Problems solved by technology

[0004] However, the existing indirect bonding technology cannot match the arch wire at the same time during bonding, and can only configure the arch wire after bonding
Therefore, the doctor's operation time is increased; and it is difficult to restore the position of the arch wire in the original design, resulting in a reduction in the efficiency of correction
[0005] Moreover, when operating in the mouth, the doctor is likely to install the anti-arch wire due to insufficient light in the oral cavity, or forget to handle the end of the arch wire, causing the patient to be stabbed by the arch wire

Embodiment 1

[0053] Such as Figure 1-Figure 5 As shown, the orthodontic bracket positioning unit of Embodiment 1 includes a bracket positioning block 10 and an occlusal positioning block 20 that are detachably connected to each other.

[0054] Specifically, the occlusal positioning block 20 is a 3D customized block with six surfaces, including the occlusal surface, the gingival surface, the labial surface, the lingual surface, the mesial surface and the distal surface, the occlusal surface and the gingival surface are opposite, the labial surface and the The sides of the tongue face each other, and the mesial and distal faces face each other.

[0055] The gingival surface 25 of the occlusal positioning block 20 corresponds to the occlusal surface of the tooth 50 using the orthodontic bracket 30 , and the gingival surface of the occlusal positioning block 20 is coupled with the occlusal surface of the tooth 50 .

[0056] The lip side of the occlusal positioning block 20 is provided with a...

Embodiment 2

[0084] Such as Figure 1-Figure 5 As shown, the positioner of the orthodontic bracket 30 of Embodiment 2 includes a plurality of positioning units of Embodiment 1, and the positioning units act on the teeth 50 on the same side, that is, act on the maxillary teeth 50, or act on the mandibular teeth 50.

[0085] Each positioning unit includes a bracket positioning block 10 and an occlusal positioning block 20 that are detachably connected to each other. The bracket positioning blocks 10 of two adjacent positioning units are connected with soft edges in the near-distal direction, and the occlusal positioning of each positioning unit Block 20 is an independent entity.

[0086] The positioning method of the locator of embodiment 2, its steps include:

[0087] 1) A plurality of bracket positioning blocks 10 are produced through standardized production, and the orthodontic brackets 30 are matched and coupled to the bracket positioning blocks 10. soft edge connection;

[0088] 2) ...

Embodiment 3

[0092] The positioner for the orthodontic bracket 30 in Embodiment 3 includes a plurality of positioning units in Embodiment 1, and the positioning units act on the teeth 50 on the same side, that is, act on the upper teeth 50 together, or act on the mandibular teeth 50 together.

[0093] Each positioning unit includes a bracket positioning block 10 and an occlusal positioning block 20 that are detachably connected to each other. The occlusal positioning blocks 20 of two adjacent positioning units are connected with soft edges in the near-distal direction, and the occlusal positioning block of each positioning unit 20 are independent individuals.

[0094] The positioning method of the locator of embodiment 3, its steps include:

[0095] 1) A plurality of bracket positioning blocks 10 are produced through standardized production, and the orthodontic brackets 30 are matched and coupled to the bracket positioning blocks 10;

[0096] 2) After the digital model is obtained by taki...

Abstract

The invention discloses a positioning unit, a positioner and a positioning method of an orthodontic bracket. The positioning unit of an orthodontic bracket comprises bracket positioning blocks and occlusion positioning blocks, which are in detachable connection, wherein each occlusion positioning block is used for coupling with the occlusal surface of a tooth; each bracket positioning block is used for coupling with an orthodontic bracket and releasing the orthodontic bracket onto teeth; and an arch wire channel is formed in each bracket positioning block in the mesiodistal direction, and is used for leading an arch wire which is arranged in an arch wire slot of the orthodontic bracket to pass through. According to the positioning unit and the positioner, the arch wire channel is providedto prevent the arch wire slot from being occupied and can be coupled with the orthodontic bracket carrying an arch wire, and the arch wire is taken along during indirect bonding, so that the operationtime and operation steps can be reduced, pain of a patient can be relieved, the workload of a doctor can be reduced, and the development of the orthodontic technology can be greatly promoted.

Description

technical field [0001] The invention relates to the field of dental orthodontic treatment, in particular to a positioning unit, a positioner and a positioning method for an orthodontic bracket. Background technique [0002] In current orthodontic treatment, direct bonding is usually used when bonding brackets to tooth surfaces. Since the existing direct bonding technology is manually bonded according to the doctor's experience, this method is highly dependent on the doctor's bonding skills and visual observation. Its work intensity is high, the efficiency is not high, the repeatability is not good, and the accuracy is not ideal. Nevertheless, due to its intuitive nature, it is still widely used in clinical practice by most orthodontists. [0003] In order to overcome these disadvantages of direct bonding technology, indirect bonding technology was developed. The indirect bonding technology is to bond the orthodontic brackets on the working model first, and then transfer t...
