Abstract

Strips are prepared from a stack of two superposed metallized polymer films, each film having piezoelectric properties. The stack is coated with a conventional plastically deformable wax impression material to provide the normal visual indication of bite deflection and premature teeth engagement. The stack of metallized polymer films provides means through which sliding bite forces exerted during occlusal analysis may be monitored and recorded.
