Abstract
The present invention provides for an apparatus and method for registration of the dental bite of a patient. An impression plate is provided for insertion into the patient's mouth and incorporates an upper incisor engagement means and an extension protruding out of the patient's mouth. An independent lower incisor engagement means is provided with an extension which is complementary to the upper incisor extension, wherein a groove in the lower extension mates with the upper extension which slides freely therein. Protrusion and retrusion of the lower jaw with respect to the upper jaw causes an anterposterior sliding movement of the lower extension with respect to the upper extension. Calibrations are provided on the extensions for measuring the relative movement therebetween. A lock is provided between the extensions to hold the extensions at a given calibration for registering the bite at that calibration.
