[0038] The present application 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 application, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0039] Referring to Figures 1 to 3, this is a schematic diagram of the guide plate assembly 100 according to an embodiment of this application.

[0040] The guide plate assembly 100 is used for use with the upper and lower jaw teeth. The guide plate assembly 100 includes a first guide plate 10 disposed on and protruding from the first occlusal surface A1 corresponding to the first jaw T1. The first guide plate 10 has a first functional surface 11 facing away from the first occlusal surface A1.

[0041] "A first guide plate 10 is provided on the first occlusal surface A1 corresponding to the first jaw T1 and protrudes from the first occlusal surface A1" means that the first guide plate 10 is assembled on the side of the first occlusal surface A1 close to the second jaw T2, and the first guide plate 10 protrudes from the first occlusal surface A1.

[0042] In one example, the vertical projection of the bottom surface of the first guide plate 10 near the first occlusal surface A1 onto the first occlusal surface A1 is within the outer contour of the first occlusal surface A1. That is, the outer contour of the bottom surface of the first guide plate 10 near the first occlusal surface A1 does not protrude beyond the outer contour of the first occlusal surface A1, and the first guide plate 10 is mainly set for the posterior tooth region.

[0043] When the first jaw T1 and the second jaw T2 are in occlusion, the first functional surface 11 acts on the second jaw T2 to generate at least a horizontal corrective force. The horizontal corrective force can, for example, achieve jaw position adjustment, but is not limited to this.

[0044] For example, horizontal corrective forces can adjust different types of malocclusion while simultaneously aiding in orthodontic treatment and skeletal development, specifically including the following effects:

[0045] (1) Assist in lateral jaw position adjustment: Use the guide plate assembly 100 to open the bite, so that the functional jaw position deviation is removed from the abnormal bite guidance, and cooperate with tooth movement to relieve bite interference and assist in correcting the functional jaw position deviation.

[0046] (2) Assisting lateral tooth movement: The guide plate assembly 100 is used to open the bite, so that the reverse bite, locked bite, etc. are released from the lock. At the same time, the guide plate assembly 100 is used to transmit the biting force, enhance the lateral movement support of multiple teeth, enhance the tooth movement effect, assist in enhancing the arch expansion effect, etc.

[0047] (3) Assisted growth guidance of transverse bone growth during the growth period: Using the guide plate assembly 100 to open the bite and guide the transverse position of the jawbone, assisting the jawbone with growth potential to guide transverse growth.

[0048] The first functional surface 11 of the first guide plate 100 can directly interact with the second jaw T2 to generate a horizontal orthodontic force. That is, at this time, no guide plate is set at the second jaw T2, and the guide plate assembly 100 is only set for a single jaw.

[0049] Alternatively, the guide plate assembly 100 may further include a second guide plate 20 disposed on the second occlusal surface A2 corresponding to the second occlusal surface A2 of the second jaw T2. The second guide plate 20 has a second functional surface 21 facing away from the second occlusal surface A2. When the first jaw T1 and the second jaw T2 are in an occlusal state, the first functional surface 11 and the second functional surface 21 interact to generate at least a horizontal corrective force.

[0050] Here, the explanation will focus on an example where the guide assembly 100 includes both a first guide plate 10 and a second guide plate 20. The guide assembly 100 can be directly added to the teeth, or the guide assembly 100 can be first added to a shell-shaped dental instrument, and then worn together with the shell-shaped dental instrument onto the teeth. The shell-shaped dental instrument is an invisible brace.

[0051] In the first example, referring to Figure 1, both the first guide plate 10 and the second guide plate 20 are directly added to the teeth. The first guide plate 10 is added to the first occlusal surface A1 of the first jaw T1, and the second guide plate 20 is added to the second occlusal surface A2 of the second jaw T2.

[0052] In a second example, a shell-shaped dental instrument assembly 400 is also proposed. The shell-shaped dental instrument assembly 400 includes a first shell-shaped dental instrument 200 and a guide plate assembly 100. The first shell-shaped dental instrument 200 is positioned corresponding to a first jaw T1, and a first guide plate 100 is fixed to the area of ​​the first shell-shaped dental instrument 200 corresponding to the first occlusal surface A1. A second guide plate 20 is directly added to the second occlusal surface A2 of the second jaw T2. The first guide plate 10 is integrally formed with the first shell-shaped dental instrument 200, but this is not a limitation.

[0053] In the third example, referring to Figures 2 and 3, a shell-shaped dental instrument assembly 400 is also proposed. The shell-shaped dental instrument assembly 400 includes a first shell-shaped dental instrument 200, a second shell-shaped dental instrument 300, and a guide plate assembly 100. The first shell-shaped dental instrument 200 is positioned corresponding to a first occlusal surface T1. The second shell-shaped dental instrument 300 is positioned corresponding to a second occlusal surface T2. The first guide plate 10 is fixed to the region of the first shell-shaped dental instrument 200 corresponding to the first occlusal surface A1. The second guide plate 20 is fixed to the region of the second shell-shaped dental instrument 300 corresponding to the second occlusal surface A2. The first guide plate 10 is integrally formed with the first shell-shaped dental instrument 200, and the second guide plate 20 is integrally formed with the second shell-shaped dental instrument 300, but this is not a limitation.

[0054] The first shell-shaped dental instrument 200 has a first cavity S1 for accommodating teeth, and the first guide plate 10 has a receiving cavity S communicating with the first cavity S1.

[0055] The first shell-shaped dental instrument 200 may also include a filler located in the receiving cavity S, which can enhance the strength of the first guide plate 10 and reduce the risk of damage or collapse. A description of the second shell-shaped dental instrument 300 can be found in the first shell-shaped dental instrument 200.

[0056] As can be seen, the first guide plate 10 can be added to the teeth or the first shell-shaped dental instrument 200, and the second guide plate 20 can be added to the teeth or the second shell-shaped dental instrument 300. The specific addition method can be determined according to actual needs.

[0057] In this embodiment, the first functional surface 11 and the second functional surface 21 are planes, inclined planes or curved surfaces, or the first functional surface 11 and the second functional surface 21 are formed by splicing together at least two of planes, inclined planes or curved surfaces.

[0058] At least one of the first functional surface 11 and the second functional surface 21 includes a friction region. The friction region includes a sawtooth structure, a wavy structure, a raised structure, or a recessed structure. Thus, when the first functional surface 11 and the second functional surface 21 interact, the mating stability and the transmission of force can be improved.

[0059] In this embodiment, referring to FIG4, the first functional surface 11 or the second functional surface 21 includes an inclined surface. Here, the first functional surface 11 includes a first inclined surface 111 as an example.

[0060] When the first guide plate 10 is assembled to the tooth, an acute angle α is formed between the first inclined surface 111 and the jaw plane P, and the acute angle α ranges from 30° to 60°.

[0061] Alternatively, referring to Figure 5, the first functional surface 11 or the second functional surface 21 includes a curved surface, with the first functional surface 111 including the first curved surface 112 as an example.

[0062] When the first guide plate 10 is assembled to the tooth, an acute angle β is formed between the tangent of the first curved surface 112 and the jaw plane P, and the acute angle β ranges from 30° to 60°.

[0063] Here, the sectional plane refers to the sectional plane on the first curved surface 112 that is in contact with the main mating area of ​​the second guide plate 20 of the jaw, and the jaw plane P is roughly horizontal.

[0064] Furthermore, the jaws are guided along the first inclined plane 111 or the first curved surface 112, which can generate at least a horizontal corrective force. Here, due to the presence of an acute angle, there is actually a combined corrective force in both the horizontal and vertical directions.

[0065] It should be noted that the acute angle α (or β) points towards the tongue or cheek. Alternatively, the acute angle may point away from the tongue or cheek.

[0066] In other words, referring to Figure 6, the first inclined plane 111 or the first curved surface 112 can rotate clockwise or counterclockwise around the longitudinal axis perpendicular to the jaw plane P, so that the orientation of the acute angle α (or β) can be adjusted, thereby providing horizontal but different orthodontic forces, such as adjusting different angles of jaw deviation.

[0067] Here, the angle by which the first inclined plane 111 or the first curved surface 112 rotates clockwise or counterclockwise is, for example, no greater than 30° or no greater than 45°.

[0068] Alternatively, the first functional surface 11 or the second functional surface 21 includes a plane that is parallel to the jaw plane P when the first guide plate 10 and the second guide plate 20 are assembled to the tooth.

[0069] In this embodiment, referring to FIG7, the first functional surface 11 includes a first inclined surface 111 and a first flat surface 113, and the second functional surface 21 includes a second inclined surface 211 and a second flat surface 213. When the first guide plate 10 and the second guide plate 20 are assembled to the teeth and come into contact with each other, the first inclined surface 111 and the second inclined surface 211 are in contact with each other, and the first flat surface 113 and the second flat surface 213 are in contact with each other.

[0070] Here, the inclined plane mainly achieves horizontal jaw position adjustment, while the plane mainly achieves vertical jaw position adjustment. By combining the inclined plane and the plane, a combined jaw position adjustment can be achieved.

[0071] In this embodiment, referring to Figures 8 to 10, the first functional surface 11 and the second functional surface 21 are complementary in shape. For example, referring to Figure 8, both the first functional surface 11 and the second functional surface 21 include an inclined plane and a plane. Referring to Figure 9, both the first functional surface 11 and the second functional surface 21 are inclined planes. Referring to Figure 10, both the first functional surface 11 and the second functional surface 21 are curved surfaces.

[0072] Referring to Figure 11, in order to improve the stability of the fit between the first guide plate 10 and the second guide plate 20, a limiting part 30 can be formed at the first guide plate 10 and the second guide plate 20. Here, taking the end of the first functional surface 11 of the first guide plate 10 having a limiting part 30 as an example, the limiting part 30 is a hook structure, which can prevent the second guide plate 20 from disengaging from the first guide plate 10 in the direction of the limiting part 30.

[0073] In this embodiment, the first guide plate 10 and the second guide plate 20 are the same or similar guide plates, which simplifies the manufacturing process, improves versatility, and allows different functions to be achieved through different placement methods.

[0074] Of course, the first guide plate 10 and the second guide plate 20 can also be structures with different shapes or different sizes.

[0075] In this embodiment, referring to FIG12, the first guide plate 10 further includes a first non-functional surface 114 and a first additive surface 115. The first additive surface 115 mates with the teeth, and the first non-functional surface 114 connects the first additive surface 115 and the first functional surface 111.

[0076] When the first guide plate 10 is added to the tooth, the first adding surface 115 is fully embedded in the tooth, thereby increasing the contact area between the first guide plate 10 and the tooth. In practice, the first adding surface 115 of the digitized first guide plate 10 can be fully embedded in the digitized dental model during the design phase.

[0077] The first functional surface 11 can also be partially embedded in the tooth, depending on the actual situation.

[0078] The first non-functional surface 114 is formed by splicing together planar and / or curved surfaces. The first non-functional surface 114 has a reinforcing structure, which is a raised structure or a recessed structure, and the reinforcing structure can enhance the strength and stability of the first non-functional surface 114.

[0079] In this embodiment, the first adding surface 115 is disposed opposite to the first functional surface 111, and the first adding surface 115 and the first functional surface 111 are disconnected from each other, or the first adding surface 115 is connected to the first functional surface 111.

[0080] The first added surface 115 corresponds to the first occlusal surface A1.

[0081] In this embodiment, the first guide plate 10 is configured for a single tooth, or the first guide plate 10 is configured for multiple consecutive teeth, or multiple first guide plates 10 are configured for multiple teeth.

[0082] Here, when the first guide plate 10 is added to a single tooth for jaw adjustment, the jaw adjustment force will be concentrated on that tooth, allowing for assisted tooth movements. When the first guide plate 10 is added to multiple teeth (multiple first guide plates 10 corresponding to multiple teeth, or one first guide plate 10 corresponding to multiple consecutive teeth), the jaw adjustment force will be dispersed.

[0083] For details regarding the second guide plate 20, please refer to the first guide plate 10; further details will not be provided here.

[0084] It should be noted that by adjusting the relative position, angle, and other parameters of the first guide plate 10 and the second guide plate 20 of the guide plate assembly 100, jaw position adjustment in a single direction, primarily in the horizontal direction, can be achieved. By adjusting the relative position, angle, and other parameters of multiple sets of guide plate assemblies 100, complex jaw position adjustments in the horizontal direction can be achieved.

[0085] Referring to Figures 13 to 16, one embodiment of this application also provides a guide plate system, including multiple sets of guide plate assemblies 100.

[0086] Multiple guide plate assemblies 100 are set to correspond to the posterior tooth regions on both sides, that is, multiple guide plate assemblies 100 are set to correspond to the left posterior tooth region and the right posterior tooth region, which can improve stability.

[0087] Of course, in other embodiments, the guide plate assembly 100 may be provided only in the posterior tooth region on one side.

[0088] In this embodiment, when guide plate assemblies 100 are simultaneously provided in both the left and right posterior tooth regions, the guide plate assemblies 100 can achieve different types of jaw position adjustments by adjusting parameters such as relative position and angle. For example, they can achieve simple jaw position adjustments, assisted arch expansion, or arch reduction.

[0089] One or more guide plate assemblies 100 can be installed in the left posterior tooth region, and one or more guide plate assemblies 100 can be installed in the right posterior tooth region. This not only enables jaw position adjustment but also provides targeted tooth movement assistance. Furthermore, by combining this with different orientations of the acute angles mentioned earlier, various complex adjustments can be achieved.

[0090] Specifically, taking the multi-group guide plate assembly 100, including a first group guide plate assembly 100a and a second group guide plate assembly 100b, as an example. The first guide plate 10a of the first group guide plate assembly 100a is positioned for the mandibular teeth in the left posterior tooth region, and the first functional surface 11a of the first guide plate 10a includes a first inclined surface 111a, which forms a first acute angle α1 with the occlusal plane. The first guide plate 10b of the second group guide plate assembly 100b is positioned for the mandibular teeth in the right posterior tooth region, and the first functional surface 11b of the first guide plate 10b includes a first inclined surface 111b, which forms a second acute angle α2 with the occlusal plane P. The first acute angle α1 and the second acute angle α2 have the same orientation, or the first acute angle α1 and the second acute angle α2 have opposite orientations.

[0091] Referring to Figure 13, the first acute angle α1 points towards the buccal surface of the left posterior tooth region, and the second acute angle α2 points towards the buccal surface of the right posterior tooth region. At this time, the mandibular teeth in the left posterior tooth region move outward, and the mandibular teeth in the right posterior tooth region move outward, which can assist in arch expansion.

[0092] Referring to Figure 14, the first acute angle α1 points towards the lingual surface of the left posterior tooth region, and the second acute angle α2 points towards the lingual surface of the right posterior tooth region. At this time, the mandibular teeth in the left posterior tooth region move inward, and the mandibular teeth in the right posterior tooth region move inward, which can assist in arch reduction.

[0093] Referring to Figure 15, the first acute angle α1 points towards the buccal surface of the left posterior tooth region, and the second acute angle α2 points towards the lingual surface of the right posterior tooth region. At this time, the mandibular teeth in the left posterior tooth region move outward, and the mandibular teeth in the right posterior tooth region move inward, which can cause the mandible to shift to the left as a whole, achieving a leftward jaw position adjustment.

[0094] Referring to Figure 16, the first acute angle α1 points towards the lingual surface of the left posterior tooth region, and the second acute angle α2 points towards the buccal surface of the right posterior tooth region. At this time, the mandibular teeth in the left posterior tooth region move inward, and the mandibular teeth in the right posterior tooth region move outward, which can cause the mandible to shift to the right as a whole, thus achieving a rightward jaw position adjustment.

[0095] In addition, the orientation of the first acute angle α1 and the orientation of the second acute angle α2 form an acute or obtuse angle. That is to say, the orientation of the first inclined planes 111a and 111b can be adjusted according to the actual situation. They do not necessarily have to be the same or opposite, and can also be set at a certain angle to accommodate more orthodontic needs.

[0096] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.

[0097] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
