Description

Technical Field

[0001] This invention relates to the field of orthodontic medical device technology, and in particular to an accessory bonding aid for invisible orthodontic treatment. Background Technology

[0002] Clear Aligner Therapy is one of the mainstream treatment methods in the field of orthodontics. Its core process is as follows: based on the patient's digital dental arch model, a series of transparent thermoformed aligners are designed and manufactured. By gradually wearing the aligners, corrective forces are applied to achieve precise tooth movement.

[0003] An attachment is a small composite resin protrusion bonded to the labial / buccal surface of a tooth. It serves as a force transmission fulcrum between the appliance and the tooth, and is a crucial auxiliary structure for achieving complex orthodontic movements such as tooth rotation, intrusion, elongation, and overall tooth movement. The shape and bonding position of the attachment are predetermined during the digital design phase, and its bonding precision directly affects the orthodontic outcome.

[0004] The existing standard accessory bonding procedure is as follows:

[0005] ① Polish, acid etch (30 seconds), rinse, and isolate the target tooth surface from moisture;

[0006] ② Apply UV-curing adhesive, blow it thin with an air gun, and then expose it to light for 5-10 seconds to pre-cur the adhesive;

[0007] ③ Fill an appropriate amount of light-cured composite resin into the groove of the accessory positioning template (a transparent hot-press film with grooves pre-made on the template surface corresponding to the shape of the accessory);

[0008] ④ Place the resin-filled accessory template into the mouth, positioning it above the teeth;

[0009] ⑤ Use a UV curing lamp to cure the cut end or cheek side (20-40 seconds);

[0010] ⑥ Remove the accessory template, trim and polish the excess resin from the edges of the accessory, and complete the bonding.

[0011] In step ④, the degree to which the template fits the tooth surface, and in step ⑤, the accurate illumination by the light curing lamp, both depend on the doctor's / assistant's manual operation.

[0012] Defects in the existing standard accessory bonding process:

[0013] (1) Poor template fit leads to decreased attachment accuracy: The attachment template covers the entire dentition. Due to individual differences in dental arch morphology, template thickness and elasticity, there are often minute gaps between the template and the labial surface of the tooth at the attachment location, especially in the posterior teeth and rotated teeth. When gaps exist, the resin has already undergone slight flow before being exposed to light, resulting in morphological distortion and axial displacement of the attachment after curing, which directly affects the orthodontic mechanical effect.

[0014] (2) Reliance on four-handed operation, resulting in high labor costs: The routine clinical practice is for the doctor to hold the light curing lamp while the nurse holds a probe or forceps to press the area around the template attachment to make the template fit the tooth surface, which is a four-handed operation. Both the doctor and the patient need to cooperate during the operation, which is a long operation chain and increases chairside time and labor costs.

[0015] (3) The timing and intensity of pressure and light are difficult to control stably: When operating manually, the position, intensity and duration of pressure application cannot be precisely quantified. There are significant individual differences between different operators and different operations, resulting in poor repeatability of the quality of attachment bonding. Summary of the Invention

[0016] The present invention aims to provide an accessory bonding auxiliary device for invisible orthodontic treatment, so as to solve the problems mentioned in the background art.

[0017] To achieve the above objectives, the present invention provides the following technical solution:

[0018] An accessory bonding aid for invisible orthodontic treatment consists of an external pressure head assembly, an internal support assembly, and a control clamp body;

[0019] The internal support component is fixedly installed at one end of the control forceps body. When in use, it mainly abuts against the patient's palate and the inside of the teeth, providing a support point for subsequent attachment bonding work.

[0020] The external pressure head assembly is mounted on the control forceps body and is on the same axis as the internal support assembly. It can reciprocate back and forth along the control forceps body. When in use, it mainly presses against the attachment positioning template on the front side of the patient's teeth.

[0021] Meanwhile, the external pressure head assembly also integrates a photocuring module, which can be used to photocur the attachment after the attachment positioning template is pressed;

[0022] The control clamp body is equipped with a locking mechanism, a reset mechanism, a control module, and a power module.

By controlling the push-pull rod, and with the cooperation of the slider, the external tooth pressing component can be controlled to reciprocate back and forth along the control clamp body. The push-pull rod starts from one end of the external tooth pressing component, passes through the reset mechanism and the locking mechanism in sequence, and has a push button at the end extending out of the locking mechanism. The push-pull rod has a reset outer edge at the point where it passes through the reset mechanism, and the reset outer edge is used to connect with the reset mechanism. There are several accessory pressing components, which are assembled in a circumferential array on the side of the external tooth pressing component facing the inner support component. The photocuring module is integrated on the accessory pressing component and is controlled by the control module.

[0025] Preferably, the accessory clamping component comprises a fixing pin body, a buffer spring, and a clamping head assembly;

[0026] One end of the fixing nail body is fixedly assembled to the external tooth pressing member, the buffer spring is fixedly disposed at the end of the fixing nail body away from the external tooth pressing member, and the pressing head is fixedly disposed at the end of the buffer spring away from the fixing nail body.

[0027] Preferably, the clamping head is U-shaped, with the open surface of the U-shape facing the inner support component, and the photocuring module is located in the middle of the clamping head, with a built-in LED curing light source of 450~470 nm wavelength.

[0028] Preferably, the inner support assembly consists of an internal toothed support member and a support airbag;

[0029] The internal tooth support is fixedly mounted on one end of the control forceps body and is on the same axis as the external pressure head assembly. The support airbag is fixed on the side of the internal tooth support facing the external pressure head assembly and is used to directly contact the inside of the patient's teeth. The support airbag is controlled by the control module.

[0030] Preferably, the inner tooth support member has an extension plate at its lower edge facing the outer pressure head assembly, and the support airbag also has an extension edge.

[0031] Preferably, one end of the control clamp body is provided with a connector, through which the inner support assembly is fixedly assembled. The end away from the connector is provided with a handle. The control clamp body is provided with a guide groove. Through the cooperation of the guide groove and the bottom slider of the external tooth pressing component, the reset mechanism and the locking mechanism are sequentially fixed on the control clamp body. The power module is located at the bottom of the control clamp body. The control module is located on the side of the control clamp body near the handle. The control module integrates a timing function, which can control the irradiation time of the light curing module, generally 20s-40s.

[0032] Preferably, the guide groove of the control clamp body is provided with an electrode plate and electrically connected to the power supply, and the bottom of the slider of the external tooth pressing member is provided with an electrode point, which is achieved through the contact between the electrode plate and the electrode point.

[0033] Preferably, the main body of the reset mechanism is a reset component, the reset component has a reset through hole in the middle, the reset through hole has a reset cavity in the middle, the reset cavity has a reset spring, the push-pull rod passes through the reset through hole, and the reset outer edge of the push-pull rod is connected to the end of the reset spring away from the external pressure head assembly.

[0034] Preferably, the locking mechanism consists of a fixed locking element, a movable locking block, and a locking screw;

[0035] The fixed locking component is fixed to the control clamp body. The movable locking block and the fixed locking component are fitted into the upper right corner of the fixed locking component to form a complete cube, and a locking through hole is provided in the middle. The locking through hole and the reset through hole are on the same axis. The movable locking block and the fixed locking component are provided with locking threaded holes. The locking threaded holes are horizontally perpendicular to the upper part of the locking through hole. The locking screw is threadedly assembled in the locking threaded hole.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] (1) Solve the problem of poor template adhesion and improve the bonding accuracy of accessories.

[0038] This device achieves positioning and clamping of the attachment positioning template on three sides (outer, inner, and bottom) through an outer pressure head assembly (outer side), an inner support assembly (inner side), and a base (bottom), ensuring full fit between the template and the tooth surface. The U-shaped clamping head, with its open surface facing the inner support assembly, allows for further clamping and fixing of the attachment area, mimicking the action of tweezers pressing around the attachment, effectively preventing template warping. The attachment clamping component uses a buffer spring in conjunction with the clamping head, which can adaptively fit different patients' tooth shapes (anterior and posterior regions), forming a buffered contact to protect the teeth while ensuring fit. Through mechanized clamping, it completely eliminates the minute gaps between the template and the tooth surface, ensuring that the resin does not flow before curing, improving the accuracy of the attachment's shape and axis.

[0039] (2) Enables one-handed operation and reduces labor costs.

[0040] This device integrates the clamping and photocuring functions into one unit. The photocuring module is integrated on the external clamping head assembly, eliminating the need to hold the photocuring lamp separately. The external clamping head assembly is fixed and locked by locking screws and movable locking blocks. After clamping, the device can maintain the clamping force, eliminating the need for continuous pressing by medical personnel. Medical personnel only need to hold the handle of the control forceps body, push the push button to advance the external clamping head assembly, and tighten the locking screw to complete the clamping and fixing. This frees up the hands and eliminates the need for nurses to hold forceps to press the template. A single person can complete the entire accessory bonding process, significantly reducing labor costs.

[0041] (3) Achieve precise control over pressurization and illumination to improve repeatability.

[0042] A buffer spring provides cushioning to prevent excessive pressure from damaging teeth while ensuring sufficient clamping force. The control module has a built-in timer function to precisely control the irradiation time of the light-curing module (20-40 seconds), avoiding human error. The mechanized clamping and curing process eliminates individual differences in human operation, achieving highly consistent bonding quality between different operators and different operations. The light-curing module has a built-in LED curing light source with a wavelength of 450-470nm, which directly irradiates the attachment through the center of the clamping head, ensuring accurate light position and stable intensity. With the locking mechanism in place, the device can complete resin curing under continuous clamping, avoiding the problem of difficulty in coordinating the clamping and irradiation timing in traditional operations.

[0043] (4) Other effects

[0044] The reset spring in the reset mechanism can automatically drive the external pressure head assembly to reset after the locking mechanism is unlocked, reducing the number of steps for medical personnel. It controls the electrode plate in the guide groove of the forceps body to contact the electrode point at the bottom of the slider of the external tooth pressure member, providing power to the external pressure head assembly without affecting its reciprocating motion. The support airbag of the inner support assembly can fit against the inner side and bottom surface of the tooth, providing flexible support and enhancing patient comfort. The outer edge design of the inner tooth support and the support airbag can lift the bottom surface of the tooth, enhancing the three-sided positioning effect. Attached Figure Description

Detailed Implementation

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0054] like Figures 1-6 The present invention provides an accessory bonding auxiliary device for invisible orthodontic treatment, comprising an external pressure head assembly 1, an internal support assembly 2, and a control clamp body 3. The internal support assembly 2 is fixedly mounted on one end of the control clamp body 3 and, during use, mainly abuts against the patient's palatal side and the inner side of the teeth, providing a support point for subsequent accessory bonding. The external pressure head assembly 1 is mounted on the control clamp body 3, coaxial with the internal support assembly 2, and can reciprocate back and forth along the control clamp body 3. During use, it mainly presses against the accessory positioning template on the front side of the patient's teeth to tighten the template and prevent warping, thereby preventing the accessory from not fitting tightly to the teeth and affecting the bonding effect. At the same time, the external pressure head assembly 1 also integrates a light curing module 104, which can light-cur the accessory after tightening the positioning template.

[0055] The control clamp body 3 is equipped with a locking mechanism 301, a reset mechanism 302, a control module 303, and a power module 304. The control module 303 can remotely control the external pressure head assembly 1 and the internal support assembly 2. The power module 304 can provide energy to both to ensure their normal operation. The locking mechanism 301 can fix and lock the external pressure head assembly 1. In this way, after the medical personnel push the locking mechanism 301 to press the attachment positioning template on the front side of the patient's teeth, the locking mechanism 301 fixes and locks the external pressure head assembly 1. In conjunction with the light curing module 104, the attachment is continuously pressed and cured. At the same time, the medical personnel's hands are freed, and it can be operated with one hand. The reset mechanism 302 can automatically reset the external pressure head assembly 1 after the medical personnel unlock the locking mechanism 301 after the attachment bonding and fixing work is completed, reducing the operation of the medical personnel.

[0056] The external pressure head assembly 1 consists of an external toothed pressure member 101, an accessory clamping member 102, and a push-pull rod 103. The bottom of the external toothed pressure member 101 has a slider 1011, which is mounted on the control clamp body 3. The push-pull rod 103 is fixedly located at the middle of one side of the external toothed pressure member 101. Medical personnel can control the external toothed pressure member 101 to reciprocate along the control clamp body 3 by controlling the push-pull rod 103, which, in conjunction with the slider 1011, allows the external toothed pressure member 101 to move back and forth along the control clamp body 3. The push-pull rod 103 starts from one end of the external toothed pressure member 101, passes sequentially through the reset mechanism 302 and the locking mechanism 301, and has a push button 1031 at the end extending from the locking mechanism 301. The medical personnel can push the external pressure head assembly 1 by pressing the push button 1031. The push-pull rod 103 has a reset outer edge 1032 at the reset mechanism 302. The reset outer edge 1032 is used to connect with the reset mechanism 302, so that the reset mechanism 302 can drive the external pressure head assembly 1 to reset. There are several accessory clamping parts 102, which are assembled in a circumferential array on the side of the external toothed clamping part 101 facing the inner support assembly 2. At the same time, the light curing module 104 is integrated on the accessory clamping part 102 and is controlled by the control module 303. After the accessory clamping part 102 clamps the accessory, the light curing module 104 is activated to directly cure the accessory.

[0057] Furthermore, the accessory clamping component 102 is composed of a fixed nail body 1021, a buffer spring 1022, and a clamping head 1023. One end of the fixed nail body 1021 is fixedly mounted on the external tooth clamping component 101. The buffer spring 1022 is fixedly disposed at the end of the fixed nail body 1021 away from the external tooth clamping component 101. The clamping head 1023 is fixedly disposed at the end of the buffer spring 1022 away from the fixed nail body 1021. In this way, after the medical personnel push the external clamping head assembly 1 and press the accessory clamping component 102 against the accessory positioning template, a buffer contact is formed to protect the patient's teeth. At the same time, the buffer spring 1022 and the clamping head 1023 have a certain angle adjustment function, which can adaptively fit the anterior and posterior tooth areas of different patients with different tooth shapes.

[0058] Furthermore, the clamping head 1023 is U-shaped, with the open surface of the U-shape facing the inner support component 2. The light curing module 104 is located in the middle of the clamping head 1023. The light curing module 104 has a built-in LED curing light source with a wavelength of 450~470 nm. Thus, after the accessory clamping component 102 is pressed against the accessory positioning template, the U-shaped clamping head 1023 can further clamp and fix the accessory area, simulating the action of medical personnel using tweezers to press the accessory around, preventing the accessory positioning template from lifting up, and making it fully fit with the tooth surface. Then, the light curing module 104 is activated to directly perform light curing, making the accessory bonding work more efficient and accurate.

[0059] The inner support assembly 2 consists of an inner tooth support 201 and a support airbag 202. The inner tooth support 201 is fixedly installed at one end of the control clamp body 3 and is on the same axis as the outer pressure head assembly 1. The support airbag 202 is fixed on the side of the inner tooth support 201 facing the outer pressure head assembly 1 and is used to directly contact the inner side of the patient's teeth. The support airbag 202 is controlled by the control module 303.

[0060] Furthermore, the inner tooth support 201 has an outer extension plate 2011 at the lower edge of the side facing the outer pressure head assembly 1, and the support airbag 202 also has an outer extension edge 2021. In this way, while supporting the inner side of the patient's teeth, it can also lift the patient's tooth surface. After the medical personnel install the accessory positioning template on the patient's teeth, the outer pressure head assembly 1 can be used to position and press the accessory positioning template on the outer, inner and bottom sides to ensure the accuracy of the accessory bonding position.

[0061] One end of the control clamp body 3 is provided with a connector 305, through which the inner support component 2 is fixedly assembled. The end away from the connector 305 is provided with a handle 306, which is convenient for medical personnel to hold and operate the device. The control clamp body 3 is provided with a guide groove 307. Through the cooperation of the guide groove 307 and the bottom slider 1011 of the external tooth pressing part 101, the external pressure head component 1 is assembled on the control clamp body 3. The reset mechanism 302 and the locking mechanism 301 are fixedly arranged on the control clamp body 3 in sequence to lock and reset the external pressure head component 1. The power module 304 is located at the bottom of the control clamp body 3 to provide power to the external pressure head component 1 and the inner support component 2. The control module 303 is located on the side of the control clamp body 3 near the handle 306, which is convenient for medical personnel to operate and control the external pressure head component 1 and the inner support component 2.

[0062] Furthermore, an electrode plate 308 is provided in the guide groove 307 of the control clamp body 3 and is electrically connected to the power supply. An electrode point 1012 is provided at the bottom of the slider 1011 of the external tooth pressing member 101. Through the contact between the electrode plate 308 and the electrode point 1012, power is provided to the external pressing head assembly 1 without affecting its reciprocating linear motion, thus ensuring the operation of the photocuring module 104.

[0063] Furthermore, the main body of the reset mechanism 302 is a reset component 3021. A reset through hole 3022 is provided in the middle of the reset component 3021. A reset cavity 3023 is provided in the middle of the reset through hole 3022. A reset spring 3024 is provided in the reset cavity 3023. The push-pull rod 103 passes through the reset through hole 3022. The reset outer edge 1032 provided on the push-pull rod 103 is connected to the end of the reset spring 3024 away from the external pressure head assembly 1. Thus, when the medical personnel press the push-pull rod 103, the external pressure head assembly 1 is driven to press the accessory. After the accessory is fixed, the reset spring 3024 rebounds and drives the push-pull rod 103 to retract via the reset outer edge 1032, thereby realizing the reset of the external pressure head assembly 1.

[0064] Furthermore, the locking mechanism 301 consists of a fixed locking member 3011, a movable locking block 3012, and a locking screw 3013. The fixed locking member 3011 is fixed to the control clamp body 3. The movable locking block 3012 and the fixed locking member 3011 are fitted into the upper right corner of the fixed locking member 3011 to form a complete cube, and a locking through hole 3014 is provided in the middle. The locking through hole 3014 and the reset through hole 3022 are on the same axis. Locking threaded holes 3012 and the fixed locking member 3011 are provided on the upper part of the movable locking block 3012 and the fixed locking member 3011. 15. The locking threaded hole 3015 is horizontally perpendicular to the locking through hole 3014 above. The locking screw 3013 is threaded into the locking threaded hole 3015. Thus, after the medical personnel press the external pressure head assembly 1 to the attachment, they can tighten the locking screw 3013 to drive the movable locking block 3012 to fit against and fix the locking part 3011. The side of the movable locking block 3012 that contacts the push-pull rod 103 will press against it to lock the external pressure head assembly 1. This allows the pressure to be maintained after the external pressure head assembly 1 presses the attachment, without the need for the medical personnel to press continuously.

[0065] Furthermore, the control module 303 integrates a timing function, which can control the irradiation time of the photocuring module 104, typically 20s-40s.

[0066] The specific implementation process is as follows:

[0067] (1) Preliminary preparations

[0068] Tooth surface treatment: Polishing, acid etching (30 seconds), rinsing, and moisture isolation are performed on the target tooth surface;

[0069] Apply adhesive: Apply UV-curable adhesive, blow it thin with an air gun, and then expose it to light for 5-10 seconds to pre-cur the adhesive;

[0070] Resin filling: Fill an appropriate amount of light-cured composite resin into the groove of the accessory positioning template (transparent hot-press film), and put the resin-filled accessory template into the mouth so that it is positioned on the teeth.

[0071] (2) Device positioning operation

[0072] The internal support component 2 (internal tooth support 201 and support airbag 202) is placed against the patient's palate and the inside of the teeth to provide support points; the support airbag 202 is activated by the control module 303 to make it fit against the inside of the teeth and the bottom of the teeth.

[0073] (3) Press the template

[0074] The medical personnel press the push button 1031 on the push-pull rod 103 to advance the external pressure head assembly 1. The external pressure head assembly 1 moves forward along the control forceps body 3. The accessory clamping member 102 presses against the front side of the teeth of the accessory positioning template. The buffer spring 1022 and the clamping head 1023 adaptively conform to different tooth shapes to form a buffer contact. The U-shaped clamping head 1023 further clamps and fixes the accessory area, simulating the action of tweezers pressing on the area around the accessory.

[0075] (3) Locking and fixing

[0076] Tighten the locking screw 3013, causing the movable locking block 3012 to fit against the fixed locking component 3011. The movable locking block 3012 presses against the push-pull rod 103, locking the external pressure head assembly 1 and maintaining the pressure of the device without requiring continuous pressing by medical personnel.

[0077] (4) Light curing

[0078] Start the control module 303 to activate the photocuring module 104. The LED curing light source (wavelength 450~470nm) irradiates the accessory through the photocuring module 104 in the middle of the clamping head 1023. The control module 303 has a built-in timer function to control the irradiation time to 20~40 seconds, and the resin curing is completed under continuous clamping.

[0079] (5) Follow-up processing

[0080] After curing, loosen the locking screw 3013, unlock the locking mechanism 301, and the return spring 3024 rebounds, driving the push-pull rod 103 to retract via the outer edge 1032. The outer pressure head assembly 1 automatically resets to the initial position. Remove the accessory template, trim and polish the excess resin on the edge of the accessory to complete the bonding.
