Abstract
Abstract A horizontal bite plate support combined with a dental articulator which has a calibrated vertical post member and which has a connection to support a face bow in a position to establish the location of a patient''s transverse mandible hinge axis. The bite plate support has a calibrated elongated handle portion with a slide member on the handle portion slidably receiving and being clampingly engageable with the handle portion and also slidably receiving the vertical post member and being clampingly engageable therewith. The horizontal bite plate support has an inner plate member recessed to interlock with a smooth bite plate, whereby the bite plate can be positively supported in a horizontal position corresponding to the location of a patient''s occlusal area relative to his transverse mandible hinge axis.
