Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a lingual dental brace. Background Art

[0002] With the increase and popularization of market demand for orthodontic treatment, the number of clinical applications of self-ligating brackets and invisible braces (bracketless orthodontics) is increasing year by year.

[0003] Self-ligating brackets have become the mainstream product in the fixed orthodontic market due to their simple and convenient operation, short chairside working time, fast tooth movement, high efficiency of alignment and leveling, patient comfort, and easy oral hygiene. However, for many adult patients, they hope to correct their teeth without letting others know, so they choose bracketless braces, which are invisible braces designed and manufactured through digital technology.

[0004] Invisible braces are designed for each patient through a dedicated software system, and then made using modern 3D printing and lamination technology. The thin transparent film is the key material of invisible braces, which has a certain elasticity and toughness. However, due to the limitations of invisible braces in terms of correction force, many cases require preliminary expansion of the dentition, treatment of ectopic teeth, alignment or leveling, etc. before wearing invisible braces.

[0005] The lingual brackets for fixed orthodontics currently on the market have large grooves, with a minimum of 0.018 inches and usually 0.022 inches. On the other hand, they are designed with ligature wings on the jaw and gingival sides. They are not suitable for clinical operations that only use filament arches and do not require ligatures, nor are they suitable for direct lingual bonding. In addition, patients who choose invisible braces have high requirements for experience, and lingual braces that are too large are definitely not easy to accept. Summary of the invention

[0006] In order to solve the problems in the prior art that the existing lingual braces require preliminary expansion of the dentition and treatment of ectopic teeth before formally wearing invisible braces, the process is cumbersome, and the existing lingual braces are large in size, low in wearing comfort, and complicated in installation process, the present application provides a lingual dental brace.

[0007] A lingual dental brace provided in the present application adopts the following technical solution: a lingual dental brace, comprising a base plate, a support body is arranged on one side surface of the base plate, a groove is opened in the middle of the support body along the axial direction, a cover plate is arranged above the support body, the cover plate is slidably connected to the support body, the cover plate closes or detaches from the groove by sliding, and the cover plate and the upper surface of the support body are arranged as arc surfaces.

[0008] By adopting the above technical solution, the appearance of the support body is arc-shaped, so that the overall appearance of the lingual support body is low and compact, which has little effect on the patient's foreign body sensation in the mouth, while ensuring oral hygiene.

[0009] Optionally, a surface on one side of the bottom plate away from the support body is inwardly concave and has a plurality of protrusions evenly spaced in the middle.

[0010] By adopting the above technical solution, when installing the corrector, the orthodontic adhesive is coated on the side surface of the base plate away from the bracket body, and the orthodontic adhesive fills the gaps between the protrusions, thereby improving the adhesion strength between the corrector and the teeth.

[0011] Optionally, an adhesive overflow groove is provided on the edge of the bottom plate.

[0012] By adopting the above technical solution, when applying orthodontic adhesive, excess adhesive can be squeezed out of this overflow groove to avoid excessive adhesive causing the base plate to be too high. At the same time, when correcting, the corrector is subjected to the traction force of the round wire, and the base plate will be deformed. By providing an adhesive overflow groove, the base plate has space for deformation and the stress in the base plate can be eliminated.

[0013] Optionally, reinforcing ribs are provided on the bottom plate surface corresponding to both ends of the groove.

[0014] By adopting the above technical solution, the round wire applies force to the side wall of the groove during use of the corrector, and the strength of the groove is improved by providing reinforcing ribs to prevent the bracket from being deformed under the pulling force of the round wire.

[0015] Optionally, a slide groove is opened in the middle of the upper part of the support body, the cover plate is slidably arranged inside the slide groove, and extension parts extend outwardly on both sides of the cover plate, and the extension parts are clamped inside the side walls on both sides of the slide groove.

[0016] By adopting the above technical solution, the cover plate is connected to the slide groove through the extension part so that the cover plate can slide back and forth inside the slide groove to achieve opening and closing. At the same time, the extension part limits the cover plate radially to prevent the cover plate from falling out of the slide groove.

[0017] Optionally, the groove and the bottom plate are arranged to be inclined downward at a set angle, and a side surface of the inside of the groove close to the bottom plate is arranged to be an arc-shaped surface.

[0018] By adopting the above technical solution, the groove and the bottom plate are set at a downward tilt angle to better fix the round wire, and the bottom surface of the groove is set as an arc surface to fit the surface of the round wire.

[0019] Optionally, the groove width and depth are the same, both of which are 0.3 to 0.5 mm.

[0020] By adopting the above technical solution, the groove width and depth are the same, both of which are 0.3-0.5 mm, so as to be suitable for small-sized round wires of different sizes and models.

[0021] Optionally, a mounting hole is provided in the middle of the support body, a lock core is inserted into the mounting hole, a groove is provided in the middle of the upper end of the lock core, a gourd-shaped slot is provided in the middle of the bottom surface of the cover plate, and the upper end of the lock core extends into the slot.

[0022] By adopting the above technical solution, when the cover is opened, the lock core is located at the end of the slot away from the groove; when the cover moves along the slide groove, the lock core is fixed and the slot moves with the cover; when the lock core and the slot move relative to each other to the middle of the slot, the middle of the slot is narrower and squeezes the upper end of the lock core inward; when the slot is completely closed, the lock core enters the other end of the slot; the lock core is limited by the narrow middle of the slot; the cover is locked through the elastic protrusions on both sides of the groove on the lock core combined with the gourd-shaped slot on the cover, ensuring that the cover is neither too loose nor too tight.

[0023] Optionally, an inwardly recessed pull groove is provided on the edge of the groove on the support body.

[0024] By adopting the above technical solution, the shifting groove is provided to facilitate the operator to shift the cover plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. In this application, under the premise of ensuring invisible correction, only nickel-titanium fine round wire is used to ensure the miniaturization of the working groove of the lingual bracket. By removing the ligature wing design, the bracket has an arc shape, so that the overall appearance of the lingual bracket is low and small, which has little effect on the patient's foreign body sensation in the mouth, while ensuring oral hygiene; 2. In the present application, convex points are arranged on one side of the base plate. When the brace is installed, the orthodontic adhesive is applied to the surface of the base plate away from the bracket. The orthodontic adhesive fills the gaps between the convex points, thereby improving the strength of the adhesion between the brace and the teeth and improving the use effect of the brace; 3. In the present application, a knob is provided on the cover plate, and a snap-fitting portion which cooperates with the groove on the lock core is provided at the lower end of the knob. When the cover plate is opened, the lock core is located at the end of the snap-fitting slot away from the groove. When the cover plate moves along the slide groove, the lock core is fixed, and the snap-fitting slot moves with the cover plate. When the lock core moves to the middle of the snap-fitting slot, the middle of the snap-fitting slot is narrower and squeezes the upper end of the lock core inward. When the snap-fitting slot is completely closed, the lock core enters the other end of the snap-fitting slot. Since the middle of the snap-fitting slot is narrower, the lock core is limited, thereby locking the cover plate, avoiding the cover plate from opening during use, and improving the use effect of the corrector.

[0037] The following is combined with Figure 1-8 This application is described in further detail.

[0038] Embodiment 1: This embodiment discloses a lingual dental brace.

[0039] Reference Figure 1 A lingual dental orthodontic appliance comprises a base plate 1, a support body 2 is arranged in the middle of one side surface of the base plate 1, the support body 2 is in an arc shape, a groove 21 is opened in the middle of the support body 2, both ends of the groove 21 pass through the support body 2, the groove 21 is arranged to be inclined downward in a direction perpendicular to the base plate 1, the width and depth of the groove 21 are the same, both are 0.3-0.5 mm, the bottom surface of the groove 21 is arranged to be a straight surface or an arc surface, a cover plate 3 is arranged above the support body 2, the cover plate 3 slides back and forth along the length direction of the support body 2, the cover plate 3 slides to the top of the groove 21 to close the groove 21, and the edge of the groove 21 on one side away from the cover plate 3 is recessed inward to form a shifting groove 24 to facilitate the shifting of the cover plate 3.

[0040] Reference Figure 2 and Figure 3 , extensions 31 extend outwardly on both sides of the cover plate 3, a slide groove 22 is opened on the top of the support body 2, the cover plate 3 is slidably arranged inside the slide groove 22 through the extensions 31 on both sides, and grooves for accommodating the extensions 31 are formed on the side walls on both sides of the slide groove 22. A card slot 32 is arranged in the middle of the bottom surface of the cover plate 3, and the card slot 32 is gourd-shaped with a narrow middle and round sides.

[0041] Reference Figure 4 and Figure 5A mounting hole 23 is provided in the middle of the slide groove 22 on the bracket 2. The surface of the side of the base plate 1 away from the bracket 2 is recessed inward, and convex points 11 are evenly spaced in the middle. When installing the corrector, the orthodontic adhesive is coated on the side of the base plate 1 away from the bracket 2. The orthodontic adhesive fills the gaps between the convex points 11, which improves the strength of the adhesion between the corrector and the teeth. A reinforcing rib 13 is provided on the surface of the base plate 1 corresponding to the groove 21. During the use of the corrector, the round wire applies force to the side wall of the groove 21. The strength of the groove 21 is improved by setting the reinforcing rib 13 to prevent the bracket 2 from being deformed under the tension of the round wire. An adhesive overflow groove 12 is provided at the edge of the base plate 1. When correcting, the corrector is subjected to the traction of the round wire, and the bottom 1 will be deformed. By setting the adhesive overflow groove 12, the base plate 1 has a deformation space to eliminate the stress in the base plate 1.

[0042] Reference Figure 6 and Figure 7 The mounting hole 23 on the support body 2 is provided with a lock core 4 inserted therein. The lock core 4 includes a lock core body 41. A groove 42 is provided in the middle of the upper end of the lock core body 41. The groove 42 divides the upper end of the lock core body 41 into two convex parts. The upper end of the lock core body 41 extends to the inside of the card slot 32 on the bottom surface of the cover plate 3. When the cover plate 3 is opened, the lock core 4 is located at the end of the card slot 32 away from the groove 21. When the cover plate 3 moves along the slide groove, the lock core 4 is fixed, and the card slot 32 moves with the cover plate 3. When the lock core 4 moves to the middle of the card slot 32, the card slot 32 is narrow in the middle, which squeezes the convex part of the upper end of the lock core 4 inward. When the card slot 32 is completely closed, the lock core 4 enters the other end of the card slot 32. Since the card slot 32 is narrow in the middle, the lock core 4 is limited to achieve locking of the cover plate.

[0043] The implementation principle of a lingual dental brace in the present embodiment is: when performing tooth correction, orthodontic adhesive is coated on the bottom surface of the base plate 1, and the base plate 1 is bonded to the lingual side of the tooth through the orthodontic adhesive. After the orthodontic adhesive is completely cured, the round wire is embedded in the groove 21 on the bracket 2 in sequence, and then the cover plate 3 is moved downward so that the cover plate 3 closes the groove 21. The round wire is closed in the groove by the cover plate 3, and the severely malpositioned teeth or severely misaligned dentition are gradually aligned and leveled through the elasticity of the round wire.

[0044] Embodiment 2: Reference Figure 8 The difference between this embodiment and the first embodiment is that in this embodiment, the base plate 1 is set to be arc-shaped to be suitable for the teeth inside the oral cavity. At the same time, the curvature of the base plate 1 can be customized according to the tooth shape of the tooth to be installed, thereby improving the fit between the corrector and the tooth installation, thereby improving the correction effect.

[0045] To sum up, under the premise of ensuring invisible orthodontics, the present application only uses nickel-titanium fine round wire to ensure the miniaturization of the working groove of the lingual bracket, and then by removing the design of the ligature wing, the appearance of the bracket is arc-shaped, so that the overall shape of the lingual bracket is low and compact, which has little effect on the patient's foreign body sensation in the mouth, while ensuring oral hygiene; in the present application, convex points are set on one side of the base plate, and when the brace is installed, the orthodontic adhesive is coated on the side of the base plate away from the bracket body, and the orthodontic adhesive fills the gaps between the convex points, thereby improving the strength of the adhesion between the brace and the teeth and improving the brace. The use effect of; In the present application, a knob is arranged on the cover plate, and a clamping part matching with the groove on the lock core is arranged at the lower end of the knob. When the cover plate is opened, the lock core is located at the end of the clamping groove away from the groove. When the cover plate moves along the slide groove, the lock core is fixed, and the clamping groove moves with the cover plate. When the lock core moves to the middle of the clamping groove, the middle of the clamping groove is narrow, which squeezes the upper end of the lock core inward. When the clamping groove is completely closed, the lock core enters the other end of the clamping groove. Since the middle of the clamping groove is narrow, the lock core is limited, and the cover plate is locked, which avoids the cover plate from opening during use and improves the use effect of the corrector. Therefore, the present application effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0046] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present application shall still be included in the protection scope of the present application.
