Description

Technical field:

[0001] The utility model belongs to the field of dental orthodontic appliances, in particular to a lingual bracket. Background technology:

[0002] The brackets all include a base plate and a ligature wing. The base plate is used to bond to the tooth surface to transmit the correction force. At present, the shape of the base plate is similar to the shape of the lingual teeth, which is rectangular. When this shape is applied to the lingual side of the incisors and canines, there are the following defects: 1. The inclination of the bracket main axis is not clear; 2. When adjusting the bracket, the mesiodistal edge of the bracket is easy to interfere with the lingual edge ridge of the tooth, affecting the positioning.

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

[0004] The utility model aims to design a lingual bracket with a bottom plate in a T-shaped structure.

[0005] The technical solution of the utility model is implemented as follows: a lingual bracket includes a connected bottom plate and a ligation wing, characterized in that the bottom plate is a T-shaped structure, having a transverse section and a longitudinal section, an auxiliary tube is processed on the surface of the transverse section, and a ligation wing is processed at the end of the longitudinal section.

[0006] The two edges of the transverse section of the bottom plate are parallel, the two edges of the longitudinal section are parallel, and the angle between the center lines of the transverse section and the longitudinal section is between 90±15.

[0007] The ligation wing is processed with a ligation hook on one side facing the transverse section, and a ligation notch on the other side.

[0008] A slide groove is processed in the middle of the ligation wing, and a movable wing is arranged in the slide groove.

[0009] A fracture is cut on the auxiliary tube corresponding to the middle slide groove of the ligation wing, the fracture and the side wall of the slide groove are in the same plane, and the side wall is perpendicular to the central axis of the auxiliary tube.

[0010] The utility model has the characteristics of unique conception, simple structure and convenient bonding and positioning; the bracket bottom plate is in a T-shaped structure, which can provide horizontal and vertical references and a strong sense of positioning direction, while the narrowed longitudinal section can avoid interference from the edges on both sides of the teeth.

[0016] 1 - bottom plate; 11 - transverse section; 12 - longitudinal section;

[0019] 4—movable wings; Specific implementation method:

[0020] Reference Figure 1 , Figure 2 and Figure 3 The lingual bracket includes a connected base plate 1 and a ligature wing 2. The base plate 1 is a T-shaped structure, having a transverse section 11 and a longitudinal section 12. During cutting, the two edges of the transverse section 11 are parallel, and the two edges of the longitudinal section 11 are parallel, highlighting the role of the longitudinal and transverse references; and the center line angle between the transverse section 11 and the longitudinal section 12 is between 90±15, corresponding to the inclination angles of the incisors and canines on the left and right sides, so that the transverse section 11 is parallel to the incisal edge of the tooth, and the longitudinal section 12 is consistent with the inclination of the tooth axis, meeting the clinical selection.

[0021] An auxiliary tube 3 is processed on the surface of the transverse section 11, and a ligation wing 2 is processed at the end of the longitudinal section 12, which respectively provide the needs of auxiliary steel wire passing and main arch wire ligation.

[0022] Furthermore, a ligation hook 21 is processed on one side of the transverse section of the ligation wing 2, and a ligation notch 22 is processed on the other side; and a slide groove 23 is processed in the middle of the ligation wing 2, and a movable wing 4 is arranged in the slide groove 23. The movable wing 4 cooperates with the ligation notch 22 to form a ligation groove with a variable groove width, so as to form a continuous correction force on the main arch wire. The movable wing 4 is an optional component to meet the needs of precise control; and at the beginning of correction, due to the large amount of tooth deformation, the expected effect can be achieved by using a lingual bracket body.

[0023] In addition, a fracture 31 is cut on the auxiliary tube 3 corresponding to the middle slide groove 23 of the ligation wing. The fracture 31 and the side wall of the slide groove 23 are in the same plane, and the side wall is perpendicular to the central axis of the auxiliary tube 3, forming another reference.

[0024] The biggest feature of the utility model is that the bottom plate 1 can avoid the ridge of the lingual edge of the teeth when bonding, with a large adjustment margin and a reliable bonding surface, and can use the edges of the transverse section 11 and the longitudinal section 12 to form a reference, which is convenient for clinical judgment. The bottom surfaces of the transverse section 11 and the longitudinal section 12 of the bottom plate are processed with bonding lines.
