Description

Technical Field

[0001] This utility model relates to the field of orthodontic force acquisition, and in particular to a high-efficiency orthodontic force acquisition device for invisible orthodontic appliances. Background Technology

[0002] Force acquisition for invisible aligners refers to the technology of quantitatively measuring the three-dimensional mechanical forces exerted on teeth during the wearing of aligners using specialized devices. A semi-circular base simulates the dental arch, with multiple multi-dimensional force sensors arranged in a ring around the base's edge. These sensors are connected to the simulated teeth via force transmission rods, transmitting real-time force data on the invisible aligners applied to the teeth. Combined with simulated skull and upper and lower jaw tooth models, this simulates a realistic occlusal relationship, ensuring the measurement environment closely approximates physiological conditions. Force acquisition is a core element in the transformation of invisible orthodontic technology from experience-based to precision-based approaches. By quantifying biomechanical effects, it provides a scientific basis for personalized treatment design, optimization of complex cases, and material innovation.

[0003] For example, patent number (CN206453866U) discloses a force acquisition device for invisible aligners, comprising: a semi-circular base; simulated mandibular teeth to be orthodontized and anchored; multiple sensor supports fixed in a ring array along the edge of the base; multiple multi-dimensional force sensors closely attached to the inner side of each sensor support; multiple force transmission rods respectively connecting each tooth of the simulated mandibular teeth to be orthodontized and anchored to the corresponding multi-dimensional force sensors; multiple connectors respectively connecting and fixing each force transmission rod, the corresponding multi-dimensional force sensor, and the corresponding sensor support; a pair of support rods vertically fixed to the base; a simulated skull hinged to the top of the support rods; and simulated maxillary teeth fixed to the simulated skull. This invention can accurately acquire the force conditions of all teeth under the action of the invisible aligner.

[0004] Currently, the force acquisition devices for high-efficiency invisible aligners have certain limitations in their model structure. Due to the different dental conditions of patients, the existing device's tooth model is difficult to simulate in a targeted manner, which further affects the accuracy of the force acquisition data collected by the device.

[0005] Therefore, to address the above issues, a modular and efficient force acquisition device for invisible orthodontic appliances can be designed. Utility Model Content

[0006] To overcome the problem that existing devices for acquiring force in high-efficiency invisible aligners are difficult to simulate in a targeted manner using dental models, which further affects the accuracy of the acquired data.

[0007] The technical solution of this utility model is as follows: a high-efficiency invisible aligner force acquisition device, including a base and a simulated tooth socket. A module mounting rod is installed inside the simulated tooth socket. The upper end of the module mounting rod extends to the outside of the simulated tooth socket and a tooth module is fixedly installed thereon. An arc-shaped groove is formed on the surface of the module mounting rod. A movable groove is formed on the inner surface of the simulated tooth socket. A compression spring is fixedly installed inside the movable groove, and a locking bead is fixedly installed on the compression spring. An installation groove is formed at the upper end of the base. A limit plate is fixedly installed on the upper side inside the installation groove. A limit block and an installation seat are provided inside the installation groove. A threaded rod is rotatably connected to the limit block. A knob is fixedly installed at the end of the threaded rod away from the limit block, extending to the outside of the base. A locking groove is fixedly installed at the upper end of the base, located on the side of the installation groove. A magnetic plate is fixedly installed at the lower end inside the locking groove. A locking ring is fixedly installed on the surface of the threaded rod, located inside the locking groove. A locking block is provided inside the locking groove. An orthodontic force acquisition component is fixedly installed at the upper end of the installation seat.

[0008] Preferably, the orthodontic appliance is mounted on the dental module, with each sensor support corresponding to a simulated tooth socket and dental module. Each multidimensional force sensor is correspondingly and closely attached to its respective sensor support without contacting the bottom surface of the base. The multidimensional force sensor is a device that converts the force value into a relevant electrical signal to detect the orthodontic force and torque on the teeth. Each force transmission link connects each tooth to its corresponding multidimensional force sensor to transmit the force and torque experienced by the teeth to the multidimensional force sensor. This avoids the problem of direct contact between the sensor and the small space around the teeth, which is too large for direct contact. The orthodontic force and torque experienced by each tooth or target tooth are measured. Upon receiving the force information of the teeth, the multidimensional force sensor outputs a corresponding six-dimensional force and torque value, which is reflected by a voltage signal and then analyzed and displayed by a subsequent testing system.

[0009] Preferably, the simulated tooth socket is engaged with the module mounting rod, and the arc-shaped groove and the movable slot are distributed in a ring array.

[0010] Preferably, the surface of the locking bead is slidably connected to the movable groove, and the end of the locking bead away from the compression spring extends to the outside of the movable groove and matches the arc-shaped groove.

[0011] Preferably, the mounting base is engaged with the mounting slot, and the limiting block is engaged with the mounting base.

[0012] Preferably, the surface of the threaded rod is threadedly connected to the base, the locking block engages with the locking groove, the locking ring fits into the locking block, and the locking block is adapted to the threaded rod.

[0013] Preferably, the orthopedic force acquisition component includes a sensor support, on which a multi-dimensional force sensor is fixedly installed.

[0014] Preferably, a force transmission link is fixedly installed on the multidimensional force sensor, and the force transmission link is fixedly connected to the simulated tooth socket.

[0015] The beneficial effects of this utility model are:

[0016] 1. This high-efficiency invisible aligner uses an array of locking beads that, in conjunction with a spring structure of appropriate elasticity, can be squeezed and pushed to ensure they press against the arc-shaped groove. This structure ensures both the stability of the module mounting rod's locking and installation and the ease of disassembly and installation. Combined with modular dental modules, it allows for flexible assembly of the device. Customized dental modules can be tailored to the patient's specific needs, enabling rapid modular assembly and installation. This allows the force acquisition device to perform targeted simulation and acquisition based on a dental model identical to the patient's, further ensuring the accuracy of the force acquisition data.

[0017] 2. This high-efficiency invisible aligner uses an orthodontic force acquisition device. The orthodontic force acquisition components are connected one-to-one with simulated tooth sockets, facilitating accurate data acquisition. The device can also be modularly assembled, with simulated tooth sockets used to assemble modular tooth modules. The orthodontic force acquisition components themselves are also modular, allowing for individual disassembly, repair, and replacement. The disassembly and assembly structure is simple and convenient, and the installation is stable and secure. If a single acquisition component is damaged, only the corresponding module needs to be replaced, eliminating the need to scrap the entire device. Standardized interface specifications reduce customization costs and promote equipment compatibility within the industry. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This utility model provides an embodiment of a high-efficiency invisible aligner force acquisition device, including a base 1 and a simulated dental socket 2. A module mounting rod 3 is disposed inside the simulated dental socket 2. A tooth module 4 is fixedly mounted on the upper end of the module mounting rod 3 extending to the outer side of the simulated dental socket 2. An arc-shaped groove 5 is formed on the surface of the module mounting rod 3. A movable groove 6 is formed on the inner surface of the simulated dental socket 2. A compression spring 7 is fixedly mounted inside the movable groove 6, and a locking bead 8 is fixedly mounted on the compression spring 7. An installation groove 9 is formed at the upper end of the base 1. A limiting plate 10 is fixedly mounted on the upper side inside the installation groove 9. A limiting block 11 and an installation seat 12 are disposed inside the installation groove 9. A threaded rod 13 is rotatably connected to the limiting block 11. The end of the threaded rod 13 away from the limiting block 11 extends to the outer side of the base 1 and is fixedly mounted. The device includes a knob 14, a locking groove 15 fixedly installed on the upper end of the base 1 at the side of the mounting groove 9, a magnetic suction plate 16 fixedly installed at the lower end inside the locking groove 15, a locking ring 17 fixedly installed on the surface of the threaded rod 13 at the inner side of the locking groove 15, a locking block 18 provided on the inner side of the locking groove 15, and an orthodontic force acquisition component fixedly installed on the upper end of the mounting base 12. The compression spring 7 cooperates with the locking bead 8 to abut against the arc-shaped groove 5. This structure can ensure the stability of the engagement between the module mounting rod 3 and the simulated tooth socket 2, and facilitate quick disassembly and installation. Combined with the modular tooth module 4, the tooth module 4 can be customized according to the patient's condition. The quick disassembly and assembly structure can complete the modular combination of the corresponding situation, so that the orthodontic force acquisition device can perform targeted simulation acquisition work according to the same tooth model as the patient.

[0026] Please see Figures 1-4In this embodiment, the simulated tooth socket 2 is engaged with the module mounting rod 3. The arc-shaped groove 5 and the movable groove 6 are both arranged in a ring array. The surface of the engagement bead 8 is slidably connected to the movable groove 6. The end of the engagement bead 8 away from the compression spring 7 extends to the outside of the movable groove 6 and matches the arc-shaped groove 5. The tooth module 4 can be customized one by one according to the actual situation of the patient. The module mounting rod 3 can be engaged with the simulated tooth socket 2. The module mounting rod 3 and the simulated tooth socket 2 are provided with a unilateral directional structure to ensure the stability of the tooth module 4 and prevent rotational displacement. The compression spring 7 can drive the engagement bead 8 to fit tightly against the arc-shaped groove 5 (the compression spring 7 is selected with appropriate size and force to ensure that the module can be installed stably and avoid affecting the acquisition work of the equipment), ensuring the stability of the tooth module 4 engagement installation. The orthodontic appliance can be installed on the tooth module 4, and the equipment can be started to complete the orthodontic force acquisition work.

[0027] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, the mounting base 12 is engaged with the mounting groove 9, the limiting block 11 is engaged with the mounting base 12, the surface of the threaded rod 13 is threadedly connected to the base 1, the locking block 18 is engaged with the locking groove 15, the locking ring 17 and the locking block 18 are mutually fitted, the locking block 18 and the threaded rod 13 are mutually adapted, and the orthodontic force acquisition component includes a sensor support 19, a multi-dimensional force sensor 20 is fixedly mounted on the sensor support 19, a force transmission link 21 is fixedly mounted on the multi-dimensional force sensor 20, and the force transmission link 21 is fixedly connected to the simulated tooth socket 2. Knob 14 can turn the threaded rod 13, and the limiting block 11 can move into the reserved cavity of the mounting slot 9. The sliding mounting seat 12 can move away from the limiting plate 10, making it easier to remove the mounting seat 12 for replacement. The limiting block 11 can also be inserted into the slot of the mounting seat 12 and hold the mounting seat 12 against it. Together with the limiting plate 10 on the other side, the installation work is completed. At this time, the locking ring 17 is located at the outermost side of the locking slot 15. The locking block 18 can be inserted into the locking slot 15. The magnetic plate 16 can attract the locking block 18 to ensure stable engagement and complete the locking work.

[0028] During operation, the dental module 4 is customized according to the patient's actual situation. The module installation rod 3 of the customized dental module 4 is inserted into the simulated tooth socket 2. The compression spring 7 drives the locking bead 8 to fit tightly into the arc-shaped groove 5 to ensure the stability of the dental module 4 during installation. The orthodontic appliance is installed on the dental module 4, and the equipment is started to complete the orthodontic force acquisition. When it is necessary to repair or replace a certain orthodontic force acquisition component, the locking block 18 is pulled out, and the threaded rod 13 is turned by the knob 14 to move the limiting block 11 into the reserved cavity of the installation slot 9. This further facilitates the sliding mounting seat 12 away from the limiting plate 10. The mounting seat 12 is removed, and the new orthodontic force acquisition component is installed into the installation slot 9. The knob 14 is turned again to make the limiting block 11 abut against the slot of the mounting seat 12 to complete the installation. At this time, the locking ring 17 is located at the outermost side of the locking slot 15, which makes it easy to re-lock the locking block 18 into the locking slot 15 to complete the locking work.

[0029] Through the above steps, the compression spring 7, in conjunction with the locking bead 8, abuts against the arc-shaped groove 5. This structure ensures the stability of the engagement between the module mounting rod 3 and the simulated tooth socket 2, while also facilitating quick disassembly and installation. Combined with the modular tooth module 4, which is customized according to the patient's specific condition, the modular combination of the corresponding situation is completed using the quick disassembly and assembly structure. This allows the orthodontic force acquisition device to perform targeted simulation and acquisition based on the same tooth model as the patient. This solves the problem that existing devices for acquiring orthodontic force in high-efficiency invisible aligners are difficult to simulate with a specific tooth model, which further affects the accuracy of the acquired data.
