[0030] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0031] Combination Figure 1 This is a schematic diagram of the orthodontic component 100 according to an embodiment of the present utility model.

[0032] The orthodontic component 100 includes a first protrusion structure 10 disposed on the labial or buccal side or lingual side corresponding to the first occlusal T1. The first protrusion structure 10 is configured such that when the first protrusion structure 10 abuts against the opposing second occlusal T2, a first occlusal position H1 is formed. The first occlusal position H1 deviates from the initial occlusal position H, and the first occlusal force corresponding to the first occlusal position H1 is greater than the initial occlusal force corresponding to the initial occlusal position H.

[0033] One of the first jaw T1 and the second jaw T2 is the maxilla, and the other is the mandible. For ease of explanation, we will take the example of the first jaw T1 being the maxilla and the second jaw T2 being the mandible.

[0034] "The first protruding structure 10 abuts against the opposing second tooth T2" can mean that the first protruding structure 10 directly abuts against the second tooth T2, or it can mean that the first protruding structure 10 indirectly abuts against the second tooth T2 through other structures.

[0035] Optionally, the first jaw position H1 can be raised by the mutual abutment of the first protruding structure 10 and the second jaw T2 (e.g., Figure 1 The first jaw T1 shown is raised by h), so that the first jaw position H1 formed between the first jaw T1 and the second jaw T2 deviates from the initial jaw position H before the elevation. The relatively higher first jaw position H1 corresponds to a relatively larger first occlusal force.

[0036] This embodiment achieves the first jaw position H1 by the mutual contact of the first protruding structure 10 and the second jaw T2. The first jaw position H1 has a larger first occlusal force, which can provide a greater orthodontic force for the first jaw T1 and the second jaw T2.

[0037] In addition, the first jaw position H1 can be controlled by controlling the relative position of the first protruding structure 10 and the second jaw T2, thereby effectively controlling the orthodontic force.

[0038] Optionally, the initial jaw position H can be a custom jaw position or a specific jaw position; for example, the initial jaw position H can be a resting jaw position.

[0039] The resting jaw position can be defined as the position that the first jaw T1 and the second jaw T2 automatically find when they are in a normal relaxed state. For example, when the mouth is not chewing, swallowing, or speaking, the second jaw T2 is in a resting state, and the dental arches of the first jaw T1 and the second jaw T2 are naturally separated. The jaw position formed by the first jaw T1 and the second jaw T2 at this time is called the resting jaw position.

[0040] The resting jaw position corresponds to an initial occlusal force of zero. Alternatively, the resting jaw position can also be a jaw position with a small occlusal force between the first jaw T1 and the second jaw T2. For example, the jaw position where the initial occlusal force is less than the initial value is called the resting jaw position.

[0041] Optionally, the degree of opening of the first jaw position H1 is positively correlated with the first occlusal force, and the degree of opening includes the opening angle or gap between the first jaw T1 and the second jaw T2.

[0042] When the first jaw T1 and the second jaw T2 open, the jaw muscles are released and generate force. This force is applied to the first protruding structure 10 and the second jaw T2 that are abutting each other and is converted into the first biting force.

[0043] When the opening angle or gap between the first jaw (T1) and the second jaw (T2) is large, the greater the degree of release of the jaw muscles, the greater the first biting force.

[0044] Optionally, the opening angle between the first jaw T1 and the second jaw T2 can refer to the rotation angle of the second jaw T2 relative to the first jaw T1 relative to the closed state.

[0045] When the first jaw T1 and the second jaw T2 are in the first jaw position H1, a first opening angle is formed between the first jaw T1 and the second jaw T2. When the first jaw T1 and the second jaw T2 are in the initial jaw position H, an initial opening angle is formed between the first jaw T1 and the second jaw T2. The first opening angle is greater than the initial opening angle, which corresponds to the first occlusal force being greater than the initial occlusal force.

[0046] Optionally, the gap between the first jaw T1 and the second jaw T2 refers to the downward movement distance of the second jaw T2 during the rotation of the second jaw T2 relative to the first jaw T1 in the closed state.

[0047] When the first jaw T1 and the second jaw T2 are in the first jaw position H1, a first gap is formed between the first jaw T1 and the second jaw T2. When the first jaw T1 and the second jaw T2 are in the initial jaw position, an initial gap is formed between the first jaw T1 and the second jaw T2. The first gap is larger than the initial gap, which corresponds to the first occlusal force being greater than the initial occlusal force.

[0048] This embodiment can control the first occlusal force by controlling the first opening angle and / or the first gap between the first jaw T1 and the second jaw T2, so as to meet the orthodontic requirements.

[0049] Optionally, the orthodontic component 100 includes a plurality of first protrusion structures 10 corresponding to multiple teeth.

[0050] Combination Figure 2 At least some of the first protrusion structures 10 are arranged at intervals, each first protrusion structure 10 corresponds to a tooth or the gap between two adjacent teeth, and each first protrusion structure 10 can be designed independently to meet the orthodontic needs of each tooth.

[0051] Or, combine Figure 3 At least a portion of the first protrusion structure 10 is connected as a whole, and the connected at least a portion of the first protrusion structure 10 extends to cover at least one tooth and at least one gap between teeth. The connected at least a portion of the first protrusion structure 10 has a large volume, which can improve stability and strength.

[0052] Optional, combined Figures 4 to 6 The first protrusion structure 10 is directly connected to the tooth of the first jaw T1, or the orthodontic assembly 100 further includes a first orthodontic appliance 101 having a first cavity S1 for accommodating the first jaw T1, wherein the first protrusion structure 10 is located on the labial / buccal surface A1 or the lingual surface A2 of the first orthodontic appliance 101.

[0053] The first protruding structure 10 can directly or indirectly abut against the second jaw T2.

[0054] When the first protruding structure 10 directly abuts against the second jaw T2, the first protruding structure 10 can directly abut against the tooth area of ​​the second jaw T2.

[0055] When the first protrusion structure 10 indirectly abuts against the second jaw T2, the orthodontic component 100 may include a second protrusion structure 20 directly connected to the second jaw T2, and the first protrusion structure 10 abuts against the second protrusion structure 20 to achieve indirect abutment with the second jaw T2.

[0056] Optionally, the first protrusion 10 can directly abut against the anterior incisal end Q or the occlusal surface of the posterior tooth of the second occlusal tooth T2.

[0057] Alternatively, the orthodontic assembly 100 may also include a second orthodontic appliance 102 having a second cavity S2 for accommodating the second jaw T2, wherein a first protrusion 10 abuts against the area of ​​the second orthodontic appliance 102 that is in close contact with the second jaw T2 to achieve indirect contact with the second jaw T2.

[0058] Optionally, the first protruding structure 10 and the area of ​​the second orthodontic appliance 102 that is in close contact with the incisal edge Q of the anterior teeth or the occlusal surface of the posterior teeth are mutually abutted.

[0059] Alternatively, the orthodontic component 100 may include a second protrusion structure 20 located on the second orthodontic appliance 102, wherein the first protrusion structure 10 abuts against the second protrusion structure 20 to achieve indirect contact with the second occlusal T2.

[0060] When the orthodontic assembly 100 includes a first orthodontic appliance 101 and a second orthodontic appliance 102, the first orthodontic appliance 101 and the second orthodontic appliance 102 may be invisible braces made of polymer materials.

[0061] When the orthodontic component 100 includes a second protrusion structure 20, the second protrusion structure 20 can be provided on the labial or buccal side, lingual side, incisal edge of the anterior tooth, or occlusal surface of the posterior tooth of the second occlusal tooth T2, and the first protrusion structure 10 and the second protrusion structure 20 abut against each other to form a first occlusal position H.

[0062] The following describes several ways in which the first protruding structure 10 and the second jaw T2 can be matched.

[0063] In the first form of coordination, combination Figure 4 The orthodontic component 100 includes a first orthodontic appliance 101, a second orthodontic appliance 102, a first protruding structure 10 and a second protruding structure 20, wherein the first protruding structure 10 indirectly abuts against the second occlusal tooth T2.

[0064] The first protruding structure 10 is located on the lingual surface A2 of the first orthodontic appliance 101, and the second protruding structure 20 is located on the labial surface A1 of the second orthodontic appliance 102. The first protruding structure 10 and the second protruding structure 20 abut against each other to form the first jaw position H1.

[0065] In the second form of coordination, combination Figure 5 The orthodontic component 100 includes a first orthodontic appliance 101, a second orthodontic appliance 102, and a first protrusion structure 10, the first protrusion structure 10 indirectly abutting against the second jaw T2.

[0066] The first protruding structure 10 is located on the lingual surface A2 of the first orthodontic appliance 101. The first protruding structure 10 abuts against the area of ​​the anterior incisal edge Q2 of the second orthodontic appliance 102 that is close to the second occlusal T2. The first protruding structure 10 and the second orthodontic appliance 102 abut against each other to form the first occlusal position H1.

[0067] In the third form of coordination, combination Figure 6 The orthodontic component 100 includes a first orthodontic appliance 101 and a first protruding structure 10, the first protruding structure 10 directly abutting against the second jaw T2.

[0068] The first protruding structure 10 is located on the lingual surface A2 of the first orthodontic appliance 101. The first protruding structure 10 abuts against the incisal end Q2 of the second jaw T2. The first protruding structure 10 and the second jaw T2 abut against each other to form the first jaw position H1.

[0069] Below, in conjunction with Figure 7 Taking the deep overbite treatment scenario as an example, the orthodontic component 100 will be further explained. The orthodontic component 100 includes a first orthodontic appliance 101, a second orthodontic appliance 102, a first protruding structure 10 and a second protruding structure 20.

[0070] The first protruding structure 10 is provided on the labial / buccal side of the first jaw T1 and the second protruding structure 20 is provided on the lingual side of the second jaw T2, or the first protruding structure 10 is provided on the lingual side of the first jaw T1 and the second protruding structure 20 is provided on the labial / buccal side of the second jaw T2.

[0071] In deep overbite treatment, the first jaw T1 covers at least part of the second jaw T2. It is necessary to indent the first jaw T1 and the second jaw T2 to improve the deep overbite. However, the first jaw T1 and the second jaw T2 are usually relatively vertical in their initial state. The initial relative positions of the first jaw T1, the second jaw T2 and the alveolar bone are not suitable for direct absolute indentation of the first jaw T1 and the second jaw T2. Therefore, it is necessary to adjust the relative positions of the first jaw T1 and the alveolar bone and the second jaw T2 and the alveolar bone first.

[0072] The first protrusion structure 10 is provided on the lingual side of the maxillary (first tooth T1) anterior teeth, and the second protrusion structure 20 is provided on the labial side of the mandibular (second tooth T2) anterior teeth. When the first protrusion structure 10 and the second protrusion structure 20 abut against each other, a torque is generated. The torque includes only the maxillary labial inclination torque M1 or the torque includes both the maxillary labial inclination torque M1 and the mandibular labial inclination torque M2.

[0073] When the torque only includes the maxillary labial inclination torque M1, the torque only achieves the labial inclination of the first tooth T1.

[0074] When the torque includes maxillary labial inclination torque M1 and mandibular labial inclination torque M2, the torque simultaneously achieves labial inclination of the first jaw T1 and the second jaw T2.

[0075] When the torque only includes the maxillary labial inclination torque M1, the relative position of the first jaw T1 and the alveolar bone can be adjusted to make the first jaw T1 suitable for intrusion operation; the gap between the first jaw T1 and the second jaw T2 can be increased to facilitate the setting of the first protrusion structure 10 and the second protrusion structure 20; the first jaw T1 has a certain inclination to facilitate interaction with the second jaw T2, which facilitates the intrusion and retraction of the upper and lower anterior teeth.

[0076] When the torque includes maxillary labial inclination torque M1 and mandibular labial inclination torque M2, the relative position of the second jaw T2 and the alveolar bone can be adjusted to make the second jaw T2 suitable for intrusion operations; it can avoid the aggravation of deep overbite caused by the lingual inclination of the second jaw T2; the second jaw T2 has a certain degree of inclination, which can facilitate interaction with the first jaw T1, and facilitate the intrusion and retraction of the upper and lower anterior teeth.

[0077] Optional, combined Figure 8 In the case of deep overbite correction, the entire correction process usually needs to be divided into multiple correction steps. The absolute value of the lever arm corresponding to the maxillary labial tilt torque M1 in the Nth correction step is not less than the absolute value of the lever arm corresponding to the maxillary labial tilt torque M1' in the N+Mth correction step, where N and M are both positive integers.

[0078] This corresponds to the degree of labial inclination of the first tooth T1 in the Nth orthodontic step being no less than the degree of labial inclination of the first tooth T1 in the N+M orthodontic step.

[0079] The absolute value of the lever arm corresponding to the mandibular tilting moment M2 in the Nth correction step is not greater than the absolute value of the lever arm corresponding to the mandibular tilting moment M2' in the N+Mth correction step, where N and M are both positive integers.

[0080] This corresponds to the degree of labial inclination produced by the second jaw T2 in the Nth orthodontic step not being greater than the degree of labial inclination produced by the second jaw T2 in the N+M orthodontic step.

[0081] When deep overbite treatment is in the relatively early Nth orthodontic step, since the first jaw T1 and the second jaw T2 are usually relatively vertical, a relatively large labial tipping moment can be provided to the first jaw T1 to adjust the relative position of the first jaw T1 and the alveolar bone to a larger extent first. The relative position of the second jaw T2 and the alveolar bone can be left unadjusted at first, or a relatively small labial tipping moment can be provided to adjust the relative position of the second jaw T2 and the alveolar bone to a smaller extent.

[0082] Optionally, while the first occlusal T1 exhibits labial inclination, the first occlusal T1 may also exhibit a certain degree of indentation.

[0083] Then, when the deep overbite treatment is in the relatively late N+M treatment step, the labial inclination of the first tooth T1 has progressed to a certain extent. At this time, the labial inclination torque of the first tooth T1 can be reduced to avoid excessive labial inclination of the first tooth T1. At the same time, the labial inclination torque of the second tooth T2 can be increased, thereby adjusting the relative position of the second tooth T2 and the alveolar bone to a greater extent.

[0084] Optionally, while the second occlusal T2 exhibits labial inclination, it may also exhibit a certain degree of intrusion.

[0085] Subsequently, when the labial inclination of the first jaw T1 and the labial inclination of the second jaw T2 have reached a certain level, the deep overbite condition has also been improved to a certain extent, and there is a certain space between the first jaw T1 and the second jaw T2 to achieve absolute intrusion.

[0086] Absolute compression mainly refers to the force generated by the mutual contact between the first protrusion structure 10 and the second protrusion structure 20, which mainly achieves compression. For example, the first protrusion structure 10 can be set close to or directly set at the anterior incisal end Q1 of the first jaw T1, and the second protrusion structure 20 can be set close to or directly set at the anterior incisal end Q2 of the second jaw T2, so that a larger proportion of the force can be used to achieve compression of the first jaw T1 and the second jaw T2.

[0087] Optional, combined Figure 9 The first protruding structure 10 abuts against the opposing second tooth T2 to form a contact area D. Here, the contact area D formed by the first protruding structure 10 and the second protruding structure 20 abutting against each other is used as an example for explanation.

[0088] At least some of the different orthodontic steps of the orthodontic components 100 have different contact areas D, and different contact areas D correspond to different translation and / or rotation amounts.

[0089] Translation and / or rotation amounts, for example, generate torque as described above. Different contact areas D can be selected depending on the required translation and / or rotation amounts.

[0090] Optionally, different contact areas D have different parameters, including at least one of the following: the setting position of contact area D, the shape of contact area D, the position of contact point O formed by contact area D, and the direction of the line of action L passing through contact point O.

[0091] The location of the contact area D is defined as the spatial position of the contact area D within the accommodating space S, which is the gap formed between the first jaw T1 and the second jaw T2 to accommodate the first protruding structure 10.

[0092] Optionally, the contact area D can be positioned, for example, near the anterior incisal edge Q1 of the first jaw T1, near the anterior incisal edge Q2 of the second jaw T2, or in the area between the anterior incisal edge Q1 of the first jaw T1 and the anterior incisal edge Q2 of the second jaw T2.

[0093] The morphology of the contact area D includes at least one of the following: the geometry of the contact area D, and the direction of extension of the contact area D.

[0094] Optionally, the contact area D can be a plane or a curved surface. When the contact area D is a plane, the geometry of the contact area D can be a regular shape such as a circle, ellipse, square, triangle or other irregular shape. When the contact area D is a curved surface, the geometry of the contact area D can be defined by the curvature of the contact area D.

[0095] The extension direction of the contact area D is, for example, the horizontal direction, or the direction that forms different angles with the horizontal direction.

[0096] The location of the contact point O formed by the contact area D is defined as the spatial location of the geometric center or force center O of the contact area D within the accommodating space S.

[0097] When the contact area D is a plane, the geometric center O is defined as the center or centroid of the plane, and the force center O is defined as the resultant point of all forces acting on the plane. The force center O can overlap with the geometric center O.

[0098] When the contact area D is a curved surface, the force center O is defined as the resultant point of all forces acting on the curved surface.

[0099] In summary, this utility model can achieve a first jaw position H1 by the mutual contact of the first protruding structure 10 and the second jaw T2. The first jaw position H1 has a larger first occlusal force, which can provide greater orthodontic force for the first jaw T1 and the second jaw T2.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0101] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model.
