Description

Technical Field

[0001] The utility model belongs to the technical field of oral orthodontics, and in particular relates to an orthodontic fixator. Background Art

[0002] Orthodontics generally refers to tooth correction, and also refers to the treatment process of using oral technology to correct uneven teeth, abnormal tooth shape, and abnormal tooth color. Orthodontic retainers are a type of device that fixes and corrects teeth during the orthodontic process, and are mainly used to correct uneven teeth.

[0003] Currently common orthodontic retainers are mainly composed of archwires, brackets, bands and accessories. When using this type of orthodontic retainer, the brackets are bonded to the tooth surface, the brackets on different teeth are connected through the archwires, and the misaligned teeth are trimmed by adjusting the archwire spacing according to the actual oral conditions of the patient.

[0004] During use, orthodontic retainers in the prior art mainly use the method of overall adjustment of the archwire to pull and trim the misaligned teeth. The archwire cannot be independently adjusted according to the actual oral conditions of the patient. At the same time, the overall adjustment of the archwire increases the complexity of the force applied to teeth in different positions in the oral cavity, which makes it difficult to control the correction effect of the orthodontic retainer, resulting in poor use effect of the orthodontic retainer.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0036] like Figures 4 to 5 As shown, the buckle round cover 3042 is arranged in cooperation with the driving bolt end 3021. It is convenient to assemble and limit the outer surface of the arch wire limit block 301 and the assembly hole that matches the driving bolt end 3021 through the buckle round cover 3042. A pair of clamping limit blocks 3043 are clamped and connected with the arch wire limit block 301. The clamping limit blocks 3043 are buckled to protect the arch wire limit block 301.

[0037] During specific use, multiple sets of arch wire limit blocks 301 are bonded to the tooth surface in the patient's mouth, and the arch wire 2 is assembled in the multiple sets of arch wire limit blocks 301 by snap-fitting, and a pair of arch wire fixing brackets 1 are bonded to the tooth surface in the patient's mouth, and the arch wire 2 is sleeved and fixed by the pair of arch wire fixing brackets 1.

[0038] Subsequently, according to the actual situation of the teeth in the patient's mouth, the locking bolt rod 3022 can be rotationally driven by applying a force to the driving bolt end 3021, and the arch wire 2 in the arch wire limit block 301 can be rotated and tightened by rotating the locking bolt rod 3022. The arch wire 2 can be tightened by controlling the rotation of the arch wire adjustment bolt 302, thereby adjusting the external force on the teeth in the patient's mouth.

[0039] After the adjustment is completed, the protective sleeve 303 and the buckled protective cover 304 can be sleeved on the outside of the arch wire limiting block 301, so that the protective sleeve 303 can flexibly protect the patient's oral cavity, and the buckled protective cover 304 can buckle and protect the arch wire limiting block 301, thereby improving the use effect of the arch wire limiting assembly 3.
