Patent number: 5464349Abstract: An orthodontic bracket, preferably in the form of a buccal tube, is provided for connecting an orthodontic archwire to each mandibular first molar of a patient. The bracket has an archwire groove oriented to maintain the archwire at a positive rotation angle relative to the point on the surface of the molar at which the bracket is connected. The rotation angle is preferably approximately 2.degree. for Caucasian patients and approximately 4.degree. for Asian patients. The groove, while inclined to a positive (distal) rotation angle of greater than zero, may additionally be inclined mesially relative to the wire to account for smaller cross-sectional dimensions of the wire relative to the groove. In making a custom orthodontic appliance, a computer designs such buccal tubes with the grooves rotated to an angle optimally calculated for the patient.Type: GrantFiled: August 4, 1994Date of Patent: November 7, 1995Assignee: Ormco CorporationInventors: Craig A.

Patent number: 5459886Abstract: A swimming pool has a recirculating pump and filter. A drain line from the high pressure side of the pump drains excess water through a hydraulically operated drain valve remote from the pool. A long narrow tube from the high pressure line drains into the pool at a float valve. When the level of water in the pool is too high, the float valve opens, and pressure in the tube drops. Pressure in the tube operates the drain valve, opening the drain valve when the level is high and the pressure is low, and closing the drain valve when the level is not high, the float valve is closed and the pressure is high. The invention may be alternatively practiced with a drain valve that is opened by a high control pressure using a float valve that closes when the pool level is high. A timer controlled valve in the tube prevents opening the drain valve during preselected times when the pool is occupied.Type: GrantFiled: August 16, 1994Date of Patent: October 24, 1995Inventors: Mark Payne, Amy Payne

Patent number: 5456600Abstract: Coordinated orthodontic archwires are provided based on a method of designing custom orthodontic appliances based in individual patient anatomy and, based on a plurality of such custom designs, designing and manufacturing a standardized appliance for patients of average dental anatomy. From such method, a relationship is established for coordinating one archwire to another of any given design. The coordinated archwires so provided include an upper archwire that is an expansion of a lower archwire, and in addition, when the shapes of the archwires are superimposed, are spaced apart more in the vicinity of the cuspids and first bicuspids than in the vicinity of the incisors and, preferably, also the second bicuspids. The spacing difference is at least 0.005 inches, particularly for an appliance with low profile brackets, and is up to 0.025 or 0.035 inches for an appliance with the more conventional brackets. The spacings are determined as a function of the length of the wire from the midline of the wire.Type: GrantFiled: August 4, 1994Date of Patent: October 10, 1995Assignee: Ormco CorporationInventors: Craig A.
