ABSTRACT:
A tooth inclination apparatus for allowing assessment of the angle of inclination of an incisor tooth or cast thereof includes a plane element providing a flat datum surface for resting against e.g. the upper molars in the maxillary plane. From the underside of the plane element projects a protractor portion with a graduated angular scale which measures the angular deviation of an indicator pin pivoted to the plane member and moved to contact the tooth whose inclination is being measured. Other mechanical or electro-optic devices may be used to determine the inclination of the incisor relative to the datum surface.
