Description

Technical field:

[0001] The utility model belongs to the field of dental correction appliances, and particularly relates to a lingual bracket with a notch, in particular to a solution in which an auxiliary tube has the notch. Background technology:

[0002] CN201420149107.8, a lingual bracket with an auxiliary tube, the lower surface of the bracket body is provided with anti-slip grooves, one end of the upper surface of the bracket body is provided with an auxiliary tube hole, and the other end is provided with a ligation groove, and the fixed wings on both sides of the ligation groove are extended outward to form a ligation groove. The lingual bracket has fixed wings and auxiliary tube holes, and can provide elastic archwires for passing and ligation at the same time, and can efficiently align teeth. In clinical bracket bonding operations, errors are inevitable. For example, when there are deviations in inclination, vertical height, and torsion, it will cause difficulties in alignment; and it is also difficult to re-bond the lingual bracket.

[0003] How to provide a more reasonable technical solution becomes the research object of the present invention. Summary of the invention:

[0004] The utility model aims to design a lingual bracket with a groove and an auxiliary tube with greater tolerance.

[0005] The technical solution of the utility model is implemented as follows: a lingual bracket with a notch, an auxiliary tube is provided at one end of the bracket body, and a ligation wing is provided at the other end; the characteristic is that a penetrating notch is processed in the middle of the auxiliary tube, and the auxiliary tube is divided into two sections by the notch, namely a left section tube and a right section tube, and the elastic arch wire can choose to pass through the left section tube and the right section tube at the same time, or pass through the left section tube or the right section tube and through the notch.

[0006] The auxiliary pipe is a double-hole pipe.

[0007] The auxiliary tube is a single-hole tube, and a horn is extended from the top of the tube toward at least one side.

[0008] The notch occupies more than half of the auxiliary pipe length.

[0009] The utility model divides the auxiliary tube into two parts, forms a notch for passing through in the middle, and cooperates with the double-hole tube or the horn on the top of the tube. The elastic arch wire has a large passing tolerance and is more flexible in operation, which greatly reduces the clinical difficulty. It has the characteristics of unique conception, simple structure and easy operation. Description of the drawings:

[0016] in

[0017] 1—Bracket body; 2—Ligation wing;

[0018] 3—auxiliary pipe; 31—notch; 32—left section pipe; 33—right section pipe; 34—partition rib; 35—corner;

[0019] 4—teeth; 5—elastic archwire; Specific implementation method:

[0020] Reference Figures 1 to 4 , a lingual bracket with a slot, a ligation wing 2 is provided at one end of the upper surface of the bracket body 1, and an auxiliary tube 3 is provided at the other end; various types of ligation hooks can be processed on the ligation wing 2, and a penetrating slot 31 is processed in the middle of the auxiliary tube 3, the slot 31 occupies more than half of the length of the auxiliary tube 3, and the auxiliary tube is divided into two sections by the slot 31, namely the left section tube 32 and the right section tube 33; clinically, when adjacent brackets are tilted or twisted, the elastic arch wire can choose to pass through the left section tube 32 or the right section tube 33 and through the slot 31.

[0021] The actual auxiliary pipe 3 has the following two types of structures:

[0022] 1. The auxiliary pipe 3 is a double-hole pipe, such as Figure 3 The double-hole tube can be a structure with a partition rib 34 in the middle, or a through hole with a convex point in the center. A single bracket is provided with the option of passing through the double-hole by borrowing, and more combinations of passing with adjacent brackets. That is, the elastic arch wire can choose to pass through the upper hole or the lower hole of the double-hole tube of the adjacent bracket at the same time, or the upper hole and the lower hole can be passed by borrowing, or a combination of the upper hole and the lower hole in a bracket can be selected, and a solution of passing only through the left section tube or the right section tube and passing through the notch can be selected.

[0023] Second, the auxiliary pipe 3 is a single-hole pipe, such as Figure 1 , the top of the tube has a horn 35 extending toward at least one side. Compared with the double-hole tube, the single-hole tube cannot borrow position by itself and can only seek external support. Therefore, a corresponding horn design is provided on one or both sides of the top of the tube, so that the elastic arch wire can be selected to pass through the left section tube 32 or the right section tube 33, and through the notch 31, the elastic arch wire is constrained outside the auxiliary tube 3. Figure 2It is a schematic diagram showing that the two sides of the top of the tube are correspondingly designed with horns 35.

[0024] Reference Figure 4 The bracket body 1 is bonded to the lingual side of the tooth 4, and the elastic arch wire 5 can pass through the upper hole or lower hole of the adjacent bracket body, or the bracket body tilted according to the bonding error can be inserted obliquely into the upper and lower holes to meet clinical correction needs.

[0025] Reference Figure 5 The elastic arch wire 5 can pass through the left section tube 32 or the right section tube 33 on one side, and then pass through the notch 31, and be clamped at the corner of one side of the auxiliary tube, with the help of the corner to form a force fulcrum, or be tied or guided to the adjacent bracket.
