Detailed Description

In the present invention, the term "and/or" is intended to cover all possible combinations and sub-combinations of the listed elements, including any one, any sub-combination, or all of the elements listed individually, without necessarily excluding other elements.

In the present invention, unless otherwise specified, the terms "first", "second", and the like are used to describe various elements and are not intended to define the positional relationship, the timing relationship, or the importance relationship of the elements, and such terms are used only to distinguish one element from another.

In the present invention, unless otherwise specified, the orientation or positional relationship indicated by the terms "front, rear, upper, lower, left, right" and the like is generally based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and is not to be construed as limiting the scope of the present invention.

Lingual brackets are a commonly used structure in lingual correction. The lingual bracket and the auxiliary structure thereof can realize effective control on the tooth in three-dimensional direction. The lingual bracket and the auxiliary structure thereof used in clinic at present are designed and manufactured by utilizing tooth data obtained by digital intraoral scanning and under the assistance of a computer. The lingual bracket is bonded to the lingual surface by a thermoplastic transfer tray in an indirect bonding manner. It should be appreciated that the lingual brackets of the last molars (e.g., second molars or third molars, etc.) of the upper and lower jaws are typically designed as hollow tube structures, commonly referred to as lingual tubes, for the purposes of facilitating placement of an archwire, etc. The lingual tube can be directly and fixedly connected to the lingual bracket base plate or the ring.

In clinic, the area of the lingual surface of the dental crown is small due to insufficient eruption or small clinical dental crown of the second lower molar of part of patients. In the related art, for example, the second molar crown is not sufficiently exposed in the vertical direction, and the height of the entire arch wire plane can be raised only in the occlusal direction, which, however, may cause problems such as occlusion interference, difficulty in applying force in correction, and the like.

Fig. 1 shows a schematic view of a lingual surface tube assembly of an exemplary embodiment of the present invention bonded to a lower right second molar. Fig. 1 shows the second premolar 102, the first molar 104 and the second molar 106 from left to right in that order. The second premolar 102 and the first molar 104 are respectively fixedly connected with a first bracket 103 and a second bracket 105 through a first bracket base plate 107 and a second bracket base plate 108. The lingual tube assembly 200 is bonded to the second molar 106 by a band ring 221. The lingual tube assembly 200 includes a lingual tube body 201, a connecting portion 211, and a band 221. Wherein, the belt ring 221 is sleeved on the crown of the second molar 106 and is connected with the lingual tube body 201 through the connecting part 211. The lingual tube body 201 is provided with a fabrication hole 206 for preventing the archwire slot 204 (see fig. 2) from being blocked. The second molar 106 in fig. 1 erupts a crown lingual surface area that is significantly smaller than the second premolar 102 and the first molar 104, so that the lingual tube body is fixed by means of band-loop bonding and through the connection part. Wherein, the size of the fixing surface formed by the fixed connection of the connecting part and the belt ring is smaller. As will be further described below. It should be understood that if the lingual tube body is directly fixed on the belt ring without lifting the height, the lingual tube body will directly press the gum on the lingual side of the second molar, and the belt ring may not be bonded in place, and even the lingual tube body and the belt ring may not be connected due to the large staggered distance in the vertical direction.

As shown in fig. 2, the lingual tube assembly 200 includes a lingual tube body 201, a connecting portion 211, and a fixing portion. Further, in the illustrated embodiment, the fixing portion is configured as a band 221. The lingual tube body 201 is of a hollow tube structure, a rectangular arch wire groove 204 penetrates through the inside of the lingual tube body 201, and a distal hook 208 is arranged at the tail end of the lingual tube body 201 and used for shielding the tail end of an arch wire (not shown) and for traction. A tooling hole 206 is provided at an end distal to the second molar. Opposite this end, a first end 203 is provided for fixed connection. It should be understood that first end 203 is a complete flat or curved surface that is an integral part of lingual tube body 201. In the related art, the first end is used for direct fixed attachment, such as welding, to the base plate or strap ring.

The connecting portion 211 is substantially a cylindrical structure, and includes a second end 212 fixedly connected to the belt ring 221 and a third end 213 fixedly connected to the first end 203. The outer surface of the connection portion 211 is smoothed to protect the oral cavity from scratches. In the illustrated embodiment, the second end 212 of the connecting portion 211 is smaller in size than the first end 203 of the lingual tube body 201.

The inner surface of the band 221 is provided with a texture 224 for increasing the adhesion with the second molar tooth. In addition, the inner surface of the band 221 is provided with a logo texture 228 for identifying the tooth site, for example, the logo texture 228 is shown as "7" to identify that the lingual surface tube assembly 200 is fitted with the seventh tooth, i.e., the second molar. Similarly, in other embodiments, other corresponding teeth may be identified by identifying the texture. In addition, the belt ring 221 is further provided with a positioning portion 226, and the positioning portion 226 can position the belt ring 221 when bonding is performed, so that accurate bonding is facilitated.

The dimension of the second end 212 of the connecting portion 211 of the columnar structure in fig. 2 is about 1/2 the dimension of the first end 203 of the lingual tube body 201. By adding the connecting part between the lingual tube body 201 and the fixing part, the lingual tube body can be far away from the gum of the second molar without affecting the placement of the arch wire. In addition, the position of the connecting part relative to the second molar is matched with the position of the adjacent bracket relative to the first molar, so that the lingual tube body can be prevented from being lifted, and the teeth can be effectively aligned.

In some embodiments, the second end of the connection is about 1/3 the size of the first end of the lingual tube body. Optionally, the second end has dimensions of 1.0 mm x 1.0 mm and the first end has dimensions of 3.0 mm x 3.0 mm. In other embodiments, the connecting portion is not a columnar structure, e.g., the connecting portion is configured as a truncated pyramidal structure. In various embodiments, the connecting portion may be adaptively configured in different shapes according to different requirements of the tooth arrangement, such as the length, relative angle, relative height, etc. of the connecting portion.

In some embodiments, the length of the connection portion is set in a range of 0.4 mm to 4.0 mm. Further, the length of the connecting portion is in a range of 0.5 mm to 3.0 mm. The length of the connecting portion can be set within a smaller range according to clinical needs.

In the illustrated embodiment, the lingual tube assembly 200 is integrally formed by 3D printing.

In alternative embodiments, the retainer portion is configured as a base plate or other structure suitable for retaining on a tooth.

According to the embodiment of the utility model, the connecting part is arranged, so that the second molar is accurately controlled on the basis of the ideal tooth arrangement and the ideal arch wire plane, and meanwhile, the gum is not pressed, and effective correction is realized.
