Abstract
An impression film, adapted to intraorally record an occlusal position at virtually unaltered vertical and horizontal dimensions, is matched to a light source and a photographic film such that micron changes in the thickness of the impression film can result in photographically measurable changes in the percent transmission of light from the light source through the impression film. In this manner, an occlusal position can be permanently documented.
