Lingual bracket having notch

Abstract

A lingual bracket having a notch (31). One end of a bracket body (1) is provided with an auxiliary tube (3), and the other end is provided with a ligation wing (2). A penetrating notch (31) is machined in the middle of the auxiliary tube (3). The auxiliary tube (3) is divided into two sections by means of the notch (31), which are a left section tube (32) and a right section tube (33). An elastic arch wire (5) can selectively pass through the left section tube (32) and the right section tube (33) at the same time, or pass through the left section tube (32) or the right section tube (33) and pass through the notch (31). By dividing the auxiliary tube (3) into two parts with a notch (31) for passage formed in the middle and arranging a double-hole tube or a horn (35) on top of the tube, the elastic arch wire (5) has a large penetration tolerance and allows more flexible operation, greatly reducing clinical difficulty. The lingual bracket has the characteristics of a unique concept, a simple structure, and ease of operation.

Description

Bracket with notched lingual side TECHNICAL FIELD

[0001] The present application belongs to the field of dental appliances, and particularly relates to a lingual bracket, especially a scheme of a bracket with a notched auxiliary tube. BACKGROUND

[0002] CN201420149107.8, a lingual bracket with an auxiliary tube, the lower surface of the bracket body is provided with anti-skid lines, the upper surface of the bracket body is provided with an auxiliary tube hole at one end and a ligation groove at the other end, the two fixed wings forming the ligation groove are extended outward, and the ligation groove is formed. The lingual bracket has fixed wings and an auxiliary tube hole, and can provide the need for elastic arch wire passing and ligation, and can efficiently align teeth. In clinical practice, errors will inevitably occur during bracket bonding operation, such as inclination, vertical height, and torsion deviation, which will bring difficulties to alignment; and it is also difficult to re-bond the lingual bracket.

[0003] How to provide a more reasonable technical scheme, that is, the object of the present application. SUMMARY

[0004] The purpose of the present application is to design a lingual bracket with a notched auxiliary tube with greater tolerance.

[0005] The technical scheme of the present application is implemented as follows: a lingual bracket with a notched auxiliary tube, one end of the bracket body is provided with an auxiliary tube, and the other end is provided with a ligation wing; characterized in that: a through notch is formed in the middle of the auxiliary tube, which divides the auxiliary tube into two segments, namely a left segment tube and a right segment tube, and the elastic arch wire can pass through the left segment tube and the right segment tube at the same time, or pass through from the left segment tube or the right segment tube and through the notch.

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

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

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

[0009] The present application divides the auxiliary tube into two, forms a through notch in the middle, and cooperates with a double-hole tube or a horn at the top of the tube, so that the elastic arch wire has greater tolerance and is more flexible to operate, greatly reducing the clinical difficulty; and has the characteristics of unique concept, simple structure, and easy operation.

[0017] Referring to Figs. 1 to 4, the notched lingual bracket, the bracket body 1 has a ligature wing 2 at one end of the upper surface and an auxiliary tube 3 at the other end; various types of ligature hooks can be provided on the ligature wing 2, and the auxiliary tube 3 has a penetrating notch 31 in the middle part, the notch 31 occupies more than half of the length of the auxiliary tube 3, and the auxiliary tube is divided into two segments, i.e., a left tube 32 and a right tube 33, by the notch 31; when adjacent brackets are inclined or twisted in clinical practice, the elastic arch wire can be selected to pass through the left tube 32 or the right tube 33 and through the notch 31.

[0018] The actual auxiliary tube 3 has the following two types of structures:

[0019] I. The auxiliary tube 3 is a double-hole tube, as shown in Fig. 3, which can be a structure with a partition rib 34 in the middle or a through hole with a protruding point in the center. It provides the option of selecting a double-hole tube for a single bracket to pass through, as well as more combinations of passing through adjacent brackets. That is, the elastic arch wire can be selected to pass through the upper hole or the lower hole of the double-hole tube of the adjacent bracket at the same time, or pass through the upper hole and the lower hole, or select a combination of passing through the upper hole and the lower hole of a bracket, as well as the option of passing through only the left tube or the right tube and passing through the notch.

[0020] II. The auxiliary tube 3 is a single-hole tube, as shown in Fig. 1, which has a horn 35 extending at least to one side of the top of the tube. Compared with the double-hole tube, the single-hole tube cannot pass through by itself and can only seek external support, so the horn is designed on one side or both sides of the top of the tube, which provides the option of passing through the left tube 32 or the right tube 33 of the elastic arch wire and passing through the notch 31, and provides the constraint of the elastic arch wire outside the auxiliary tube 3. Fig. 2 is a schematic diagram of the top of the tube with horns 35 designed on both sides.

[0021] Referring to Fig. 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 the lower hole of the adjacent bracket body, or select an oblique insertion of the upper hole or the lower hole according to the inclined bracket body due to bonding errors, to meet the clinical treatment needs.

[0022] Referring to Fig. 5, the elastic arch wire 5 can be passed through the left or right section tube 32 or 33 on one side, and then passed through the slot 31, and clamped at the horn on one side of the auxiliary tube, with the horn as a force fulcrum, or ligated or guided to the adjacent bracket.

Claims

1. A notched lingual bracket, the bracket body has an auxiliary tube at one end and a ligating wing at the other end; characterized in that: The auxiliary tube is processed with a penetrating notch in the middle, which divides the auxiliary tube into two sections, left section tube and right section tube, and the elastic arch wire can be selected to pass through the left section tube and the right section tube simultaneously, or pass through the left section tube or the right section tube and through the notch.

2. The notched lingual slot bracket of claim 1 wherein: The auxiliary tube is a double-hole tube.

3. The notched lingual archwire slot bracket of claim 1 wherein: The auxiliary tube is a single-hole tube, and at least one horn extends from the top of the tube towards one side.

4. A notched lingual bracket according to claim 1, 2 or 3, wherein: The notch occupies more than half of the length of the auxiliary tube.
