Description

Technical Field

[0001] The present application relates to the technical field of orthodontics, and in particular to an orthodontic gingival anti-pressure device. Background Art

[0002] Orthodontic brackets are accessories used in orthodontic treatment. They are attached to the surface of teeth and are used to fix orthodontic archwires to adjust the position of teeth by gradually applying force.

[0003] During the process of orthodontic tooth correction, when it is necessary to retract the upper and lower anterior teeth and close the gap, more than 90% of doctors will choose the sliding method. For example, the Chinese patent with the announcement number CN219439481U discloses an orthodontic gum pressure-proof structure, including a traction member and an anti-pressure member connected and fixed to the arch wire. During installation, the anti-pressure structure is arranged at the corner of the dental arch, and the traction member and the anti-pressure member are arranged on both sides of the canine. The anti-pressure structure also includes an elastic stretching member, one end of which is hung on the traction member and the other end is hung on the hook of the bracket. The anti-pressure member is located between the hook and the traction member, and the traction member is pressed on the anti-pressure member. The anti-pressure member includes an anti-pressure member body, and the body is provided with a stabilizing arm on one side of the canine. The body is provided with a limiting groove for the elastic stretching member to be pressed and embedded, so as to prevent the elastic stretching member from slipping off the anti-pressure member. During installation, the stabilizing arm is against the tooth surface between the canine bracket and the gums, so that the anti-pressure member is supported by the tooth surface, thereby improving the stability of the anti-pressure member.

[0004] Through understanding of relevant technologies, since elastic stretching parts are generally connected between traction parts and brackets, they mainly play the role of bringing teeth closer together or preventing gaps between teeth. However, since the elastic stretching parts are in a stretched state, they are easy to contact the surface of the gums. The gums become red and swollen due to the pressure of the elastic stretching parts, and sink into the alveolar bone to cause inflammation. Therefore, anti-pressure parts appear in the above-mentioned related patent technologies. The anti-pressure parts have a complex structure when actually used, and the height of the limit groove on the anti-pressure part body is not adjustable. During installation, if the inclination of the elastic stretching part changes, the limiting effect of the limit groove on the elastic stretching part is not good, and the elastic stretching part is easy to fall out of the limit groove, resulting in a weak user experience. Utility Model Content

[0005] The purpose of the utility model is to solve the defects of the prior art and provide an orthodontic gum pressure prevention device.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An orthodontic gum pressure prevention device is installed on a dental appliance, the dental appliance comprises brackets fixed on teeth, archwires tied to the outside of a plurality of brackets, and a traction hook connected to the archwire;

[0008] Orthodontic gingival anti-pressure devices include:

[0009] Anchor pins are implanted in the posterior teeth area;

[0010] An elastic stretching piece, one end of which is connected to the support nail, and the other end of which is connected to the traction hook;

[0011] A flexible member, one end of which is connected to the bracket and the other end of which extends to one side of the elastic stretch member;

[0012] The flexible member can be deflected toward one side of the oral cavity wall of the human body so that the elastic stretching member is separated from the gum wall.

[0013] Through the above technical scheme, in order to protect the posterior teeth support, clinical doctors implant support pins in the posterior teeth area. During the period of orthodontic treatment, when the support pins are used to retract the anterior teeth by sliding, the elastic stretching member will compress the gingival tissue. The present application installs a flexible member on the bracket. After the flexible member is bent, it will not be reset without the action of external force. Therefore, the present application uses the characteristics of the flexible member to offset its free end toward one side of the human oral wall during installation. After the flexible member is offset, it can drive the elastic stretching member to separate from the gingival wall, thereby avoiding the problem of redness, swelling and inflammation of the gums caused by the elastic stretching member compressing the gums.

[0014] Through the above technical solution, the end of the arch wire generally extends to the position of the posterior tooth area. After the protective ball head is provided at the end of the arch wire, the problem of the end of the arch wire contacting the oral skin and causing damage to the oral skin can be avoided.

[0015] Furthermore, the elastic stretching member is in a stretched state between the anchoring nail and the traction hook, and the direction of the pulling force generated by the elastic stretching member on the arch wire through the traction hook is toward the distal surface of the human incisor.

[0016] Through the above technical solution, the anchorage pins implanted in the posterior teeth area are used as the force fulcrum, and the installed elastic tensile member applies tension to the arch wire, and the sliding method is used to retract the anterior teeth to achieve the purpose of oral orthodontics.

[0017] Furthermore, the flexible member is formed by twisting multiple oral ligature wires, and one end of the flexible member away from the bracket is bent to form a limiting hook, which abuts against one side of the elastic stretching member. The limiting hook can be offset toward one side of the human oral wall to separate the elastic stretching member from the gum wall.

[0018] Through the above technical solution, the more the number of oral ligature wires is, the higher the strength of the flexible member is, and the length of the oral ligature wire is controllable, which is suitable for use with elastic stretching members at different positions and different inclinations.

[0019] Furthermore, the material of the protective ball head is resin.

[0020] Furthermore, the elastic stretching member is a rubber chain.

[0021] Furthermore, the length of the flexible member is greater than the distance between the bracket and the elastic tensile member.

[0022] Furthermore, one end of the flexible member away from the bracket is an arc end.

[0023] Through the above technical solution, the end of the flexible member away from the bracket is a free end. After the free end is designed as an arc end, the problem of oral skin being damaged due to touching the oral skin is avoided.

[0024] The beneficial effects of the present application are as follows: 1. When the implant support nail of the present application uses the sliding method to retract the front teeth, the elastic stretching member will compress the gingival tissue. The present application installs a flexible member on the bracket or archwire. The present application uses the characteristics of the flexible member to deviate its free end toward one side of the human oral cavity wall during installation. After the flexible member is deviated, it can drive the elastic stretching member to separate from the gingival wall, thereby avoiding the problem of the elastic stretching member compressing the gingiva, causing gingival redness, swelling and inflammation. The flexible member itself has a simple structure and is easy to install. The limit hook at its end is suitable for use with elastic stretching members at different positions and different inclinations, and the problem of the elastic stretching member falling out of the limit hook will not occur.

[0025] 2. A protective ball head is provided at the end of the arch wire of the present application, which can prevent the end of the arch wire from contacting the oral skin and causing damage to the oral skin. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, the orthodontic gingival anti-pressure device includes an anchor pin 5 implanted in the posterior tooth area, an elastic stretch member 6 connected to the anchor pin 5 at one end and to the traction hook 4 at the other end, and a flexible member 7 connected to the bracket 2 at one end and extending to one side of the elastic stretch member 6 at the other end, wherein the flexible member 7 can be offset toward one side of the human oral cavity wall to separate the elastic stretch member 6 from the gingival wall.

[0036] Among them, the elastic stretching member 6 is preferably a rubber chain, the length of the flexible member 7 is greater than the distance between the bracket 2 and the elastic stretching member 6, the elastic stretching member 6 is in a stretched state between the support nail 5 and the traction hook 4, and the direction of the tension generated by the elastic stretching member 6 on the arch wire 3 through the traction hook 4 is toward the distal surface of the human incisor, with the support nail 5 implanted in the posterior tooth area as the force fulcrum. After installation, the elastic stretching member 6 applies tension to the arch wire 3, and uses the sliding method to retract the anterior teeth to achieve the purpose of oral orthodontics.

[0037] Specifically, refer to Figure 1 , Figure 2 The end of the flexible member 7 away from the bracket 2 is bent to form a limit hook 8, which abuts against one side of the elastic stretch member 6 to prevent the elastic stretch member 6 from detaching. The limit hook 8 can be offset toward one side of the human oral cavity wall to separate the elastic stretch member 6 from the gum wall.

[0038] The flexible member 7 is formed by twisting a plurality of oral ligation wires 71. The oral ligation wires 71 generally have a diameter of about 0.3 mm and are two or more in number. The more oral ligation wires 71 there are, the higher the strength of the flexible member 7 is. Moreover, the length of the oral ligation wires 71 is controllable, and is suitable for use with elastic stretch members 6 at different positions and with different inclinations.

[0039] Through the above technical scheme, in order to protect the posterior teeth support, the doctor implants the support nail 5 in the posterior teeth area clinically. During the period of tooth correction, when the implanted support nail 5 uses the sliding method to retract the front teeth, the elastic stretching member 6 will compress the gingival tissue. The present application installs the flexible member 7 on the bracket 2 or the arch wire 3. After the flexible member 7 is bent, it will not be reset without the action of external force. Therefore, the present application uses the characteristics of the flexible member 7 to offset its free end toward one side of the human oral wall during installation. After the flexible member 7 is offset, it can drive the elastic stretching member 6 to separate from the gingival wall, thereby avoiding the problem of the elastic stretching member 6 compressing the gums and causing redness, swelling and inflammation of the gums; the flexible member 7 itself has a simple structure and is easy to install. The limit hook 8 at its end is suitable for the use of elastic stretching members 6 at different positions and different inclinations, and the problem of the elastic stretching member 6 escaping from the limit hook 8 will not occur.

[0040] In addition, the end of the flexible member 7 away from the bracket 2 is an arc end, and the end of the flexible member 7 away from the bracket 2 is a free end. After the free end is designed as an arc end, the problem of oral skin being damaged due to touching the oral skin is avoided.

[0041] Example 2

[0042] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a protective ball head 9 is provided at the end of the arch wire 3. The material of the protective ball head 9 is preferably resin. The end of the arch wire 3 generally extends to the position of the posterior tooth area. After the protective ball head 9 is provided at the end of the arch wire 3, the problem of the end of the arch wire 3 contacting the oral skin and causing damage to the oral skin can be avoided.
