An orthodontic appliance for moving the mandibular jaw relative to the maxillary jaw in response to jaws being closed is described. The orthodontic appliance includes a first member and a second member which is disconnected from the first member when jaws are in open position. The first member is adapted to be fixedly attached to one of mandibular or maxillary dental arches, and the second member is adapted to be rotatingly coupled with the other one of mandibular or maxillary dental arches. The first member and second member are in vertical alignment. During the closure of dental arches, the second member contacts the first member, and the rotation of the second member is initiated. Rotation of the second member pushes the mandibular jaw in either anterior or posterior direction.

Various embodiments of orthodontic appliances are disclosed to dispose a patient's lower dentition (2) and upper dentition (2) in Class I occlusion. A representative appliance (180) includes an occlusal ridge (182) that extends over the mesio-lingual cusp and the mesio-buccal cusp of a lower first molar (14a) on one side of the patient's dentition (2), and includes another occlusal ridge (182) that extends over the mesio-lingual cusp and the mesio-buccal cusp of a lower first molar (14b) on the other side of the patient's dentition (2). Such an appliance (180) addresses a Class II malocclusion by encouraging or facilitating movement of the mandible in a mesial or anterior direction such that each such occlusal ridge (182) ends up being disposed between a corresponding upper first molar (32a, 32b) and a corresponding second bicuspid (30a, 30b).

Method for manufacturing a dental expander having a first attachment member intended to be fixed to a first fixation tooth of a patient and an active member rigidly connected to the first attachment member. The method includes: a) generating a three-dimensional digital model of a dental arch having the fixation tooth or arch model; b) using the arch model as a basis for generating: a three-dimensional digital model of the first attachment member, wherein the model of the first attachment member that has an inner surface that substantially reproduces a part of the surface of the first fixation tooth, and/or a three-dimensional digital model of the active member; and c) using the model of the first attachment member as a basis for manufacturing the first attachment member and/or using the model of the active member as a basis for generating the active member.

A particularly simple orthodontic bracket manufactured using cutting and bending technology, proposed for a number of different indications, includes a base plate having an adhesive side and a visible side, and an element for the guided retention of a treatment arch wire. The bracket is made in one piece and has, as a guiding element, a longitudinal guiding bulge extending mesio-distally and shaped out of the plane of the base plate. A treatment arch wire can be guided through beneath the guide bulge, such that it lies against the base plate.

The present invention includes a geared orthodontic buccal tube assembly which comprises of a buccal tube with an elongated hook that engages one or more gearwheels which in turn engage a toothed surfaces to redirect the direction of the applied force pulling the buccal tube to prevent or reduce the movement of the anchor tooth thus reinforcing the anchor teeth.

A method and associated system. Such is for orthodontic treatment or for assessing shape of an aligner. Within an example, there is participation in communication of an assessment of the suitability of an aligner as a function of the value of: a tooth attribute of an analysis tooth zone of an analysis image, the tooth attribute relating to a separation between the tooth represented by the analysis tooth zone and the aligner represented on the analysis image, or an image attribute of an analysis image, the image attribute relating to a separation between at least one tooth represented on the analysis image and the aligner represented on the analysis image. The analysis image is an image of an aligner in a service position in which it is worn by the patient acquired by a cellphone more than 1 week, and is a photograph, or an image extracted from a film.
