Abstract: A universal articulator for prosthodontic use includes upper and lower frames with respective horizontal branches. The rear end of the upper frame has inclined wings with slots. The front end of the lower frame has an incisal tray that is inclined. An incisal pin extends from the incisal tray to the upper frame. Articulator pins extend from the lower frame into the upper frame slots. The articulator pins are in different length pairs and the incisal pins are of different lengths and the pins are substituted for accomplishing adjustable spacing between the horizontal branches of the upper and lower frames which are held parallel and horizontal. A dental plaster supporting dental plate is removably supportable on and removable from one or each of the branches by an attachment element easily removed. Alternatively, dental plaster supporting retaining pins extend across the frames.

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.
