Description

Technical Field

[0001] The utility model relates to the technical field of bracketless invisible orthodontic treatment, in particular to an invisible orthodontic appliance capable of providing extraoral directional force traction assistance and its structure. Background Art

[0002] During the tooth correction process, extraoral traction is usually used to control the anchorage or achieve the orthopedic effect of controlling the growth and development of children's jaws. However, it is difficult to connect the extraoral traction device or traction elastic band to the surface of the invisible dental appliance.

[0003] Therefore, it is necessary for those skilled in the art to design a device for connecting the extraoral traction invisible dental appliance, which can realize the connection between the structure of the invisible dental appliance itself and the extraoral traction device such as a J-hook, so as to achieve the purpose of directional traction control of the anchorage and control the growth and development of children's jaws. Summary of the Utility Model

[0004] The technical object of the utility model is to provide an extraoral directional force traction structure for bracketless invisible orthodontic treatment in view of the problems in the background art, so as to achieve the orthopedic effect of assisting the invisible dental appliance to move teeth to control the anchorage and control the growth and development of children's jaws.

[0005] In order to achieve the above technical object, the utility model adopts the following technical solutions:

[0006] An extraoral directional force traction structure for bracketless invisible orthodontic treatment, which is configured to be arranged on the invisible dental appliance, preferably on the labial surface of the invisible dental appliance (invisible tooth correction retainer), especially at the tooth adjacent position on the labial surface.

[0007] Specifically, the extraoral directional force traction structure includes a traction component arranged on the surface of the invisible dental appliance. The traction component is configured to cooperate with a traction attachment for orthodontic treatment to achieve directional traction in invisible orthodontic treatment. The directional traction means that the traction attachment is connected to an external auxiliary structure and a certain direction of force is applied to the teeth and jaws through the invisible dental appliance, so as to achieve the orthopedic effect of assisting the invisible dental appliance to move teeth to control the anchorage and control the growth and development of children's jaws.

[0008] The traction component includes a traction part, which is configured to cooperate with the connection part of the traction attachment to realize the connection between the traction component and the traction attachment; the cooperation can be a combination in a physical sense, and this combination can be reversible, that is, detachable, to achieve physical combination when traction is needed and can be detached when adjustment or replacement is needed.

[0009] The traction assembly protrudes from the surface of the invisible dental appliance and is configured to be integrally formed with the invisible dental appliance. The integrally formed structure makes the combination of the traction assembly and the invisible dental retainer more firm, which is beneficial to withstand greater traction force and is more comfortable.

[0010] Preferably, the traction assemblies are arranged in pairs on the left and right. The arrangement in pairs on the left and right includes the arrangement in pairs on the left and right on the upper dental appliance, and / or the arrangement in pairs on the left and right on the lower dental appliance. Specifically, the traction assemblies can be arranged separately on the upper dental appliance or the lower dental appliance, or can be arranged on both the upper dental appliance and the lower dental appliance, which is determined according to the specific situation of orthodontic treatment. Whether arranged separately or both arranged, the traction assemblies are usually in pairs in the left-right direction, and can also be symmetrically arranged left and right according to needs, while there is no need for symmetry or pairing in the up-down direction.

[0011] Preferably, the traction assemblies are configured to be arranged between the adjacent spaces of the corresponding teeth on the invisible dental appliance. Since the traction assemblies protrude from the surface of the invisible dental retainer, and the invisible dental appliance itself will cause discomfort to the wearer. If other attachments are added to its surface, it will surely increase the discomfort of the wearer. And the gap between teeth is concave inward. If the traction assemblies are arranged in this concave area, effectively utilizing the characteristics of the arrangement shape of the teeth themselves, it can obviously relieve the additional discomfort brought by such added attachments.

[0012] Preferably, the traction assemblies adopt an arch structure, and their positions on the invisible dental retainer are configured to span the adjacent spaces located in the front and middle segments of the dental arch. Preferably, the radian of the arch is generally between 1.5 and 3.5 rad.

[0013] Preferably, considering the different teeth and gap sizes of different patients, the overall span of the traction assemblies is between 1.5 and 5.0 mm, preferably 2.5 to 5 mm; the overall width of the traction assemblies is between 1.0 and 3.0 mm, preferably 1.5 mm; the overall thickness (height) of the traction assemblies is between 1.5 and 5.5 mm, preferably 2 to 4 mm.

[0014] Preferably, the traction part includes a through structure provided on the traction assembly. This through structure can be completed during the production of the invisible dental appliance, or only the traction assembly can be provided and completed by the user with a dental bur in the clinic.

[0015] Preferably, the through structure includes a through hole. The through hole is close to the surface of the invisible dental retainer and penetrates the traction assembly as a whole from the tooth surface to the root direction. The aperture of the through hole is between 0.5 and 1.8 mm, preferably 0.7 to 1.5 mm.

[0016] Preferably, the traction attachment includes an extraoral traction device and / or traction elastics. The traction attachment is configured to provide a traction force for orthodontic treatment, and the direction of the traction force is configured to be adjustable according to the actual treatment or the actual situation of the patient.

[0017] The beneficial effects of the present utility model are as follows:

[0018] (1) By providing a traction assembly on the invisible braces, the present utility model can be connected to an extraoral traction structure, realizing the connection between the structure of the invisible braces itself and an extraoral traction device such as a headgear J-hook, which is beneficial to assisting in forming a directionally adjustable traction force, achieving the orthopedic effect of assisting the invisible braces in moving teeth, controlling anchorage, and controlling the growth and development of children's jaws.

[0019] (2) The traction assembly of the present utility model is used as a force application point and is manufactured by an integral molding method with the invisible teeth retainer, which improves the firmness, increases the stress intensity, and is beneficial to the establishment of a directional force correction system.

[0020] (3) The traction assembly of the present utility model is arranged in the interdental space, making clever use of the position space generated by the shape and arrangement rules of the teeth themselves, which can effectively reduce the discomfort brought to the wearer by the orthodontic attachments.

[0029] The following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings. It should be noted that the embodiments are only specific elaborations of the utility model and should not be regarded as limitations of the utility model. The purpose of the embodiments is to enable those skilled in the art to better understand and reproduce the technical solutions of the present utility model. The protection scope of the present utility model should still be subject to the scope defined by the claims.

[0030] To enable those skilled in the art to better understand the technical solutions of the present utility model, some technical terms of the present utility model will be explained first. In the text of the present utility model, these explanations are mainly to help those skilled in the art understand and implement the technical solutions of the present utility model, rather than limitations of the present utility model. And when there may be other technical understandings of these technical terms in other disclosures outside the present utility model, to avoid technical ambiguities, when understanding the present utility model, it should be based on the explanations of the present utility model.

[0031] An invisible dental appliance, also known as a bracketless invisible orthodontic appliance, is a device for treating malocclusion. It can generate acting forces to cause changes in the deformed jawbones, misaligned teeth, and periodontal supporting tissues, so as to facilitate the normal growth and development of the dentofacial region. Traditional orthodontic appliances are usually mechanical devices composed of an elastic metal wire and brackets, or combined with a plastic base, and are worn in the oral cavity or maxillofacial region. Since orthodontics is a long-term process and patients need to wear orthodontic appliances for a long time, the orthodontic appliances not only bring great inconvenience to the patients' lives but also have a great impact on the patients' appearance. Therefore, more and more orthodontic patients choose bracketless invisible dental appliances.

[0032] The bracketless invisible dental appliance, commonly known as an invisible dental appliance, is made of a transparent material and customized according to the shape of the patient's teeth and gums. After being worn, the invisible dental appliance covers the tooth surface. Due to the transparency of the material and its conformity with the tooth shape, compared with traditional orthodontic appliances, it is not only aesthetically pleasing but also can reduce the discomfort of the wearer.

[0033] Early orthodontics refers to the prevention of the causes that may lead to malocclusion during the growth and development stage of children, especially around the peak of growth and development, and the blocking and correction of the existing malocclusion, so as to create a more favorable growth environment for the future development of the dentofacial region. Adjusting the growth and development of the jawbones is more effective when implemented in the early stage. Therefore, more consideration needs to be given to the control of the growth and development of the maxillofacial bones in early orthodontics. The extraoral directional force traction structure provided by the present utility model is very targeted at this situation in early orthodontics.

[0034] The mesial and distal of a tooth, where "middle" refers to the midline, and the midline is an imaginary vertical line that divides the cranial face into two equal parts. When a person puts his face in front of a mirror, a line is drawn between the midpoint of the hairline and the midpoint of the line between the eyebrows. This line is called the midline of the face. Mesial refers to the direction in which the tooth is closer to the midline of the face, and distal refers to the direction farther away. In the present invention, the mesial and distal of a tooth can be used to refer to the two surfaces on both sides of the gap between two adjacent teeth. The mesial surface of the same tooth that is closer to the midline is the mesial surface, and the distal surface that is farther away from the midline is the distal surface.

[0035] like Figure 1 As shown, this embodiment provides a directional force traction structure for invisible braces, including a traction component 2 arranged on the surface of an invisible brace 1. In order to achieve directional force correction, the traction component 2 of this embodiment is preferably arranged on the labial surface 101 of the invisible brace 1, as shown in FIG. Figure 1 shown.

[0036] like Figure 2 As shown, the traction component 2 protrudes from the surface of the invisible braces 1, and is configured to be integrally formed with the invisible dental braces retainer. The integrally formed structure makes the combination of the traction component 2 and the invisible braces 1 more secure, which is conducive to bearing greater traction force.

[0037] In order to facilitate the systematic adjustment of the jaw and ensure that the force can be adjusted according to the actual situation, the traction components are arranged in pairs on the left and right sides, and the left and right paired arrangement includes left and right paired arrangement on the upper braces and / or left and right paired arrangement on the lower braces. It can also be arranged symmetrically on the left and right sides. In this embodiment, if Figure 1 As shown, taking the upper braces as an example, the traction assembly 2 is symmetrically arranged on the labial surface of the upper braces.

[0038] Preferably, the traction component 2 is configured to be arranged between the interproximal spaces of the corresponding teeth on the invisible braces. Since the traction component protrudes from the surface of the invisible braces, and the invisible braces themselves will cause discomfort to the wearer, if other accessories are added to the surface, the discomfort of the wearer will inevitably be aggravated, and the gaps between teeth are recessed inwards. If the traction component is arranged in this recessed area, the characteristics of the arrangement shape of the teeth themselves are effectively utilized, and the additional discomfort caused by the added accessories can obviously be alleviated.

[0039] The traction assembly adopts an arched structure, which is configured to span the middle of the interproximal teeth located in the front and middle sections of the dental arch at the position of the invisible dental orthodontic retainer. Preferably, the curvature of the arch is generally between 1.5 and 3.5 rad. Figure 2 and 4As shown, in this embodiment, taking the following dental appliance as an example, the traction assembly 2 is generally arched. The two ends of this arch are respectively arranged on the mesial surfaces and distal surfaces of two adjacent teeth of the lower dental appliance (the mesial tooth has a distal surface, and the distal tooth has a mesial surface), and span the gap between the two teeth. Figure 2 The longer single dashed line in the figure indicates the position of the gap between the two teeth, and the shorter double dashed line indicates the position of the through hole. Since an arched structure is adopted and the traction assembly in a prominent shape is arranged at the gap between the two teeth, the position and arrangement space of the teeth themselves are utilized to minimize the discomfort brought to the wearer by the attachments.

[0040] In addition, the size design of the traction assembly needs to consider the different teeth and gap sizes of different patients. Therefore, generally speaking, as Figure 3-4 shown, the overall span L of the traction assembly of the present utility model is between 1.5 and 5.0 millimeters, preferably between 2.5 and 5 millimeters; the overall width W of the traction assembly is between 1.0 and 3.0 millimeters, preferably 1.5 millimeters; the overall height H of the traction assembly is between 1.5 and 5.5 millimeters, preferably between 2 and 4 millimeters.

[0041] The traction assembly 2 includes a traction part 3. In this embodiment, as Figure 2 and 4 shown, the traction part includes a through structure arranged on the traction assembly 2. The through structure includes a through hole, which can be reserved during integral molding or drilled after integral molding. The aperture of the through hole is between 0.5 and 1.8 millimeters, preferably between 0.7 and 1.5 millimeters.

[0042] In a specific embodiment, as Figure 5 shown, the traction part 3 is configured to cooperate with the connection part of the traction attachment 4 (such as the hook part of the headgear J-hook) to realize the connection between the traction assembly and the traction attachment. Figure 5 Shows the process of connecting the headgear J-hook and the traction assembly 2 in this embodiment.

[0043] In a specific embodiment, as Figure 6 shown, in actual operation, usually the invisible dental appliance 1 is put on first, and then the traction attachment 4 (J-hook) is installed. After installation, it is connected to the headgear through the rubber band 5 to generate a directional force for traction. The number of J-hooks can be selected according to actual needs; when wearing, in order to relieve the discomfort caused by the J-hook to the patient's face, a protective pad 6 can be added between the J-hook and the facial skin, and the J-hook can pass through the protective pad.

[0044] In a specific embodiment, as Figure 7As shown, multiple connection holes 8 for traction forces in different directions can be provided on the headgear (or with the adjustment accessory 7). The directions indicated by the dashed arrows in the figure are the directional force directions corresponding to different connection holes. The adjustment accessory can be connected to different connection holes 8 according to actual needs to adjust the directional force direction. Alternatively, the J-hook can be twisted to change its own direction to achieve the above-mentioned adjustment of the directional force direction.

[0045] After the headgear J-hook is connected, it forms a directional force orthodontic system as shown in Figure 6 and 7 By connecting the J-hook and the invisible braces, a force in a certain direction is applied to the teeth and jaws, with the aim of achieving the orthopedic effect of assisting the invisible braces to move the teeth, controlling the anchorage, and controlling the growth and development of children's jaws.

[0046] Since invisible orthodontics requires continuous regular reviews and replacement of braces, and the growth and development of the jaws also need to be continuously checked during early orthodontics, according to the patient's condition, when making new invisible braces, the traction structure of the present utility model can be set at an appropriate position, the direction of the directional force can be adjusted, and the growth and development of the maxillofacial region can be controlled to achieve a better orthodontic effect.

[0047] Although the preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0048] It should be noted that the technical features not described in detail in the present utility model can all be realized by any existing technology.
