The occlusal position of a patient is measured by means of light transmission through a layer of a polysiloxane which is not cross-linked. This material forms an exceptionally accurate impression of a patient's bite essentially instantaneously and enables subsequent recording and analysis of the bite in a matter of minutes.

Method and apparatus for occlusal position measurement and recording

Method for occlusal position measurement and recording

A spinning end of a rotating instrument is used to deform an adhesive material without the adhesive material adhering to the instrument. This process is particularly suited for packing dental composites within oral cavities.

Method for shaping an adhesive material

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.

Method of permanently recording occlusal contacts

An occlusal clearance indicator for measuring the distance between a tooth prepared to receive a cast restoration and an opposing tooth.
