Description

Technical Field

[0001] The utility model relates to the technical field of oral medicine, in particular to an anterior tooth shaper. Background Art

[0002] Due to the malposition of the upper and lower anterior teeth (deep overbite and deep overjet), there is an obstacle to the closure of the upper and lower lips, and the upper and lower lips cannot close naturally. The most common closure obstacle is that the upper anterior teeth are labially inclined or protruded, resulting in the relaxation of the upper lip and insufficient functional development of the upper lip, manifested as a short upper lip. Due to the anteroposterior malposition of the upper and lower anterior teeth, the lower anterior teeth are located behind the upper anterior teeth, creating a large gap between the upper and lower anterior teeth. The lower lip often fills this space, leading to eversion of the lower lip and deepening of the mentolabial sulcus. If not effectively corrected during the growth and development period of children, it is difficult to make up for it after passing the growth and development period, resulting in a permanent short upper lip, and it is even more difficult to correct in adulthood.

[0003] For patients with deep overbite and deep overjet, due to the large anteroposterior position difference between the upper and lower anterior teeth, currently only the vestibular shield is used for correction. However, since the degree of relaxation of the upper and lower lips in such patients is also different, the goals of lip muscle training are also different. The goal of upper lip muscle function training is to extend the upper lip, and the goal of lower lip muscle function training is to tighten the lower lip and reduce the eversion of the lip. For different lip muscle training goals, the traditional rigid vestibular shield or the vestibular shield made by reducing the gap between the upper and lower anterior teeth after mandibular protrusion still cannot meet the requirements, and there will also be a situation of unstable wearing. For children, it is difficult to maintain the mandibular protrusion position for a long time.

[0004] The "occlusion" in the present utility model is a professional term in stomatology, and its English is occlusion. The character "牙合" is composed of the left and right parts of a single Chinese character, and it cannot be found in the common font library, so it is written separately as "牙合". Content of the Utility Model

[0005] The purpose of the present utility model is to overcome the defects existing in the prior art, and to provide an anterior tooth shaper that can be used for both tooth correction and lip muscle training.

[0006] The purpose of the present utility model can be achieved through the following technical solutions:

[0007] The technical solution of the present utility model is to provide an anterior tooth shaper, which is arranged between the human dentition and the lips and cheeks, and includes an arc-shaped plate body adapted to the oral vestibule.

[0008] The arc-shaped plate body includes an upper lip induction section for covering the upper teeth and a lower lip induction section for covering the lower teeth and supporting the lower lip. The arc-shaped plate body includes an upper lip induction section for covering the upper teeth and a lower lip induction section for covering the lower teeth and supporting the lower lip. A lip line facing the lips and filling the gap between the upper and lower lips is provided at the junction of the upper lip induction section and the lower lip induction section. The upper part of the lower lip induction section is an incisal end cap that protrudes toward the upper front teeth and rests against the incisal end of the upper front teeth.

[0009] In some specific embodiments, the upper edge of the arc-shaped plate body is provided with a plurality of grooves for avoiding the frenulum of the lips and cheeks of the oral cavity.

[0010] In some specific embodiments, there are three grooves, which are used to avoid the buccal frenulum on the left side of the oral cavity, the lip frenulum in the middle of the oral cavity, and the buccal frenulum on the right side of the oral cavity, respectively.

[0011] In some specific embodiments, the groove and the arc-shaped plate bodies on both sides have a height range of (1.0-3.0) cm.

[0012] In some specific embodiments, taking the horizontal plane where the lip line is located as the reference plane, the tangent angle between the reference plane and the upper lip induction section is in the range of 73° to 91°, the tangent angle between the reference plane and the lower lip induction section is in the range of 45° to 78°, and the tangent angle between the reference plane and the cut end cap is in the range of 2° to 26°.

[0013] The tangent line between the reference plane and the upper lip induction section can be understood as: taking the connection point between the lip line and the arc-shaped plate body as the starting point, a ray is drawn out, and rotated counterclockwise to the section that is first tangent to the upper lip induction section. The ray at this time serves as the tangent line between the reference plane and the upper lip induction section.

[0014] Similarly, the tangent line between the reference plane and the lower lip induction section can be understood as: taking the connection point between the lip line and the arc-shaped plate body as the starting point, drawing out a ray, rotating clockwise to the section that is first tangent to the lower lip induction section, and the ray at this time serves as the tangent line between the reference plane and the lower lip induction section.

[0015] The tangent line between the reference plane and the cutting end cap can be understood as: starting from the connection point between the lip line and the arc-shaped plate body, a ray is drawn out, and it rotates counterclockwise to the section that is first tangent to the cutting end cap. The ray at this time serves as the tangent line between the reference plane and the cutting end cap.

[0016] The thickness of the curved plate body can be ignored.

[0017] In some specific embodiments, the width of the arc-shaped plate body ranges from (0.5-12) cm; the arc length of the arc-shaped plate body ranges from (3-17) cm.

[0018] In some specific embodiments, the lip line is a flat shape that protrudes toward the lips at the junction of the upper lip induction section and the lower lip induction section.

[0019] In some specific embodiments, the length of the lip line ranges from 1 to 5 mm, the width of the lip line ranges from 2 to 3 cm, and the thickness of the highest point of the lip line ranges from 1 to 3 mm.

[0020] The length direction of the lip line can be understood as the perpendicular direction between the lip line and the arc-shaped plate body. Similarly, the width direction of the lip line can be understood as the perpendicular direction to its length.

[0021] In some specific embodiments, the edges of the curved plate body are further provided with protective pieces that protrude in a direction away from the tongue side and are used to protect the upper and lower gums.

[0022] In some specific embodiments, the angle between the protective member and the arc-shaped plate body is 10-80°.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention separately designs the upper lip guide section and the lower lip guide section, so that the upper lip wraps around the upper lip guide section, and the lower lip can also obtain support from the lower lip guide section, forming a normal lip wrap. In addition, multiple grooves are provided on the upper edge of the arc-shaped plate body, which can effectively avoid the oral lip and cheek frenulum at the corresponding position, avoiding affecting the contraction of the lip muscles and other activities.

[0025] (2) The present invention, through the design of the lip line, can guide the upper lip to stretch downward and guide the lower lip to tighten so that it does not exceed the lip line, thereby eliminating the gap between the upper and lower lips, inducing the lips to close and form a directional pressure, so that the upper and lower lips close and grow on a smooth base surface, restoring their proper shape and lip muscle tension. The traditional vestibular shield, on the other hand, is a smooth surface without the guidance of the lip line, which may cause the lower lip to be overstretched and the upper lip to be understretched.

[0026] (3) The incisor cap of the present invention is designed to be semi-wrapped against the incisal ends of the upper front teeth. When the oral lip muscles contract, the lip line and the incisor cap work together to generate the retraction and pressing force of the upper front teeth. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0037] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments and features may be combined with each other unless they conflict. Any functional component or structure not specifically described is a conventional component or structure used in the art to achieve the corresponding function.

[0038] like Figure 1-6 As shown, a front teeth shaper is provided between the human dentition and the lips and cheeks, comprising an arc-shaped plate body 1 adapted to the oral vestibule, the arc-shaped plate body 1 comprising an upper lip induction section 1-1 for covering the upper teeth and a lower lip induction section 1-2 for covering the lower teeth and supporting the lower lip, a lip line 2 facing the lips and filling the gap between the upper and lower lips is provided at the junction of the upper lip induction section 1-1 and the lower lip induction section 1-2, the upper part of the lower lip induction section 1-2 being an incisal end cap 3 protruding toward the upper front teeth and resting against the incisal end of the upper front teeth.

[0039] The technical solution of this embodiment is to realize the training of the oral lip muscles and the correction of the upper and lower front teeth through the action of the lip line 2 and the incisal cap 3 and the synergistic action between the two. The lip line 2 on the arc-shaped plate body 1 can guide the upper lip to stretch downward and guide the lower lip to tighten not exceeding the lip line 2, thereby eliminating the gap between the upper and lower lips, inducing the lips to close to form directional pressure, so that the upper and lower lips close, grow, and restore their proper shape and lip muscle tension on the smooth base surface. The incisal cap 3 is semi-wrapped against the incisal end of the upper front teeth. On the one hand, it can be used to locate the position of the upper front teeth. On the other hand, when the oral lip muscles contract, the synergistic action of the lip line 2 and the incisal cap 3 can generate the inward and pressing force of the upper front teeth. In addition, the arc-shaped design of the upper lip induction section 1-1 and the lower lip induction section 1-2 is more in line with the space between the teeth and the lips and cheeks, which is conducive to the formation of normal lip wrapping.

[0040] The lip and cheek frenulum plays an important role in oral function and helps the activities of the lip and cheek muscles. Therefore, it does not affect normal oral activities. Figure 2 As shown, the upper edge of the arc-shaped plate body 1 is provided with a plurality of grooves 4 for avoiding the lip and cheek frenulum of the oral cavity. Preferably, the grooves 5 are provided with three, respectively for avoiding the left buccal frenulum of the oral cavity, the middle lip frenulum of the oral cavity, and the right buccal frenulum of the oral cavity.
