Description

Technical Field

[0001] The utility model relates to the technical field of oral orthodontic appliances, in particular to a caput galea excitobilis appliance with a lower lip stop. Background Art

[0002] Angle Class II malocclusion is a common malocclusion in adolescents, with an incidence rate of up to 23% in adolescents. Its typical clinical manifestations are: relative protrusion of the maxilla, retrusion or underdevelopment of the mandible, narrow upper and lower dental arches, narrowing of the posterior maxillary dental arch relative to the mandibular dental arch when the mandible moves forward, high arched palate, protrusion of the upper front teeth, and compensatory lip inclination of the lower front teeth.

[0003] For the correction of this type of malocclusion, the "dual-stage correction" method is often adopted clinically, that is, to correct bone problems during the active growth period and to correct dental problems after the permanent teeth are fully occluded. For the early correction of such situations, functional appliances are widely used clinically, such as patent number CN219354209U, named a muscle activator, including a base member, the base member is provided with a maxillary support, a mandibular support and an alveolar part, the front end of the base member is connected to an induction wire member, and a continuous orthopedic force is applied to the mandible through the maxillary support and the mandibular support, and the incisor is fixed by the alveolar part to inhibit its eruption direction, and the force pulling the mandible is transmitted to the upper dental arch and maxilla through the induction wire member, effectively inhibiting the forward development of the maxilla.

[0004] However, since the muscle activator disclosed in the above-mentioned prior art can inhibit the development of the maxillary bone and guide the mandible forward to promote occlusal reconstruction during correction, this muscle activator cannot stimulate the development of the mandibular bone and cannot eliminate the tension of the mentalis muscle, it is not conducive to fundamentally improving the closing state of the lower lip.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the following description is only a part of the embodiment of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these embodiments without creative work. Example 1

[0027] Reference Figure 1-6 The utility model provides a head cap muscle activating appliance with a lower lip stop, comprising a muscle activating appliance body 1, a maxillary lip arch 2 and a lower lip stop 3 are arranged at the front end of the muscle activating appliance body 1, the maxillary lip arch 2 is clamped on the gums of the patient's two upper canines, and the lower lip stop 3 is located in the oral vestibule of the patient's lower lip.

[0028] Specifically, the activator body 1 includes a base 11, a palatal ring 12 and two extraoral bows 13. The base 11 is made of self-curing resin (the main component is polymethyl methacrylate). The base 11 is generally consistent with the head cap activator orthodontic appliance in the prior art, that is, the base 11 is arched upward and downward to form a hollow cavity for adjusting the sagittal relationship between the maxillary and mandibular bones. The palatal ring 12 is fixedly connected to the rear end of the base 11 on the patient's palate side. When swallowing, the palatal ring 12 transmits the upward and backward pressure of the tongue to increase the stability of the orthodontic appliance. The two extraoral bows 13 are fixedly connected to the front end of the base 11, and the two extraoral bows 13 extend out of the oral cavity respectively from the corresponding positions of the two upper incisors. One end of the extraoral bow 13 extending to the outside of the oral cavity is hung with the head cap. In this embodiment, the palatal ring 12 and the extraoral bow 13 are made of steel wire with a diameter of 1.2 mm.

[0029] like Figure 3 As shown, the front end of the base 11 is integrally connected with a maxillary incisor cap 111 and a mandibular incisor cap 112, the maxillary incisor cap 111 corresponds to the position of the patient's upper central incisor, upper lateral incisor and upper canine, the mandibular incisor cap 112 corresponds to the position of the patient's lower central incisor, lower lateral incisor and lower canine, and the mandibular incisor cap 112 covers at least 1 / 3 of the lower incisor, and the interior of the maxillary incisor cap 111 and the mandibular incisor cap 112 are both provided with grooves for accommodating corresponding teeth.

[0030] The maxillary labial arch 2 includes an arc-shaped component 21, the curvature of the arc-shaped component 21 is the same as and parallel to the curvature of the base 11 at the incisor, and both ends of the arc-shaped component 21 are provided with an upwardly protruding inverted U-shaped component 22. The arc-shaped component 21 and the inverted U-shaped component 22 are integrally formed, and the arc-shaped component 21 is fixedly connected to the activator body 1 through the inverted U-shaped component 22. The maxillary labial arch 2 replaces most of the base at the front end. When the patient uses this orthodontic appliance, the inverted U-shaped components 22 at both ends are clamped and supported on the gums of the patient's two upper canines, thereby inhibiting the upper dental arch from protruding outward and growing.

[0031] like Figure 2-5 As shown, the lower lip blocking portion 3 includes an arched support member 31 and two blocking members 32. Both ends of the arched support member 31 are fixedly connected to the activator body 1. The arched support member 31 is a U-shaped structure and extends from the inside of the activator body 1 to the oral vestibule of the patient's lower lip. The two blocking members 32 are both wrapped on the arched support member 31, and are 3 to 5 mm apart from each other at one end. More specifically, the arched support member 31 is made of a steel wire with a diameter of 1.0 mm, and the blocking member 32 is made of the same material as the base 11. The blocking member 32 is ellipsoidal in shape, and the thickness of the blocking member 32 at the maximum cross-section is 2.5 to 3 mm. The edge of the blocking member 32 is rounded and smooth, and will not cause damage to the mucosa of the patient's oral vestibule.

[0032] Furthermore, the upper edge of the blocking member 32 is located above the patient's gums and 3 to 5 mm away from the gum edge. The outer edge of the blocking member 32 does not exceed the gingival protrusion of the patient's lower canines, thereby preventing the patient from feeling uncomfortable while speaking and scratching the lip mucosa. The lower edge of the blocking member 32 penetrates into and abuts against the bottom of the patient's vestibule groove, thereby eliminating the tension of the patient's mental muscles, shallowing the chin-labial groove, improving the patient's lower lip posture, and reducing the direct effect of the lower lip on the teeth, which is beneficial to lip closure practice. Example 2

[0033] A caput galea excitation appliance with a lower lip stop, when used:

[0034] The activator body 1 is placed in the patient's oral cavity, so that the top of the base 11 is in contact with the patient's palate, the tongue is in the hollow cavity at the bottom of the base 11, the arc-shaped member 21 is located outside the upper central incisor and the upper lateral incisor, and the inverted U-shaped members 22 at both ends of the arc-shaped member 21 are in contact with the gums of the two upper canines. The lower lip stopper 3 is located in the patient's oral vestibule, and the arch support member 31 is adjusted so that the outer edges of the two stoppers 32 do not exceed the gum ridges of the lower canines, and at the same time, the lower edges of the two stoppers 32 are deep into the patient's vestibule. After the adjustment of the groove bottom is completed, the outer ends of the two extraoral arches 13 are hung with the head cap, so that the patient wears the orthodontic appliance of the utility model to practice lip closure and correct mental muscle tension, which is beneficial to improve the inherent posture of the patient's lower lip, shallower the chin-labial groove, and promote the normal development of the mandible; the patient wears the orthodontic appliance in the position of mandibular protrusion and jaw reconstruction, and the orthodontic appliance forms a backward reaction force on the maxilla, which plays a role in inhibiting the development of the maxilla, and then under the traction of the extraoral arch, the effect of inhibiting the maxilla is more obvious.

[0035] It should be noted that the above is only an exemplary description of the structure of the orthodontic appliance. When it is actually used clinically, it needs to be personalized according to the actual situation of each patient. First, take the patient's upper and lower jaw models. Bite reconstruction is required before making the orthodontic appliance. The method is to let the patient open his mouth as much as possible and extend his lower jaw forward, and use softened wax to obtain the bite reconstruction record. The patient's lower jaw is not moved forward more than 6mm, and is opened vertically beyond the rest gap. Then the orthodontic appliance structure as in this application is made according to the bite reconstruction record.

[0036] It should be clear that the above detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
