The drawings are schematic diagrams or conceptual diagrams, and the relationship between the thickness and the width of each part, the proportional relationship between the parts and the like are not completely consistent with actual values.

Example one

Fig. 1 and fig. 2 show a schematic structural diagram of a dental appliance according to an embodiment of the present invention, which includes amouthpiece body 100 capable of being worn on a maxillary dentition, the structure of themouthpiece body 100 is substantially similar to that of an existing invisible mouthpiece for orthodontics, and each has an inner profile adapted to match with the position adjustment of teeth of the dentition, and is adapted to be worn on the maxillary dentition.

Fig. 1 shows an example where themouthpiece body 100 is worn at theteeth 10, 20, and 30, and there is a space between theteeth 10 and 20, and theteeth 20 need to be straightened with the goal of advancing theteeth 20 to be close to theteeth 10. While theattachment 600 is fixedly attached to thetooth 20, in the present embodiment, theattachment 600 is disposed on the labial and buccal sides of thetooth 20, and thetooth 20 can be moved in a direction approaching thetooth 10 by applying a lateral force (a leftward force in a view of fig. 1) to theattachment 600.

Themouthpiece body 100 is provided with a strip-shaped throughhole 110, thethrough hole 110 extends transversely in length, the width of thethrough hole 110 is suitable for accommodating theaccessory 600, and preferably, the vertical dimension of theaccessory 600 is not greater than the width of thethrough hole 110. The throughhole 110 is located corresponding to thetooth 20, and specifically, when themouthpiece body 100 is worn, theattachment 600 enters the throughhole 110, while theright side surface 111 of the throughhole 110 abuts against theattachment 600, or the right side of theattachment 600 abuts against theright side surface 111 of the throughhole 110, and theright side surface 111 of the throughhole 110 generates a pushing force to theattachment 600, specifically, a pushing force that pushes theattachment 600 leftward.

The source of the above-mentioned pushing force may be based on the elastic restoring force of themouthpiece body 100, if there is a certain distance difference between the position of the throughhole 110 on themouthpiece body 100 and the position of theattachment 600, specifically, theright side 111 of the throughhole 110 is closer to thetooth 10 than the right side of theattachment 600, so that when themouthpiece body 100 is worn, due to the offset between the positions of thethrough hole 110 and theattachment 600, when theattachment 600 is disposed in the throughhole 110, theattachment 600 abuts against theright side 111 of the throughhole 110, so that the throughhole 110 is laterally stretched to the right, and the material of themouthpiece body 100 at theright side 111 and the connection part near theright side 111 is deformed to generate a resilient force, thereby generating a leftward pushing force to theattachment 600, that is, the elastic restoring force for restoring the throughhole 110 to the original state (non-deformed state).

When themouthpiece body 100 is worn, a moving space for theteeth 20 to move towards theteeth 10 is formed between theteeth 10 and theteeth 20, at this time, themouthpiece body 100 completely or partially covers the buccal surface, the palatoglossal surface and the occlusal surface of theteeth 20, but does not cover or block the left side of theteeth 20, and meanwhile, a space is reserved for a path of a position high point in the process that theteeth 20 move to the target position, compared with the case that the existing attachment is wholly wrapped by the mouthpiece, in the orthodontic process of the orthodontic device of the embodiment, theteeth 20 are not blocked in the orthodontic moving direction, and can move for a longer distance. The overall retention of themouthpiece body 100 may depend on other attachments disposed on the teeth, and will not be described herein.

In other embodiments, theshell body 100 does not completely encase theteeth 10, 30, only partially covers the crown surfaces of the teeth or only contacts other attachments to the surfaces of theteeth 10, 30, and the remainder of the crown may be used for adhesion of other appliances.

In this embodiment, themouthpiece body 100 is integrally formed, or themouthpiece body 100 may be obtained by cutting and adjusting the integrally formed model. Preferably, the printing can be performed by 3D printing.

For a shell structure integrally wrapping a tooth like theshell body 100 in fig. 1, the throughholes 110 may affect the elastic stress of the surrounding shell portion and the strength of maintaining the shape thereof, so that the local elastic stress is released at the throughholes 110, thereby affecting the correction of the surrounding teeth, for example, when thetooth 10 and/or thetooth 30 needs to be corrected by the elastic restoring force of theshell body 100, the throughholes 110 may weaken the elastic stress, thereby affecting the correction effect on thetooth 10 and/or thetooth 30.

Therefore, as shown in fig. 3, asidewall area 120 is defined around the throughhole 110 on themouthpiece body 100, and it can be understood that theannular sidewall area 120 defines the throughhole 110, and the size of thesidewall area 120 can be controlled to be adjusted in the corresponding area of thetooth 20. It should be noted that thesidewall area 120 is shown for the purpose of defining a certain area on themouthpiece body 100 for specific description, and does not mean that thesidewall area 120 is necessarily separated from themouthpiece body 100, and thesidewall area 120 may be a part of the integral structure of themouthpiece body 100. As shown in fig. 4, the thickness of thesidewall area 120 is greater than that of the adjacent area, and generally speaking, the thickness difference of the entire mouthpiece is smaller, and after the thickness of thesidewall area 120 is increased, thesidewall area 120 is more difficult to deform relative to the adjacent area, so as to limit the release of elastic stress at the throughhole 110 caused by the opening of the throughhole 110, and simultaneously ensure that the moving path does not deviate from thepredetermined track 110 during the moving process of thetooth 20 driven by theattachment 600.

In other embodiments, the thickness of thesidewall region 120 is not adjusted, but the hardness of thesidewall region 120 is adjusted, so that the hardness of thesidewall region 120 is greater than that of the adjacent region, and thesidewall region 120 is less likely to deform relative to the adjacent region; or the hardness of thesidewall area 120 is less than that of the adjacent area, so that the elastic stress is released more softly and slowly. I.e., the elastic stress relief at the via 110 is limited by the difference in stiffness of thesidewall region 120 and its adjacent regions.

In other embodiments, the thickness and hardness of thesidewall region 120 are adjusted simultaneously, such that the thickness of thesidewall region 120 is greater than the thickness of the adjacent region, and the hardness of thesidewall region 120 is different from the hardness and elasticity of the adjacent region, so as to better limit the elastic stress relief at the throughhole 110.

In other embodiments, thesidewall region 120 is configured as a separate component from themouthpiece body 100 and is fixedly attached to themouthpiece body 100, such as by gluing, snap-fit connection, etc., where the through-hole 110 is defined by the ring-shaped component, i.e., the through-hole 110 is the central through-hole of the ring-shaped component. In some embodiments, the component is made of a metal material, such as a metal material that is rolled into a square tube shape, so that the component can be made thinner.

On the other hand, during the whole treatment process whenmouthpiece body 100 is worn,attachment 600 will always contactupper side 112 and/orlower side 113, and the amount of friction when they contact will also affect the amount of movement ofteeth 20, so that the friction generated during the relative movement ofattachment 600 and it can be reduced by changing the elasticity and hardness of the edges of the above components.

In order to improve the friction between theattachment 600 and theupper side 112 and/or thelower side 113, in other embodiments, the side of the throughhole 110 is configured as a curved surface, specifically, as an outer curved surface, i.e., the curved surface is convex outward, or is curved inward of the throughhole 110, as shown in fig. 5. In fig. 5, by providing theupper side 112 and thelower side 113 with outer curved surfaces, the contact between theattachment 600 and theupper side 112 and/or thelower side 113 is changed from surface contact to line contact, so as to reduce the friction between the two, which is beneficial to increase the moving amount of theteeth 20. In addition, the curved surface can be provided as a curled structure, which not only increases the thickness and strength of the side of the throughhole 110, but also enables the curved surface structure contacting with theaccessory 600 to provide better elasticity than a plane contact, for example, theteeth 20 are horizontally pushed to generate a vertical offset, i.e. theaccessory 600 can vertically offset and press theupper side 112 or thelower side 113, although theupper side 112 or thelower side 113 of the plane structure can also provide elastic force to theaccessory 600 to keep the accessory 600 at the expected vertical position, but theupper side 112 or thelower side 113 adopts the curved surface structure to be more elastic than the plane structure, so that the elastic force applied to theaccessory 600 is more favorable for keeping theaccessory 600 at the expected vertical position.

The curved configuration described above with respect to theupper side 112 and thelower side 113 in fig. 5 may also be used for theright side 111, which helps to provide a slow release of the pushing force on theattachment 600, making the force more gentle and durable. Preferably, theright side 111 is provided with a crimping structure, as described above, to further enhance the optimization of the pushing force.

In other embodiments, another way is to provide the curved surface of theright side 111, as shown in fig. 6, theright side 111 is provided with a curved surface comprising a wave-shaped convex, so that the pushing force can be released slowly and is more gentle and durable when the pushing force is applied to theaccessory 600. The shape and number of undulations in the above-described structure are not limited herein.

In other embodiments, as shown in fig. 7, themouthpiece body 100 is provided with a mounting groove 130 (shown by dotted lines) at a region located at the right side of theattachment 600, and both ends of theelastic sheet 140 engaged with the mountinggroove 130 can be inserted and restrained in the mountinggroove 130, so that theelastic sheet 140 bends toward theattachment 600 and provides a force thereto against theattachment 600. While the above-mentioned technical effect of curving theright side surface 111 can be obtained, the pushing force can be adjusted by selecting differentelastic pieces 140, for example, the pushing force applied to theaccessory 600 can be adjusted by selecting differentelastic pieces 140 with different materials and/or sizes, and the material of theelastic pieces 140 can be metal, plastic, etc., which is not limited herein.

Fig. 8 shows an example in which the throughhole 110 of themouthpiece body 100 extends in a vertical direction, and theteeth 10, 20 and 30 are required to pull theteeth 20 downward, and when themouthpiece body 100 is worn, theattachment 600 abuts against an upper side of the throughhole 110, so that theteeth 20 are moved downward by the pushing force of the side. In practical use, the extending direction of the throughhole 110, the shape and the cross section of the track can be correspondingly set according to the orthodontic requirement.

Example two

Fig. 9 and 10 are schematic structural views illustrating a dental appliance according to another embodiment of the present invention, which includes amouthpiece body 200 that can be worn on the maxillary dentition. In the case ofteeth 10, 20 and 30, andattachment 600, the same arrangement is used as in the first embodiment.

In this embodiment, the inner side of themouthpiece body 200 is provided with a strip-shapedgroove 210, when themouthpiece body 200 is worn, theaccessory 600 enters thegroove 210, and meanwhile, theaccessory 600 abuts against theside wall 211 of thegroove 210, and the side generates a pushing force on theaccessory 600, specifically, a pushing force for pushing theaccessory 600 to the left.

Preferably, the width and depth of thegroove 210 are moderately enlarged relative to the size of theaccessory 600, so that theside walls 212, 213 and thebottom surface 214 of thegroove 210 can keep a certain distance from theaccessory 600, i.e. a gap can be reserved between thegroove 210 and theaccessory 600.

The channel defined by thegroove 210 in the first embodiment is similar in structure to the throughhole 110 in the first embodiment, and can achieve the same function as the throughhole 110. The present embodiment is also understood to be based on the structure of the first embodiment, wherein the exposedattachment 600 is wrapped in the mouthpiece body.

The throughhole 311 in the present embodiment is substantially identical to the throughhole 110 in the first embodiment in structural arrangement, and can achieve the same function as the throughhole 110. Accordingly, embodiments related to themouthpiece body 100 and the throughhole 110 can be used for themouthpiece body 300 and the throughhole 311, including the configuration related to the thrust generation, the configuration of the side shape or structure of the throughhole 110, the configuration of the extending direction of the throughhole 110, and so on, which are not described herein again. Furthermore, the definition of the sidewall region for the throughhole 311 may preferably be extended to thewhole strip member 310, i.e. the provision of thesidewall region 120 in the first embodiment is applied to thestrip member 310, which is advantageous for enhancing the retention and correction effect of the mouthpiece.

In other embodiments, throughhole 311 is replaced by a groove structure as in embodiment two, so thataccessory 600 is not exposed, but rather is wrapped by the mouthpiece body.
