Description

Technical Field

[0001] This application belongs to the technical field of oral functional orthodontic devices, specifically relating to a rotating mandibular double chin pad magnetic orthodontic appliance. Background Technology

[0002] During childhood growth and development, malocclusion caused by congenital genetic factors and acquired environmental factors not only impairs appearance but also affects chewing, swallowing, speech, and facial expression. The incidence of malocclusion is on the rise in modern society. Currently, orthodontic appliances that utilize the strength of the orofacial muscles as traction are widely accepted and used clinically by both patients and doctors. Furthermore, current research on the responses of the condyle, jawbone, and alveolar bone to the magnetic Twin.block appliance has confirmed that this type of appliance significantly improves mandibular development during the mixed dentition period and early permanent dentition, corrects sagittal skeletal misalignment, and significantly improves facial profile.

[0003] However, while traditional or existing magnetic twin-block appliances can effectively improve low-angle and even-angle mandibular retrusion, they are weak in guiding and controlling the clockwise rotational growth of the mandible. Simultaneously, they are ineffective in inhibiting clockwise mandibular rotation and guiding counterclockwise growth, making them particularly disadvantageous for high-angle cases. Furthermore, existing bimaxillary pad appliances can elongate posterior teeth but cannot intrude them. They also lack control over the vertical eruption of anterior teeth, failing to effectively elongate and intrude them, or control anterior tooth growth height and overbite.

[0004] Against this backdrop, this application proposes a novel magnetically guided and functional double-chin pad appliance—the "rotating mandible" type double-chin pad magnetic appliance—based on improvements to the traditional double-chin pad appliance. This appliance is designed to address common malocclusions caused by imbalances in the sagittal and vertical relationships of the maxilla and mandible, and can effectively guide and control the clockwise and counterclockwise rotational growth of the mandible. Utility Model Content

[0005] The purpose of this application is to provide a rotating mandibular double-pawl magnetic orthodontic appliance that improves upon the shortcomings of existing double-pawl appliances, such as "their guiding and control forces in the clockwise rotational growth direction of the mandible are weak, and they are almost powerless in inhibiting the clockwise rotation of the mandible and guiding its counterclockwise rotational growth, thus being very unfavorable for high-angle cases. Furthermore, existing double-pawl appliances can elongate posterior teeth but cannot indent them. At the same time, their control over the vertical eruption of anterior teeth is also lacking, and they cannot control or improve problems such as abnormal vertical eruption height of anterior teeth." Traditional double-pawl appliances also have drawbacks in clinical use, such as instability of the mandibular position during normal wear and sleep, insufficient perioral traction, and reluctance to wear the extraoral traction device due to its impact on daily life.

[0006] Therefore, this application provides a technique that introduces magnetic force into the bimaxillary appliance and opposing natural teeth. Utilizing the attractive or repulsive force of magnets as the source of corrective force, and in conjunction with the installation of magnets on the corresponding opposing teeth, it achieves jawbone repositioning and remodeling, as well as controlling the vertical eruption of anterior and posterior teeth. This allows for vector-based control of the corrective force in both the anteroposterior and vertical directions, resolving common malocclusions caused by imbalances in the sagittal and vertical relationships of the maxilla and mandible. In particular, it can effectively guide and control the clockwise and counterclockwise rotational growth of the mandible, achieving guided control of its clockwise or counterclockwise rotational growth. Simultaneously, the synergistic effect of the biological effects of the magnetic field and external traction stimulates faster proliferation of condylar cells, thereby shortening the treatment duration.

[0007] The objective of this application is achieved through the following technical solution:

[0008] A rotating mandibular double-pawl magnetic orthodontic appliance includes a first pawl and a second pawl opposite to the first pawl. A first inclined guide plate facing forward is formed on the posterior pawl portion of the first pawl, and a second inclined guide plate facing backward is formed on the anterior pawl portion of the second pawl. The first inclined guide plate and the second inclined guide plate are opposite to each other. A pawl gap is reserved in the posterior pawl portion of the first pawl. The appliance also includes magnets on the first and second anterior teeth that are opposite to each other and magnetically attracted or repelled. Magnets that are opposite to each other and magnetically attracted are provided on the first and second inclined guide plates. The magnets on the occlusal surface or incisal edge of the first pawl and the magnets on the occlusal surface or incisal edge of the opposing teeth are opposite to each other and magnetically attracted or repelled.

[0009] Furthermore, the magnets on the first and second anterior teeth are arranged along the occlusal plane, the magnets on the first and second inclined guide plates are arranged along the occlusal incline, and the magnets on the occlusal surface or incisal edge of the first occlusal pad and the magnets on the occlusal surface or incisal edge of the opposing tooth are arranged along the occlusal plane.

[0010] Furthermore, the first jaw pad is either a maxillary pad or a mandibular pad, and the corresponding second jaw pad is either a mandibular pad or a maxillary pad.

[0011] Furthermore, the first and second jaw pads are made of transparent rigid material.

[0012] Furthermore, the first jaw pad includes a first anterior tooth fixation piece with an integral structure, and the second jaw pad includes a second anterior tooth fixation piece with an integral structure. The first anterior tooth fixation piece and the second anterior tooth fixation piece are provided with magnets that are positioned opposite each other and are magnetically attracted or repelled.

[0013] Furthermore, the first and second anterior tooth fasteners are planar guide plates, and the magnets on the first and second anterior tooth fasteners are arranged parallel to the guide plate surface.

[0014] Furthermore, the rear support pad portion of the first jaw pad has a support pad gap of 3-5 cm.

[0015] Furthermore, the first inclined guide plate is inclined from front to back from the crown to the root, and the corresponding second inclined guide plate is inclined from back to front from the crown to the root.

[0016] Furthermore, the magnets on the first and second inclined guide plates are arranged parallel to the guide plate surfaces.

[0017] Furthermore, the first and second jaw pads are provided with retainers, which are clips, loops, or interproximal hook structures.

[0018] Furthermore, the magnet is a rare-earth permanent magnet, specifically a neodymium iron boron high-power magnet.

[0019] Furthermore, the surface of the magnet is coated with a titanium nitride film.

[0020] Furthermore, the magnet can be rectangular, rhomboid, circular, tooth-fitting, or accessory-fitting.

[0021] Furthermore, the magnet is fixed to the jaw pad by embedding, bonding, or sleeve embedding, and the magnet is a removable or fixed pre-formed crown or a customized crown structure.

[0022] Furthermore, this also includes the bicornuate lip arch located in a single or double jaw.

[0023] The beneficial effects of this application are as follows: Magnetic force is introduced into the bimaxillary splint appliance and the corresponding opposing natural teeth. Utilizing the attractive or repulsive force of the magnets as the source of corrective force, and in conjunction with the installation of magnets on the opposing teeth, the jawbone is repositioned and remodeled, and the vertical eruption of posterior teeth is controlled, optimizing and improving the jaw curve. This allows for vector-based control of the corrective force in both the anteroposterior and vertical directions, resolving common malocclusions caused by imbalances in the sagittal and vertical relationships of the maxilla and mandible. In particular, it effectively guides and controls the clockwise and counterclockwise rotational growth of the mandible, achieving guided control of this growth. Simultaneously, the synergistic effect of the biological effects of the magnetic field and external traction stimulates faster proliferation of condylar cells, shortening the treatment duration. Furthermore, this application has the advantages of simple structure, small size, easy fabrication, strong and lasting corrective force, minimal impact on oral function, and minimal foreign body sensation for patients.

[0032] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0033] Example 0

[0034] refer to Figure 1 and Figure 2 As shown, a rotating mandibular double occlusal pad magnetic orthodontic appliance includes a first occlusal pad 1, a first inclined guide plate 3, a second occlusal pad 4, a second inclined guide plate 6, a double-curved labial arch 7, a retainer 8, and a magnet 9. It may also include a first anterior tooth fixation element 2 and a second anterior tooth fixation element 5.

[0035] The first occlusal pad 1 and the second occlusal pad 4 are two opposing occlusal pads, that is, the first occlusal pad 1 is either a maxillary pad or a mandibular pad, and the corresponding second occlusal pad 4 is either a mandibular pad or a maxillary pad. The first occlusal pad 1 and the second occlusal pad 4 are a modified double occlusal pad orthodontic appliance, made of transparent rigid material, and are custom-made according to the patient's mouth shape and tooth position, as well as the arrangement, shape and size of the teeth.

[0036] The first occlusal pad 1 has a forward-facing first inclined guide plate 3 formed on its posterior support portion, and the second occlusal pad 4 has a rearward-facing second inclined guide plate 6 formed on its anterior support portion. The first inclined guide plate 3 and the second inclined guide plate 6 are opposite to each other. The posterior support portion of the first occlusal pad 1 has a reserved support gap to ensure that the posterior occlusal pad does not contact the opposing tooth.

[0037] It also includes magnets 9 on the first and second anterior teeth that are opposite each other and magnetically attracted or repelled. The first inclined guide plate 3 and the second inclined guide plate 6 are provided with magnets 9 that are opposite each other and magnetically attracted. The magnets 9 on the occlusal surface or incisal edge of the first jaw pad 1 are opposite each other and magnetically attracted or repelled.

[0038] When the upper and lower posterior teeth are in the reconstructed occlusal position, the positive and negative poles of the magnets are opposite each other, using the resulting attraction to force the mandible into the reconstructed posture. Simultaneously, magnets of the same or opposite poles are placed on the occlusal surfaces of the posterior tooth pads and the opposing teeth. Through magnetic orthodontic force, the posterior teeth are vertically indented or elongated, improving the mandibular plane angle and guiding and controlling the clockwise or counterclockwise rotational growth of the mandible. Magnets of the same or opposite poles are placed on the anterior teeth or on the natural anterior teeth. Using the magnetic attraction or repulsion of the magnets, the anterior teeth are vertically elongated or indented, achieving the goal of controlling the vertical eruption height of the anterior teeth and optimizing and improving the occlusal curve.

[0039] Simultaneously, the synergistic effect of the biological effects of the magnetic field and the external traction stimulates condylar cells to proliferate more rapidly, thereby shortening the treatment course. Furthermore, utilizing the principle of attraction and repulsion between magnets, different types of malocclusion formed during mandibular bone growth can be flexibly adjusted according to the actual situation. This is achieved by modifying the number, placement, orientation, and combination of like poles and unlike poles of the magnets, thus controlling the corrective force in both the anterior-posterior and vertical directions, guiding and controlling the clockwise or counterclockwise rotational growth of the mandible.

[0040] Magnets 9 on the first inclined guide plate 3 and the second inclined guide plate 6 are arranged along the jaw slope. Specifically, the first inclined guide plate 3 is inclined from front to back from the crown to the root, and the second inclined guide plate 6 is inclined from back to front from the crown to the root. The magnets 9 on the first inclined guide plate 3 and the second inclined guide plate 6 are arranged parallel to the guide plate surface. High-power permanent magnets with opposite poles are placed on the upper and lower jaw pad inclined guide plates, so that when the upper and lower posterior teeth are in the reconstructed position, the positive and negative poles of the magnets are opposite, and the resulting attractive force compels the mandible into the reconstructed position.

[0041] The first occlusal pad 1 includes a first anterior tooth fixture 2 with an integral structure, and the second occlusal pad 4 includes a second anterior tooth fixture 5 with an integral structure. The first anterior tooth fixture 2 and the second anterior tooth fixture 5 are provided with magnets 9 that are positioned opposite each other and are magnetically attracted or repelled. That is, the magnets 9 on the first and second anterior teeth are mounted on the anterior tooth fixtures, forming an integral structure with the occlusal pads. Similarly, the magnets 9 on the first and second anterior teeth can also be mounted independently of the occlusal pads, directly on the natural anterior teeth.

[0042] Magnets 9 on the first and second anterior teeth are arranged along the occlusal plane. Specifically, the first anterior tooth fixture 2 and the second anterior tooth fixture 5 are planar guide plates, and the magnets 9 on the first and second anterior tooth fixtures 2 and 5 are arranged parallel to the guide plate surface. One or more sets of magnets with the same or opposite poles are placed parallel to the upper and lower anterior teeth and the opposing anterior teeth. By utilizing the magnetic force of attraction and repulsion between the magnets, the anterior teeth are vertically elongated or depressed, and the same principle is used to control the vertical eruption height of the anterior teeth, so as to improve the overbite and overjet relationship of the anterior teeth and optimize the occlusal curve.

[0043] The magnets 9 on the occlusal surface or incisal edge of the first occlusal pad 1 and the magnets 9 on the occlusal surface or incisal edge of the opposing tooth are arranged along the occlusal plane. One or more sets of magnets of the same or opposite poles are placed parallel to each other on the occlusal surface of the occlusal pads in the maxillary and mandibular posterior tooth regions, and on the occlusal surface of the corresponding opposing tooth. Utilizing the magnetic forces of attraction and repulsion between the magnets, the posterior teeth are vertically elongated or depressed, and the same principle is used to control the vertical eruption height of the posterior teeth, thereby improving and optimizing the occlusal curve and guiding and controlling the clockwise or counterclockwise rotational growth of the mandible. The posterior bolster of the first occlusal pad 1 has a bolster gap of 3–5 cm to ensure that the posterior occlusal pad does not contact the opposing tooth.

[0044] The first jaw pad 1 and the second jaw pad 4 are provided with retainers 8. The retainers of the upper and lower jaw pads can be scissor clips, ring clips or interproximal hook structures according to the shape of the abutment teeth and the eruption status. The number and position of these retainers depend on the specific situation of the oral cavity.

[0045] One or more sets of symmetrical or asymmetrical magnets are placed on the anterior and posterior occlusal pads or natural teeth. Magnet 9 is a third-generation rare-earth permanent magnet, neodymium iron boron (NdFeB), with a titanium nitride film coating its surface. NdFeB contains iron, which is particularly susceptible to oxidation, corrosion, and even disintegration in the oral cavity environment, leading to a decline in magnet performance. By uniformly coating the magnet surface with a titanium nitride film, the chemical stability and high film hardness of titanium nitride are achieved, resulting in wear and corrosion resistance.

[0046] Depending on specific needs, the magnet 9 can be rectangular, rhomboid, circular, or fitted with accessories. The magnet 9 can be fixed to the occlusal pad by embedding, bonding, or sleeve mounting, or it can be a removable or fixed pre-formed crown or a custom-made crown structure, allowing the magnet 9 to be directly placed on the natural tooth. The orientation of the magnet 9 can be changed, and the direction of the magnetic force can be set according to specific needs.

[0047] Depending on the specific situation, a double-curved labial arch 7 can be used for single- or double-jaw expansion by placing a spiral expander in the upper and lower jaws. This application has the advantages of simple structure, small size, easy fabrication, strong and lasting corrective force, minimal impact on oral function, and minimal foreign body sensation for patients when worn in the mouth.

[0048] Example 1

[0049] refer to Figure 3 As shown, a rotating mandibular double-pad magnetic appliance is used to guide the mandible forward in patients with mandibular retrusion and low angle. Bilateral maxillary and mandibular pad inclined guides have a pair of magnets of opposite polarities placed parallel to each other along the inclined slope. When the mandible protrudes to the reconstructed position, the positive and negative poles of the magnets on the anterior and posterior teeth are opposite, using the resulting attraction to force the mandible into the reconstructed posture. A 3-5mm space is reserved between the maxillary posterior pad and the occlusal surface of the mandibular posterior teeth. Two pairs of magnets of opposite polarities are placed on the occlusal surfaces of the maxillary and mandibular posterior teeth respectively, using attraction to elongate the maxillary and mandibular posterior teeth. Simultaneously, multiple sets of magnets of the same polarity are placed on the mandibular pad anterior component and the maxillary pad anterior component, using repulsive force to depress the anterior teeth. Through the combined orthodontic forces described above, the following are achieved: 1. Inhibiting maxillary growth and promoting mandibular growth; 2. Elongating posterior teeth and depressing anterior teeth. This improves the occlusal curve and the growth direction of the mandible, promoting mandibular protrusion and clockwise rotation.

[0050] Example 2

[0051] refer to Figure 4As shown, a rotating mandibular double-pad magnetic appliance is used to guide the mandible forward in patients with high-angle mandibular retrusion. Bilateral maxillary and mandibular posterior pads are arranged with inclined guide plates, and a pair of magnets of opposite polarities are placed parallel to each other along the inclined slope. When the mandible protrudes to the reconstructed position, the positive and negative poles of the magnets are opposite each other, using the resulting attraction to force the mandible into the reconstructed posture. A 3-5mm space is reserved between the maxillary posterior pads and the occlusal surfaces of the mandibular posterior teeth. Two pairs of magnets of the same polarity are placed on the occlusal surfaces of both the maxillary and mandibular posterior pads, using repulsive force to indent the maxillary and mandibular posterior teeth. Simultaneously, multiple sets of magnets of the same polarity are placed on the mandibular and maxillary anterior pad fixtures, using repulsive force to indent the anterior teeth. Through the combined orthodontic forces described above, the following effects are achieved: 1. Inhibiting maxillary growth and promoting mandibular growth; 2. Indenting posterior teeth and indenting anterior teeth. This improves the occlusal curve and the growth direction of the mandible, promoting mandibular protrusion and counterclockwise rotation.

[0052] Example 3

[0053] refer to Figure 5 As shown, a rotating mandibular double-pad magnetic appliance is used for patients with functional Angle Class III low-angle conditions where the maxilla is normally developed and the mandible can be retracted to a "cut-to-cut" position. Bilateral maxillary and mandibular pad inclined guides are used, with a pair of magnets of opposite polarities placed parallel to each other along the inclined guide slope. When the mandible is retracted to the reconstructed position, the positive and negative poles of the magnets on the anterior and posterior teeth are opposite, using the resulting attraction to force the mandible into the reconstructed position. A 3-5mm space is reserved between the mandibular posterior pad and the occlusal surface of the maxillary posterior teeth. Two pairs of magnets of opposite polarities are placed on the occlusal surfaces of both the mandibular and maxillary posterior teeth, respectively, to elongate the posterior teeth through attraction. Simultaneously, multiple sets of magnets of the same polarity are placed on the anterior teeth fasteners of the maxillary and mandibular posterior teeth, using repulsive force to depress the anterior teeth. Through the combined orthodontic forces described above, the following effects are achieved: 1. Inhibiting maxillary growth and promoting mandibular growth; 2. Elongating posterior teeth and depressing anterior teeth. This improves the occlusal curve and the growth direction of the mandible, promotes mandibular retraction and clockwise rotation, and improves the overbite and overjet relationship of the anterior teeth.

[0054] Example 4

[0055] refer to Figure 6As shown, a rotating mandibular double-pad magnetic appliance is used for high-angle patients with normal maxillary development and a mandibular retraction to a functional Angle Class III position. Bilateral maxillary and mandibular pad inclined guides are used, with a pair of magnets of opposite polarities placed parallel to each other along the inclined guide slope. When the mandible retracts to the reconstructed position, the positive and negative poles of the magnets on the anterior and posterior teeth are opposite, using the resulting attraction to force the mandible into the reconstructed position. A 3-5mm space is reserved between the mandibular posterior pad and the occlusal surface of the maxillary posterior teeth. Two pairs of magnets of the same polarity are placed on the occlusal surfaces of the mandibular posterior pad and the maxillary posterior teeth, respectively, using repulsive force to indent the maxillary and mandibular posterior teeth. Simultaneously, multiple sets of magnets of opposite polarities are placed on the anterior components of the maxillary pad and the mandibular anterior components, using attraction to elongate the anterior teeth. Through the combined orthodontic forces described above, the following effects are achieved: 1. Inhibiting maxillary growth and promoting mandibular growth; 2. Indenting posterior teeth and elongating anterior teeth. This improves the occlusal curve and the growth direction of the mandible, promotes mandibular retraction and counterclockwise rotation, and improves the overbite and overjet relationship of the anterior teeth.
