Abstract: A tool for measuring the inclination of maxillary incisors can accurately quantify the clinical inclination of the maxillary incisors relative to a true horizontal reference plane before and during dental treatment. The tool includes a stationary base and a measuring arm pivotably connected to the base. The base includes a main window defined therethrough and a spirit level. The movable arm includes a protractor, a sleeve connected to the protractor, and a sliding sheet slidably received within the sleeve. An adjustable incisor guide at a measuring end of the sliding sheet includes an incisor ledge for receiving an incisor edge during measurement. The spirit level can be used to align the base with the true horizontal plane and the movable arm can be raised until the incisor ledge contacts the incisor edge and the sliding sheet contacts the facial surface of the maxillary incisor.

Abstract: Pliers for making measurable torque bends in orthodontic archwires include upper and lower grips that are pivotally connected to each other. The upper grip is attached to a lower jaw having a first lower wing and a second lower wing. At least one slot is defined in an upper surface of each lower wing for receiving a portion of an archwire therein. The lower grip is attached to an upper jaw. The upper jaw includes a first upper wing and a second upper wing. A pivoting rod is pivotally connected to the first and second upper wings. A lever arm slidably engages a central portion of the pivoting rod. End portions of the pivoting rod extend through the upper wings and are connected to protractors. The lever arm includes at least one channel on a bottom surface for receiving a portion of the archwire between the lower wings.

Abstract: The occlusal canting identifying tool includes a frame having an elongated horizontal portion and a pair of parallel side arms movably attached to the horizontal portion at opposite ends thereof. The tool further includes a vertical arm centrally positioned on the front of the horizontal portion and a measuring assembly positioned on the rear of the horizontal portion. The measuring assembly includes a protractor rotatably attached to the rear of the horizontal portion, the protractor being configured to rotate on a horizontal axis in relation to the horizontal portion, and a bite plate connected to the protractor, the bite plate being adjustable forward and backward in relation to the protractor. The patient is instructed to bite on the bite plate, and if occlusal canting is present, the degree of canting is quantified by rotation of the protractor.
