Description

Technical Field

[0001] The utility model relates to the technical field of oral medicine, in particular to a novel traction hook used in oral orthodontics. Background Art

[0002] The current mainstream traction hook products are mainly used in the orthodontic industry. During the process of tooth correction, for patients who need to close the gap between teeth (such as the closure of the extraction gap for patients who need tooth extraction), the gap is closed while preventing the teeth from tipping over during the movement process or correcting the tipping that has already occurred in time. The principle of its implementation is to bond two traction hooks to the two teeth at both ends of the gap respectively, and by hanging a traction chain-like rubber band on the traction hook, a long-term traction force is applied to the teeth, thereby realizing the movement of the teeth. The traction force acts close to the resistance center under the teeth, so that the teeth can be moved horizontally and effectively prevent the teeth from tipping over.

[0003] The current mainstream towing hooks have the following disadvantages:

[0004] 1. Since the end of the mainstream traction hook is hook-shaped, after the chain-shaped rubber band is hung, the plane of the rubber band intersects vertically with the teeth, and the lip and cheek mucosa have a strong foreign body sensation, poor comfort, and are prone to cause ulcers.

[0005] 2. The side of the mainstream traction hook is flat. After it is bonded to the tooth, the upper half is close to the surface of the tooth. Since the gums generally protrude more than the surface of the teeth, the lower half will press on the gums, which is uncomfortable and easy to cause ulcers.

[0006] 3. The mainstream traction hook is in the shape of a narrow stick, so when it is bonded to the tooth surface, the bonding area is small and it is easy to fall off, causing emergency treatment, increasing the number of follow-up visits, and affecting the correction process. Utility Model Content

[0007] Therefore, the technical problem to be solved by the utility model is to overcome the defects of the prior art that the traction hook is easy to fall off from the teeth and partially contacts with the gums to cause ulcers, thereby providing a new traction hook used in oral orthodontics.

[0008] In order to solve the above problems, the utility model provides a new type of traction hook used in oral orthodontics, comprising:

[0009] a bonding section having a concave surface;

[0010] A traction force transmission section, wherein a first end is connected to the bonding section, a second end extends in a direction away from the bonding section, and a cross-sectional shape of the first end is an arc;

[0011] The hanging and traction section is connected to the second end of the traction force conducting section. The hanging and traction section has an H-shaped cross section and is staggered with the bonding section in the height direction.

[0012] Optionally, the surface of the bonding section is a curved mesh structure with a width w1 of 4-6 mm and a height h1 of 3 mm.

[0013] Optionally, the shape of the recessed surface of the bonding section is circular, the central diameter of the recessed surface is 3mm, and there are side wings on both sides of the bonding section, and the width of the side wings is 1-3mm; the end face of the bonding section facing away from the recessed surface is arc-shaped, the central thickness of the bonding section is 1mm, and the edge thickness is 0.5mm.

[0014] Optionally, the side wing surface of the bonding section is a mesh structure.

[0015] Optionally, the cross-sectional shape of the traction force conducting section is semicircular, and the arc-shaped outer edge of the semicircle faces away from the bonding section.

[0016] Optionally, the diameter d1 of the traction force conducting section is 2 mm.

[0017] Optionally, a connecting portion connected to the traction force conducting section is provided on one side of the hanging traction section, and a hemispherical head is connected to the other side through a column.

[0018] Optionally, the distance L between the connecting portion and the head is 0.8 mm, and the thickness dimension w2 of the traction section is 2.3 mm.

[0019] Optionally, the diameter d2 of the head of the hanging and traction section is 2 mm, and the thickness g is 0.5 mm.

[0020] The utility model has the following advantages:

[0021] The utility model provides a novel traction hook for use in oral orthodontics, comprising: a bonding section, a traction force transmission section and a hanging traction section. The bonding section has a concave surface. The first end of the traction force transmission section is connected to the bonding section, and the second end extends in a direction away from the bonding section, and the cross-sectional shape of the first end is an arc. The hanging traction section is connected to the second end of the traction force transmission section, and the cross-sectional shape of the hanging traction section is H-shaped, and is staggered with the bonding section in the height direction.

[0022] The bonding section in the utility model adopts a concave surface structure design, so that the contact area after bonding is larger and more firm, which reduces temporary re-visits caused by the traction hook falling off during the tooth correction process, avoids the correction cycle being affected by the traction hook falling off, and reduces costs. The traction force transmission section adopts an arc design, so that the middle and lower sections of the traction hook can avoid the protruding gums during use, and prevents the gums from being compressed during the correction process and causing oral ulcers. The hanging traction section structure adopts an H-shaped design, so that during clinical use, the structural plane is parallel to the teeth, reducing the patient's foreign body sensation in the mouth, reducing the wear on the side walls of the mouth, and reducing the probability of oral ulcers. In addition, due to the segmented design, the thickness of the mesh bottom is different, and it can be used in combination with the bracketless invisible correction window design.

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, a new type of traction hook applied to orthodontics is provided, including:

[0033] The bonding section 100 has a concave surface. Compared with a planar structure, the concave surface is more conducive to bonding to the teeth, thereby reducing the probability of the bonding section 100 falling off the teeth.

[0034] The traction force transmission section 200 has a first end connected to the bonding section 100, and a second end extending in a direction away from the bonding section 100, and the cross-sectional shape of the first end is an arc. After the bonding section 100 is bonded to the tooth, the traction force transmission section 200 extends in the direction of the gums. Since the first end is an arc, it can adapt to the size of the gums protruding from the tooth surface, reducing the tendency of the second end to extend to the gums to contact the gums, so that the second end avoids direct contact with the gums as much as possible, reducing the pressure on the gums, thereby avoiding ulcers caused by pressure on the gums.

[0035] The hanging and pulling section 300 is connected to the second end of the traction force conducting section 200. The hanging and pulling section 300 has an H-shaped cross section and is staggered with the bonding section 100 in the height direction. Figure 1As shown, the offset setting means that the bonding section 100 and the hanging and traction section 300 are located on opposite sides of the traction force transmission section 200, so they are not in the same height direction. The hanging and traction section 300 is used to hook the traction wire, which can be a chain-shaped rubber band. Since the hanging and traction section 300 is offset from the bonding section in the height direction, most of the hanging and traction section 300 is located on the side away from the gum surface, thereby reducing the probability of the hanging and traction section 300 contacting the gum. The cross-sectional shape of the hanging and traction section 300 is H-shaped, which is conducive to preventing the traction wire from being unhooked, and is also conducive to the traction wire not contacting the gum, thereby avoiding the traction wire from causing pressure on the gum.

[0036] The bonding section of the traction hook provided in the utility model has a concave surface, so that its bonding area is larger and more firm, which reduces temporary re-visits caused by the traction hook falling off during tooth correction and avoids affecting the correction cycle due to the traction hook falling off. The hanging traction section structure adopts an H-shaped design so that during clinical use, the structural plane is parallel to the teeth, reducing the patient's oral foreign body sensation, reducing the wear on the side walls of the oral cavity, and reducing the probability of oral ulcers. The traction force transmission section adopts an arc design so that the middle and lower sections of the traction hook can avoid the protruding gums during use, preventing the gums from being compressed during the correction process and causing oral ulcers.

[0037] In addition, due to the segmented design and different mesh bottom thicknesses, it can be used in conjunction with bracketless invisible orthodontic window designs.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the surface of the bonding section 100 is a curved mesh structure, the width dimension w1 is 4-6mm, for example, the width dimension can be 4mm, 5mm and 6mm, and the height dimension h1 is 3mm. According to clinical experiments, when the width dimension of the bonding section 100 is 5mm, it can better adapt to the shape of the teeth, so as to be firmly bonded to the teeth. The curved mesh structure can further increase the firmness of the bonding between the bonding section 100 and the tooth surface. Since glue is needed to bond the surface of the bonding section 100 to the tooth surface, the curved mesh structure can increase the amount of glue contained between the tooth surface and the bonding section 100 surface, thereby ensuring that the bonding section 100 can be firmly bonded to the teeth.

[0039] like Figure 1 and Figure 2As shown, the shape of the concave surface of the bonding section 100 is circular, the center diameter of the concave surface is 3mm, there are side wings on both sides of the bonding section 100, the width of the side wings is 1-3mm, the end face of the bonding section 100 facing away from the concave surface is arc-shaped, the center thickness of the bonding section is 1mm, and the edge thickness is 0.5mm. The concave surface of the bonding section 100 can be used as the main part bonded to the tooth surface, and the two side wings are used to further increase the contact area between the bonding section 100 and the tooth, so that the bonding section 100 is firmly bonded to the tooth as a whole, thereby preventing the bonding section 100 from falling off the tooth during the subsequent traction process. Due to the segmented design, the mesh bottom thickness is different, and it can be used in combination with the bracketless invisible correction window design.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the side wing surface of the bonding section 100 is a mesh structure, and the side wing surface of the bonding section 100 is also a mesh structure, so that the entire surface of the bonding section 100 is a mesh structure, thereby ensuring that there is a sufficient amount of glue between the surface of the bonding section 100 and the tooth surface, so that the bonding section 100 can be firmly bonded to the tooth.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the edge of one end of the bonding section 100 close to the traction force transmission section 200 is arc-shaped, such as Figure 2 As shown, the side of the bonding section 100 close to the traction force transmission section 200 is an arc convex outward. Since the side of the traction force transmission section 200 is close to the gums, the edge of the bonding section 100 can be prevented from contacting the protruding gums, thereby preventing the gums from being compressed and causing oral ulcers. In addition, the side wall edge of the bonding section 100 can be an arc convex outward, and the outer edge of the side of the bonding section 100 away from the traction force transmission section 200 is an arc concave inward, and the connection between the arc sections is rounded, thereby preventing the edge of the bonding section 100 from having sharp edges and damaging the gums.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the cross-sectional shape of the traction force conduction section 200 is semicircular, and the arc-shaped outer edge of the semicircle is away from the bonding section 100. Such a configuration can ensure that the traction force conduction section 200 can ensure its own strength while making the plane side of the traction force conduction section 200 face the teeth, thereby reducing the radial dimension of the traction force conduction section 200 on the tooth side, thereby further avoiding contact between the traction force conduction section 200 and the teeth or gums, especially avoiding contact with the gums, thereby reducing the pressure on the gums.

[0043] like Figure 1 and Figure 2As shown, in this embodiment, the diameter d1 of the traction force transmission section 200 is 2 mm. Such a configuration can adapt to most spaces in the oral cavity, while also ensuring that the traction force transmission section 200 has sufficient mechanical strength, thereby facilitating the subsequent transmission of traction to the bonding section 100 .

[0044] like Figure 1 and Figure 2 As shown, in the present embodiment, a connecting portion 310 connected to the traction force transmission portion 200 is provided on one side of the hanging traction segment 300, and a hemispherical head 320 is connected to the other side through a column. The hanging traction segment 300 and the connecting portion 310 can be integrally formed to avoid mechanical errors caused by the assembly connection. The spherical side of the hemispherical head 320 is away from the gums, so that even if the buccal mucosa in the oral cavity is in contact with the head 320, it will not cause greater irritation, thereby reducing the foreign body sensation in the oral cavity. The traction wire can be hung on the column, so that the traction wire will not contact the gums or the buccal mucosa, thereby further improving the comfort.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the distance L between the connecting portion 310 and the head 320 is 0.8 mm, and the thickness w2 of the hanging and pulling section 300 is 2.3 mm. Such a design can adapt to the space between the gums and the buccal mucosa to avoid causing a foreign body sensation.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the diameter d2 of the head 320 of the hanging and pulling section 300 is 2 mm, and the thickness g is 0.5 mm. Such a design can adapt to the space between the gums and the buccal mucosa to avoid causing a foreign body sensation.

[0047] In the actual production process, the overall height dimension h2 of the traction hook is 5-11mm, and the height can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm and other specifications. Such a setting can make a reasonable choice according to the patient's actual oral condition, so as to adapt to the patient's oral space and improve the patient's comfort.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
