Patent ID: 6945779

Claim:
A tooth inclination assessment apparatus for allowing assessment of the angle of inclination of an incisor tooth or cast thereof in or from the human or animal body, which apparatus comprise: a datum element defining a generally flat datum surface ( 14 ) for being placed in use against two or more upper or lower molars or pre-molars thereby to become generally aligned with the respective mandibular or maxillary plane, and an angular detector ( 18 - 24 ) associated with said datum element for detecting the angular disposition relative to said datum surface ( 14 ) of at least one of the upper or lower incisors respectively, characterised in that said angular detector ( 18 - 24 ) comprises an indicator member ( 22 ) pivotally mounted with respect to said datum surface ( 14 ) and extending to opposite sides of said datum surface, to define a tooth contact portion to one side, and a measuring portion to the other, and an angle measurement device ( 18 ) associated with said datum surface ( 14 ) to allow the angle of deflection of the indicator member ( 22 ) relative to the datum surface ( 14 ) to be determined.
