Description

Technical Field

[0001] The invention relates to the field of oral orthodontic correction, and in particular to a bonding positioning device used for oral orthodontics. Background Art

[0002] In current orthodontic treatment, direct bonding is usually used to bond brackets to tooth surfaces. Since the existing direct bonding technology is based on manual bonding based on the doctor's experience, this method is highly dependent on the doctor's bonding skills and naked eye observation. It is labor-intensive, inefficient, has poor repeatability, and is less than ideal in accuracy. Despite this, due to its intuitiveness, it is still widely used in clinical practice by most orthodontists.

[0003] In order to overcome these shortcomings of direct bonding technology, indirect bonding technology has been developed. Indirect bonding technology is to place the bracket in a transfer device and transfer the bracket to the tooth through the transfer device. At present, most of the transfer devices on the market are difficult to remove from the tooth surface by oral orthodontic tools after the bracket is bonded to the tooth surface. The orthodontist needs to manually remove the transfer device from the tooth surface. However, due to the small oral environment, the orthodontist does not have a large operating space to remove the transfer device, which usually takes a lot of time and energy, increasing the work intensity and operation time of the orthodontist, which violates the original intention of indirect bonding to reduce the work intensity of the orthodontist. It also makes the orthodontic experience of orthodontic patients poor, so orthodontists often abandon the indirect bonding technology and use direct bonding technology to bond brackets for orthodontic patients. Summary of the invention

[0004] In view of the defects of the prior art, the object of the present invention is to provide a bonding positioning device which can be accurately positioned and easily disassembled.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A bonding positioning device for orthodontics, the bonding positioning device comprising at least one positioning unit, the positioning unit comprising a tooth positioning structure and a bracket positioning structure connected to each other; the tooth positioning structure is used to abut against the tooth end surface of the tooth, the bracket positioning structure is used to clamp and release the bracket, the bracket positioning structure comprises a first elastic clamping block and a second elastic clamping block arranged on the mesial and distal sides of the corresponding bracket, a gap is formed between the first elastic clamping block and the second elastic clamping block, the gap extends along the gingival tooth direction, and the gap extends to the gingival end of the first elastic clamping block and the second elastic clamping block.

[0007] All currently available bonding and positioning devices adopt a rigid, one-piece clamping structure, while the present invention adopts an elastic clamping and positioning device, and in order to facilitate disassembly, it is divided into two elastic clamping blocks, and a gap is provided between the first elastic clamping block and the second elastic clamping block, so that the first elastic clamping block and the second elastic clamping block can cooperate with each other to clamp the bracket located therebetween, and can stably clamp the bracket; when the bracket needs to be released, when force is applied to remove the bonding and positioning device, the first elastic clamping block and the second elastic clamping block will deform toward the outside of the gap, thereby achieving the release of the bracket.

[0008] In some preferred embodiments, the first elastic clamping block and the second elastic clamping block can prevent the bracket from moving in the mesiodistal direction and in the labiolingual direction.

[0009] In some preferred embodiments, the first elastic clamping block and the second elastic clamping block form an insertion position at the gap, and the insertion position is used for inserting a separation tool.

[0010] By setting the insertion position to facilitate the insertion of the separation tool, the first elastic clamping block and the second elastic clamping block can be relatively separated, which facilitates the release of the bracket clamped between the first elastic clamping block and the second elastic clamping block.

[0011] In some further preferred embodiments, the bracket positioning structure includes a separation block, and the separation block is clamped in the insertion position by the first elastic clamping block and the second elastic clamping block, and the separation block can move along the labial-lingual direction.

[0012] In a further preferred embodiment, the width of the separation block along the lip-tongue direction of the bracket positioning structure gradually increases.

[0013] In some preferred embodiments, the two ends of the first elastic clamping block are respectively a first gripping end and a first clamping end, and the two ends of the second elastic clamping block are respectively a second gripping end and a second clamping end, the first clamping end and the second clamping end cooperate with each other to clamp and release the bracket, a first gap is formed between the first clamping end and the second clamping end, and a second gap is formed between the first gripping end and the second gripping end, and when a force is applied to the first gripping end and the second gripping end to bring them closer together, the first clamping end and the second clamping end move away from each other. By applying a force to the first gripping end and the second gripping end so that the first clamping end and the second clamping end move away from each other, it is convenient for the orthodontist to clamp and release the bracket, thereby improving the efficiency of orthodontic treatment. A tool such as pliers can be used to apply a force to the first gripping end and the second gripping end, which can make the operation more convenient.

[0014] In some further preferred embodiments, the first holding end is connected to the first clamping end via a first connecting segment, the second holding end is connected to the second clamping end via a second connecting segment, the first connecting segment and the second connecting segment intersect in space, and the first holding end and the second holding end are connected to the tooth positioning structure.

[0015] In some other further preferred embodiments, the first holding end is connected to the first clamping end via a first connecting section, the second holding end is connected to the second clamping end via a second connecting section, the first connecting section is parallel to the second connecting section, and the first connecting section and the second connecting section are connected to the tooth positioning structure via a connecting block.

[0016] In some preferred embodiments, the first elastic clamping block includes a first clamping piece, and the second elastic clamping block includes a second clamping piece. The first clamping piece and the second clamping piece are respectively used to clamp the proximal and distal sides of the bracket. The first elastic clamping block also includes a third clamping piece connected to the first clamping piece, and the third clamping piece is used to limit the movement of the bracket along the labial and lingual direction. The gap is formed between the third clamping piece and the second elastic clamping block, and the gap extends along the gingival tooth direction. The gap extends to the gingival end of the first elastic clamping block and the second elastic clamping block. The first clamping piece and the second clamping piece elastically clamp the bracket therebetween, so that the bracket can be firmly clamped between the first clamping piece and the second clamping piece, and the bracket can be prevented from moving along the proximal and distal directions, and the bracket can be accurately clamped and positioned; the third clamping piece can prevent the bracket from moving along the labial and lingual direction, accurately position the bracket, and prevent the bracket from falling off the bracket positioning structure.

[0017] In some further preferred embodiments, the second elastic clamping block also includes a fourth clamping piece connected to the second clamping piece, and the fourth clamping piece is used to limit the movement of the bracket along the labial and lingual direction. The gap is formed between the third clamping piece and the fourth clamping piece, and the gap extends along the gingival tooth direction. The gap extends to the gingival end of the first elastic clamping block and the second elastic clamping block.

[0018] The third clamping piece and the fourth clamping piece can prevent the bracket from moving along the lip and tongue direction, accurately position the bracket, and prevent the bracket from falling off the bracket positioning structure.

[0019] In some further preferred embodiments, the widths of the third clamping piece and the fourth clamping piece gradually increase along the direction from the tooth end to the gingival end of the first elastic clamping block.

[0020] In some preferred embodiments, the bracket positioning structure is provided with a limiting structure, and the limiting structure is used to limit the movement of the bracket along the gingival tooth direction. The limiting structure limits the movement of the bracket along the gingival tooth direction, thereby more accurately accommodating and positioning the bracket in the bracket positioning structure, thereby avoiding inaccurate positioning of the bracket in the bracket positioning structure, resulting in poor indirect bonding effect.

[0021] Furthermore, the limiting structure includes a protrusion, and the protrusion is used to abut against the concave part formed between the main body of the bracket and the bottom plate of the bracket, thereby preventing the bracket from moving along the gingival tooth direction.

[0022] The raised portion abuts against the concave portion between the main body of the bracket and the bottom plate of the bracket, further limiting the position of the bracket and precisely clamping it.

[0023] Furthermore, the limiting structure also includes a recessed portion connected to the raised portion, and the recessed portion matches the main body shape of the bracket.

[0024] The recessed portion matches the main shape of the bracket, and can more accurately and stably clamp and position the bracket, adapt to the shape of the bracket, and prevent the bracket from falling off the positioning unit.

[0025] Furthermore, the limiting structure is connected to the first elastic clamping block and / or the second elastic clamping block. The limiting structure can be a separate structure or a structure integrally formed with the elastic clamping block.

[0026] In some preferred embodiments, the bonding positioning device includes at least one positioning unit, and the positioning unit includes a tooth positioning structure and a bracket positioning structure that are interconnected; the tooth positioning structure is used to abut against the tooth end surface of the tooth, and the bracket positioning structure is used to clamp and release the bracket, and the tooth positioning structure includes a removal piece, and the removal piece is used for a removal tool to hook, clamp or abut.

[0027] Currently, all indirect bonding devices are not provided with a structure that is convenient for doctors to remove the indirect bonding devices. It is difficult to remove the indirect bonding devices using tools, and repeated operations are required. The bonding positioning device in the present invention is provided with a removal piece, which is convenient for the orthodontist to hook, clamp or push the removal piece with the removal tool, and then remove the bonding positioning device from the tooth. The orthodontist can easily and quickly remove the bonding positioning device bonded to the tooth surface without wasting the orthodontist's time and energy, and also improves the patient's treatment comfort.

[0028] Furthermore, the removal piece is used for being hooked or pressed by a hook-shaped removal tool, and the removal piece includes at least one of a recessed structure, a hole-shaped structure, a ring-shaped structure and a slit structure, and the removal piece is arranged on at least one of the labial side, the lingual side, the tooth end face, the gingival end face, the mesial surface and the distal surface of the tooth positioning structure. Currently, the existing bonding positioning devices are mainly removed by the doctor's hands, and the bonding positioning device is not provided with a structure that is convenient for tool operation. Since the bonding positioning device is small and the fingers are relatively large, they will block the doctor's line of sight after being inserted into the oral cavity. It is inconvenient and difficult to operate to use fingers to remove the bonding positioning device. Among the commonly used dental tools, there are many hook-shaped removal tools, such as probes, which are one of the tools that dentists can easily use. Providing a removal piece for the hook-shaped tool can greatly increase the convenience of dentists in removing the bonding positioning device. The directions and positions of the tooth positioning structures for different tooth positions are different for doctors to operate. For example, the lingual side, tooth end, and mesial surface of the tooth positioning structures for posterior teeth such as premolars and molars are convenient locations for operation, while the lingual side, labial side, tooth end, gingival end, mesial surface, and distal surface of the tooth positioning structures for anterior teeth such as incisors, lateral incisors, and canines are convenient locations for operation. The removal piece only needs to be provided with a convenient location for operation, which can facilitate the doctor to disassemble the bonding positioning device.

[0029] Furthermore, the removal piece is used for clamping a clamp-like removal tool, and the removal piece includes at least one of a protruding structure, a hole-like structure, and a ring-like structure, and the removal piece is arranged on at least one of the labial side, lingual side, tooth end surface, gingival end surface, mesial surface, and distal surface of the tooth positioning structure. Common dental tools also include clamp-like removal tools, such as tweezers or pliers, which are one of the tools that dentists can use very conveniently. Providing a removal piece for the clamp-like tool can also greatly increase the convenience of dentists in removing the bonding positioning device.

[0030] Furthermore, the tooth positioning structure also includes a guide member, which is connected to the removal member and is used to guide the end of the removal tool to position the removal member.

[0031] By providing the guide piece, the orthodontist can accurately position the removal tool in the removal piece under the guidance of the guide piece, thereby improving the efficiency and accuracy of removing the bonding positioning device.

[0032] Furthermore, the guide member is at least one of a notch structure and a recessed structure.

[0033] Furthermore, the bonding positioning device comprises at least two positioning units, and two adjacent positioning units are detachably connected.

[0034] Furthermore, the tooth positioning structure comprises a tooth positioning body and a tooth positioning block, an accommodating positioning cavity is formed on the tooth positioning body, and the tooth positioning block is placed in the accommodating positioning cavity.

[0035] Furthermore, the tooth positioning structure includes a tooth positioning body and a tooth positioning block, the tooth positioning body is formed with a receiving positioning cavity, and the tooth positioning block is placed in the receiving positioning cavity. The tooth positioning block and the receiving positioning cavity are arranged so that the tooth positioning block can be personalized according to the patient's tooth shape, while the receiving positioning cavity can be standardized. When orthodontic correction is performed, only the tooth positioning block needs to be personalized, which saves costs and improves production efficiency.

[0036] Beneficial effect: The present invention provides a bonding positioning device for orthodontics, the bonding positioning device comprises at least one positioning unit, the positioning unit comprises a tooth positioning structure and a bracket positioning structure connected to each other; the tooth positioning structure is used to abut against the tooth end surface of the tooth, the bracket positioning structure is used to clamp and release the bracket, the bracket positioning structure comprises a first elastic clamping block and a second elastic clamping block arranged on the mesial and distal sides of the corresponding bracket, a gap is formed between the first elastic clamping block and the second elastic clamping block, the gap extends along the gingival tooth direction, and the gap extends to the The gingival end of the first elastic clamping block and the second elastic clamping block; the existing bonding positioning devices all adopt a rigid, one-piece clamping structure, while the present invention adopts an elastic clamping positioning device, and in order to facilitate disassembly, it is divided into two elastic clamping blocks, and there is a gap between the first elastic clamping block and the second elastic clamping block, so that the first elastic clamping block and the second elastic clamping block can cooperate with each other to stably clamp the bracket; when the bracket needs to be released, when force is applied to remove the bonding positioning device, the first elastic clamping block and the second elastic clamping block will deform toward the outside of the gap, and the bonding positioning device can be easily removed.

[0059] Unless otherwise specified, in the following structural description, the reference system of the mandibular teeth is required to describe the bonding positioning device. Therefore, as used herein, the terms such as labial, lingual, mesial, distal, tooth end surface, gingival end and tooth end used to describe the bonding positioning device are relative to the selected reference system. However, the embodiments of the present invention are not limited to the selected reference system and the terms described, because the bonding positioning device can be used for other teeth and other directions in the oral cavity. For example, the bonding positioning device can also be coupled to the lingual surface of the tooth and fall within the scope of the present invention. Those skilled in the art will realize that when there are changes in the reference system, the descriptive terms used herein may not be directly referenced. However, the embodiments of the present invention are intended to be independent of the position and direction in the oral cavity and the related terms used to describe the embodiments are only to provide clear descriptions of the embodiments in the accompanying drawings. Similarly, the related terms labial, lingual, mesial, distal, tooth end surface, gingival end and tooth end will never limit the present invention to a specific position or direction.

[0060] It should be noted that the related terms labial, lingual, mesial, distal, tooth end surface, gingival end and tooth end are industry terms for orthodontic treatment. Figure 1, taking a tooth in the right area of ​​the mandible as an example, the surface of the tooth can be roughly divided into six faces. The face of the tooth that occludes with the maxillary teeth is the tooth end face or tooth surface, and the end where the tooth surface is located is called the tooth end; the face of the tooth connected to its attached gingival tissue is the gingival face, and the end where the gingival face is located is the gingival end; the tooth surface is opposite to the gingiva, and the direction formed by the tooth surface and the gingiva is also called the gingival direction. The face of the tooth facing the lips is the labial side face, and the side where the labial side face is located is called the labial side; the face of the tooth facing the tongue is the lingual side face, and the side where the lingual side face is located is called the lingual side. The labial side face and the lingual side face are opposite, and the direction formed by the labial side face and the lingual side face is also called the labiolingual direction. The two faces of the tooth that contact the adjacent teeth are the mesial face and the distal face, respectively. The difference between them is the distance from the middle part. The mesial face is close to the central incisor, and the distal face is far away from the central incisor. The direction formed by the two is also called the mesiodistal direction, or the mesiodistal direction.

[0061] Embodiment 1:

[0062] See also Figure 1-12 and Fig. 20 A bonding positioning device 10 includes at least one positioning unit 11, the positioning unit 12 includes a tooth positioning structure 13 and a bracket positioning structure 12 connected to each other, the tooth positioning structure 12 is used to abut against the tooth end surface of the tooth, and the bracket positioning structure 12 is used to clamp the bracket 27 and release the bracket 27 on the tooth surface.

[0063] The tooth positioning structure 13 includes a removal piece, which is used for being hooked, clamped or pressed by a removal tool. The removal piece is located on at least one of the labial side, lingual side, tooth end face and gum end face of the tooth positioning structure or on two or more sides at the same time.

[0064] The removal piece has a insertion hole suitable for removal tools (for example, probes, tweezers). The removal tool applies force to the removal piece to move the tooth positioning structure 13, thereby driving the positioning unit 11 to move, making it easier to remove the positioning unit 11 from the tooth surface and facilitating the orthodontist's removal of the positioning unit 11.

[0065] The structure of the removal piece can be one of a concave structure, a convex structure, a hole structure and a ring structure, or a combination of any two or more thereof.

[0066] The tooth positioning structure 13 further comprises a guide member 32 connected to the removal member, and the guide member 32 is used to guide the removal tool into the removal member.

[0067] The guide member 32 is at least one of a notch structure and a recessed structure.

[0068] Preferably, the guide member 32 may be an inclined surface or a curved surface structure.

[0069] The preferred solution of the removal member or the combination of the removal member and the guide member 32 is as follows.

[0070] Preferred Option 1, see Figure 3 The removal piece of the preferred solution is a removal piece 42, which is arranged on the labial side or the lingual side of the tooth positioning structure 13. The removal piece 42 is a combination of a convex structure and a concave structure. The convex structure is arranged on the labial side or the lingual side of the tooth positioning structure 13, and the concave structure is arranged on the gingival end surface of the convex structure. The concave structure is preferably a hemispherical concave. The hemispherical concave of the removal piece 42 is convenient for the removal of removal tools such as a probe, so that the positioning unit 11 is easily removed from the tooth surface. In some other embodiments, the removal piece may also include a convex structure or a concave structure.

[0071] See also Figure 3 At the same time, the removal piece 42 is arranged on the gingival end surface of the lip end of the tooth positioning structure 11. This is to facilitate when the positioning unit 11 is installed on the incisors, lateral incisors, canines and other teeth. The incisors, lateral incisors, canines and other teeth are located outside the oral cavity, and the cheeks will not resist the insertion of the removal tools. It is convenient for the orthodontist to directly connect the removal piece 42 from the front through the removal tools such as probes to remove the positioning unit 11 from the teeth.

[0072] Preferably, when the removal piece 42 is disposed on the lingual side of the tooth positioning structure 13, it is convenient for the removal tool to be inserted into the removal piece 42 when the positioning unit 11 is installed on the posterior teeth such as premolars and molars, so that the orthodontist can directly hook the removal piece 42 with the removal tool such as a probe or tweezers. When the removal piece 42 is disposed on the labial side or buccal side of the tooth positioning structure 13, the buccal side of the posterior teeth such as premolars and molars has a cheek, which will block the orthodontist's line of sight, and the cheek will prevent the removal tool from being inserted into the labial side or buccal side of the tooth positioning structure 13, which is not conducive to the orthodontist's operation.

[0073] Preferably, the tooth positioning structure 13 is also provided with a guide member 32, and the guide member 32 is arranged on the protruding structure of the removal member 42. The guide member 32 is a notch structure, which is convenient for the orthodontist to observe, so that the orthodontist can use tools to accurately and quickly find the guide member 32, and then locate the removal member 42. A transition slope is provided at the connection between the guide member 32 and the removal member 42 to guide the removal structure such as the probe to enter the removal member 42, which is convenient for the orthodontist to operate.

[0074] Preferred Option 2, see Figure 4 The removal member of the preferred solution is the second removal member 43, which is arranged on the tooth end surface of the tooth positioning structure 13. The second removal member 43 is a protruding structure, and the protrusion is preferably a boss. The protruding structure of the second removal member 43 is convenient for clamping with a removal tool such as pliers or tweezers, so that the positioning unit 11 can be easily and conveniently removed from the tooth surface.

[0075] When the positioning unit 11 is installed on the posterior teeth such as premolars and molars, the lip side cannot be operated due to the resistance of the cheek. The removal piece 43 is set on the tooth end surface of the tooth positioning structure 13, which can facilitate the orthodontist to directly clamp the removal piece 43 with a probe or tweezers to remove the positioning unit 11 from the tooth.

[0076] Preferred Option 3, see Figure 5 The removal piece of the preferred solution is the removal piece 3 44, which is arranged on the tooth end surface of the tooth positioning structure 13. The removal piece 3 44 is a combination of a protruding structure and a hole-like structure, and the hole extends along the labial and lingual direction. The hole is preferably a through hole. The protruding structure of the removal piece 3 44 has a hole, so that it is convenient for a probe or tweezers or other removal tools to extend into the hole, so that the orthodontist can directly connect the removal piece 3 44 with the removal tool such as the probe to remove the positioning unit 11 from the tooth; the protruding structure of the removal piece 3 44 is also convenient for tweezers or pliers to clamp, and then the positioning unit 11 is directly removed from the tooth surface by clamping the protruding structure of the removal piece 3 44 with tweezers.

[0077] Preferred Option 4, see Figure 6 The removal piece of the preferred embodiment is a removal piece 45, which includes a protruding structure provided on the labial side or the lingual side of the tooth positioning structure 13 and a hole provided on the protruding structure and extending in the gingival direction. When the positioning unit 11 is installed on the front teeth such as the incisors, lateral incisors, and canines, the incisors, lateral incisors, and canines are located outside the oral cavity, and the removal piece 45 is provided on the labial side of the tooth positioning structure 13. When the cheek does not resist the insertion of the removal tool, it is convenient for the orthodontist to directly hook the removal piece 45 from the front through a hook-shaped removal tool such as a probe and remove the positioning unit 11 from the tooth. When the positioning unit 11 is installed on the posterior teeth such as the premolars and molars, the removal piece 45 is provided on the lingual side of the tooth positioning structure 13 to avoid the obstruction of the cheek, which can facilitate the orthodontist to directly hook the removal piece 45 through a hook-shaped removal tool such as a probe.

[0078] Preferred Option 5, see Figure 7 The removal piece of the preferred embodiment is the removal piece 5 46, which is a hole provided on the tooth positioning structure 13, and the hole can be located on the lingual side or labial side of the tooth positioning structure 13. The hole-shaped structure of the removal piece 5 46 allows hook-shaped removal tools such as probes to extend into the hole, directly hook the removal piece 5 46, and remove the positioning unit 11 from the tooth. Similarly, the removal piece can be located on the lingual side or labial side according to the tooth position to which the positioning unit 11 is bonded. Moreover, the removal piece 46 disposed on the mesial surface, distal surface, tooth end surface, and gingival end surface of the tooth positioning structure 13 can also be hooked by the removal tool, and then the positioning unit 11 can be removed.

[0079] Preferred Option 6, see Figure 8 The removal member of the preferred embodiment is a removal member 6 47, which is arranged on the gingival end surface of the tooth positioning structure 13. The removal member 6 47 is an annular structure, and the preferred convex ring can be rectangular or circular. The hook-shaped removal tool can be inserted into the removal member 6 47 to directly remove the positioning unit 11 from the tooth.

[0080] Preferably, in addition to the preferred solutions 1 to 6 of the above removal member, other structures such as slit structures can also meet the needs and can be used as the removal member, and any part of the preferred solutions 1 to 6 of the removal member can be arbitrarily combined to achieve the purpose of convenient removal of the positioning unit 11.

[0081] The bracket positioning structure 12 is used to clamp the bracket 27 and release the bracket 27 on the tooth surface. The bracket positioning structure 12 can limit the movement of the bracket 27 located therein from the mesiodistal direction and the labial-lingual direction.

[0082] The bracket positioning structure 12 includes a first elastic clamping block 14 and a second elastic clamping block 15 for correspondingly limiting the movement of the bracket 27 in the mesiodistal direction, the labiolingual direction and the gingival direction. The first elastic clamping block 14 and the second elastic clamping block 15 correspond to the mesiodistal sides of the bracket 27. A gap 25 is formed between the first elastic clamping block 14 and the second elastic clamping block 15, and the gap 25 extends along the gingival tooth direction. The first elastic clamping block 14 and the second elastic clamping block 15 can limit the movement of the bracket 27 in the mesiodistal direction and the labiolingual direction, that is, the accurate positioning of the bracket 27 in the mesiodistal direction and the labiolingual direction can be achieved. The tooth end of the first elastic clamping block 14 is connected to the gingival end of the tooth positioning structure 13, and the tooth end of the second elastic clamping block 15 is connected to the gingival end of the tooth positioning structure 13. The bracket positioning structure 12 is also provided with a limiting structure, and the limiting structure is used to limit the movement of the bracket along the gingival tooth direction. After the bracket 27 is placed in the accommodation space, the bracket is pressed against the limiting structure to achieve accurate positioning of the bracket 27 in the gingival tooth direction.

[0083] The first elastic clamping block 14 has two ends in the gum direction, namely, a tooth end and a gum end, and the second elastic clamping block 15 has two ends in the gum direction, namely, a tooth end and a gum end. The gap 25 extends to the gum ends of the first elastic clamping block 14 and the second elastic clamping block 15 .

[0084] When the bracket needs to be clamped, force can be applied to put the bracket 27 between the first elastic clamping block 14 and the second elastic clamping block 15. At present, the existing bonding positioning devices all clamp the bracket rigidly, and there are problems with the positioning accuracy, stability and disassembly of the clamping. The clamping block is set as an elastic clamping block, and a gap 25 is left between the two elastic clamping blocks, which can not only maintain the stability and accuracy of the clamping, but also make the bracket easy to remove from the bonding positioning device. In a preferred embodiment, the width of the accommodating space formed between the first elastic clamping block 14 and the second elastic clamping block 15 is less than or equal to the width of the bracket 27. Since the first elastic clamping block 14 and the second elastic clamping block 15 are elastic, after the bracket is placed in the accommodating space formed between the first elastic clamping block 14 and the second elastic clamping block 15, it can be firmly clamped by the first elastic clamping block 14 and the second elastic clamping block 15 and will not fall.

[0085] Preferably, the first elastic clamping block 14 and the second elastic clamping block 15 may not be directly connected, but may be indirectly connected via the tooth positioning structure 13, so that the first elastic clamping block 14 and the second elastic clamping block 15 can be better unfolded and separated.

[0086] In this embodiment, the first elastic clamping block 14 includes a first clamping piece 16 and a third clamping piece 22 connected to each other, and the second elastic clamping block 15 includes a second clamping piece 17 and a fourth clamping piece 23 connected to each other. The first clamping piece 16 and the second clamping piece 17 are used to limit the movement of the bracket 27 in the mesiodistal direction, apply elastic clamping force to the bracket 27, and clamp the mesiodistal and mesiodistal sides of the bracket 27. The third clamping piece 22 and the fourth clamping piece 23 are used to limit the movement of the bracket 27 in the labiolingual direction, and prevent the bracket 27 from falling off the bracket positioning structure 12 from the labial direction. A gap 25 is formed between the third clamping piece 22 and the fourth clamping piece 23, and the gap 25 extends along the gingival tooth direction, and the gap 25 extends to the gingival end and tooth end of the third clamping piece 22 and the fourth clamping piece 23.

[0087] The bracket positioning structure 12 also includes a limiting structure, which can limit the movement of the bracket 27 located in the bracket positioning structure 12 along the gingival direction. The limiting structure is adapted to the structure of the tooth end of the bracket 27. In this embodiment, the limiting structure includes a connected recessed portion and a raised portion, wherein the recessed portion is used to accommodate the outer shape structure of the tooth end of the bracket 27, and the raised portion is used to abut against the concave portion formed between the main body 29 of the bracket 27 and the bottom plate 30 of the bracket 27, and the recessed portion and the raised portion interact with each other, so that the bracket 27 can be accurately fixed in the bracket positioning structure 12.

[0088] In this embodiment, the limiting structure includes a first limiting structure and a second limiting structure connected to the first elastic clamping block 14 and the second elastic clamping block 15 respectively, wherein the limiting structure located at the first elastic clamping block 14 is the first limiting structure, and the limiting structure located at the second elastic clamping block 15 is the second limiting structure. The first limiting structure is used to abut the left half of the tooth end of the bracket 27, and the second limiting structure acts on the right half of the tooth end of the bracket 27. The first limiting structure includes a first recessed portion 20 and a first protruding portion 18, and the second limiting structure includes a second recessed portion 21 and a second protruding portion 19.

[0089] The first recessed portion 20 and the second recessed portion 21 accommodate the outer shape structure of the tooth end of the bracket 27, so that the outer shape structure of the tooth end of the bracket 27 can be double-limited and accurately and firmly accommodated in the bracket positioning structure 12. The first raised portion 18 and the second raised portion 19 abut against the inner concave portion formed between the main body 29 of the bracket 27 and the bottom plate 30 of the bracket 27, so that the inner concave portion formed between the main body 29 of the bracket 27 and the bottom plate 30 of the bracket 27 is double-limited and accurately and firmly accommodated in the bracket positioning structure 12.

[0090] In other embodiments, the limiting structure may be a limiting structure formed by connecting the first limiting structure and the second limiting structure, or may only include any one of the first limiting structure and the second limiting structure.

[0091] Preferably, the first elastic clamping block 14 and the second elastic clamping block 15 are mirror-symmetrical and interact with each other to apply an elastic clamping force to the bracket 27 located between the first elastic clamping block 14 and the second elastic clamping block 15 .

[0092] The tooth end surface of the tooth positioning structure 13 of the positioning unit 11 has a tooth position mark, and the labial side surface of the bracket positioning structure 12 has an axis tilt mark. The establishment of the tooth position mark and the axis tilt mark facilitates the orthodontist to accurately identify the tooth position acted on by the bonding positioning device 10, and the establishment of the axis tilt mark further assists the precise positioning of the bonding positioning device 10.

[0093] Preferably, the gap 25 of the present invention can be used as an axial inclination marker to facilitate the orthodontist's precise bonding positioning.

[0094] The bonding positioning device 10 comprises at least one positioning unit 11. At least two positioning units 11 are detachably connected to each other. At least two positioning units 11 are connected to each other via a connecting strip 26.

[0095] Preferably, the connecting strip 26 between at least two positioning units 11 can be one or more, distributed on both sides of the lip and tongue of the positioning unit 11. The connecting strip 26 can be a cylinder, a quasi-cylindrical cylinder, an elliptical cylinder, a quasi-elliptical cylinder, a prism, a quasi-prism, etc., which are easy to destroy. The setting of the connecting strip 26 allows the bonding positioning device 10 to be broken when the corresponding positioning unit 11 is required to be corrected or when the bonding bracket 27 is completed, so that the positioning units 11 can be removed from the bonding positioning device 10 one by one.

[0096] Preferably, the tooth positioning structure 13 includes a tooth positioning body and a tooth positioning block, wherein a positioning cavity is formed on the tooth positioning body, and the tooth positioning block is placed in the positioning cavity. Currently, most tooth positioning structures on the market are in one piece and are customized according to the tooth end faces of the patient's teeth. In order to improve production efficiency, the tooth positioning structure is divided into a tooth positioning body that can be mass-produced and a customized tooth positioning block, which can speed up the production efficiency of the bonding positioning device and reduce the manufacturing difficulty.

[0097] Embodiment 2:

[0098] See also Fig.13 This embodiment provides a bonding positioning device for orthodontics, and its structure is basically the same as that of the bonding positioning device in Embodiment 1, except that: the width of the third clamping piece 22 gradually increases along the tooth end toward the gingival end, and the width of the fourth clamping piece 23 gradually increases along the tooth end toward the gingival end. The change in the width of the third clamping piece 22 and the change in the width of the fourth clamping piece 23 facilitate the convergence of the elastic clamping force of the third clamping piece 22 and the fourth clamping piece 23, so that the first elastic clamping block 14 and the second elastic clamping block 15 can firmly clamp the bracket 27.

[0099] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0100] Embodiment three:

[0101] See also Fig.14 This embodiment provides a bonding positioning device for orthodontics, and its structure is basically the same as that of the bonding positioning device in Example 1, except that the gap 25 between the first elastic clamping block 14 and the second elastic clamping block 15 of the positioning unit 11 extends from the gingival end of both to the tooth end of both and extends through the tooth positioning structure 13. It is convenient to separate and unfold the first elastic clamping block 14 and the second elastic clamping block 15, and to install or remove the bracket 27 in the positioning unit 11.

[0102] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0103] Embodiment 4:

[0104] See also Fig.15 , this embodiment provides a bonding positioning device for orthodontics, and its structure is basically the same as the bonding positioning device in Example 1, and the specific difference is that: the first elastic clamping block 14 includes a first clamping piece 16 and a third clamping piece 22, and the second elastic clamping block 15 includes a second clamping piece 17, but does not have a fourth clamping piece 23. The width of the third clamping piece 22 in the mesiodistal direction extends close to the second clamping piece 17, and the third clamping piece 22 is used to limit the movement of the bracket 27 in the labial and lingual direction, and prevent the bracket 27 from falling from the bracket positioning structure 12 from the labial direction. A single third clamping piece 22 can prevent the bracket 27 located on the positioning unit 11 from falling, and the structure is simple and easy to manufacture. A gap 25 is formed between the third clamping piece 22 and the second clamping piece 17, and the gap 25 extends in the gingival and tooth direction. The gap 25 extends to the gingival end and tooth end of the third clamping piece 22 and the second clamping piece 17.

[0105] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0106] Embodiment five:

[0107] See also Fig.16 The present embodiment provides a bonding positioning device 10 for orthodontics, and its structure is basically the same as the bonding positioning device 10 in the first embodiment, and the specific difference is that: there is a gap 25 between the first elastic clamping block 14 and the second elastic clamping block 15, and a part of the gap 25 forms an insertion position 33, and the insertion position 33 can be used for the insertion of separation tools such as probes or tweezers.

[0108] Preferably, the separation tool can be a separation block 34, the width of which gradually increases along the labial and lingual direction of the bracket positioning structure 12, and the separation block 34 can be inserted into the insertion position 33 along the labial and lingual direction, and with the insertion of the separation block 34, the first elastic clamping block 14 and the second elastic clamping block 15 can be forced to separate. By providing the separation block 34, the orthodontist can separate the first elastic clamping block 14 from the second elastic clamping block 15 by inserting the separation block 34 into the insertion position 33, and then enter to facilitate the removal of the bracket 27 clamped between the first elastic clamping block 14 and the second elastic clamping block 15 without spending a lot of time and effort.

[0109] Preferably, the separation block 34 may be in a wedge shape or a shuttle shape.

[0110] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0111] Embodiment six:

[0112] See also Fig.17 and Fig.18 The present embodiment provides a bonding positioning device 10 for orthodontics, and its structure is basically the same as the bonding positioning device 10 of the first embodiment. The two ends of the first elastic clamping block 14 are respectively the first gripping end 35 and the first clamping end 39, and the two ends of the second elastic clamping block 15 are respectively the second gripping end 36 and the second clamping end 40. The first clamping end 39 and the second clamping end 40 cooperate with each other to clamp and release the bracket 27, and the limiting structure is provided on the first clamping end 39 and the second clamping end 40. A first gap is formed between the first clamping end 39 and the second clamping end 40, and a second gap is formed between the first gripping end 35 and the second gripping end 36. When a force is applied to the first gripping end 35 and the second gripping end 36 to bring them closer together, the first clamping end 39 and the second clamping end 40 move away from each other.

[0113] Specifically, the first holding end 35 is connected to the first clamping end 39 via a first connecting section 37 , and the second holding end 36 is connected to the second clamping end 40 via a second connecting section 38 .

[0114] The first connecting section 37 and the second connecting section 38 intersect in space to form a reverse clamping structure, that is, the first connecting section 37 and the second connecting section 38 form an X structure. When a force is applied to the first gripping end 35 and the second gripping end 36 to move closer to each other, the first clamping end 39 and the second clamping end 40 move away from each other. In a natural state, the first clamping end 39 and the second clamping end 40 move closer to each other to clamp the bracket 27 between the first clamping end 39 and the second clamping end 40. The reverse clamping structure is formed between the first connecting section 37 and the second connecting section 38, which is convenient for clamping and removing the bracket 27 and convenient for the orthodontist's operation.

[0115] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0116] Embodiment seven:

[0117] See also Fig.19 The present embodiment provides a bonding positioning device 10 for orthodontics, and its structure is basically the same as that of the bonding positioning device 10 of the first embodiment. The two ends of the first elastic clamping block 14 are respectively the first gripping end 35 and the first clamping end 39, and the two ends of the second elastic clamping block 15 are respectively the second gripping end 36 and the second clamping end 40. The first clamping end 39 and the second clamping end 40 cooperate with each other to clamp and release the bracket 27, and the limiting structure is provided on the first clamping end 39 and the second clamping end 40. A first gap is formed between the first clamping end 39 and the second clamping end 40, and a second gap is formed between the first gripping end 35 and the second gripping end 36. When a force is applied to the first gripping end 35 and the second gripping end 36 to bring them closer together, the first clamping end 39 and the second clamping end 40 move away from each other.

[0118] The first elastic clamping block 14 and the second elastic clamping block 15 are parallel to each other, the first holding end 35 and the first clamping end 39 are connected by the first connecting section 37, the second holding end 36 and the second clamping end 40 are connected by the second connecting section 38, and the first connecting section 37 and the second connecting section 38 are connected by a connecting block 41 to form an H-shaped structure.

[0119] Preferably, one end of the connecting block 41 is connected to the first connecting section 37 and the second connecting section 38 respectively, and the other end is connected to the tooth positioning structure 13 .

[0120] Preferably, the mesial and distal side walls of one end of the connecting block 41 are connected to the first connecting section 37 and the second connecting section 38 respectively, and the other end of the connecting block 41 is connected to the tooth positioning structure 13 .

[0121] Preferably, the first gripping end 35 and the second gripping end 36 are connected to the tooth positioning structure 13 respectively.

[0122] When a force is applied to the first gripping end 35 and the second gripping end 36 to move closer to each other, the first clamping end 39 and the second clamping end 40 move away from each other with the connection block 41 as support. In a natural state, the first clamping end 39 and the second clamping end 40 return to their original state, but since there is a pre-set elastic clamping force between the first clamping end 39 and the second clamping end 40, the first clamping end 39 and the second clamping end 40 can clamp the bracket 27 between the first clamping end 39 and the second clamping end 40.

[0123] The rest of the structure of this embodiment is the same as that of the first embodiment and will not be described in detail here.

[0124] It should be noted that the aforementioned “first, second…” does not represent a specific quantity or order, but is only used to distinguish the names.

[0125] The above-mentioned embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but the limitation of the scope of the present invention cannot be understood from them. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
