tray angling downwardly from the front end to receive the incisal pin. Thus the upper part is supported in the lower part as a tripod with a relatively low center of gravity. A mold is provided to be connected to the articulator.
