Description

Maxillary traction corrector Technical Field The utility model relates to the field of dental correction devices, in particular to a maxillary traction corrector. Background The upper jaw traction corrector is an orthodontic device for treating bone III type misjaw deformity, and is mainly aimed at patients with upper jaw hypogenesis or lower jaw hyper-development. Such appliances stimulate the growth and movement of the maxilla by applying external force, thereby improving the occlusal relationship and facial profile of the patient, and the conventional extraoral anterior traction appliance is composed of an intraoral portion and an extraoral portion. The intraoral portion is typically a fixed or adhesive maxillary expander with outwardly extending hooks and the extraoral portion is a mask with cushions to support the chin and forehead. The hooks of the expander are connected with the support rod of the mask through the rubber band to generate forward and downward force, so as to draw the maxilla to move forward. Existing dual and single rod maxillary traction orthoses typically employ a metal frame structure that is designed to provide stable traction but has significant limitations. The hard contact points of the metal frame may cause a feeling of compression to the head and face of the wearer, especially at rest or sleep, which may significantly increase discomfort and may even affect the normal sleeping posture of the wearer. In addition, the metal frame has a large weight, further reducing wearing comfort, and especially for children, the design is difficult to adapt to the long-term wearing requirement. Therefore, developing an appliance that can cancel a metal frame and improve wearing comfort and convenience is an important direction in the current technical field. For example, application number 201720717248.9 in the prior art is an utility model patent, a double bridge type dislocation maxillary cusp corrector is used for correcting the dislocation eruption in the middle of the maxillary cusp, the corrector comprises a double-sided maxillary premolars belt ring, a double-sided maxillary molar belt ring, a double-sided bridge body, a maxillary cusp bracket, stainless steel correction archwire and an elastic chain ring, the bridge body is quadrilateral, two ends of the bottom edge of the bridge body are respectively welded with the cheek surfaces of the maxillary premolars belt ring and the maxillary molar belt ring on the same side, the top edge and the bottom edge are both welded with cheek surface pipes, the maxillary cusp bracket is provided with grooves, two ends of the stainless steel correction archwire are respectively connected with cheek surface pipes on the top edge or the bottom edge of the double-sided bridge body, the stainless steel correction archwire can pass through the grooves, one end of the elastic chain ring is connected with the maxillary cusp brackets, the other end of the elastic chain ring is connected with the stainless steel correction archwire or the cheek surface pipes on the same side as the maxillary cusp bracket, the upper jaw is pulled far to the same side as the maxillary cusp brackets, and the upper cusp is far away from the side of the maxillary cusp brackets, and the upper cusp is far away from the maxillary cusp brackets and the upper jaw brackets are far away from the side of the patient, and the upper cusp is far aligned, and the patient is far from the wound, and the patient is caused.
