Patent number: 11160638Abstract: The disclosure relates to an orthodontic system and treatment method, including an arrangement of orthodontic brackets against the patient's teeth such that the depth of the respective archwire slots of the brackets generally increases from the anterior teeth moving toward the posterior teeth. The gradual increase of the archwire slot in the bracket arrangement provides for finer control over the movement of the anterior teeth, while providing sufficient control and freedom of movement for the posterior teeth.Type: GrantFiled: April 20, 2018Date of Patent: November 2, 2021Assignee: WORLD CLASS TECHNOLOGY CORPORATIONInventors: Thomas Pitts, Alberto Ruiz-Vela

Patent number: 10631957Abstract: A self-ligating orthodontic bracket has a sliding archwire cover that has a top surface congruent with the top surface of an upper body portion having an archwire slot. The cover has a resilient locking tab that slides across the slot, bending upward as it encounters a ridge on the other side of the slot, and latching to the ridge to secure the cover in a closed position. The cover has a modified dovetail shape with flared bottom portions that slideably engage guides for reciprocal opening and closing sliding motion. A groove in the slide support track engages the locking tab in the open position preventing it from disengaging from the upper body portion.Type: GrantFiled: June 17, 2015Date of Patent: April 28, 2020Assignee: WORLD CLASS TECHNOLOGY CORPORATIONInventors: Rolf Hagelganz, Juergen Bathen

Patent number: 9566134Abstract: A set of orthodontic brackets is provided in combination with an archwire extending over an arc when fitted to the set of orthodontic brackets. The archwire has at least one radius of curvature over the length of its arc, and each one of said brackets in the set has an archwire slot. Each slot has at least one surface supporting the archwire which is contoured to have a radius of curvature that matches the radius of curvature along the arc of the archwire at that point. A round archwire is preferred and the archwire slots may be formed as tubular channels to provide better torque action for the archwire.Type: GrantFiled: April 10, 2013Date of Patent: February 14, 2017Assignee: World Class Technology CorporationInventors: Rolf Hagelganz, Juergen Bathen

Patent number: 8807995Abstract: The invention relates to a tooth top part for a tooth correction means (1), with a base body (2) at which a tooth support surface (5, 25, 45) is formed for being fixed at a tooth surface (3) by bonding, and which is provided with a guide recess (12, 32, 52) which is formed for receiving a connecting means (4, 24, 44) for coupling neighboring tooth top parts (2, 22, 42) and which passes through the base body (2) in spaced relationship to the tooth support surface (5) along a guiding axis (17). According to the invention, the base body (2) comprises a substantially triangular or circular section shaped cross section (11, 11a, 31, 51) in a cross sectional plane (10) normal to the guiding axis (17).Type: GrantFiled: August 7, 2012Date of Patent: August 19, 2014Assignee: World Class Technology CorporationInventors: Robert Kabbani, Juergen Bathen, Rolf Hagelganz
