An Augmented Reality computer model for use in dentistry is implemented using an alpha blending and optic flow analysis software. Recorded patient images or videos are superimposed over the teeth or casts during and/or after the treatment procedure. Improved real time feedback is generated by the system in the presence and absence of the patient. The face bow system enables determination of the hinge axis of the jaw of the patient precise mounting and transfer of dental models to the articulator tracing jaw movements communication of aesthetic parameters of the patient to the dental laboratory and real time design planning or modeling of restorations or prostheses to fit the patient s smile.
