Abstract: An orthodontic appliance has a ramp extending laterally from the posterior teeth on one of the patient's mandibular/maxillary dental arches. The ramp is curved with a J-shaped occlusal ramp surface extending diagonally upward toward its anterior aspect. The ramp also includes a stop at the gingival end of the ramp surface. A post extends laterally from the posterior teeth on the other dental arch. The post contacts and slides along the ramp surface toward the stop to guide the mandible forward as the mandible closes. The post seats against the stop to define a limit for closure of the mandible.

Abstract: A lingual orthodontic appliance contains a lingual bracket for an anterior tooth and an archwire. The orthodontic appliance is defined in a three-dimensional Cartesian coordinate system. The archwire extends in a first and a second dimension of the coordinate system generally U-shaped. In the third dimension the archwire is generally flat. The archwire has a rectangular cross-section with a height defined by the longer side of the rectangular cross-section. The height is oriented along the third dimension. The bracket further has a bracket pad and a bracket body. The bracket body forms a slot for receiving the archwire. The slot is formed by at least two opposing parallel slot side faces and a slot ground face arranged perpendicular thereto. The slot has a width defined by the distance between the slot side faces. The width matches with the height of the archwire. The invention is advantageous for an orthodontic treatment of teeth requiring good tip and rotation control.

Abstract: A method for producing a one-piece orthodontic jig and brackets employs a computer-aided design (CAD) system to create a model of a patient's dental anatomy. A set of orthodontic brackets and their desired positions are also designed in the CAD model. An orthodontic jig for temporarily positioning the brackets during the bonding process is then designed that includes features for registering the jig to selected teeth, together with connecting members that detachably connect the brackets to the jig and hold the brackets in their desired position on the patient's teeth during the bonding process. The orthodontic jig and brackets is fabricated as a single piece by computer-controlled manufacturing (e.g., 3D printing) based on the CAD model.

Abstract: A lingual orthodontic appliance contains a lingual bracket (12) for an anterior tooth and an archwire (20). The orthodontic appliance is defined in a three-dimensional Cartesian coordinate system. The archwire (20) extends in a first and a second dimension of the coordinate system generally U-shaped. In the third dimension the archwire (20) is generally flat. The archwire (20) has a rectangular cross-section with a height defined by the longer side of the rectangular cross-section. The height is oriented along the third dimension. The bracket further has a bracket pad (2) and a bracket body (1). The bracket body (1) forms a slot (4) for receiving the archwire (20). The slot (4) is formed by at least two opposing parallel slot side faces and a slot ground face arranged perpendicular thereto. The slot (4) has a width defined by the distance between the slot side faces. The width matches with the height of the archwire (20).

Abstract: A method for producing a one-piece orthodontic jig and attachments employs a computer-aided design (CAD) system to create a model of a patient's dental anatomy. A set of orthodontic attachments and their desired positions are also designed in the CAD model. An orthodontic jig for temporarily positioning the attachments during the bonding process is then designed that includes features for registering the jig to selected teeth, together with connecting members that detachably connect the attachments to the jig and hold the attachments in their desired position on the patient's teeth during the bonding process. The orthodontic jig and attachments is fabricated as a single piece by computer-controlled manufacturing (e.g., 3D printing) based on the CAD model.
