Description

Technical Field

[0001] This invention relates to the field of orthodontic fixed orthodontic technology, and in particular to a directional low-friction orthodontic fixed appliance with a switchable orthodontic system and its method of use. Background Technology

[0002] In orthodontic clinical treatment, fixed appliances are the core equipment, mainly composed of brackets and buccal tubes. Currently mainstream orthodontic systems, such as Roth, MBT, and Damon, each have their own advantages and limitations. For example, the Roth system can reduce the risk of relapse but has insufficient torque on the upper incisors; the MBT system uses thin wires and light force but may cause excessive lingual inclination of the lower incisors; the Damon system has excellent arch expansion and low friction, but it is difficult to adjust rotated teeth and is very expensive. These systems are independent of each other and cannot be flexibly switched during a single treatment session, making it difficult to meet complex clinical needs.

[0003] In clinical practice, situations often arise where it is necessary to change orthodontic systems. Examples include: individual teeth requiring reverse bonding of brackets; mismatched upper and lower jaw widths necessitating different systems; and adjustments to anterior tooth torque during gap closing. Traditional solutions require dentists to remove the old appliances and bond new ones, which not only increases the dentist's workload and medical supplies but also causes repeated enamel wear and additional financial burden for the patient.

[0004] In addition, there is a huge frictional force between the archwire and the buccal tube when moving molars. This not only requires overcoming the resistance of the periodontal ligament, but also easily leads to anchorage loss, affecting the orthodontic effect.

[0005] Existing orthodontic technologies suffer from several drawbacks: independent and singular treatment systems cannot flexibly adapt to dynamic treatment needs; changing appliances is cumbersome, damages the patient's tooth structure, and is costly; and the high friction during molar movement makes anchorage control difficult. Therefore, there is an urgent need to develop a personalized, efficient, and minimally invasive fixed orthodontic treatment system. Summary of the Invention

[0006] The purpose of this invention is to address the technical deficiencies in the existing technology by providing a directional low-friction orthodontic fixed appliance with a switchable orthodontic system.

[0007] Another object of the present invention is to provide a method of using a directional low-friction orthodontic fixed appliance with a switchable orthodontic system.

[0008] The technical solution adopted to achieve the purpose of this invention is: A directional low-friction orthodontic fixed appliance with a switchable orthodontic system includes an artificial intelligence host, a fixed appliance assembly, a special clamping tool for holding the fixed appliance assembly, and a storage device for storing the fixed appliance assembly and the special clamping tool. The artificial intelligence host includes an information input module, a chip, and an information output module. The information output module outputs a voice output system and a touch screen. The information input module receives patient information and orthodontic needs and transmits them to the chip. It outputs a recommended plan through the voice output system and displays the position of the recommended fixed orthodontic appliance for each tooth in the storage device on the touch screen. The fixed orthodontic appliance assembly includes multiple bracket slots, multiple replaceable bracket cores, and at least one directional low-friction buccal tube disposed on the anchorage tooth; the bracket slot includes a first bonding base plate for fixed bonding with the corresponding tooth surface, a receiving chamber for cooperating with the bracket core, a locking mechanism for opening or closing the receiving chamber, and a gingival ligation wing for connecting the connecting device. The bracket core includes a bottom wall, a gingival surface, and a ligature. The surface, the gingival wing that mates with the bracket slot to accommodate the cavity, and The gingival margin and The mesial and distal corners of the wing are provided with a mating structure that cooperates with a special clamping tool; the directional low-friction buccal tube includes a second adhesive base plate fixed to the buccal surface of the molar, a lumen for the connecting device to pass through, and a one-way resistance mechanism, which is configured to provide a first resistance in a first direction of movement of the connecting device and a second resistance greater than the first resistance in the opposite second direction of movement.

[0009] In the above technical solution, the receiving chamber of the bracket slot is formed inside the bracket slot and along the gum line. A track extending in a certain direction, through which the bracket core can be slidably inserted into or removed from the bracket slot.

[0010] In the above technical solution, the locking mechanism of the bracket slot is a sliding cover type latch, which is set on the cheek surface of the bracket slot through a sliding connection.

[0011] In the above technical solution, each bracket core has a tooth position number on its buccal side. The different bracket cores carry preset archwire channel data for different orthodontic systems, including Roth system data, MBT system data, Damon system high torque data, Damon system normal torque data, and Damon system low torque data.

[0012] In the above technical solution, the mating structure is disposed on the gingival wing and The circular holes at the near and far mid-angles of the flange.

[0013] In the above technical solution, the lumen of the directional low-friction buccal tube has a groove, and the unidirectional resistance mechanism includes a groove disposed on the gingival wall or... The wall has a one-way ball bearing and a limiting structure set in a groove. The one-way ball bearing is partially housed in the groove and can rotate. The surface of the one-way ball bearing protrudes from the cavity to contact the bow wire. The limiting structure is used to restrict the one-way ball bearing to rotate in only one direction.

[0014] In the above technical solution, the directional low-friction buccal tube is divided into a mesial-central directional low-friction buccal tube and a distal-central directional low-friction buccal tube. The mesial-central directional low-friction buccal tube is further divided into a right mesial-central directional low-friction buccal tube and a left mesial-central directional low-friction buccal tube. For the right mesial-central directional low-friction buccal tube, the limiting structure is configured to allow only clockwise rotation of the unidirectional ball bearing. For the left mesial-central directional low-friction buccal tube, the limiting structure is configured to allow only counterclockwise rotation of the unidirectional ball bearing.

[0015] In the above technical solution, the special clamping tool is a rod-shaped structure, including a first end and two rods integrally connected to the first end. Each rod has a second end at its other end. The first end is a single-headed flat shape, used to insert into and move the sliding cover lock on the tray. The second end is a double-headed structure with a tapered front end and a groove. A spring mechanism is provided at the hinge axis of the two rods.

[0016] In the above technical solution, the storage device is a layered pull-out box, including a first layer, a second layer, and a third layer. The first layer is used to store the bracket slots and the special clamping tools; the second layer is used to store the bracket core carrying Roth system data and MBT system data, as well as the mesial and distal movement directional low-friction orthodontic appliance for the first molar; the third layer is used to store the bracket core carrying Damon system data, as well as the mesial and distal movement directional low-friction orthodontic appliance for the second molar.

[0017] In another aspect of the present invention, the method of using the directional low-friction orthodontic fixed appliance of the switchable orthodontic system is characterized by comprising the following steps: Step a, Initial assembly and bonding: The AI ​​host obtains personalized orthodontic system recommendations for the patient's dentition. According to the recommended scheme, select the corresponding tray core from the storage device; The bracket core is clamped by the second end of the special clamping tool and inserted into the receiving chamber of the bracket slot, and the locking mechanism is closed to form a complete orthodontic appliance; The assembled orthodontic appliance is bonded to the tooth surface, and the selected directional low-friction orthodontic appliance is bonded to the anchorage tooth surface; Step b, kernel replacement: When it is necessary to change the orthodontic system, use the first end of the special clamping tool to open the locking mechanism of the bracket slot on the target tooth position; The original tray core inside the tray slot is clamped and removed using the second end of the special clamping tool. The new tray core is installed into the receiving cavity of the tray slot using a special clamping tool, and the locking mechanism is then closed.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up an artificial intelligence host, can recommend the optimal orthodontic system for each tooth based on specific clinical case characteristics (such as malocclusion type and tooth movement requirements). This effectively solves the selection bias problem that may exist in traditional reliance on doctors' personal experience, especially assisting doctors with insufficient experience, realizing intelligent assistance and standardization of diagnosis and treatment decisions, thereby improving the overall accuracy and predictability of orthodontic treatment.

[0019] 2. This invention, through its modular design of base components (bracket slots) and replaceable functional cores (bracket cores), fundamentally solves the problem of existing orthodontic systems being independent and unable to be switched. During treatment, doctors can directly replace different bracket cores in the mouth according to the different stages of tooth movement without removing the base components bonded to the tooth surface. This enables dynamic and seamless switching between different orthodontic systems such as Roth, MBT, and Damon within the same treatment course, greatly improving the adaptability of fixed orthodontics to handle complex cases and truly achieving personalized treatment.

[0020] 3. This invention eliminates the need to remove and re-bond the bracket base when replacing the orthodontic system, avoiding the irreversible wear on tooth enamel caused by repeated bonding in traditional methods. This significantly reduces the risk of physical injury and sensitivity for patients. At the same time, this method also greatly reduces the waste of orthodontic appliances, saves medical consumables, and lowers patients' medical expenses, demonstrating the dual advantages of being minimally invasive and economical.

[0021] 4. This invention utilizes a directional low-friction appliance (directional low-friction buccal tube) placed on the anchorage molar. Through its internal unidirectional ball bearings and limiting structure, it achieves near-zero friction in the predetermined movement direction while maintaining high friction in the opposite direction. This directional low-friction characteristic allows the molar to effectively resist unintended movement when used as anchorage, and to slide easily and efficiently when active movement is required, greatly reducing the risk of anchorage loss. Combined with implant devices, it enables rapid overall movement of the molar or efficient closure of extraction gaps, thereby significantly shortening the treatment duration and improving orthodontic efficiency.

[0022] 5. This invention forms a complete operational closed loop through the matching special clamping tools and layered storage device. The special clamping tool is specially optimized for the picking and placing of the core and the opening and closing of the lock, making the operation precise and labor-saving; the orderly partitioning management of the storage box enables a wide variety of components to be quickly and accurately located and retrieved, greatly improving clinical work efficiency, reducing management chaos, and ensuring the smoothness of treatment.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0033] It should be noted that, as mentioned in the text, "mesial" refers to the direction in which teeth are closer to the facial midline; "distal" refers to the direction in which teeth are farther from the facial midline; and "gingival" refers to the direction towards the gums. "Towards" refers to the direction towards the occlusal surface of the teeth; "cheek surface" refers to the surface of the back teeth near the cheek.

[0034] Example 1 A directional low-friction orthodontic fixed appliance with a switchable orthodontic system includes an artificial intelligence host 100, a fixed appliance assembly, a special clamping tool 300, and a storage device 400 for storing the fixed appliance assembly and the special clamping tool 300.

[0035] Reference Figure 1 The artificial intelligence host 100 includes a housing (not shown in the figure), an information input module, a chip 102, and an information output module. The information input module is preferably a voice recognition system 101. The chip 102 pre-stores a database containing information on various orthodontic systems, patient information, and corresponding orthodontic recommendations based on orthodontic needs. The artificial intelligence host 100 is configured to receive user input and output orthodontic system recommendations for specific tooth positions based on the database. The information input module includes the voice recognition system 102. The information output module includes a voice output system 103 and a touchscreen display 104. The housing is used to house and protect the internal components of the artificial intelligence host 100. Furthermore, the voice recognition system 101 is used to receive the patient's basic information and orthodontic needs described by the doctor's voice, such as "anterior teeth inward inclination and deep overbite," for input, making the operation convenient. The chip 102 receives the patient's basic information and orthodontic needs input by the voice recognition system 101. After analyzing and calculating the data in conjunction with the database, it recommends the optimal orthodontic system for each specific tooth position, such as the upper right lateral incisor or the lower left first premolar, to the doctor through the voice output system 103. For example, "Damn low torque bracket core is recommended for tooth #11," and explains the reason for the recommendation. At the same time, the touch screen 104 displays the recommendation results in a graphical interface, and specifically shows the specific layer and position of the recommended bracket core in the storage device 400, which is described later, so that the doctor can quickly locate and retrieve it. The chip 102 is the computing core of the artificial intelligence host 100. It has a large database pre-stored in it, which contains various malocclusion types, such as Class II and Class III malocclusion, corresponding treatment methods such as arch expansion and extraction orthodontics, and detailed orthodontic system information, including the indications, torque, axial tilt angle, internal and external bending, and other preset data for Roth, MBT, and Damon high / medium / low torque systems. The fixed orthodontic appliance assembly includes multiple base components, multiple replaceable functional cores detachably housed within the base components, and different functional cores carrying preset archwire channel data for different orthodontic systems, and at least one directional low-friction buccal tube appliance set on the anchorage tooth. The base component is a bracket slot 210, each of which is fixedly bonded to the tooth surface. The functional core is a bracket core 220. The bracket slots 210 and the bracket core 220 include five types: bilateral maxillary and mandibular second premolars, first premolars, canines, lateral incisors, and central incisors. The bracket core 220 is detachably connected to the corresponding bracket slot 210 of the tooth. The directional low-friction buccal tube appliance is set on the anchorage tooth and includes a accommodating orthodontic appliance. The archwire has a lumen 231, within which a one-way resistance mechanism is provided. The one-way resistance mechanism is configured to provide a first resistance in a first direction of movement of the orthodontic archwire and a second resistance greater than the first resistance in the opposite second direction of movement. The artificial intelligence host 100 is used to receive the patient's basic information and output the treatment plan and the specific location of the recommended bracket core 220 in the storage device 400. The special clamping tool 300 is used to clamp the bracket slot 210 and the bracket core 220.

[0036] Reference Figure 2 The bracket slot 210 is a portion permanently bonded to the tooth surface, including: a receiving chamber 211, a locking mechanism 212, a first bonding base plate 213, a gingival ligation wing 214, and... The ligature wing 215; the receiving chamber 211 is formed inside the bracket slot 210 and along the gingiva. The directional extending track, the receiving chamber 211 is located at the gingival ligation wing 214 and Between the ligature wings 215, the locking mechanism 212 is a sliding cover type lock, which is set on the cheek surface of the bracket slot 210 by sliding connection. The doctor can use a special clamping tool 300 to make it move along the gum line. Slide towards, thereby exposing or closing the opening of the receiving chamber 211 below; the gingival ligation wing 214 and The ligature wing 215 is used for ligating bowwires or rubber chains; Traditional straight wire brackets have fixed groove data. Once selected and bonded, the orthodontic plan that can be implemented throughout the treatment process is locked. If it is necessary to change the orthodontic system, such as from the Roth system to the MBT system, all brackets must be pried off and a new set must be bonded, which is a complicated and costly process.

[0037] Reference Figure 3 The bracket core 220 includes a bottom wall 221 and a gingival surface 222. Face 223, gingival wing 224 and Edge 225; The bottom wall 221 is thick and inelastic to ensure structural stability. Each bracket core 220 has a tooth position number marking on the buccal side of its bottom wall 221, such as "11" or "31," for easy identification and to ensure accurate installation of the core onto the corresponding tooth position bracket body; The gingival surface 222 and Surface 223 is made of a slightly elastic material, such as medical-grade elastic polymer, and is relatively thin, giving it a certain degree of deformation capability; the gingival wing 224 and The gingival wing 225 extends from the bracket core 220 body and is used to mate with the receiving chamber 211 of the bracket slot 210. The gingival wing 224 and The near and far-middle corners of the flange 225 are provided with a mating structure that cooperates with the special clamping tool 300. Furthermore, the mating structure is a circular hole 226. The bracket core 220 in this embodiment is a pluggable module that carries data from different orthodontic systems. Its core working principle is to quickly change the orthodontic mechanics of the bracket body bonded to the tooth surface by replacing the core with different preset archwire channel parameters (such as axial tilt, torque angle, and retraction / abduction values). This allows a single bracket body to adapt to multiple mainstream orthodontic techniques. The bracket core 220 system in this embodiment transforms the single, static orthodontic data of traditional fixed bracket cores into a multi-functional, replaceable module. The switching of orthodontic data is achieved through the plugging and unplugging of physical modules, greatly improving the flexibility and convenience of clinical orthodontic plans. Furthermore, the bracket core 220 is pre-loaded with archwire channel data for different orthodontic systems. In this embodiment, it includes at least: Roth system data core, MBT system data core, Damon system high torque core, Damon system normal torque core, and Damon system low torque core. Orthodontists can insert the corresponding bracket core 220 (such as the MBT core) into the bracket slot 210 body before or during treatment, according to the needs of different stages of treatment or the characteristics of the case. When the treatment plan needs to be adjusted, there is no need to remove the bracket slot 210. The old bracket core 220 can be pulled out with a special clamping tool 300 and replaced with a new bracket core 220. The directional low-friction buccal tube is specifically designed for bonding to anchorage molars where movement needs to be controlled, and is used to connect various devices, including archwires, rubber bands, etc. The directional low-friction buccal tube includes a first molar directional low-friction buccal tube and a second molar directional low-friction buccal tube; see reference. Figure 4 In section a, the overall shape of the directional low-friction buccal tube is shown. The directional low-friction buccal tube includes a second bonding base plate 230, a lumen 231, and a one-way resistance mechanism 232. The second bonding base plate 230 is used for bonding to the buccal surface of the molar, and the lumen 231 is used for inserting the orthodontic archwire. A groove 233 is formed on the lumen 231. (Refer to...) Figure 4 In sections b and c, the unidirectional resistance mechanism 232 includes components disposed on the gingival wall or... The wall has a one-way ball bearing 2321 and a limiting structure 234 disposed in a groove 233. The one-way ball bearing 2321 is partially housed in the groove 233 and can rotate. The surface of the one-way ball bearing 2321 protrudes from the cavity 231 to contact the bowwire. The limiting structure 234 is used to restrict the one-way ball bearing 2321 to rotate in only one direction. Further, a specific embodiment of the limiting structure 234 is an asymmetrical ratchet structure in the prior art, and is equipped with a spring to provide pressure.

[0038] Furthermore, the directional low-friction buccal tube is divided into two types: mesial-moving directional low-friction buccal tube and distal-moving directional low-friction buccal tube; The mesial movement directional low-friction buccal tube is suitable for situations where molars need to be pulled mesially forward. The mesial movement directional low-friction buccal tube is divided into a right mesial movement directional low-friction buccal tube and a left mesial movement directional low-friction buccal tube. For the right mesial movement directional low-friction buccal tube, its limiting structure 234 is configured to allow only the unidirectional ball 2321 to rotate clockwise. When the molar moves mesially, the ball rolls, and the friction is almost zero. When subjected to distal force, the ball locks, generating high friction. For the left mesial movement directional low-friction buccal tube, its limiting structure 234 is configured to allow only the unidirectional ball 2321 to rotate counterclockwise.

[0039] The distal movement directional low-friction buccal tube is suitable for situations where molars need to be pushed distally and posterolaterally, and its principle is the opposite of that of the mesial movement type. For the right distal movement directional low-friction buccal tube, the limiting structure 234 only allows the ball to rotate counterclockwise; for the left distal movement low-friction buccal tube, the limiting structure 234 only allows the ball to rotate clockwise.

[0040] Reference Figure 5 The special clamping tool 300 is a specially designed metal rod with one side being single-headed and the other side being double-headed. It includes a first end 301 and two rod parts 304 integrally connected to the first end. Each rod part 304 has a second end 302 at its other end. The first end 301 is a single-headed flat shape, used to insert into and move the sliding cover-type latch on the bracket slot 210 to achieve opening and closing. The second end 302 is a double-headed structure with a tapered front end and a groove, specifically used to insert into the round hole 226 of the bracket core 220 for clamping. The special clamping tool 300 has a spring mechanism 303 in the middle. In this embodiment, the spring mechanism 303 is specifically a torsion spring structure, which is installed at the hinge axis of the two rod parts 304. Its structure and working principle are similar to common medical tweezers, providing continuous clamping force for the hinged double-headed ends, making the operation more effortless and precise.

Each layer is strictly divided according to tooth position and type, and has clear markings that correspond one-to-one with the positioning information displayed on the touch screen 104 of the artificial intelligence host 100, ensuring that doctors can find the required components instantly.

[0042] Example 2 The method of using the switchable orthodontic system described in Example 1 includes the following steps: Reference Figure 7 Step 1, Initial assembly and bonding steps: Step a: The doctor turns on the artificial intelligence host 100 and inputs the patient's basic information and treatment needs through the voice recognition system 101; Step b: After the chip 102 of the artificial intelligence host 100 processes the patient's basic information and orthodontic needs received by the voice recognition system 101, it outputs a personalized orthodontic system recommendation plan through the voice output system 103 and the touch display screen 104, and displays the position of each tooth bracket core 220 in the storage device 400. Step c: Based on the recommended plan output by the voice output system 103 and the touch display screen 104, the doctor takes out the bracket slot 210 and bracket core 220 of the required tooth position from the corresponding position of the storage device 400. Step d: Use the second end 302 of the special clamping tool 300 to clamp the bracket core 220 and the gingival wing 224.
