[0004] Patent CN112773525A discloses an invisible vertical maxillary orthodontic device and its use method, including a transparent appliance, and a pair of external force pulling parts matched with the transparent appliance, the external force pulling parts and the The transparent aligner is detachably connected, and the external force puller exerts a vertical upward force on the transparent aligner. In this patent, a connection accessory is provided on the transparent aligner, and the transparent aligner is adjusted by using the easily detachable external force puller. The device exerts an upward vertical pulling force, so that the transparent appliance produces a vertical correction force on the maxillary dentition, and controls the vertical direction of the maxillary teeth. However, it cannot control the torque, and the effect of the teeth moving forward and correcting the torsion is poor

Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Such as figure 1 , an invisible orthodontic system combining a lingual groove-type attachment with a segmented arch, including a transparent appliance 1, a lingual arch wire 2, and a lingual attachment 3 attached to the inside of a tooth 4, and the lingual arch wire 2 is installed on the transparent appliance 1, and is integrated with the transparent appliance 1. When the transparent appliance 1 is worn on the tooth 4, the lingual arch wire 2 is engaged with the lingual attachment 3, and the lingual arch wire 2 is applied to the lingual attachment 3. force. After the lingual arch wire 2 enters the groove of the lingual attachment 3, the active or passive force generated with the groove wall is transmitted to the teeth through the lingual attachment 3 to control the movement of the teeth.
[0032] Specifically, the transparent aligner...

The invention relates to an invisible orthodontic system combining a lingual groove type accessory with a segment arch. The invisible orthodontic system comprises a transparent orthodontic appliance, a lingual arch wire and a lingual accessory; the lingual accessory is attached to the inner side of teeth; the lingual arch wire is arranged on the inner side of the transparent orthodontic appliance and is combined with the transparent orthodontic appliance into a whole; when the transparent orthodontic appliance is worn on teeth, the lingual arch wire is clamped with the lingual accessory; and the lingual arch wire applies acting force to the transparent orthodontic appliance. Compared with the prior art, the lingual arch wire is arranged in the transparent orthodontic appliance, so that the transparent orthodontic appliance can control the torque to generate certain acting force, and the orthodontic effect is improved.
Description
technical field [0001] The invention relates to the technical field of orthodontic auxiliary devices, in particular to an invisible orthodontic system with a lingual groove-type attachment combined with a segmented arch. Background technique [0002] Transparent aligners are a kind of invisible aligners for the treatment of misaligned teeth, which can meet the aesthetic needs of patients during orthodontics. This orthodontic technology is to scan the patient's dentition model by computer, simulate the tooth movement on the scanned computer model, and then print the tooth movement process into a series of transparent braces. With the wearing of the transparent braces, the teeth will move accordingly with the changes in the braces . [0003] Although transparent aligners can meet the aesthetic needs of patients, their orthodontic effect is far inferior to that of metal braces. Only the force of transparent aligners is used to push the molars to move. The tooth movement speed ...
