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.
