Abstract
Apparatus for evaluating bite characteristics of teeth, comprises an impression member with at least one layer of an elasto-plastic memory material that retains a bite impression, the memory material being optically isotropic or uniformly anisotropic and exhibiting as the result of bite conditions mechanical stress birefringence observable by polaroid light. The memory material may be a polymer, e.g. nylon or polyethylene. A polariscopic instrument arranged to examine the impression member has an illuminating white or monochromatic light source, a first linear or circular polarising filter arranged between the light source and a clamp for the impression member to be examined, and a second linear or circular polarising filter arranged to pass light transmitted through or reflected by the member to a magnifying eyepiece, the clamp being constructed to hold the member such that a bite impression in the member is not disturbed.
