Abstract
Description
Technical Field
[0001] This utility model relates to an early correction bracket cheek tube kit, belonging to the field of medical device technology. Background Technology
[0002] Brackets are a common tool for orthodontic treatment. They are bonded to different teeth, and the archwire deforms to generate force to guide each tooth to move towards the target position. Different types of brackets include a base plate, bracket wings, and grooves. Traditional brackets use ligature wires to fix the steel wire, while self-ligating brackets are designed with locking clips to lock the archwire and complete the force to move the teeth.
[0003] Humans have two sets of teeth throughout their lives: deciduous teeth and permanent teeth. These teeth accompany the growth and development of the craniofacial region and perform oral functions. The replacement process of deciduous teeth with permanent teeth is very complex and closely related to normal craniofacial growth. The order of replacement of deciduous teeth with permanent teeth is as follows: the six-year molars of the upper and lower jaws erupt first, followed by the incisors. After that, the replacement of teeth in the mouth basically stops for 2 to 3 years. The position of early tooth eruption and the established occlusal relationship are very important for individual craniofacial development and functional movement.
[0004] However, the most direct contact part of the orthodontic bracket during tooth movement and force application is the bracket groove. The existing bracket cheek tube is designed based on the normal adult tooth alignment characteristics and cannot well adapt to the correction of the early tooth eruption position, resulting in poor early correction results.
[0005] Therefore, it is necessary to study existing early correction bracket cheek tube kits to address the aforementioned issues. Utility Model Content

Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.
[0049] According to the present invention, an early orthodontic bracket buccal tube set includes four buccal tubes 1 for attaching and correcting the six-year molars, wherein the six-year molars are the left and right six-year molars of the upper and lower jaws, namely, the upper right tooth 16, upper left tooth 26, lower left tooth 36 and lower right tooth 46 in the FDI tooth position representation.
[0050] It also includes twelve brackets 2 for bonding and correcting the central incisors, lateral incisors, and premolars. The central incisors refer to the left and right maxillary central incisors, namely, left maxillary central incisor 11, right maxillary central incisor 21, left mandibular central incisor 31, and right mandibular central incisor 41 in the FDI tooth position representation. The lateral incisors refer to the left and right maxillary lateral incisors, namely, left maxillary lateral incisor 12, right maxillary lateral incisor 22, left mandibular lateral incisor 32, and right mandibular lateral incisor 42 in the FDI tooth position representation. The premolars refer to the left and right maxillary premolars, namely, left maxillary premolar 14, right maxillary premolar 24, left mandibular premolar 34, and right mandibular premolar 44 in the FDI tooth position representation.
[0051] Existing orthodontic bracket and cheek tube kits are designed based on the characteristics of adult teeth. First, there are too many brackets and cheek tubes, and children have fewer teeth than adults when they replace their primary teeth, resulting in a waste of brackets and cheek tubes. More importantly, the size of the brackets and cheek tubes in existing orthodontic bracket and cheek tube kits, as well as the angle of the tube holes or grooves, do not match children's teeth, resulting in unsatisfactory orthodontic results in children.
[0052] In this utility model, such as Figure 1-3 As shown, the buccal tube 1 includes a buccal tube body 11 and a mesh base plate 12, wherein the mesh base plate 12 is a flat plate, an arc-shaped plate or a plate with a bend, the lower end of which is used to be pasted on the tooth surface, and the upper end is fixedly connected to the buccal tube body 11.
[0053] In a preferred embodiment, the lower surface of the mesh base plate 12 is mesh-like, which improves its bonding and fixing strength with the teeth.
[0054] The cheek tube 11 is provided with a tube hole 111 for accommodating the archwire, and a hook 13 is provided on the side of the cheek tube 11.
[0055] The tube hole 111 is a square hole, and the axis of the tube hole 111 is parallel to the upper surface of the mesh base plate 12.
[0056] Unlike the square holes in traditional cheek tubes, in this invention, such as Figure 3 As shown, the width w of the tube hole 111 is 0.5mm to 0.6mm, preferably 0.56mm, the height h is 0.7mm to 0.8mm, preferably 0.76mm, and the length of the tube hole 111 is 4mm to 6mm.
[0057] For ease of description, in this utility model, the state in which the upper surface of the mesh base plate 12 is in a horizontal plane is used as the description state.
[0058] Preferably, there is an angle θ between the square centerline of the cross-section of the pipe hole 111 and the vertical line, also known as the torque angle, such as... Figure 2 As shown.
[0059] Preferably, the included angle θ of the buccal tube hole 111 used for bonding the maxillary left and right six-year molars is 15 to 0 degrees; the included angle θ of the buccal tube hole 111 used for bonding the mandibular left and right six-year molars is 32 to 17 degrees.
[0060] The above-mentioned orifice size and angle settings are modified based on the characteristics of primary tooth replacement and combined with clinical experience. They are specifically designed for early orthodontic treatment during the primary tooth replacement process in children, and safeguard the smooth eruption of subsequent permanent teeth and the growth and development of the craniofacial region.
[0061] The hook 13 has the same structure as the hook 13 in the conventional cheek tube 1, and the hook 13 is used to fix the bowwire.
[0062] Preferably, the front end of the hook 13 is provided with a spherical protrusion to prevent the bowwire from falling off.
[0063] The bracket 2 includes a bracket base 21 and a bracket body 22 disposed on the bracket base 21, such as Figure 4-5 As shown.
[0064] The bracket base 21 is a flat plate, an arc-shaped plate, or a plate with bends. Its lower end is used to be pasted onto the tooth surface, and its upper end is fixedly connected to the bracket body 22.
[0065] In a preferred embodiment, the bracket body 22 is obliquely square, with a groove 221 in the middle for accommodating the archwire. The groove 221 is arranged longitudinally to accommodate the archwire.
[0066] The bracket body 22 has bracket ligation wings 222 on both sides. The bracket ligation wings 222 are curved wings and are used to fix the orthodontic archwire. Furthermore, the orthodontic archwire is bound and fixed by ligation wire or ligation rings placed on the wings.
[0067] In this utility model, the horizontal cross-section of the groove 221 is a parallelogram, and the acute angle of the interior angle of the parallelogram is α. Figure 4 As shown.
[0068] Furthermore, a torque groove 223 is provided on the bracket ligation wing 222. The torque groove 223 is arranged laterally, and the bottom of the torque groove 223 forms an angle β with respect to the upper surface of the bracket base 21. Figure 5 As shown.
[0069] Unlike traditional brackets 2, in this utility model, the width of the groove 221 is 0.5mm to 0.6mm, preferably 0.56mm; the depth of the groove 221 is 0.7mm to 0.8mm, preferably 0.76mm.
