Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oral medicine, and particularly relates to an anterior tooth shaper and a manufacturing method thereof. 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, resulting in the eversion of the lower lip and the 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 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 of 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] "Occlusion" in the present invention 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 character, and it cannot be found in the common font library, so it is written separately as "牙合". Summary of the Invention
[0005] The purpose of the present invention is to overcome the defects existing in the prior art and to provide an anterior tooth shaper and a manufacturing method thereof, which can be used for both tooth correction and lip muscle training.
[0006] The purpose of the present invention can be achieved by the following technical solutions:
[0007] One of the technical solutions of the present invention is to provide an anterior tooth shaper, which is arranged between the human dentition and the lip and cheek, and includes an arc-shaped plate body adapted to the oral vestibule.
[0008] The arc 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 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 incision end cap that protrudes toward the upper front teeth and presses 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 lip and cheek frenulum 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, taking the horizontal plane where the lip line is located as the reference plane, the tangent angle range between the reference plane and the upper lip induction section is 73° to 91°, the tangent angle range between the reference plane and the lower lip induction section is 45° to 78°, and the tangent angle range between the reference plane and the cut end cap is 2° to 26°.
[0012] 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 it rotates 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.
[0013] Similarly, the tangent between the reference plane and the lower lip induction segment 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 segment, and the ray at this time serves as the tangent between the reference plane and the lower lip induction segment.
[0014] 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.
[0015] The thickness of the curved plate body can be neglected.
[0016] 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; and the height of the recess and the arc-shaped plate body 1 on both sides ranges from (1.0-3.0) cm.
[0017] 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.
[0018] 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.
[0019] The direction where the length of the lip line is located can be understood as the vertical direction between the lip line and the arc-shaped plate body. Similarly, the direction where the width of the lip line is located can be understood as the direction vertical to its length.
[0020] In some specific embodiments, the edges of the arc-shaped 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.
[0021] In some specific embodiments, the angle between the protective member and the arc-shaped plate body is 10-80°.
[0022] A second technical solution of the present invention is to provide a method for manufacturing the anterior teeth shaping device as described in one of the above technical solutions, comprising the following steps:
[0023] S1. Obtaining a digital dental model: obtaining a digital dental model, wherein the digital dental model includes a digital dental model body and a digital lip inclination;
[0024] S2. Designing an anterior teeth shaper: designing an arc plate body, lip line, incisal cap, recess, and protective part of the anterior teeth shaper based on the digital jaw model;
[0025] S3, molding: a preparation method of first hot pressing and then cutting or a direct 3D printing method.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] (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, thereby forming a normal lip wrap. A plurality of grooves are provided on the upper edge of the arc-shaped plate body, which can effectively avoid the lip and cheek frenulum at the corresponding position of the mouth and avoid affecting the contraction of the lip muscles and other activities.
[0028] (2) The present invention can guide the upper lip to stretch downward and guide the lower lip to tighten so as not to exceed the lip line, thereby eliminating the gap between the upper and lower lips, inducing the lips to close to form a directional pressure, so that the upper and lower lips can close, grow, and restore their proper shape and lip muscle tension on a smooth base surface. The traditional vestibular shield is a smooth surface without lip line guidance, which may cause the lower lip to be overstretched and the upper lip to be understretched.
[0029] (3) The incisor cap designed in the present invention is semi-wrapped against the incisal end of the upper front teeth. When the labial muscles contract, the lip line and the incisor cap cooperate to generate the retraction and compression force of the upper front teeth.
[0030] (4) The present invention obtains anterior teeth shaping device through digital design and production, which is convenient and fast, can efficiently adapt to different types of anterior teeth deep overbite and deep overjet, and can form a good lip shape in combination with lip muscle training. It replaces the cumbersome production process of the traditional vestibular shield: pouring plaster, fixing the occlusal relationship on the model frame, covering the surface of the anterior teeth and premolars with wax models, then coating self-curing plastic, injection molding wax models, boxing, wax removal, filling plastic, putting in hot water to solidify the plastic, grinding and polishing, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention is described in detail below in conjunction with 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.
[0040] 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, further definition and explanation thereof is not required in subsequent drawings.
[0041] In the following, some embodiments of the present invention are described in detail in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. If there is no special description of functional components or structures, it means that they are all conventional components or conventional structures used in the art to achieve corresponding functions.
[0042] like Figure 1-6 As shown, a front teeth shaper is arranged between the human dentition and the lips and cheeks, including an arc-shaped plate body 1 adapted to the oral vestibule, the arc-shaped plate body 1 includes an upper lip induction section 1-1 for covering the upper teeth part and a lower lip induction section 1-2 for covering the lower teeth part and supporting the lower lip, a lip line 2 facing the lip direction and used to fill 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, and the upper part of the lower lip induction section 1-2 is an incisor cap 3 protruding toward the upper front teeth and against the incisor end of the upper front teeth.
[0043] The technical solution of this embodiment is to realize the training of the lip muscles and the correction of the upper and lower front teeth through the effects of the lip line 2 and the incisor cap 3 and the synergistic effect between the two. The lip line 2 on the arc 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 a directional pressure, so that the upper and lower lips close, grow, and restore the proper shape and lip muscle tension on the smooth base surface. The incisor cap 3 is semi-wrapped against the incisor 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 lip muscles contract, the synergistic effect of the lip line 2 and the incisor cap 3 can generate the retraction and pressing force of the upper front teeth. In addition, the arc-shaped upper lip induction section 1-1 and lower lip induction section 1-2 are more in line with the space range between the dentition and the lips and cheeks, which is conducive to the formation of normal lip wrapping.
[0044] 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, which are respectively used to avoid the left cheek frenulum of the oral cavity, the middle lip frenulum of the oral cavity, and the right cheek frenulum of the oral cavity.
