Description

Technical Field

[0001] This utility model belongs to the field of orthodontic medical device technology, and in particular relates to an invisible orthodontic appliance with a palatal arch expansion device. Background Technology

[0002] Arch expansion is a common method in invisible orthodontic treatment for correcting malocclusion caused by narrow dental arches. Therefore, in orthodontic treatment, shell-shaped dental instruments capable of opening the maxillary dental arch are required. Currently, in clinical application, shell-shaped dental instruments with palatal arch expansion devices typically have a palatal arch expansion device that is integrally molded with the shell body, forming a structure with reinforcing ribs that fits snugly against the maxillary palate. Its structure is as follows: Figure 1 As shown, conventional clear aligners, because they lack a membrane support on the palate, transmit less force to the teeth, resulting in lower orthodontic efficiency and effectiveness. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides an invisible orthodontic appliance with a reinforced rib structure that extends the orthodontic diaphragm to the entire palate and is integrally pressed into a shell-like body to fit the maxillary palate, thereby enhancing the arch expansion force of the invisible orthodontic appliance and increasing the orthodontic effect.

[0004] To achieve the above objectives, this utility model provides an invisible orthodontic appliance with a palatal expansion device, including an appliance body, the appliance body having several cavities for accommodating teeth, and a palatal expansion device, the palatal expansion device being disposed between the canines and the lingual gingival margin of the posterior teeth on both sides of the appliance body, the palatal expansion device being integrally formed with the appliance body and conforming to the maxillary palate, the palatal expansion device completely covering the entire palate.

[0005] Furthermore, the palatal arch expander is provided with a reinforcing rib, which is integrally formed with the palatal arch expander and protrudes toward the opposing dentition.

[0006] Furthermore, the reinforcing rib is cylindrical, and the portion of the reinforcing rib protruding from the gum is semi-circular, with the shape of the reinforcing rib following the concave and convex shape of the palate.

[0007] Furthermore, the cylindrical diameter of the reinforcing rib is 2 mm.

[0008] Furthermore, multiple reinforcing ribs are provided, and the spacing between adjacent reinforcing ribs is 3 mm to 5 mm.

[0009] Furthermore, the reinforcing rib is positioned near the posterior tooth area.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention's invisible aligner with a palatal expansion device can comprehensively conform to and wrap around the palate, providing a fully enclosed fit that follows the natural gingival contour of each patient's jaw. Furthermore, the reinforcing ribs are integrally molded with the entire palatal structure. This design effectively increases palatal support strength, enhances palatal mucosal coverage, increases the aligner's surface area, and strengthens the force application, thus significantly improving treatment efficiency. Attached Figure Description

[0012] The specific embodiments of this utility model will be further explained below with reference to the accompanying drawings.

[0013] Figure 1 This is a schematic diagram of a shell-shaped dental instrument with a palatal arch expander in the prior art.

[0014] Figure 2 This is a schematic diagram of the invisible orthodontic appliance with a palatal arch expander according to the present invention.

[0015] In the diagram: 10 - the orthodontic appliance; 20 - palatal arch expander; 21 - reinforcing rib. Detailed Implementation

[0016] Combination Figure 2 The invisible aligner with palatal expansion device in this embodiment includes an aligner body 10, which has several cavities for accommodating teeth, and also includes a palatal expansion device 20. The palatal expansion device 20 is disposed between the lingual gingival margins of the canines to the posterior teeth on both sides of the aligner body 10. The palatal expansion device 20 is integrally formed with the aligner body 10 and fits the maxillary palate. The palatal expansion device 20 completely covers the entire palate.

[0017] In a preferred embodiment, the palatal arch expander 20 is provided with a reinforcing rib 21, which is integrally formed with the palatal arch expander 20 and protrudes toward the opposing dentition.

[0018] In this preferred embodiment, the reinforcing rib 21 is cylindrical, and the part of the reinforcing rib 21 that protrudes from the gum is semi-circular. The shape of the reinforcing rib 21 follows the concave and convex shape of the palate.

[0019] In this preferred embodiment, the cylindrical diameter of the reinforcing rib 21 is 2 mm.

[0020] In this preferred embodiment, multiple reinforcing ribs 21 are provided, and the spacing between adjacent reinforcing ribs 21 is 3mm to 5mm.

[0021] In this preferred embodiment, the reinforcing rib 21 is positioned near the posterior tooth area.

[0022] In this embodiment, specifically, the posterior tooth region refers to teeth 4, 5, and 6, and the number and spacing of the reinforcing ribs 21 are set according to the actual palatal morphology of the case. For example... Figure 2 As shown, the orthodontic appliance in this embodiment has three reinforcing ribs 21, with a spacing of 5 mm between each rib. A standard tooth morphology is defined. If the overall spacing of the first to sixth / seventh teeth in the palate of the patient is greater than the standard tooth morphology, the spacing between adjacent reinforcing ribs 21 is set to 5 mm; if the overall spacing of the first to sixth / seventh teeth in the palate of the patient is less than the standard tooth morphology, the spacing between adjacent reinforcing ribs 21 is adjusted according to the spacing ratio. In this invention, the standard tooth morphology defines the standard tooth spacing as 35 mm, which refers to the distance from the maxillary central incisor to the distal end of the maxillary first molar.

[0023] This embodiment of the invisible aligner with a palatal arch expander features a design that fully covers the palate, and the palatal arch expander is integrally molded with the aligner body. It also includes an integrally molded reinforcing rib, making the force applied by the aligner more effective. Compared to existing aligners that only cover a small portion of the palatal mucosa, it has significant technical advantages in overall structural strength and clinical application results. In practical applications, depending on the doctor's design requirements, it is necessary to open up the relative width of the posterior teeth area and the width of the dental arch, and combine this with other orthodontic solutions (increasing movable space, reconstructing the occlusal state) to achieve correction.
