Description

Technical Field

[0001] The utility model belongs to the technical field of dental orthodontics, and particularly relates to a bracket fixing piece for bracket installation. Background Art

[0002] Tooth correction covers a wide range. Generally, it refers to the treatment process of trimming uneven tooth arrangement, abnormal tooth shape, and abnormal tooth color through oral technical means. There are various methods for tooth correction, such as resin veneers, porcelain veneers, porcelain crowns, orthodontics, etc. Among them, the bracket is an important component of the fixed orthodontic technology, which is directly bonded to the tooth crown surface with an adhesive, and the arch wire applies various types of corrective forces to the teeth through the bracket. Currently, when installing the bracket, a bracket fixing device is borrowed for installation to improve the installation efficiency of the bracket. However, the positioning accuracy of the bracket fixing device on the market for the bracket is poor, which easily causes errors in the connection position between the bracket and the tooth surface.

[0003] The utility model with the application number CN201820623826.7 discloses a bracket fixing device, which mainly includes a base and a hook rod part connected to the base. Among them, the base is provided with an opening, an embedding part is provided at the lower edge of the opening, and a positioning groove is provided at the periphery of the embedding part. The hook rod part extends horizontally from the top edge of the base by an appropriate length and is inclined forward at an appropriate angle. The above bracket fixing device adheres the bracket to the bracket fixing device, and then fixes the bracket to the tooth surface of the patient through the bracket fixing device. Fixing the bracket to the bracket fixing device in this way by adhesion has poor fixing accuracy of the bracket, which easily causes errors in the connection position between the bracket and the tooth surface.

Detailed Embodiment

[0021] The present utility model will be further described below with reference to the drawings.

[0022] A bracket fixing member for bracket installation. There is a bracket fixing cavity 1 in the bracket fixing member. The bracket fixing cavity 1 is used to fix the bracket 10 within the bracket fixing member. The bracket fixing member is provided with a tooth positioning surface 2. By means of the tooth positioning surface 2, the bracket fixing member is positioned and placed on the top of the tooth, so that the bracket is fixed to the tooth surface.

[0023] The tooth positioning surface 2 is a plane and is used to abut the bracket fixing member against the top of the patient's tooth being held. The bracket fixing cavity 1 is located below the tooth positioning surface 2, which is convenient for setting the bracket 10 fixed in the bracket fixing cavity 1 towards the tooth surface, so as to facilitate fixing the bracket 10 on the patient's tooth surface. And this bracket fixing member fixes the bracket through the bracket fixing cavity 1, without using glue to fix the bracket on the bracket fixing member, which is convenient for separating the bracket from the bracket fixing member after the bracket installation is completed.

[0024] There is an installation gap 5 between the bracket fixing cavity 1 and the tooth positioning surface 2, which separates the bracket fixing cavity 1 from the tooth positioning surface 2, facilitating placing the bracket 10 into the bracket fixing cavity 1.

[0025] On both sides of the installation gap 5, there are limit plates 6. The distance between the limit plates 6 is the same as the width of the bracket fixing cavity 1, so that the limit plates 6 have a certain limiting effect on the bracket 10.

[0026] There is an opening 7 on the limit plate 6. Through the setting of the opening 7, it is convenient to apply glue to the end face of the bracket 10, so as to facilitate fixing the bracket 10 on the patient's tooth surface. At the same time, the opening 7 can also facilitate the overflow of the glue, preventing excessive glue between the tooth surface and the bracket 10.

[0027] On the end face of the bracket fixing cavity 1, an end face positioning surface 3 is formed. The end face positioning surface 3 abuts against the arch wire 11 on the bracket 10, so as to position and arrange the bracket 10 in the bracket fixing cavity 1 through the cooperation of the end face positioning surface 3 and the arch wire 11.

[0028] The lower edge of the limit plate 6 includes a height positioning surface 4 and an opening inclined surface 12 that are connected to each other. The height positioning surface 4 abuts against the arch wire 11 on the bracket 10, so as to position and arrange the bracket 10 in the bracket fixing cavity 1 through the cooperation of the height positioning surface 4 and the arch wire 11.

[0029] The height positioning surface 4 and the end face positioning surface 3 are vertically arranged. The bracket 10 is positioned and arranged in the bracket fixing cavity 1 through the cooperation of the height positioning surface 4, the end face positioning surface 3 and the arch wire 11, ensuring the position accuracy of the bracket 10 relative to the bracket fixing member, so as to facilitate more accurately fixing the bracket 10 on the patient's tooth surface.

[0030] The opening inclined surface 12 is inclined relative to the height plane 4. Through the setting of the opening inclined surface 12, it is convenient to form the opening 7 on the limit plate 6.

[0031] An opening groove 8 is provided at the top of the bracket fixing member. The opening groove 8 communicates with the bracket fixing cavity 1. The opening groove 8 can be used to observe the bracket 10 fixed in the bracket fixing cavity 1. Similarly, it can also be used to overflow the glue for connecting the bracket 10 and the tooth surface.

[0032] The thickness of the opening groove 8 is less than the thickness of the bracket, preventing the opening groove 8 from being too large and causing the bracket 10 to slide out of the bracket fixing cavity 1.

[0033] A connecting block 9 is provided at the top of the bracket fixing member. The connecting block 9 is used to connect with an external bracket, so as to facilitate the fixing of this bracket fixing member on the external bracket, and thus facilitate the movement of this bracket fixing member through the external bracket.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0035] Although this text uses more terms corresponding to the reference numerals in the drawings, the possibility of using other terms is not excluded; the use of these terms is only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
