Description

Technical Field

[0001] The invention relates to the field of dental medical instruments, and in particular to a head cap invisible muscle activator and a manufacturing method thereof. Background Art

[0002] The mandibular development is insufficient in adolescent patients with skeletal Class II high-angle malocclusion, which is manifested by mandibular retraction, increased ANB angle, and distal relationship of molars. In addition to sagittal relationship abnormalities, it is also accompanied by vertical relationship abnormalities and abnormal growth and development. The formation of skeletal Class II is caused by the uncoordinated development of the upper and lower jaws. The reasons are severe underdevelopment of the mandible, weak vertical growth of the condyle, and strong vertical growth of the posterior alveolar of the maxilla and mandible and forward growth of the maxilla, which together lead to the posterior-inferior rotation of the mandible (clockwise rotation), and the posterior-inferior rotation of the mandible further aggravates the vertical abnormality.

[0003] The capitula activator is usually used to control the vertical height of the maxillary anterior and posterior teeth and the protrusion of the maxillary anterior teeth, while advancing the mandible and inducing the development of the mandible. However, patients with skeletal Class II high-angle malocclusion are also divided into deep anterior overbite and open anterior overbite. If there is a deep anterior overbite, after the mandible is advanced, the coverage of the upper and lower anterior teeth decreases, and a gap appears between the upper and lower posterior teeth. When the capitula activator is removed, the lower posterior teeth will be elongated until all the posterior teeth are in contact to stabilize the occlusal relationship. Since the elongation of the lower posterior teeth will cause the mandible to rotate posteriorly and inferiorly, thereby aggravating the vertical abnormality, it is necessary to lower the lower posterior teeth through bone screws and other means in the later stage, which increases the difficulty of later correction. However, for patients with high-angle mandibular retrusion and deep anterior overbite, the treatment goal is to achieve anterior-superior rotation of the mandible (counterclockwise rotation) and reduce the height of the lower 1 / 3 of the face. Therefore, the current caput galactimeter activator is not suitable for the treatment of patients with skeletal Class II high-angle mandibular retrusion and deep overbite of the lower anterior teeth. Summary of the invention

[0004] In view of the above-mentioned deficiencies existing in the background technology, the object of the present invention is to provide an invisible muscle activator of a head cap to control the vertical height of the front and rear teeth of the maxillary teeth, control the protrusion of the upper front teeth, guide the mandible forward, and at the same time depress the lower front teeth to prevent the elongation of the lower posterior teeth, thereby controlling the occlusal plane, reducing the posterior-inferior rotation of the mandible, and achieving the anterior-superior rotation of the mandible (counterclockwise rotation).

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A head cap invisible muscle activator, comprising: The maxillary base part and the mandibular invisible part, the maxillary base part includes a base and an extraoral arch, the base is provided with an upper pad on the occlusal surface of the posterior teeth area, the mandibular invisible part is composed of one or more shell-shaped invisible orthodontic appliances, and a lower pad is provided on the occlusal surface of the posterior teeth area or the anterior teeth area, and the upper pad is located behind the lower pad, the upper pad and the lower pad are respectively provided with upper guide bevels and lower guide bevels at corresponding positions for auxiliary guidance during occlusion, so that the upper and lower jaws overlap at the guide bevel position when occluding, and the mandibular incisor end and the maxillary incisor end tend to be aligned.

[0006] When the upper and lower jaws occlude, the upper guide bevel of the upper pad contacts the lower guide bevel of the lower pad, thereby pushing the mandibular invisible part forward. Since the mandibular invisible part is worn on the crown of the mandibular teeth, the entire mandible is pushed forward, thereby stimulating the development of the mandibular bone.

[0007] A further preferred embodiment of the above technical solution is that the base of the maxillary base portion includes a main body, an upper closure pad and an incisor cap, the main body connects the upper closure pad and the incisor cap, the upper closure pad covers the maxillary posterior teeth, and the incisor cap covers the incisal end and labial side of the maxillary anterior teeth.

[0008] A further preferred embodiment of the above technical solution is as follows: the extraoral bow comprises a base section and a traction section, and the base section is embedded in the base of the maxillary base part.

[0009] By adopting the above solution, further: the traction section of the extraoral arch is connected to the head cap, so as to apply upward and backward force to the entire maxillary base. The embedding position of the extraoral arch base section can be adjusted, so as to adjust the force direction of the maxillary base.

[0010] By adopting the above scheme, further: the one or more shell-shaped invisible braces of the mandibular invisible part cover the crowns of the mandibular teeth, the lower guide bevel of each shell-shaped invisible brace coincides with the upper guide bevel of the maxillary base part when the upper and lower jaws are occluded, and the lower front teeth positions of the multiple shell-shaped invisible braces are inconsistent in height.

[0011] The shell-shaped invisible orthodontic appliance lowers the lower front teeth step by step according to the conventional steps, and the lower occlusal pad is designed under the same lower guide bevel.

[0012] A method for manufacturing a head cap invisible muscle activator, comprising the following steps: Step 1: Determine the position of the upper and lower guide bevels on the 3D dental model; Step 2: Design the lower occlusal pad according to the position of the guide bevel and make the mandibular invisible part; Step 3: Install the mandibular model with mandibular invisible part and the maxillary model on the articulator; Step 4: Apply a separating agent on the surface of the mandibular invisible part, and make the maxillary base, so that the upper pad of the maxillary base and the lower pad of the mandibular invisible part overlap on the guide bevel; Step 5: The mandibular dental model is pressed down and decomposed into multiple three-dimensional models by interpolation method. The mandibular anterior teeth of each model are not in the same height, and the lower guide slope of each mandibular invisible part is made to coincide with the upper guide slope of the maxillary base part; Step 6: Make multiple shell-shaped invisible braces for the mandible.

[0013] Compared with the prior art, the present invention has the following beneficial effects: While controlling the vertical height of the maxillary anterior and posterior teeth and the protrusion of the upper anterior teeth and guiding the mandible forward, the lower anterior teeth can be pressed down to prevent the elongation of the lower posterior teeth, thereby controlling the occlusal plane, reducing the posterior-inferior rotation of the mandible, and achieving anterior-superior rotation of the mandible (counterclockwise rotation).

The traditional muscle activator is a base structure with upper and lower jaws integrated. The muscle activator designed by the present invention adopts a split structure with an upper jaw base part 1 and a lower jaw invisible part 2. Figure 1 The base of the maxillary base is integrally formed by resin, including an incisor cap 10 covering the incisal end and lip side of the maxillary anterior teeth, an upper pad 5 covering the maxillary posterior teeth, and a main body 9 covering the oral palate, see Figure 3 The mandibular invisible part is composed of one or more shell-shaped invisible appliances 13, and a lower pad 6 is provided on the occlusal surface of the posterior or anterior teeth area, and covers the crown part 14 of the mandibular teeth. The lower guide bevel 8 of each shell-shaped invisible appliance coincides with the upper guide bevel 7 of the maxillary base when the upper and lower jaws are occluded. The lower front teeth of the multiple shell-shaped invisible appliances are not in the same height. See Figure 1 and Figure 2 The extraoral bow is made of stainless steel wire and includes a base section 11 and a traction section 12, wherein the base section is embedded in the base of the maxillary base, see Figure 3 .

[0018] Arrowheads or interproximal hooks can be added to the upper occlusal pad or incisor cap to increase the retention of the maxillary base and prevent it from falling off when worn. A hyperbolic lip bow can be added to the incisor cap to prevent the labial tilt of the upper anterior teeth.

[0019] The prefabricated extraoral arch tube can be embedded in the base of the maxillary base, and the extraoral arch base section can be inserted into the extraoral arch tube to achieve a movable connection. When the patient goes to school during the day, he can remove the extraoral arch and only wear the maxillary base, which increases comfort and aesthetics.

[0020] When making a head cap invisible muscle activator, the main steps are as follows: Step 1: Determine the position of the upper and lower guide bevels on the 3D dental model; Step 2: Design the lower occlusal pad according to the position of the guide bevel, and use the conventional lamination method to make the lower jaw invisible part, or directly 3D print the lower jaw invisible part; Step 3: Install the mandibular model with the mandibular invisible part and the maxillary model on the articulator (the positions of the upper and lower mandibular models are installed according to the bite record provided by the doctor); Step 4: Apply a separating agent on the surface of the mandibular invisible part, and make the maxillary base, so that the upper pad of the maxillary base and the lower pad of the mandibular invisible part overlap on the guide bevel; Step 5: The mandibular dental model is pressed down and decomposed into multiple three-dimensional models by interpolation method. The mandibular anterior teeth of each model are not in the same height, and the lower guide slope of each mandibular invisible part is made to coincide with the upper guide slope of the maxillary base part; Step 6: Make multiple shell-shaped invisible orthodontic appliances for the mandible (to achieve the lowering of the lower front teeth).
