Description

Technical Field

[0001] The utility model relates to the technical field of orthodontic medical devices, and particularly relates to an orthodontic bracket for reducing friction. Background Technique

[0002] The bracket is an important component of the fixed orthodontic technique. It is directly bonded to the surface of the tooth crown with an adhesive. The arch wire applies various types of orthodontic forces to the teeth through the bracket. Its main function is to fix the arch wire, so that the arch wire can play a better role, transmit the orthodontic force, and control the three-dimensional movement of the teeth at one time to achieve the purpose of orthodontic treatment.

[0003] The existing brackets usually adopt the double-wing ligation type during the orthodontic treatment. And because the notch of the main arch wire slot is basically a right angle, the line contact between the arch wire and the notch of the main arch wire slot will generate a large frictional resistance and indentation resistance, resulting in difficult control of the orthodontic force. In addition, the groove of the double-wing bracket is relatively wide, which limits the movement of the teeth, especially the inclined movement of the canine teeth, reducing the orthodontic effect and prolonging the treatment cycle. Therefore, it is necessary to design an orthodontic bracket for reducing friction. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an orthodontic bracket for reducing friction, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an orthodontic bracket for reducing friction, including a bracket, the bracket is provided with a ligation wing, an auxiliary arch wire groove ligation wing, a main arch wire groove and a bracket base, a ligation groove is arranged below the ligation wing, and an auxiliary wire groove is arranged below the auxiliary arch wire groove ligation wing. It is characterized in that: corresponding guiding bevels are arranged on both sides of the opening end of the main arch wire groove, a transition groove is formed between the guiding bevels of the main arch wire groove and is horizontally arranged, and an auxiliary arch wire groove penetrating through the auxiliary arch wire groove ligation wing is further arranged on the auxiliary arch wire groove ligation wing.

[0006] Preferably, the ligation groove and the auxiliary wire groove are semi-open arc grooves.

[0007] Preferably, the auxiliary arch wire groove is a fully enclosed groove and can accommodate a circular arch wire with a maximum diameter of 0.40 mm.

[0008] The utility model has the following beneficial effects:

[0009] By setting chamfers on the mesial and distal opening sides of the main arch wire groove, the contact between the arch wire and the side wall of the main arch wire groove is changed from "line contact" to "point contact", reducing the contact area between the arch wire and the groove of the main arch wire groove during the inclined movement of the teeth, reducing the friction between the two, saving anchorage, and improving the efficiency of tooth movement; by setting transition grooves on the main arch wire groove, it is convenient for quickly positioning the bracket position during clinical operation, ensuring that the bracket is in the middle position of the tooth, making it easier for industry doctors to accept and master. At the same time, the design of the single ligation wing reduces the width of the groove of the main arch wire groove in the mesial-distal direction, making the overall volume of the bracket smaller, causing less irritation to the patient's oral cavity, and being suitable for clinical orthodontic applications for patients with smaller teeth;

[0010] Through the setting of the semi-open arc grooves of the ligation groove and the auxiliary wire groove, the ligation loop fixed on them will not be stressed and fall off the groove, so that the arch wire fixed on the main arch wire groove 7 is not easy to fall off;

[0011] Through the setting of the auxiliary arch wire groove, a circular space for accommodating the circular arch wire is increased, realizing a double groove system, facilitating double wire correction, vertically controlling the dental arch, and adjusting the dental arch form to make the orthodontic effect more perfect. At the same time, the fully enclosed structure does not require a ligation loop to fix after threading the arch wire during clinical use, and the circular arch wire will not be dislocated, making the auxiliary arch wire groove have a self-locking function, and the circular groove can perfectly match the circular arch wire.

[0016] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Such as Figures 1-3As shown in the figure, an orthodontic bracket for reducing friction includes a bracket 1. The bracket 1 is provided with a ligation wing 2, an auxiliary arch wire groove ligation wing 4, a main arch wire groove 7 and a bracket base 10. A ligation groove 3 is provided below the ligation wing 2, and an auxiliary wire groove 5 is provided below the auxiliary arch wire groove ligation wing 4. It is characterized in that: corresponding guiding chamfer angles 8 are provided on both sides of the open end of the main arch wire groove 7. A horizontally arranged transition groove 9 is formed between the guiding chamfer angles 8 of the main arch wire groove 7. The auxiliary arch wire groove ligation wing 4 is also provided with an auxiliary arch wire groove 6 penetrating through the auxiliary arch wire groove ligation wing 4.

[0018] By setting the chamfer angles 8 on the mesial and distal open sides of the main arch wire groove 7, the contact between the arch wire and the side wall of the main arch wire groove 7 is changed from "line contact" to "point contact", reducing the contact area between the arch wire and the groove of the main arch wire groove 7 when the tooth moves obliquely, reducing the friction between the two, saving anchorage and improving the efficiency of tooth movement; by setting the transition groove 9 on the main arch wire groove 7, it is convenient for quickly positioning the position of the bracket 1 during clinical operation, ensuring that the bracket 1 is in the middle position of the tooth, making it easier for dentists in the industry to accept and master. At the same time, the design of a single ligation wing reduces the width of the groove of the main arch wire groove 7 in the mesial-distal direction, making the overall volume of the bracket 1 smaller, causing less irritation to the patient's oral cavity, and being suitable for clinical orthodontic applications for patients with smaller teeth;

[0019] In one embodiment, the ligation groove 3 and the auxiliary wire groove 5 are semi-open arc-shaped grooves.

[0020] Through the setting of the semi-open arc-shaped grooves of the ligation groove 3 and the auxiliary wire groove 5, the ligation loop fixed on them will not be stressed and fall out of the groove, so that the arch wire fixed on the main arch wire groove 7 is not easy to fall off.

[0021] In one embodiment, the auxiliary arch wire groove 6 is a fully enclosed groove, which can accommodate a round arch wire with a maximum diameter of 0.40 mm.

[0022] Through the setting of the auxiliary arch wire groove 6, the circular space for accommodating the round arch wire is increased, realizing a double groove system, facilitating double wire correction, vertically controlling the dentition, and adjusting the arch form, making the orthodontic effect more perfect. At the same time, the fully enclosed structure does not require a ligation loop to fix after threading the arch wire during clinical treatment, and the round arch wire will not be displaced, making the auxiliary arch wire groove 6 have a self-locking function, and the round groove and the round arch wire can be perfectly matched.

[0023] When the utility model is in use, the position of the bracket 1 is located through a locator, and then the bracket 1 is adhered to the tooth surface by an adhesive. The above steps need to be repeated for all teeth to be corrected. Then, an arch wire is passed through the main arch wire groove 7 provided on the bracket 1. Due to the two obliquely arranged angles 8 on the two sides of the main arch wire groove 7, the arch wire forms two-point connection on the main arch wire groove 7. At the same time, a ligature loop can also be used to fix the arch wire through the ligature groove 3 and the auxiliary wire groove 5, so that the arch wire is locked and will not fall off the bracket 1 due to external force. In the later stage, a round arch wire can also be directly fixed through the auxiliary arch wire groove 6 and the ligature groove 3. Moreover, the round shape of the auxiliary arch wire groove 6 can be perfectly adapted to the round arch wire. At the same time, due to the fully enclosed structure of the auxiliary arch wire groove 6, there is no need to use a ligature loop for fixation, and the arch wire will not fall off under the action of external force either.

[0024] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model.
