ABSTRACT:
Dental impression strips prepared from metallized polymer film having piezoelectric properties are coated with a conventional plastically deformable wax impression material to provide the normal visual indication of bite deflection and premature teeth engagement. The metallized polymer film provides means through which force exerted during occlusal analysis may be monitored and recorded. By coating the metallized polymer film with a non-permanently deformable and reusable plastic, the monitoring and recording may readily be demonstrated to the dentist and patient.
