MRC silicone braces are often made of medical-grade silicone or similar materials. Silicone braces are usually standardized in design, and it is difficult to perform precise correction design and force control according to the specific situation of each patient; 2. Large size and poor comfort; 3. Limited indications. MRC, also known as myofunctional regulator, is mainly suitable for tooth arrangement problems caused by myofunctional dysfunction. For other types of tooth arrangement problems, MRC is not the best treatment option. It can only achieve simple early correction and is not suitable for complex cases. It is not suitable for patients with skeletal Class III, moderate to severe dental arch stenosis, moderate to severe dental crowding, moderate to severe skeletal malocclusion and eccentric jaw, vertical overdevelopment, etc.; 4. Silicone materials are not stable; 5. The treatment cycle is long, and the treatment effect is not immediate; 6. The cost is high; 7. It is easy to cause labial inclination of the lower incisor, which is not good for skeletal Class II patients.

It can easily cause labial inclination of the lower incisor, which is not good for patients with skeletal Class II; 7. It is more suitable for dental or functional malocclusion, and the effect on skeletal malocclusion is poor.

[0005] Disadvantages of the activator: 1. The base area is large, and the patient is not comfortable wearing it and is prone to nausea; 2. The force of the labial arch to retract the upper front teeth is small and cannot lower the upper front teeth, so the inhibitory effect on the forward and downward growth of the maxilla is poor and needs to be combined with an extraoral arch; 3. For patients with narrow upper dental arches, the maxillary expansion effect is not good; 4. For patients with open lips and exposed teeth, the pendulum effect cannot be eliminated when the labial arch is retracted, causing excessive exposure of the upper front teeth; 5. It is easy to cause lip inclination of the lower incisor, which is not good for skeletal Class II patients; 6. Bad habits cannot be corrected.

[0006] Disadvantages of vestibular shield: 1. Limited indications. It is more suitable for correcting bad habits and is not suitable for complex cases. 2. Limited maxillary expansion effect. 3. Cannot perform vertical control on patients with high angles. 4. Can easily cause lip inclination of lower incisor, which is not good for patients with skeletal Class II. 5. Limited use.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0019] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] It should be noted that the related terms lingual side, labial side, buccal side, gingival-maxillary direction, mesiodistal direction, and distal direction are industry terms for orthodontic treatment. In the lateral direction, the side adjacent to the lips in the anterior teeth area is called the labial side, the side adjacent to the buccal mucosa in the posterior teeth area is called the buccal side, and the side adjacent to the tongue is called the lingual side. The surfaces of the teeth are respectively called the labial side (anterior teeth area), buccal side (posterior teeth area), and lingual side. In practice, the sides adjacent to the labial side and buccal side of the anterior teeth area and the posterior teeth area, respectively, are collectively referred to as the labial and buccal sides. The surface in contact with the adjacent teeth is called the adjacent surface, among which the side close to the anterior teeth is called the mesial side, and the side far from the anterior teeth is called the distal side. The tooth surfaces are respectively called the mesial surface and the distal surface.

[0021] It should be noted that the term “and / or” is used as a functional word indicating that two words or expressions are used together or separately. For example, A and / or B includes A alone, B alone, and A and B together.

[0022] Example 1 Reference Figure 1-Figure 4 As shown, this embodiment provides a personalized functional orthodontic appliance, including an orthodontic appliance body 1, the orthodontic appliance body 1 is in the shape of a dental arch, the upper surface of the orthodontic appliance body 1 has an upper alveolar concave downward to wrap the upper dentition, and the lower surface of the orthodontic appliance body 1 has a lower alveolar concave upward to wrap the lower dentition; The appliance body 1 is provided with a vestibular closure blunt 2 and a buccal guard 3; Therefore, the personalized functional orthodontic appliance also includes a mandibular jaw positioning module, which includes a first concave-convex structure provided on the occlusal surface of at least part of the anterior teeth area in the upper alveolar socket, and a second concave-convex structure provided on the occlusal surface of at least part of the anterior teeth area in the lower alveolar socket. The first concave-convex structure is concavely matched with the corresponding occlusal surface of the maxillary anterior teeth, and the second concave-convex structure is concavely matched with the corresponding occlusal surface of the mandibular anterior teeth.

[0023] The personalized functional appliance in this embodiment is positioned by the first concave-convex structure and the second concave-convex structure provided in the front teeth area respectively cooperating with the concave-convex occlusal surfaces of the upper and lower front teeth.

[0024] In this embodiment, all or part of the anterior teeth corresponding to the upper and lower alveoli (upper and lower alveoli) are designed with anatomical occlusal surfaces, and the posterior teeth are designed with non-anatomical / anatomical occlusal surfaces, which facilitates the precise control of the three-dimensional direction of the mandibular occlusion, and has the effect of active / passive arch expansion, and has the function of occlusal induction to enable the posterior teeth to close.

[0025] When the orthodontic appliance in this embodiment is used for patients with severe skeletal asymmetry, step-by-step correction can be achieved.

[0026] In one embodiment, a lip stopper is further provided on the appliance body 1. The lip stopper in this embodiment is a personalized lip stopper.

[0027] In one embodiment, the height of the lip guard is adjusted to the bottom of the vestibule groove, or the height of the lip guard is adjusted to have a gap of 0.1-3mm with the bottom of the vestibule groove. By adjusting the height of the lip guard to have a gap of 0.1-3mm with the bottom of the vestibule groove, the mentalis muscle can be stretched and its tension can be reduced, which is conducive to the improvement of the chin shape. Furthermore, in this embodiment, the lip guard can be designed on the upper jaw / mandible or both jaws, or on one side, and can be designed in different forms according to actual conditions. In addition, it should be noted that the lip guard in this embodiment can be realized by a large connector / small connector or an overall integrated design, including but not limited to traditional base support type / arch wire + base support type / 3D printing / cast base support type / cast steel wire + base support / 3D printing shell mold + injection molding process and the like.

[0028] The lip stopper in this embodiment includes an upper lip stopper 4 and a lower lip stopper 5 .

[0029] The lip guard in this embodiment is designed according to individual needs, with the lip side extending outward by about 0.5-2mm, and the gingival side extending to the bottom of the vestibule groove or extending 0.1-3mm to the bottom of the vestibule groove. The lip guard design can easily achieve the following: (1) isolating the pressure on the dental arch caused by the tight lip muscles; (2) extending toward the gingival side to stimulate the bone mucosa to achieve osteogenesis of the alveolar basal bone and expand the basal bone arch, thereby achieving passive expansion of the dentition and basal bone arch.

[0030] In one embodiment, the upper and lower sides of the buccal shield 3 extend to the bottom of the upper and lower vestibule grooves respectively, the thickness of the buccal shield 3 is 2.5-3mm, and the gap between the buccal shield 3 and the buccal side of the maxillary posterior alveolar bone is 0-3mm. The buccal shield 3 in this embodiment is used for bone mucosal stimulation, and the height of the buccal shield 3 extends to the bottom of the vestibule groove, especially the maxillary first bicuspid and the maxillary tuberosity. The upper front edge reaches the root of the maxillary canine, and the buccal shield 3 is 0-3mm away from the buccal side of the maxillary posterior alveolar bone. Stimulating the maxillary buccal mucotympanic membrane, the upper part can eliminate the unbalanced muscle force of the buccal muscle and promote the lateral expansion of the maxillary dental arch. It should be noted that the specific thickness of the buccal shield 3 in this embodiment is personalized and designed according to the amount of arch expansion. The buccal shield 3 is conducive to stretching the buccal muscle, reducing the tension of the buccal muscle on the posterior teeth, and is conducive to the expansion of the posterior teeth.

[0031] In this embodiment, the vestibular seal blunt 2 is retained in the mouth by the contraction force of the lip and cheek muscles to form a physical barrier, which mainly relies on muscle function to help break bad habits such as sucking fingers, biting lips, and breathing with the mouth open.

[0032] In one embodiment, a breathing hole 6 is provided on the vestibular closure blunt 2, and the breathing hole 6 is provided to assist the mouth-breathing patient to establish nasal breathing in the early stage of wearing the device to prevent breath holding; it should be noted that in this embodiment, there is no restriction on the design quantity, position, shape, and formation process of the breathing holes 6 (including but not limited to 3D printing / drilling design / insertion of small tubular design) of the breathing holes 6.

[0033] In one embodiment, the personalized functional appliance further comprises a tongue positioning training device, through which the tongue is guided to a normal position to break bad tongue habits. The tongue positioning training device in this embodiment includes but is not limited to tongue positioning training devices such as tongue concave / palatal bead / tongue ladder / tongue fence.

[0034] In one embodiment, the upper alveolar tooth includes an upper tooth occlusal surface, an upper tooth lingual side surface, and an upper tooth buccal side surface, and the hardness of the upper tooth lingual side surface is less than the hardness of the upper tooth buccal side surface; the lower alveolar tooth includes a lower tooth occlusal surface, a lower tooth lingual side surface, and a lower tooth buccal side surface, and the hardness of the lower tooth lingual side surface is less than the hardness of the lower tooth buccal side surface.

[0035] In this embodiment, the hardness of the lingual side is greater than the hardness of the buccal side. The high hardness of the outside (lingual side) plays a supporting role and can maintain the inherent shape of the orthodontic appliance, which is beneficial to the stability of the occlusion and the performance of the function. The soft design of the inside (buccal side) can increase the comfort of wearing the braces.

[0036] In one embodiment, a gap is formed between the lingual side surface of the upper teeth and the lingual side surface of the upper teeth in the upper alveolar socket, and a gap is formed between the lingual side surface of the lower teeth and the lingual side surface of the lower teeth in the lower alveolar socket.

[0037] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
