Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tooth correction, and specifically relates to a partial position hollow appliance. BACKGROUND

[0002] At present, in the field of tooth orthodontics, under the scene of premature loss of deciduous teeth, adjacent teeth may tilt or move to occupy the space required for the eruption of permanent teeth; or the permanent teeth do not fully erupt, and other teeth need orthodontic treatment, which may affect the eruption path of the permanent teeth that do not fully build the jaw or hinder the development when a traditional mouthpiece is used. In view of this, the technical personnel in the field currently usually use a gap maintainer, which helps the permanent teeth to erupt in the correct position and avoid malocclusion.

[0003] There are many types of current maintainers, such as a wire ring type maintainer, a lingual arch type gap maintainer, and a palatal arch type gap maintainer, but the above maintainers all have the following defects. Since the maintainers are fixedly arranged at the eruption position, and the maintainers are metal structures, they can easily cause discomfort to the patient, and the maintainers used cannot be used in cooperation with a clear mouthpiece, so the teeth cannot be arranged gradually.

[0004] In addition, the current design of an eruption cap on a clear mouthpiece is used to maintain a gap and reserve space for the eruption of permanent teeth when the teeth are arranged, but due to the limitation of the size of the eruption cap and the low accuracy of the prediction of the eruption path, the eruption teeth may be compressed or inhibited from growing in clinical practice.

[0005] In view of this, the technical personnel in the field need to improve the existing clear mouthpiece to overcome the above defects, while having the functions of gap maintenance and occlusal induction when the teeth are arranged, and being more comfortable and safe, which is conducive to the natural growth and development of the teeth of the patient. CONTENT OF THE UTILITY MODEL

[0006] The main purpose of the present application is to provide a partial position hollow appliance, which adopts a hollow design on a clear mouthpiece, and additionally has a support for occlusal induction, which not only maintains a gap for the eruption teeth, but also provides support when the teeth are arranged to provide a high arrangement effect.

[0007] In order to achieve the above purpose, in the first aspect, the present application provides a partial position hollow appliance, which comprises a correction mouthpiece body and a hollow part corresponding to at least one tooth, and the palatal side or the lingual side of the hollow part has a support, and the two ends of the support are fixedly connected with the correction mouthpiece body.

[0008] Optionally, the support is rod-shaped, sheet-shaped or strip-shaped.

[0009] Optionally, the thickness of the support is greater than the thickness of the correction mouthpiece body.

[0010] Optionally, the thickness of the support is 0.4mm-50.0mm, and the thickness of the orthodontic aligner is 0.4mm-0.8mm.

[0011] Optionally, the orthodontic aligner body is integrally formed.

[0012] Optionally, the support and the orthodontic aligner body are integrally formed.

[0013] Optionally, the support and the orthodontic aligner body are formed by 3D printing.

[0014] Optionally, the support is fixedly provided with a plurality of reinforcing support pieces.

[0015] Optionally, the width of the reinforcing support piece is greater than the width of the support.

[0016] Optionally, the inner side of the support has a plurality of guide inclined surfaces or arc surfaces.

[0017] The partial position hollow aligner has the advantages that the hollow structure is arranged on the invisible aligner, and the auxiliary support is arranged for bite induction, the support has a self-defined thickness, provides tooth arrangement for erupted teeth, and can define the position, which not only maintains the gap of the erupted teeth, but also can simultaneously arrange the teeth, is simple in structure, and is convenient to use.

For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific circumstances.

[0029] In addition, the meaning of the term "a plurality of" should be two and more than two.

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] Embodiment one:

[0032] As Figure 1As shown in the drawings, a partial position hollowed appliance includes a treatment mouthpiece body 1 and at least a hollow part 2 corresponding to a tooth, and the hollow part 2 has a support 3 on at least one side, and the two ends of the support 3 are fixedly connected with the treatment mouthpiece body 1.

[0033] Generally, the two sides of the mouthpiece are divided into the palatal / lingual side and the buccal / labial side, and the palatal / lingual side or the buccal / labial side of the hollow part 2 is provided with the support 3, and preferably, the palatal / lingual side is provided with the support 3.

[0034] Embodiment two:

[0035] As shown in the drawings, Figure 2 , Figure 4 , Figure 5 The difference between the embodiment one and the embodiment two is that the two sides of the hollow part 2 are provided with the support 3.

[0036] In the above structure, the treatment mouthpiece body 1 is used for arranging teeth of erupted teeth, the hollow part 2 corresponds to the position of the erupted teeth, and the support 3 is used for maintaining the gap and supporting the arrangement of the teeth, thereby avoiding the use of traditional metal retainers and the design of erupted caps, and realizing occlusion induction.

[0037] In the embodiment, the support 3 is in the shape of a rod, a sheet or a strip, and preferably in the shape of a rod, and the thickness of the support 3 is greater than or equal to the thickness of the treatment mouthpiece body 1, so that the support 3 can provide strong support during the arrangement of the teeth while maintaining the gap, and thus it not only realizes the gap maintenance for the erupted teeth, but also provides better support for the already erupted teeth during the arrangement of the teeth. The thickness of the conventional treatment mouthpiece is 0.4mm-0.8mm, and it should be noted that the specific value needs to be selected according to the specific situation.

[0038] In order to facilitate processing, the treatment mouthpiece body 1 is integrally formed, the support 3 is integrally formed with the treatment mouthpiece body 1, and further, the support 3 and the treatment mouthpiece body 1 are formed by 3D printing. The material of 3D printing can be selected as polyurethane acrylate material.

[0039] Since the hollow part 2 corresponds to at least one tooth, i.e. there is at least one erupted tooth at this position, when there are multiple teeth, the erupted teeth need to be guided to grow, therefore, the inner side of the support 3 has a plurality of guide inclined surfaces or arc surfaces, and then the erupted teeth grow in an orderly manner under the guidance of the guide inclined surfaces or arc surfaces during the growth process.

[0040] Embodiment three:

[0041] As shown in the drawings, Figure 3The difference between the embodiment and the embodiment one is that the support 3 is fixedly provided with a plurality of reinforcing support pieces 4, and preferably, the width of the reinforcing support piece 4 is greater than the width of the support 3.

[0042] By arranging the reinforcing support piece 4, the adjacent teeth which have erupted can be forced at the same time when the physiological eruption of the erupted teeth is considered, so that the correction effect is improved.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
