<p>The present invention provides for an apparatus and method for registration of the dental bite of a patient. An impression plate (12) is provided for insertion into the patient's mouth and incorporates an upper incisor engagement means (10) and an extension (7) protruding out of the patient's mouth. An independent lower incisor engagement means (21) is provided with an extension (16) which is complementary to the upper incisor extension (7), wherein a groove in the lower extension (16) mates with the upper extension (7) which slides freely therein. Protrusion and retrusion of the lower jaw with respect to the upper jaw causes an anteroposterior sliding movement of the lower extension (16) with respect to the upper extension (7). Calibrations (18) are provided on the extensions (7 and 16) for measuring the relative movement therebetween. A lock (23) is provided between the extensions (7 and 16) to hold the extensions at a given calibration for registering the bite at the calibration.</p> |
