Description

Technical Field

[0001] This utility model belongs to the field of dental orthodontic technology, and specifically relates to a molar bracket. Background Technology

[0002] Orthodontic treatment often uses two to three molars on both sides as anchor points for the archwire to stabilize it and generate corrective torque, thus correcting the anterior teeth. Conversely, the molars are also constrained by the fixed archwire and cannot make corresponding physiological movements during biting, affecting the alignment process of the entire set of teeth and the establishment of individualized occlusion for the patient.

[0003] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0004] The purpose of this invention is to design a molar bracket that allows for proper floating of the molars.

[0005] The technical solution of this utility model is implemented as follows: a molar bracket, characterized in that: it includes a bracket base and a tube wing, the bracket base has a base plate that can be bonded to the tooth surface and a ligation wing protruding from one side of the base plate, the ligation wing facing the other side of the base plate and having a sliding groove in the middle; the tube wing has a through hole for passing an archwire, and has a pin on one side and a traction hook and / or ligation hook on the other side, which is slidably inserted into the sliding groove by means of the pin, and the ligation hook is paired with the ligation wing for ligation with a rubber ring.

[0006] The pins extend from the bottom surface of one side of the tube wing, and the ligature hooks extend from the top surface of the other side of the tube wing, forming a misalignment.

[0007] The perforated section on the tube wing is a quadrilateral structure, and the end of the insert is provided with a limit hook, which is used to constrain it in the groove.

[0008] This invention cleverly utilizes tube wings to position the archwire. The quadrilateral perforations ensure that the archwire has a specific angle of torque. The tube wings are secured to one side of the bracket with rubber rings to maintain positional stability, while allowing for physiological movement of the molars during biting, thus promoting healthy growth of the alveolar bone during orthodontic treatment. It features a unique design, reasonable structure, and comfortable, non-stiff wearing experience. Attached Figure Description

[0016] Reference Figure 1 , Figure 2 and Figure 3 The molar bracket includes a bracket seat 1 and a tube wing 2. The bracket seat 1 has a base plate 11 and a ligating wing 12. The bottom surface of the base plate 11 is processed with adhesive texture so as to bond the bracket seat to the tooth surface of the molar. The ligating wing 12 is located on one side of the base plate and faces the other side of the base plate. As shown in the figure, the adhesive part of the ligating wing 12 is located on the lower side of the base plate, while the ligating barb faces the upper side of the base plate.

[0017] The ligature wing 12 has a groove 13 in the middle and an extended blocking edge 131 is machined on the surface of the base plate 1. The blocking edge 131 helps the groove 13 to constrain the tube wing 2.

[0018] The tube wing 2 has a through hole 21 for threading the archwire. The through hole 21 has a quadrilateral cross-section to generate the torque required for orthodontic treatment of the archwire. A pin 22 is provided on one side of the tube wing 2, and a ligation hook 23 is provided on the other side. The ligation hook 23 is slidably inserted into the groove 13 with the help of the pin 22. The ligation hook 23 is paired with the ligation wing 12 for ligation by the rubber ring and to maintain the stability of the relative position of the archwire and the bracket seat 1, without affecting the physiological activity of the molars during occlusion.

[0019] Furthermore, the insert 22 extends from the bottom surface of one side of the tube wing 2, and the ligation hook 23 extends from the top surface of the other side of the tube wing 2, forming a misalignment. In addition, the end of the insert 22 of the tube wing is provided with a limiting hook 221, which is used to restrain the insert in the groove 13 to prevent it from coming out. Furthermore, the tube wing 2 and the ligation wing 12 also form a groove with an adjustable width, which can also be used to ligate the archwire when needed, but it is not as effective as the quadrilateral perforation 21 in generating continuous torque.

[0020] In clinical practice, the assembled molar brackets can be operated as a whole or separately. Operating them separately makes it easier to pass the archwire. For example, the bracket 1 is bonded to the tooth surface of the molar, the tube wing 2 with the archwire inserted is then assembled into the bracket 1, the limiting hook 221 is folded out to both sides, and finally, a rubber ring is used to ligate it to maintain the stability of the archwire position.

[0021] Depending on the need, the ligation hook 23 can be replaced by a traction hook. The two have basically similar functions, or the ligation hook 23 and the traction hook can be designed side by side to accommodate different purposes.
