Abstract: A dental articulator includes an articulator frame. The articulator frame has an upper member adapted to hold an upper mounting plate. The upper mounting plate holds an upper dental cast. An elongate lower member of the frame holds a lower mounting plate. The lower mounting plate holds a lower dental cast. The upper member is pivotally connected to the lower member so as to define an anatomically accurate hinge axis to simulate human jaw movement. The dental articulator can be used to form dental prostheses.

Abstract: A face bow assembly including a face bow having a bite fork portion to carry an index trays to be positioned in a patient's mouth. The bow has outwardly extending wings to enable a dentist to support the bow. A vertical indicator rod mounted to the bow helps align the tray horizontally and the indicator rod vertically to the patient's mid-sagittal, while bite impression material on the tray hardens. The upper index tray is then mounted on a platform on a dental articulator. The platform has an incisal line for alignment with an incisal line(s) for adjustability on the upper index tray. The platform also has vertical or horizontal adjustability with a built-in scale.

Abstract: The disclosed waxing guide is in the form of a thin flat element having a central line formed thereon. The guide is placed beneath the dental cast with the central line centered between maxillary central incisors on the dental cast. Lines spaced outwardly from the central line indicate the apparent width of the central incisor, the adjacent lateral incisor, and the adjacent canine tooth and first bicuspid, when viewed from the front. Each of the spaces has the same ratio of 1:1.618 with the adjacent spaces.
