Description

Technical Field

[0001] This utility model relates to the field of dental medical devices, and in particular to a head cap invisible muscle stimulator. Background Technology

[0002] Adolescent patients with skeletal Class II high-angle malocclusion exhibit mandibular underdevelopment, characterized by mandibular retrusion, increased ANB angle, and distal molar relationship. In addition to sagittal abnormalities, they also experience vertical abnormalities and growth abnormalities. Class II skeletal malocclusion results from uncoordinated development of the maxilla and mandible. This is caused by severe mandibular underdevelopment and weak vertical condylar growth, while the vertical growth of the posterior alveolar bone in both the maxilla and mandible, along with strong anterior growth of the maxilla, collectively leads to downward and posterior rotation (clockwise) of the mandible. This downward and posterior rotation further exacerbates the vertical abnormalities.

[0003] Cephaloperidol appliances are typically used to control the vertical height of the maxillary anterior and posterior teeth and the protrusion of the maxillary anterior teeth, while also guiding the mandible and inducing mandibular development. However, patients with skeletal Class II high-angle malocclusion are further divided into deep overbite and open bite. If deep overbite exists, after guiding the mandible, the overlap of the upper and lower anterior teeth decreases, and a gap appears between the upper and lower posterior teeth. After removing the cephaloperidol appliance, the lower posterior teeth will elongate until all posterior teeth make contact to stabilize the occlusion. Because the elongation of the lower posterior teeth will cause the mandible to rotate posterolaterally, it will aggravate the vertical abnormality. Later, it will be necessary to use bone screws or other means to further depress the lower posterior teeth, increasing the difficulty of later orthodontic treatment. However, for patients with high-angle mandibular retrusion accompanied by deep overbite, the treatment goal is to achieve anterior superior rotation (counterclockwise rotation) of the mandible to reduce the height of the lower third of the face. Therefore, current cap muscle activators are not suitable for treating patients with skeletal Class II high-angle mandibular retrusion and deep overbite of the lower anterior teeth. Summary of the Invention

[0004] Based on this, it is necessary to provide a head-cap invisible muscle stimulator to address the above-mentioned technical problems. This device controls the vertical height of the maxillary anterior and posterior teeth, controls the protrusion of the maxillary anterior teeth, guides the mandible forward, and simultaneously depresses the mandibular anterior teeth to prevent the elongation of the mandibular posterior teeth. This controls the occlusal plane, reduces the posterior-inferior rotation of the mandible, and achieves the anterior-superior rotation (counterclockwise rotation) of the mandible.

[0005] This utility model provides a headgear-mounted invisible muscle stimulator, comprising: The maxillary base includes a base and an extraoral arch, wherein the base has an occlusal pad on the occlusal surface of the posterior teeth region, and the occlusal pad has an upper guide slope. The mandibular invisible part consists of a shell-shaped invisible aligner, with a mandibular pad on the occlusal surface of its posterior or anterior teeth region, and the mandibular pad is provided with a lower guide bevel. The upper occlusal pad is located behind the lower occlusal pad, and the upper guide slope coincides with the lower guide slope during occlusion, which helps to guide the mandibular incisor ends to align with the maxillary incisor ends; the multiple shell-shaped clear aligners of the mandibular invisible part have inconsistent positions and heights of the lower anterior teeth, and cover the crown of the mandibular teeth.

[0006] In one embodiment, the base of the maxillary base includes a body, an occlusal pad, and an incisor cap, the body connecting the occlusal pad and the incisor cap, the occlusal pad covering the maxillary posterior teeth, and the incisor cap covering the incisal edge and labial surface of the maxillary anterior teeth.

[0007] In one embodiment, the incisor cap is provided with a bi-curved labial arch to limit the labial tilt of the upper anterior teeth.

[0008] In one embodiment, the incisor cap or occlusal pad of the base is provided with an arrow clip or interproximal hook to enhance the retention of the maxillary base.

[0009] In one embodiment, the extraoral arch includes a base segment and a traction segment, the base segment being embedded in the base of the maxillary base segment.

[0010] In one embodiment, the embedding position of the base segment is adjustable to adjust the direction of force applied by the extraoral arch to the maxillary base segment.

[0011] In one embodiment, the external bow is movably connected to the base via a pre-formed external bow tube.

[0012] The aforementioned headgear-mounted invisible muscle stimulator controls the vertical height of the maxillary anterior and posterior teeth, controls the protrusion of the maxillary anterior teeth, guides the mandible forward, and can also depress the mandibular anterior teeth to prevent the elongation of the mandibular posterior teeth, thereby controlling the occlusal plane, reducing the posterior-inferior rotation of the mandible, and achieving the anterior-superior rotation (counterclockwise rotation) of the mandible.

[0021] The following is combined Figures 1-3 This invention describes a headgear-mounted invisible muscle stimulator.

[0022] like Figure 1 As shown, in one embodiment, a headgear-mounted concealed muscle stimulator includes: The maxillary base 1 includes a base 3 and an extraoral arch 4. The base 3 has an upper occlusal pad 5 on the occlusal surface of the posterior teeth region, and the upper occlusal pad 5 has an upper guide slope 7. The mandibular invisible part 2 is composed of a shell-shaped invisible orthodontic appliance 13. It has a lower occlusal pad 6 on the occlusal surface of its posterior teeth region or anterior teeth region, and the lower occlusal pad 6 has a lower guide slope 8.

[0023] Among them, the upper occlusal pad 5 is located behind the lower occlusal pad 6, and the upper guide slope 7 and the lower guide slope 8 coincide during occlusion, which assists in guiding the mandibular incisor ends to align with the maxillary incisor ends; the multiple shell-shaped clear aligners 13 of the mandibular invisible part 2 have inconsistent positions and heights of the lower anterior teeth, and cover the crown portion 14 of the mandibular teeth.

[0024] The headgear-style invisible muscle stimulator of this embodiment, through its split design (maxillary base 1 and mandibular invisible part 2) and guiding inclined surface occlusal guidance structure, stimulates mandibular bone development while guiding the mandible forward. At the same time, it uses multiple shell-shaped invisible aligners 13 with gradually varying heights to progressively depress the lower anterior teeth, effectively preventing loss of occlusal plane control caused by the elongation of the lower posterior teeth. Combined with the vertical control of the maxilla by the extraoral arch 4, it ultimately achieves anterior and superior rotation (counterclockwise rotation) of the mandible, improving the lower 1 / 3 height and small chin appearance of patients with high-angle mandibular retrusion. It solves the problem that the elongation of the lower posterior teeth aggravates vertical deformities in traditional muscle stimulator treatment.

[0025] In this embodiment, the base 3 of the maxillary denture base 1 includes a main body 9, an occlusal pad 5, and an incisor cap 10. The main body 9 connects the occlusal pad 5 and the incisor cap 10. The occlusal pad 5 covers the maxillary posterior teeth, and the incisor cap 10 covers the incisal edges and labial surfaces of the maxillary anterior teeth. By integrating the main body 9, the occlusal pad 5, and the incisor cap 10 into one unit through the base 3, the occlusal pad covers the occlusal surfaces of the maxillary posterior teeth to control the vertical height, and the incisor cap covers the incisal edges and labial surfaces of the maxillary anterior teeth, effectively limiting the labial tilting of the maxillary anterior teeth due to force during treatment and enhancing the overall retention stability of the maxillary denture base.

[0026] In this embodiment, the incisor cap 10 is equipped with a double-curved labial arch to limit the labial tilt of the upper anterior teeth. The double-curved labial arch of the incisor cap 10 actively applies lingual force to the upper anterior teeth, suppressing compensatory labial tilt during mandibular advancement and maintaining the coordination of the sagittal relationship of the dental arches after orthodontic treatment.

[0027] In this embodiment, the incisor cap 10 or occlusal pad 5 of the base 3 is provided with an arrow clip or interproximal hook to enhance the retention of the maxillary base 1. The addition of the arrow clip or interproximal hook to the incisor cap 10 or occlusal pad 5 significantly improves the anti-dislocation ability of the maxillary base 1 when worn intraorally, especially resisting the reverse force during extraoral arch traction.

[0028] In this embodiment, the extraoral arch 4 includes a base segment 11 and a traction segment 12. The base segment 11 is embedded in the base 3 of the maxillary base segment 1. The base segment 11 of the extraoral arch 4 is embedded in the base 3 to form a rigid connection. The traction segment 12 has an external cap that applies corrective force to achieve precise traction of the maxilla posteriorly and superiorly.

[0029] In this embodiment, the embedding position of the base segment 11 is adjustable to adjust the direction of force applied by the extraoral arch 4 to the maxillary base segment 1. The adjustable embedding position of the base segment 11 allows the direction of force applied by the extraoral arch to be dynamically adjusted according to clinical needs, specifically inhibiting maxillary protrusion and excessive vertical development.

[0030] In this embodiment, the extraoral arch 4 is movably connected to the base plate 3 via a pre-formed extraoral arch tube. This movable connection allows for convenient removal of the extraoral arch (e.g., during daytime activities), maintaining orthodontic function while also considering the patient's aesthetic and comfort needs.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
