Description

Technical Field

[0001] The present invention relates to a dental instrument, in particular to an oral medical instrument used in oral medicine teaching practice and orthodontic treatment. Background Art

[0002] In orthodontic treatment, invisible orthodontics are becoming more and more well-known to the public, and have a huge orthodontic market. In recent years, invisible orthodontics have become a new trend in the orthodontic industry and are gradually gaining popularity in the domestic market.

[0003] In invisible orthodontics, lingual buckles (such as Figure 1 The use of lingual buckles (as shown in the figure) is relatively common. They contain round protrusions (button-shaped) and a round rough base plate. The base plate is fixed to the teeth by adhesive. The round protrusion device is used to assist in the treatment of tooth misalignment. For teeth with skewed positions, such as locked teeth and twisted teeth, corrective force is applied to promote the teeth to return to their normal position. Or, it can be used as a loading point for traction force to assist elastic traction, such as intra-maxillary or inter-maxillary traction, and play an important role in correcting the occlusal relationship of the dentition. However, due to individual differences and the complexity of malocclusion treatment, the position of force application needs to be selected according to clinical practice. Traditional lingual buckles are difficult to exert biomechanical effects in a personalized way, resulting in poor treatment results.

[0004] For this reason, people have developed a free traction question mark hook (such as Figure 2 (as shown in the figure), the base plate at one end is fixed to the tooth surface by adhesive, and the other end has a long arm hook shaped like a "question mark", which extends the force application point toward the gums of the teeth. By changing the loading site of the orthodontic force, different tooth movements can be achieved to meet clinical needs. Therefore, the emergence of free traction question mark hooks can make up for the shortcomings of traditional lingual buckles and has advantages in controlling the axial inclination of teeth, especially in tooth extraction cases. However, in actual operation, free traction question mark hooks still have many problems, mainly manifested in: ① It is easy to touch the gums, causing discomfort to patients; ② For cases where two different types of traction forces need to be applied to a certain tooth position, such as cases where intermaxillary and intramaxillary traction are performed simultaneously, the current design of the question mark hook makes it inconvenient to apply force; ③ As orthodontic treatment progresses, the force application point changes, and the bonded question mark hook may need to be changed to a lingual buckle again. This process requires reprocessing the tooth surface, making the operation cumbersome and causing a certain degree of damage to the tooth surface; ④ The question mark hooks are divided into left and right, which increases the inventory and is relatively inconvenient to use.

[0005] Therefore, in the clinical practice of orthodontics, although the current instruments can solve some problems, they also cause some disadvantages to patients, and more appropriate solutions still need to be explored. Summary of the Invention

[0006] An object of the present invention is to provide a bonding buckle for orthodontics, which improves the flexibility of orthodontic force application points.

[0007] Another object of the present invention is to provide a bonding buckle for oral orthodontics, which combines the functions of a lingual buckle and a long-arm hook of a free traction question mark hook, thereby realizing "one buckle for multiple uses" and meeting various clinical needs.

[0008] Another object of the present invention is to provide a bonding buckle for orthodontics, which reduces the number of tooth surface treatments, helps improve dental health, and reduces the burden on patients (such as time costs).

[0009] Another object of the present invention is to provide a bonding buckle for oral orthodontics, which solves the problem that free traction question mark hooks need to be distinguished between left and right, can significantly reduce inventory space, make clinical operations more convenient, and improve diagnosis and treatment efficiency.

[0010] A bonding buckle for orthodontics, comprising

[0011] A base plate comprising a first surface and a second surface, wherein the first surface is used for connecting to the tooth surface, such as by bonding;

[0012] a lingual button, one end of which is fixed to the second surface;

[0013] The traction component includes a first arm, a second arm, and a traction arm. One end of the first arm is connected to the lingual button, and the other end is connected to the traction arm. One end of the second arm is connected to the lingual button, and the other end is connected to the traction arm. The length of the traction arm is at least twice that of the first arm or the second arm.

[0014] The tractor guide is arranged on the tractor arm, in a counterposition layout with the first arm or the second arm, located at both ends of the tractor arm, including a curved portion, and the opening is used to place the tractor (such as a rubber chain and rubber ring, etc.).

[0015] Along the axial direction of the traction arm, the first arm and the second arm are sandwiched together, and a through hole (such as a "V" shape) is formed at the sandwiching point; thus, the traction component as a whole presents a "Y"-shaped layout, which is convenient for subsequent removal (such as: grinding) of the traction arm and the traction device guide.

[0016] In order to facilitate the bonding and fixing of the base plate to the tooth surface (such as the tongue side of the tooth), a rough portion is provided on the first surface, such as multiple edges, a grid shape, or a frosted shape.

[0017] The lingual button is higher than the second surface, leaving a gap between the traction component (i.e., the force-applying component) and the gums, thereby preventing gum compression. The preferred height is 2.5 mm ± 0.1 mm, such as, but not limited to, 2.4 mm, 2.5 mm, and 2.6 mm.

[0018] The first arm is made of steel wire with a diameter such as but not limited to 0.5mm±0.1mm, such as but not limited to 0.4mm, 0.5mm and 0.6mm.

[0019] The second arm is made of steel wire with a diameter such as but not limited to 0.5mm±0.1mm, such as but not limited to 0.4mm, 0.5mm and 0.6mm.

[0020] The body width of the traction arm is 1.0 mm to 1.2 mm, such as but not limited to 1.0 mm, 1.1 mm and 1.2 mm, etc. Its length is 3 mm to 5 mm, such as but not limited to 3 mm, 4 mm and 5 mm, etc.

[0021] The diameter of the curved portion is 2.0 mm ± 0.2 mm, such as but not limited to 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm and 2.2 mm, etc. The diameter of the curved portion opening is 0.5 mm ± 0.1 mm, such as but not limited to 0.4 mm, 0.5 mm and 0.6 mm, etc.

[0022] The present invention provides a bonding buckle for oral orthodontics. By applying force to a connection point close to a traction arm, the position of the traction arm can be adjusted, thereby achieving flexibility in the orthodontic force application point, preventing pressure on the gums, reducing damage to the tooth surface, simplifying the orthodontic operation, and improving efficiency.

[0023] For example, the traction component realizes the flexibility of the orthodontic force point. After the realization, the traction arm and the traction device guide are removed, so that it can play the role of the currently commonly used lingual buckle, which is more convenient and flexible to use.

[0024] For example: it combines the lingual buckle and the free traction question mark hook, which makes the operation simpler and more efficient, and realizes more powerful functions, which can meet various needs in the orthodontic treatment stage.

[0025] Third, there is no need to distinguish between the left and right sides, which can significantly reduce the inventory space of the equipment, make clinical operations more convenient, and improve diagnosis and treatment efficiency.

[0026] The present invention design comprises a rough bonded bottom plate, a rounded tongue side buckle and an extended long arm traction member. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The embodiments of the present invention are intended only to illustrate the technical solution of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the invention may be modified or replaced with equivalents without departing from the spirit and scope of the technical solution of the present invention, and all such modifications or equivalents should be included in the scope of the claims of the present invention.

[0032] Figure 3 Schematic diagram of an embodiment of the adhesive buckle of the present invention, Figure 4 for Figure 3 A schematic diagram of the adhesive buckle from another angle. Figure 3 and Figure 4 As shown, the adhesive buckle of the present invention includes a base plate 100 , a lingual button 200 , a traction component 300 and a traction device guide 400 .

[0033] The base plate 100 includes a first surface 110 and a second surface 120. In this embodiment, the first surface 110 is circular with a diameter of 4 mm, which is convenient for fixing to the tooth surface through orthodontic adhesive materials. That is, the adhesive is applied between the first surface 110 and the tooth surface (not shown), and the first surface 110 is fixed to the tooth surface by bonding. Adhesives are commonly used materials in the oral cavity, and the most common method is to use ultraviolet light photosensitive adhesives. In order to facilitate the bonding and fixing of the base plate 100 to the tooth surface (such as the tongue side of the tooth), a rough portion 111 is provided on the first surface 110, such as multiple ribs, a grid shape, or a frosted shape. In this embodiment, a waffle shape is adopted to increase the contact area between the first surface 110 and the adhesive, thereby increasing the roughness of the first surface 110.

[0034] A lingual button 200 is fixed on the second surface 120. One end of the lingual button 200 has a diameter of 2 mm and may also be spherical in shape, and is arranged higher than the second surface 120. The height is preferably 2.5 mm ± 0.1 mm, such as but not limited to 2.4 mm, 2.5 mm and 2.6 mm, so that a gap is left between the traction component (i.e., the force-applying component) and the gums, thereby preventing compression of the gums.

[0035] The lingual button 200 and the base plate 100 can also be manufactured in one piece, for example, by molding, 3D printing, and laser processing.

[0036] The traction component 300 includes a first arm 310, a second arm 320, and a traction arm 330. One end of the first arm 310 is connected to the lingual button 200, and the other end is connected to the traction arm 330. One end of the second arm 320 is connected to the lingual button 200, and the other end is connected to the traction arm 330. In this embodiment, the first arm 310 is made of steel wire with a diameter of 0.5 mm. The second arm is also made of steel wire with a diameter of 0.5 mm. By applying force near the traction arm 330 at the connection point, the position of the traction arm 330 can be adjusted, such as towards or away from the gums.

[0037] A recess 340 is also provided on the first arm 310 near the connection with the lingual button 200 to mark the location for removal or grinding of the distraction member 300. A similar arrangement is also provided on the second arm 320. The recess is shaped like a "<" or ">" to facilitate positioning of the needle and grinding of the distraction arm 330.

[0038] Along the axial direction of the traction arm 330, the first arm and the second arm are sandwiched together, forming a cavity (such as a "V" shape) at the sandwiched position; thus, the traction component as a whole presents a "Y"-shaped layout, which is convenient for subsequent removal (such as grinding) of the traction arm and the traction device guide.

[0039] The traction arm 330 is at least twice as long as the first arm 310 or the second arm 320. Its body width is 1.1 mm to 1.2 mm, and its length is 3 mm or 5 mm. A tractor guide 400 is also provided on the traction arm 330, arranged in an aligned arrangement with the first arm 310 or the second arm 320, and located at both ends of the traction arm 330. The tractor guide 400 includes a curved portion (not shown) with a diameter of 2.0 mm and an opening 410 with a diameter of 0.5 mm to facilitate the smooth insertion of traction devices such as rubber chains and rubber bands. Since the opening 410 is located at the bottom end of the curved portion, there is no need to distinguish between left and right sides, thus reducing the storage space for the devices.
