Abstract: A jaw movement recording device, articulator and methods disclosed utilize a lower marking plate with front, rear, left and right side marking pins that cooperate with an upper marking plate and depressions and a bearing pin in such a way as to give an accurate recording of the movement of a patient's lower jaw in a wafer between the two plates. An articulator has a lower frame with upright side posts having upper pin-like portions and an upper frame with fossa holders and a pliable material that form fossa socket patterns. Tension springs extending between the frames at the front and rear enable a constant tension in forming the fossa socket patterns.
