Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a combined orthodontic appliance that efficiently depresses anterior teeth and controls torque. Background Technology

[0002] In recent years, clear aligner technology has gradually developed, gaining popularity among patients due to its advantages such as personalization, aesthetics, ease of cleaning, and fewer follow-up visits. Its unique characteristics compared to fixed orthodontic treatment lie in its pushing force on teeth and the tooth movement achieved through attachments. Fixed orthodontic techniques achieve tooth movement through brackets and wires, offering superior control over anterior tooth torque and efficient control over anterior tooth retraction compared to clear aligners. Fixed orthodontic treatment often requires a longer treatment course and high patient cooperation to achieve the treatment goals. Therefore, the advantages of clear aligners and fixed orthodontic techniques can be combined to design a "hybrid treatment" approach, simultaneously meeting the needs of aesthetics and efficiency. This approach maintains the structural integrity of the clear aligners while incorporating archwires with the force-applying characteristics of fixed orthodontics, effectively integrating the two. As treatment progresses, the patient's teeth shift, requiring adjustments to the force exerted by the archwire. This is particularly important for patients who have undergone tooth extraction, as the extraction space closes, the dental arch length decreases, and the force exerted by the archwire on the teeth changes significantly. In this technique, the doctor needs to bend and adjust the archwire to achieve the desired force on the teeth. The operation is so complex that it cannot be done by the patient on their own. In particular, the archwire needs to be adjusted multiple times during the treatment process, which causes great inconvenience to the patient. Utility Model Content

[0003] This invention provides an improved combination orthodontic appliance that efficiently depresses anterior teeth and controls torque, addressing the problem of complex archwire adjustment in existing technologies and reducing the difficulty of archwire adjustment.

[0004] To achieve the above objectives, this utility model provides a combined orthodontic appliance for efficient anterior tooth intrusion and torque control, comprising: The buccal tube includes a base plate and a fixing tube. The fixing tube is rotatably connected to the base plate, and the direction of rotation is perpendicular to the direction of its own axis. The angle between the axis of the fixing tube and the occlusal plane is greater than 0° and less than 90°, with the mesial side facing the gingiva and the distal side facing the crown. A bracketless orthodontic appliance, comprising an anterior region and a posterior region, wherein the posterior region is located on both sides of the anterior region in the distal direction and is positioned corresponding to the base plate; An archwire fixing device, comprising a first fixing member and a second fixing member, wherein the first fixing member is disposed corresponding to the anterior tooth region, and the second fixing member is detachably connected to the first fixing member; The occlusal plane is the plane formed when the upper and lower teeth bite together. In use of this novel combined orthodontic appliance with high efficiency intrusion of anterior teeth and torque control, the bracketless appliance is worn on the patient's maxillary teeth. The base plate is fixed to the buccal surface of the posterior region of the bracketless appliance or the buccal surface of the patient's posterior teeth. The end of the archwire is inserted into the fixing tube of the buccal tube. The portion of the archwire in the anterior region should be positioned in the gingival direction of the patient's anterior teeth and 5-10 mm from the cervical region of the crown to provide labial torque and intrusion force to the anterior teeth, assisting in the correction of deep overbite or preventing anterior tooth elongation and lingual tilting, as well as mesial tilting of posterior teeth, during anterior tooth retraction after tooth extraction. Subsequently, the second fixing member is connected to the first fixing member to position the archwire, at which point the portion of the archwire in the anterior region is flush with the cervical region of the crown. Because the fixing tube is tilted, the archwire, after being connected to the first fixing member, can continuously apply force to the anterior teeth. This force has a depressing and labial tilting effect on the anterior teeth, and an elongating and distal tilting effect on the posterior teeth. This prevents the teeth on both sides from tilting towards the extraction space during the retraction of the extraction space, thereby achieving tooth movement towards the target position. As the orthodontic process progresses, the patient's teeth shift, especially for patients who have undergone extractions. When the extraction space closes and the dental arch length decreases, the magnitude of the force exerted by the archwire on the anterior teeth changes. At this time, the magnitude of the force exerted by the archwire on the anterior teeth can be adjusted simply by adjusting the tilt angle of the fixing tube, making the operation relatively simple.

[0005] As an optional technical solution, one end of the fixing tube is hinged to the base plate, and the other end is provided with a first fixing structure. On the base plate, corresponding to the first fixing structure, multiple second fixing structures are provided, spaced apart along the rotation trajectory of the first fixing structure. The second fixing structures are used to cooperate with the first fixing structure. The cooperation of the first fixing structure and the second fixing structure can fix the fixing tube relative to the base plate, thereby stabilizing the force exerted by the archwire on the anterior teeth. The cooperation of the first fixing structure with one of the pre-set second fixing structures facilitates the rapid configuration of the tilt angle of the fixing tube relative to the occlusal plane.

[0006] As an optional technical solution, the number of the second fixing structures is three, and the line connecting each second fixing structure to the hinge point between the fixing tube and the base plate forms an angle of 15°, 30° and 45° with the occlusal plane, respectively.

[0007] As an optional technical solution, the second fixing member includes a connecting part, a first fixing part, and a second fixing part connected in sequence. The connecting part is used to connect the archwire. The first fixing part and the second fixing part are annular, and the first fixing part and the second fixing part are internally connected. The diameter of the connecting part is smaller than the inner diameter of the second fixing part, and the inner diameter of the first fixing part is larger than the inner diameter of the second fixing part. The second fixing part is used to cooperate with the first fixing member. In this invention, after the high-efficiency anterior tooth intrusion and torque-controlled combined orthodontic appliance is installed on the patient's maxillary teeth, the archwire needs to be pulled towards the first fixing member and fixed relative to it. Due to the limited operating space, the operation is difficult. Therefore, the first fixing part with a larger inner diameter can be first fitted onto the outer periphery of the first fixing member. Under the action of the archwire's own elasticity, the first fixing part and the second fixing part slide relative to the first fixing member towards the archwire and the patient's gingiva. The first fixing member passes through the connecting part between the first fixing part and the second fixing part and finally cooperates with the second fixing part, thereby reducing the difficulty of fixing the archwire relative to the first fixing member.

[0008] As an optional technical solution, the second fixing member includes a traction hook and an elastic member. The traction hook is used to connect the bow wire, and one end of the elastic member is connected to the traction hook and the other end is connected to the first fixing member.

[0009] As an optional technical solution, the buccal tube is disposed on the buccal side of the first molar of the bracketless orthodontic appliance; the first fixing member is disposed in the middle of the crown of the lateral incisor of the bracketless orthodontic appliance.

[0010] As an optional technical solution, the first fixing member is bonded, welded, or integrally formed onto the bracketless orthodontic appliance with the buccal tube.

[0011] As an optional technical solution, the axial length of the buccal tube is 7-12 mm. Since the force exerted by the archwire on the anterior teeth relies on the buccal tube's fixation of the archwire end, using a longer buccal tube helps prevent the archwire from slipping out of the buccal tube.

[0012] As an optional technical solution, the bracketless brace, the first fixation member, and the buccal tube are made of transparent plastic.

[0013] One or more technical solutions provided by this utility model have at least the following technical effects or advantages: This invention relates to a combined orthodontic appliance that efficiently indents anterior teeth and controls torque. The buccal tube, used to fix the end of the archwire, is rotatably connected to the base plate to change its angle relative to the occlusal plane. The base plate is fixed to the buccal surface of the posterior teeth or the buccal surface of the patient's posterior teeth in the bracketless orthodontic appliance. The archwire is then fixed in the middle by first and second fixing members corresponding to the anterior teeth. As treatment progresses, the patient's teeth shift, and the force exerted by the archwire on the anterior teeth changes. At this point, simply adjusting the angle of the fixing tube relative to the occlusal plane adjusts the force exerted by the archwire on the anterior teeth, maintaining indentation and torque control during treatment. The operation is relatively simple. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In this invention, the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0018] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0019] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a direct connection, an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0020] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0021] During orthodontic treatment, three-dimensional control of teeth is required to align and level the dentition, improve occlusion, and ultimately enhance oral and maxillofacial health and aesthetics. In the anterior region, which is closely related to facial aesthetics, possible malocclusions include, but are not limited to, lingual inclination of anterior teeth, anterior tooth elongation, deep overbite, deep overjet, and double overjet, which can affect occlusion, cause mandibular tooth wear, restrict sagittal mandibular development, and impact aesthetics. Targeted procedures involved in orthodontic treatment include, but are not limited to, controlling anterior tooth torque, i.e., controlling the labial (buccal) and lingual inclination of teeth, retracting anterior teeth, and intruding anterior teeth, to establish normal overbite and overjet occlusion.

[0022] In recent years, clear aligner technology has gradually developed, gaining popularity among patients due to its advantages such as personalization, aesthetics, ease of cleaning, and fewer follow-up visits. Its unique characteristics compared to fixed orthodontic treatment include the force exerted on the teeth and the tooth movement achieved through attachments. Fixed orthodontic techniques achieve tooth movement through brackets and wires, offering superior control over anterior tooth torque and efficient control over anterior tooth retraction compared to clear aligners. Fixed orthodontic treatment often requires a longer treatment period and higher patient cooperation to achieve the desired results. Therefore, a "hybrid treatment" approach can be designed, combining the advantages of clear aligners and fixed orthodontic techniques to meet both aesthetic and efficiency needs. This approach integrates the structural integrity of the clear aligners with the force-applying characteristics of fixed orthodontics. This requires considering not only the compact design of the device within the mouth but also its ease of use, allowing patients to avoid frequent wire removal when using the same set of clear aligners and quickly securing the wire to the clear aligners when changing to the next set. This necessitates a simplified device design.

[0023] Based on this, this invention provides a combined orthodontic appliance that efficiently indents the anterior teeth and controls torque. The buccal tube, used to fix the end of the archwire, is rotatably connected to the base plate to change its angle relative to the occlusal plane. The base plate is installed on the posterior tooth area of ​​the bracketless orthodontic appliance or on the surface of the patient's posterior teeth. The archwire is fixed in the middle by first and second fixing members corresponding to the anterior tooth area. As the orthodontic process progresses, the patient's teeth shift, and the force exerted by the archwire on the anterior teeth changes. At this point, simply adjusting the angle of the fixing tube relative to the occlusal plane adjusts the force exerted by the archwire on the anterior teeth, maintaining the indentation effect and torque control of the anterior teeth during treatment. The operation is relatively simple.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] Example 1

[0026] like Figure 1 , Figure 2 as well as Figure 6 As shown, where Figure 1 The black dashed line indicates the state before the archwire 4 is fixed relative to the first fixation member 3. This embodiment provides a combined orthodontic appliance with efficient anterior tooth intrusion and torque control, including a bracketless appliance 1, a buccal tube 2, an archwire fixation device, and an archwire 4. The bracketless appliance 1 includes an anterior tooth region 11 and a posterior tooth region 12. The posterior tooth regions 12 are located on both sides of the anterior tooth region 11 in the distal direction, and the two posterior tooth regions 12 are arranged opposite each other. The buccal tube 2 includes a base plate 22 and a fixation tube 21. The base plate 22 is located on the buccal side of the posterior tooth region 12 or installed on the buccal tooth surface 300 of the patient's posterior teeth. The fixation tube 21 is rotatably connected to the base plate 22, and the axis of rotation is parallel to the axial direction of the fixation tube 21. The end of the archwire 4 passes through the fixation tube 21. The angle β between the axis of the fixation tube 21 and the occlusal plane 100 is greater than 0° and less than 90°, and the mesial side faces the gingiva 200 and the distal side faces the crown. The archwire fixation device includes a first fixation member 3 and a second fixation member 5. The first fixation member 3 is located in the anterior tooth region 11 or on the labial side of the patient's anterior teeth. The end of the archwire 4 passes through the buccal tube 2, and the second fixation member 5 is provided on the archwire 4. The second fixation member 5 is detachably connected to the first fixation member 3. The occlusal plane 100 is the plane formed when the upper and lower teeth bite together.

[0027] In this embodiment, the combined orthodontic appliance for efficient anterior tooth intrusion and torque control is used by placing the bracketless appliance 1 on the patient's maxillary teeth. The base plate 22 is fixed to the posterior tooth region or the tooth surface 300 of the patient's posterior teeth. The end of the archwire 4 is inserted into the fixing tube 21 of the buccal tube 2. The portion of the archwire 4 located in the anterior tooth region 11 should be positioned in the direction of the gingiva 200 of the patient's anterior teeth and 5-10 mm away from the cervical region of the crown to provide labial torque and intrusion force to the anterior teeth, assisting in the correction of deep overbite or preventing anterior tooth elongation and lingual tilting during anterior tooth retraction after tooth extraction. Subsequently, the second fixing member 5 is connected to the first fixing member 3 to position the archwire 4. At this time, the portion of the archwire 4 located in the anterior tooth region 11 is flush with the cervical region of the crown. Because the fixed tube 21 is tilted, the archwire 4, after being connected to the first fixing member 3, can continuously apply force to the anterior teeth. This force has an indentation and labial tilting effect on the anterior teeth, and an elongation and distal tilting effect on the posterior teeth, preventing the teeth on both sides from tilting towards the extraction space during the retraction of the extraction space, thereby achieving orthodontic treatment. As the orthodontic process progresses, the patient's teeth shift, especially for patients who have undergone extractions. The extraction space closes, the dental arch length decreases, and the magnitude of the force exerted by the archwire 4 on the anterior teeth changes. At this time, only the tilt angle of the fixed tube 21 needs to be adjusted to adjust the magnitude of the force exerted by the archwire 4 on the anterior teeth, maintaining the indentation effect and torque control on the anterior teeth during the orthodontic process, making the operation relatively convenient. Furthermore, as the orthodontic process progresses, the tilt angle β of the fixed tube 21 relative to the occlusal plane should gradually decrease from large to adapt to the progress of indentation of the anterior teeth. In addition, when the base plate 22 is set on the bracketless appliance 1, the patient can remove and wear the bracketless appliance 1 together with the archwire 4 without having to do it in separate steps. When replacing the bracketless orthodontic appliance 1 according to the steps, the patient can load the archwire 4 onto the bracketless orthodontic appliance 1 either outside or inside the mouth.

[0028] Specifically, such as Figure 5 As shown ( Figure 5 The blue dashed line represents the state when the archwire is not connected to the first fixation member. After the archwire is connected to the first fixation member via the second fixation member, it can generate a depressing force F1 on the anterior teeth. Since the point of application of the depressing force F1 is located on the labial side of the center of resistance in the anterior teeth, it will generate a labial torque M1 on the anterior teeth, causing the anterior teeth to depress and labially tilt. At the same time, it can generate an elongating force F2 on the posterior teeth. The point of application of the elongating force F2 is located mesially on the center of resistance in the posterior teeth, thus generating a distal torque M2 on the posterior teeth, causing the posterior teeth to tilt distally. Therefore, the combined orthodontic appliance with efficient anterior tooth depressing and torque control in this embodiment can prevent the teeth on both sides from tilting towards the extraction space during the retraction of the extraction space, thereby efficiently depressing the anterior teeth and controlling torque.

[0029] Among them, the archwire 4 needs to have sufficient rigidity and hardness to provide sufficient force to ensure the orthodontic effect. Its material can be metal materials (such as nickel-titanium alloy, stainless steel, etc.) or non-metallic elastic materials (such as glass fiber wire, etc.). The specific selection should be based on clinical needs, and this embodiment does not make further limitations.

[0030] Among them, such as Figure 6 As shown, when the base plate 22 is directly installed on the buccal tooth surface 300 of the patient's posterior teeth, a clearance groove or clearance hole can be provided at the corresponding position of the bracketless orthodontic appliance 1 to facilitate the installation of the bracketless orthodontic appliance 1, the buccal tube 2, and the archwire 4. The first fastener 3 can be a traction buckle or a component with a fastening structure such as a protrusion, bifurcation, or groove that is inclined away from the direction of the patient's maxilla. In addition, when the buccal tube 2 is set on the bracketless orthodontic appliance 1, it should be made of transparent material; when the buccal tube 2 is directly installed on the patient's tooth surface 300, it can be made of metal or transparent material.

[0031] Example 2

[0032] like Figure 1 , Figure 2 As shown in Embodiment 1, one end of the fixing tube 21 is hinged to the base plate 22, and the other end is provided with a first fixing structure 211. On the base plate 22, corresponding to the first fixing structure 211, a plurality of second fixing structures 221 are provided. These second fixing structures 221 are arranged at intervals along the rotational trajectory of the first fixing structure 211, and are used to cooperate with the first fixing structure 211. The cooperation between the first fixing structure 211 and the second fixing structure 221 allows the fixing tube 21 to be relatively fixed to the base plate 22, thereby stabilizing the force exerted by the archwire 4 on the anterior teeth. The cooperation between the first fixing structure 211 and one of the preset second fixing structures 221 facilitates the rapid configuration of the tilt angle of the fixing tube 21 relative to the occlusal plane 100.

[0033] The first fixing structure 211 can be a protrusion or a pin, and the second fixing structure 221 can be a recess or a shaft hole that mates with the protrusion or pin, or the second fixing structure 221 can be a protrusion or a pin and the first fixing structure 211 can be a recess or a shaft hole.

[0034] As an optional technical solution, the number of second fixing structures 221 is three, and the line connecting each second fixing structure 221 to the hinge point between the fixing tube 21 and the base plate 22 forms an angle of 15°, 30° and 45° with the occlusal plane 100, respectively.

[0035] like Figure 3As shown, as an optional technical solution, the second fixing member 5 includes a connecting part 51, a first fixing part 52, and a second fixing part 53 connected in sequence; the connecting part 51 is connected to the archwire 4, the first fixing part 52 and the second fixing part 53 are annular, and the first fixing part 52 and the second fixing part 53 are internally connected, the diameter of the connection is smaller than the inner diameter of the second fixing part 53, the inner diameter of the first fixing part 52 is larger than the inner diameter of the second fixing part 53, and the second fixing part 53 is used to cooperate with the first fixing member 3. In this utility model, after the high-efficiency anterior tooth intrusion and torque-controlled combined orthodontic appliance is installed on the patient's maxillary teeth, the archwire 4 needs to be pulled towards the first fixing member 3 and fixed relative to the first fixing member 3. Due to the small operating space, the operation is difficult. Therefore, the first fixing part 52 with a larger inner diameter can be first fitted onto the outer periphery of the first fixing member 3 (e.g., Figure 3 As shown by the dashed line, under the action of the elasticity of the archwire 4 itself, the first fixing part 52 and the second fixing part 53 slide relative to the first fixing member 3 in the direction of the archwire 4 towards the patient's gingiva 200 (i.e., the direction shown by the arrow in the figure). The first fixing member 3 passes through the connection between the first fixing part 52 and the second fixing part 53 and finally cooperates with the second fixing part 53, thereby reducing the difficulty of fixing the archwire 4 and the first fixing member 3 relative to each other.

[0036] Preferably, the diameter of the first fixing part 52 along the direction from the first fixing member 3 to the archwire 4 is 1 ± 0.5 mm larger than that of the second fixing part 53, and the diameter of the first fixing part 52 along the direction from the anterior tooth region 11 to the posterior tooth region 12 is 3 ± 0.5 mm larger than that of the second fixing part 53.

[0037] As an optional technical solution, the second fixing member 5 includes a traction hook 54 and an elastic member 55. The traction hook 54 is connected to the bow wire 4, and one end of the elastic member 55 is connected to the traction hook 54, and the other end is connected to the first fixing member 3. The elastic member 55 can be a rubber ring, a spring, or an elastic wire, etc., and this embodiment does not impose any limitations.

[0038] As an optional technical solution, the buccal tube 2 is set on the buccal side of the first molar of the bracketless orthodontic appliance 1; the first fixing member 3 is set in the middle of the crown of the lateral incisor of the bracketless orthodontic appliance 1.

[0039] As an optional technical solution, the first fixing member 3 is bonded, welded, or integrally molded onto the bracketless orthodontic appliance 1 with the buccal tube 2.

[0040] As an optional technical solution, the axial length of the buccal tube 2 is 7-12 mm. Since the force exerted by the archwire 4 on the anterior teeth relies on the fixation of the end of the archwire 4 by the buccal tube 2, using a longer buccal tube 2 helps to prevent the archwire 4 from coming out of the buccal tube 2.

[0041] As an optional technical solution, the bracketless brace 1, the first fixation member 3, and the buccal tube 2 are made of transparent plastic.

[0042] Example 3

[0043] Based on Embodiment 1, the second fixing member 5 includes a traction hook 54 and an elastic member 55. The traction hook 54 is connected to the bow wire 4, and one end of the elastic member 55 is connected to the traction hook 54, while the other end is connected to the first fixing member 3. The elastic member 55 can be a rubber ring, a spring, or an elastic wire, etc., and this embodiment does not impose any limitations on it.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
