Description

An easy-to-identify high-strength orthodontic bracket and its accurate identification method

technical field

The invention relates to the technical field of dental orthodontics, in particular to an easy-to-identify high-strength orthodontic bracket and an accurate identification method thereof.

Background technique

Brackets are generally made of materials such as metal or ceramics. In orthodontic treatment, special adhesives are usually used to fix them on the surface of the teeth to accommodate and fix the orthodontic wires, and transmit the orthodontic force to the teeth, so as to achieve The effect of orthodontic treatment. In precise orthodontics, teeth of different tooth positions need to be corrected with different specifications of brackets, and the brackets are relatively small. It is usually difficult for doctors to accurately identify and distinguish brackets of different tooth positions when using them, which leads to the use of confusion.

In order to solve this problem, bracket developers usually add some marks on the bracket to mark the use position of the corresponding bracket. E.g:

The Chinese patent discloses an orthodontic bracket tooth position identification (patent number 2015204104847), which is characterized in that a laser is used to permanently mark the bottom of each bracket. The logo is composed of a right-angled frame and a single Arabic numeral. The right-angled frame represents each tooth position interval, and a single Arabic numeral indicates the number of teeth in the tooth position interval. Although this technology allows clinical medical staff to easily and conveniently identify the corresponding tooth position of each bracket, it can avoid the bonding error of brackets, so that the dentition of oral malocclusion can be corrected according to the expected requirements, and the expected correction effect can be achieved. However, since the specific mark is made on the bottom surface of the bracket bottom plate, when the bracket is bonded to the tooth, the bracket bottom plate is in contact with the surface of the tooth, and the mark on the bottom surface of the bottom plate will be covered, which is not only inconvenient It is not intuitive to distinguish and check after completion, so it is less practical.

The Chinese patent discloses a lingual bracket with an identification function (Patent No. 2018217532964), which is characterized in that the identification body 5 includes a connecting portion 51 that surrounds the bracket body 2 and abuts against the identification groove 27. The connecting portion 51 is made of elastic material, such as a rubber ring, etc. The identification body 5 also includes an identification portion 52 connected to the connecting portion 51. The identification portion 52 is in the shape of a sheet and abuts on the top surface of the cover plate 3. The identification portion 52 is engraved with numbers. , and the identification of the lingual bracket is realized through the number and color. The peripheral wall of the identification portion 52 is connected to the connecting portion 51 through an elastic line 53, and the elastic line 53 is made of rubber. Before use, the connecting part 51 is connected in the marking groove 27, the marking part 52 is in contact with the top surface of the cover plate 3, and the marking part 52 and the connecting part 51 are tightened by the design of the elastic wire 53, so that the marking body 5 can be Attaches to lingual brackets. This technology realizes the identification function by placing a new identification mechanism (identification body 5) on the bracket body. Since the bracket body itself is a very small structure, it is necessary to add such a complex structure to such a small structure. It not only increases the manufacturing process and cost of brackets, but also is not beautiful, and also makes the operation time-varying for doctors to be cumbersome, so the practicability is poor.

The Chinese patent discloses an orthodontic bracket with a positioning mark (Patent No. 2019210290259), which is characterized in that the positioning mark is arranged on the surface of the bracket. Since the bracket itself is relatively small, only the surface of the bracket is provided with depressions or The raised logo structure, and the color of the concave or convex logo structure is close to the color of the bracket body, and the color difference is not obvious, especially in the ceramic bracket, because the ceramic bracket itself is a translucent material, it is not easy to see. Without the logo, it is not easy to identify, that is, there is a problem that the logo is difficult to identify. In order to further solve this problem, although the positioning mark can be painted with paint to make its color different from its body part, the color mark mostly uses pigments, which also has a certain impact on physical health and is not practical and scientific.

The Chinese patent discloses an orthodontic self-locking bracket and an identification method (Patent No. 2018106619973), which is also characterized in that the first identification structure 22 is arranged on the upper surface of the bracket. Since the bracket itself is relatively small, it is only The surface of the bracket is provided with a concave or convex identification structure, and the color of the concave or convex identification structure is close to the color of the bracket body, and the color difference is not obvious, especially in the ceramic bracket, because the ceramic bracket itself is a kind of The semi-transparent material cannot see the logo at all, and it is not easy to identify, that is, there is also the problem of difficult identification of the logo.

Therefore, in order to be more convenient for doctors to identify and use, more effective improvements should be made to the positioning and identification structure of orthodontic brackets.

In addition, in ceramic brackets, there is a common problem of being easily broken and fragile. The main reason is that the structural design of the bracket body is unreasonable. Even metal brackets have the problem of easy deformation. Therefore, in order to further strengthen the brackets The strength of the groove also needs to be more effectively improved for the overall structure of the existing orthodontic brackets.
