ABSTRACT:
A method and apparatus for accurately photographically recording three-dimensional models of dental arch profiles in a plurality of photographic views taken in centric occlusion and in apposition. The method involves photographing such models in centric occlusion in a plurality of views obtained by rotating the model about an axis normal to the occlusal reference plane and lying in the mid-saggital plane substantially 15 mm. posterior of the inter-canine line. The apparatus comprises a supporting bench bearing a mounting platform for the model and a camera holder spaced from one another by a predetermined substantially constant distance. Means are further provided for rotating the mounting platform to facilitate exposure of the model in a plurality of views in centric occlusion, together with means for adjusting the location of the camera holder in the three mutually perpendicular directions, axially along the bench relative to the mounting platform, transversely across the longitudinal axis of the bench, and vertically of the mounting platform.
