Device for Measuring the Angles of Inclination of the Incisor Occlusal Plane of Equidae and Otehr Animals

A device suitable for measuring an angle of inclination between actual and reference incisor occlusal planes in an animal comprising:

• a contact element having a first rotation axis coinciding with an intersection line between a sagittal plane and an actual incisor occlusal plane;
• a first movable member rotatably coupled to said contact element around said first rotation axis;
• a graduated scale provided on said contact element or on said first movable member for measuring a relative rotation thereof, wherein said contact element comprises a locator plate sized to fit inside an animal's mouth between the upper and lower dental arches, and to be aligned with said incisor occlusal plane;
• an abutment plane coupled to said locator plate and aligned with a limit anterior plane perpendicular to said sagittal plane and said actual incisor occlusal plane, such to define an anterior sagittal point by an intersection of said limit anterior plane with said sagittal plane and with said actual occlusal plane;
• and
• a second movable member rotatable about a second rotation axis which is perpendicular to and which meets said first rotation axis in said anterior sagittal point, said second movable member being rotatably coupled to said contact element.
