An orthodontic appliance with adjustable occlusal pad thickness in the molar region

Abstract

This invention provides an adjustable occlusal pad thickness for the molar region, comprising a U-shaped occlusal pad. The outer edges of the occlusal pad extend upwards and downwards to form labial and buccal barriers, and the inner edges extend upwards and downwards to form lingual barriers. The occlusal pad, labial and buccal barriers, and lingual barriers together form an integrated upper and lower occlusal appliance that adapts to tooth occlusion. The occlusal pad of the occlusal appliance includes an anterior occlusal pad and a molar region occlusal pad. The thickness of the anterior occlusal pad is fixed and cannot be adjusted. The molar region occlusal pad includes a receiving groove and an adjustment pad. The adjustment pad is a removable, rectangular strip-shaped piece that can be placed in the receiving groove. The adjustment pad has various sizes and thicknesses. Since the thickness of the anterior occlusal pad is not adjustable, the thickness of the molar region occlusal pad can be adjusted by replacing the adjustment pad with different sizes and thicknesses. Therefore, by adjusting the thickness of the molar region occlusal pad, the thickness of the anterior and posterior occlusal pads can be differentiated, thereby controlling the development of different types of vertical malocclusion in children.

Description

Technical Field

[0001] This invention relates to the field of orthodontic technology, specifically to an adjustable occlusal pad thickness in the molar region. Background Technology

[0002] Existing silicone braces are mainly made of medical-grade silicone material. These braces are early correction devices that utilize growth and development to correct malocclusion. They are aesthetically pleasing and comfortable to wear, avoiding problems such as children refusing to wear braces due to pain and adverse physical and mental development. As a result, more and more people are using silicone braces as an early correction tool for malocclusion.

[0003] However, the thickness of the occlusal pad in existing orthodontic appliances is fixed. Children's treatment situations vary at different stages. Because the thickness is not adjustable, it cannot effectively control the vertical growth of different dental areas in front and behind the teeth, especially cases of deep overbite, edge-to-edge anterior teeth, and anterior open bite, and thus cannot improve the vertical developmental deformities of the anterior and posterior jawbones.

[0004] With the advancement of technology and the increasing abundance of digital products, the application of oral model data and the development of orthodontic design software have enabled the precise measurement of children's orthodontic data. This has changed the traditional practice of clinicians relying on the naked eye to judge the space of the teeth and jawbone and the development of the root bone. Therefore, there is an urgent need to design a series of digitally induced orthodontic appliances that are suitable for children's developmental stages and can more accurately meet the needs of children at different stages of tooth and jawbone development. Summary of the Invention

[0005] The problem this invention aims to solve is to overcome the deficiencies of the prior art by providing an adjustable molar occlusal pad thickness induced orthodontic appliance. By adjusting the thickness of the molar occlusal pad, the thickness of the anterior and posterior molar occlusal pads can be relatively changed according to the orthodontic needs. During the orthodontic process, the thickness of the molar occlusal pad can be adjusted according to the malocclusion problems of different children or the orthodontic needs at different stages of the child's treatment, thereby inducing the vertical development of teeth in different dental areas and solving the problems of vertical malocclusion and unstable occlusal relationships in related technologies.

[0006] The technical problem of this invention can be solved by the following technical solution:

[0007] An adjustable thickness occlusal pad for molar region is provided as an orthodontic appliance, comprising a U-shaped occlusal pad, including an anterior occlusal pad and a molar occlusal pad. The outer edges of the occlusal pad extend upward and downward to form labial and buccal barriers, respectively, and the inner edges of the occlusal pad extend upward and downward to form lingual barriers, respectively. The occlusal pad, labial and buccal barriers, and lingual barriers together form an integrated upper and lower orthodontic appliance that adapts to tooth occlusion.

[0008] In some embodiments, the orthodontic appliance includes a receiving groove located on one side inside the molar occlusal pad, and an adjustment pad housed within the receiving groove. The receiving groove and the adjustment pad are detachably connected. The receiving groove has a rectangular cavity structure, and the adjustment pad is shaped like a rectangular strip that matches the shape of the receiving groove.

[0009] When the adjusting pad is placed in the receiving groove, the thickness of the molar occlusal pad can vary to different degrees.

[0010] In some embodiments, the receiving groove includes a long end face of the receiving groove, and the adjusting pad includes a long end face of the adjusting pad disposed inside the receiving groove, the shape of the long end face of the adjusting pad matching the shape of the long end face of the receiving groove.

[0011] In some embodiments, the long end face shape of the receiving groove includes a smooth plane or a wavy plane, and the long end face shape of the adjusting pad also includes a smooth plane or a wavy plane that matches the long end face shape of the receiving groove.

[0012] In some embodiments, the end of the receiving slot includes a second transverse end face of the receiving slot located on one side of the end of the molar occlusal pad. The second transverse end face of the receiving slot is an open surface that is connected and penetrates the outside of the orthodontic appliance. The shape of the second transverse end face of the receiving slot is set as an arc surface that conforms to the shape of the dental arch in the oral cavity.

[0013] The adjusting pad includes a second transverse end face of the adjusting pad that is housed inside the receiving groove, and the shape of the second transverse end face of the adjusting pad includes an arc-shaped curved surface that matches the shape of the second transverse end face of the receiving groove.

[0014] In some embodiments, the receiving groove includes a receiving groove limiting angle protruding into the receiving groove, the receiving groove limiting angle being located at the interface between the long end face of the receiving groove and the second transverse end face of the receiving groove;

[0015] The adjusting pad includes an adjusting pad limiting angle that is housed inside the receiving groove and contacts the limiting angle of the receiving groove. The adjusting pad limiting angle is located at the interface between the long end face of the adjusting pad and the second horizontal end face of the adjusting pad and is concave. The adjusting pad limiting angle and the limiting angle of the receiving groove have a convex shape that matches each other.

[0016] In some embodiments, the receiving groove includes a first transverse end face of the receiving groove, which is a cut surface closed at both ends;

[0017] The adjusting pad includes one that contacts the first horizontal end face of the receiving groove. The first horizontal end face of the adjusting pad is a smooth plane, and the shape of the first horizontal end face of the adjusting pad matches the shape of the first horizontal end face of the receiving groove.

[0018] The straight-line distance between the two sides of the opening on the second horizontal end face of the receiving groove is not greater than the length of the cross-section of the first horizontal end face of the receiving groove.

[0019] In some embodiments, the adjusting pad includes an adjusting pad baffle located outside the receiving groove. The adjusting pad baffle is located at the outer edge of the second transverse end face of the adjusting pad. The shape of the adjusting pad baffle includes an arc-shaped curved surface that conforms to the shape of the dental arch in the oral cavity. The height of the adjusting pad baffle is greater than the thickness of the first transverse end face and the second transverse end face of the adjusting pad, and less than or equal to the thickness of the molar occlusal pad.

[0020] In some embodiments, the occlusal pad includes a flow guide hole penetrating the upper and lower surfaces of the occlusal pad, and the flow guide hole is a hole with a certain shape.

[0021] In some embodiments, the flow guide hole communicates with the receiving groove.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] This invention provides an adjustable occlusal slab thickness in the molar region, which can prevent and treat early malocclusion. Structurally, it is designed based on the actual oral structure of Chinese people, with added detailed structural components, allowing the thickness of the occlusal slab in the molar region at the rear end of the appliance to be adjusted. By utilizing the change in occlusal slab thickness, the vertical growth relationship between the anterior teeth and molars can be controlled, thereby effectively controlling the vertical development of the maxilla and mandible, meeting the vertical development needs of different types of jaws, and reducing the occurrence or recurrence of malocclusion problems in the permanent dentition stage.

[0024] This invention provides an orthodontic appliance with adjustable thickness of the molar occlusal pad. Its alveolar-free design avoids the problem of Bolton index misalignment. While aligning teeth, the wearer can adjust to a more stable occlusal relationship by changing the thickness of the molar occlusal pad.

[0025] This invention provides an orthodontic appliance with adjustable thickness of the molar occlusal pad. Because the thickness of the molar occlusal pad is adjustable, the appliance can be adjusted to meet the developmental needs of different stages and types of teeth by simply changing the adjustment pad during the orthodontic process. Compared with existing orthodontic appliances, it has the effects of saving costs, reducing resource waste, and saving time and effort. Attached Figure Description

[0040] The present invention will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0041] Furthermore, for ease of understanding, various components on the drawings have been enlarged (thickened) or reduced (thinned), but this is not intended to limit the scope of protection of this invention.

[0044] The terminology used in this specification is for illustrative purposes and is not intended to limit the invention. It should also be noted that, unless otherwise explicitly stated and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will readily understand the specific meanings of the above terms within the context of this invention.

[0045] Example 1:

[0046] like Figure 1 , Figure 3As shown, the adjustable thickness of the molar occlusal pad in the orthodontic appliance includes a U-shaped occlusal pad 1, which includes an anterior occlusal pad 11 and a molar occlusal pad 12. The outer edges of the occlusal pad 1 extend upward and downward to form labial-buccal barriers 2, and the inner edges of the occlusal pad 1 extend upward and downward to form lingual barriers 3. The occlusal pad 1, labial-buccal barriers 2, and lingual barriers 3 together form an integrated upper and lower orthodontic appliance that adapts to tooth occlusion. The appliance includes a receiving groove 13 located on one side inside the molar occlusal pad 12, and an adjustment pad 7 housed within the receiving groove 13.

[0047] The receiving groove 13 and the adjusting pad 7 housed in the receiving groove 13 are detachably connected and used to adjust the thickness of the molar occlusal pad 12. When the adjusting pad 7 is housed inside the receiving groove 13, the thickness of the molar occlusal pad 12 can be varied.

[0048] Specifically, the thickness of the anterior occlusal pad 11 is the thickness of the occlusal surface when the upper and lower anterior teeth bite together, and the thickness of the anterior occlusal pad 11 is not adjustable. The thickness of the molar occlusal pad 12 is the thickness of the occlusal surface when the upper and lower molars bite together. When the adjusting pad 7 is placed inside the receiving groove 13, the thickness of the molar occlusal pad 12 includes the thickness of the adjusting pad 7 placed inside the receiving groove 13.

[0049] It is conceivable that the orthodontic appliance can also be used when the adjustment pad 7 is not placed inside the receiving slot 13, at which time the thickness of the molar occlusal pad 12 is minimal.

[0050] The top surface of the labial-cheek barrier 2 gradually decreases in height along both sides of the U-shaped occlusal pad 1. The upper top surface 32 of the tongue barrier 3 is a smooth surface, and the lower top surface 33 is a curved surface adapted to the shape of the dental arch in the oral cavity. The labial-cheek barrier 2 and the tongue barrier 3 are used to release the dental arch from the muscles of the lips and cheeks, and reserve appropriate growth space to guide the normal development of the dental arch.

[0051] like Figure 4 As shown, the inner side of the tongue guard 3 includes a protrusion 31 that protrudes towards the teeth. The protrusion 31 fits the tooth surface to adapt to tooth occlusion and provide orthodontic force for orthodontic treatment.

[0052] The middle part of the lip and cheek guard 2 includes an air outlet 4 for correcting mouth breathing.

[0053] like Figure 2 , Figure 3 As shown, the lip and cheek guard 2 includes a lip frenulum buffer zone 21, which is concave and located at the center line of the lip and cheek guard 2. It is used to avoid the lip frenulum inside the mouth and is more comfortable to wear.

[0054] The lip-cheek guard 2 also includes a mandibular buccal frenulum buffer zone 22, which is concave and located in the vestibule on both sides, in the fan-shaped or band-shaped mucosal folds of the lower canine or premolar area, to avoid the buccal frenulum and make it more comfortable to wear.

[0055] The labial-buccal barrier 2 includes a labial-buccal barrier 2 for the upper teeth and a labial-buccal barrier 2 for the lower teeth. The lingual barrier 3 also includes a lingual barrier 3 for the upper teeth and a lingual barrier 3 for the lower teeth. The labial-buccal barrier 2 for the upper teeth, the lingual barrier 3 for the upper teeth, and the occlusal pad 1 together form an upper tooth guide groove 5 for accommodating the occlusion of the upper teeth. Correspondingly, the labial-buccal barrier 2 for the lower teeth, the lingual barrier 3 for the lower teeth, and the occlusal pad 1 together form a lower tooth guide groove (not shown in the figure) for accommodating the occlusion of the lower teeth.

[0056] like Figure 5 As shown, the receiving groove 13 has a rectangular cavity structure. The receiving groove 13 includes a first transverse end face 131 located at the innermost side of the molar occlusal pad 12, a second transverse end face 132 located at the end of the molar occlusal pad 12, and a long end face 133 connecting the first transverse end face 131 and the second transverse end face 132.

[0057] Specifically, the first horizontal end face 131 of the receiving groove is located inside the receiving groove 13 and is a cut surface closed at both ends. The second horizontal end face 132 of the receiving groove is located at the end of the receiving groove 13 and includes an opening surface that is connected and penetrates the outside of the orthodontic appliance.

[0058] In other implementations of this embodiment, the first transverse end face 131 and the long end face 133 of the receiving groove are smooth planes, and the second transverse end face 132 of the receiving groove is an arc surface that conforms to the shape of the dental arch in the oral cavity.

[0059] The straight-line distance between the two sides of the opening of the second horizontal end face 132 of the receiving groove is not greater than the cross-sectional length of the first horizontal end face 131 of the receiving groove.

[0060] In this embodiment, the straight-line distance between the two sides of the opening of the second horizontal end face 132 of the receiving groove is equal to the sectional length of the first horizontal end face 131 of the receiving groove.

[0061] like Figure 3 , Figure 8 As shown, the receiving groove 13 contains an adjusting pad 7 for adjusting the thickness of the molar occlusal pad 12. The shape of the adjusting pad 7 is a rectangular strip that matches the shape of the receiving groove 13. The adjusting pad 7 is made of removable thermoplastic silicone material.

[0062] The adjusting pad 7 includes a first horizontal end face 71 that contacts the first horizontal end face 131 of the receiving groove, a second horizontal end face 72 that is exposed outside the receiving groove 13, and a long end face 73 that cooperates with the long end face 133 of the receiving groove.

[0063] The thickness of the first horizontal end face 71 of the adjusting pad is the same as the thickness of the second horizontal end face 72 of the adjusting pad, and the length of the first horizontal end face 71 of the adjusting pad is the same as the straight-line distance between the two ends of the second horizontal end face 72 of the adjusting pad.

[0064] In other implementations of this embodiment, the first horizontal end face 71 of the adjusting pad is a smooth plane, and its shape matches the shape of the first horizontal end face 131 of the receiving groove 13. The second horizontal end face 72 of the adjusting pad is an arc-shaped curved surface, and its shape matches the shape of the second horizontal end face 132 of the receiving groove 13, which is used to increase the airtightness and continuity during assembly.

[0065] The long end face 73 of the adjusting pad is located in the plane connecting the first horizontal end face 71 and the second horizontal end face 72 of the adjusting pad. The shape of the long end face 73 of the adjusting pad includes a smooth plane that matches the shape of the receiving groove 13.

[0066] In other implementations of this embodiment, the outer edges of the second transverse end face 72 of the adjustment pad extend upward and downward respectively to form adjustment pad baffles 75. The shape of the adjustment pad baffles 75 includes an arc-shaped curved surface that matches the shape of the dental arch in the oral cavity, which is used to increase the comfort when wearing and to facilitate the removal and wearing of the adjustment pad 7.

[0067] Specifically, the height of the adjustment pad baffle 75 is greater than the thickness of the first horizontal end face 71 and the second horizontal end face 72 of the adjustment pad, and less than or equal to the thickness of the molar occlusal pad 12. When the adjustment pad 7 is placed inside the molar occlusal pad 12, the height of the adjustment pad baffle 75 will not exceed the surface of the molar occlusal pad 12. This is to avoid the foreign body sensation when wearing the orthodontic appliance, stimulate saliva secretion, and increase the comfort when wearing it.

[0068] In other implementations of this embodiment, the adjusting pad 7 and the receiving groove 13 are interference fit to increase the stability of the adjusting pad 7 placed in the receiving groove 13.

[0069] Specifically, the thickness of the adjusting pad 7 is set to 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, and 5mm respectively.

[0070] In other implementations of this embodiment, the thickness of the anterior occlusal pad is 3-6 mm, and the thickness of the molar occlusal pad 12 is 2 mm when the adjusting pad 7 is not placed in the receiving groove 13. Adjusting pads 7 of different sizes are placed in the receiving groove 13, and the thickness of the molar occlusal pad 12 is adjusted by replacing various sizes of the adjusting pads 7. The specific values ​​of the thickness of the molar occlusal pad 12 and the thickness of the adjusting pad 7, and the specific values ​​of thickness adjustment when they are combined, are shown in the following table:

[0071]

[0072] Specifically, by using the adjusting pad 7, the thickness of the molar occlusal pad 12 can be adjusted to 2mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, and 7mm, thus providing a wider range of options for adjusting the thickness of the molar occlusal pad 12.

[0073] The molar pad 12 includes a drainage hole 6 for saliva drainage, such as... Figure 11 , Figure 12 As shown, the guide hole 6 is a hole with a certain shape that penetrates the upper and lower surfaces of the molar occlusal pad 12 and communicates with the receiving groove 13. Since the receiving groove 13 contains an adjusting pad 7, the adjusting pad 7 can also be provided with a guide hole 6 in order to increase the drainage effect. No further restrictions are made here.

[0074] Specifically, the drainage hole 6 is located on the occlusal surface of the molar occlusal pad 12 that contacts the highest point of the molar, and is set on both sides of 12 to drain saliva from the oral cavity.

[0075] In other implementations of this embodiment, at least two drainage holes 6 are provided on a molar occlusal pad 12. A multiple number of drainage holes 6 are beneficial for squeezing out saliva from the orthodontic appliance by utilizing the biting force when the teeth are biting. The specific number is not limited here.

[0076] The thickness of the molar occlusal slab 12 can be adjusted by placing the adjusting slab 7. The anterior occlusal slab 11 and the molar occlusal slab 12 can achieve the following three thickness relationships through the adjusting slab 7:

[0077] The thickness of the current occlusal pad 11 is less than that of the molar occlusal pad 12, and it is used to correct anterior open bite malocclusion.

[0078] When the thickness of the anterior occlusal pad 11 is relatively consistent with the thickness of the posterior occlusal pad 12, it is used to correct anterior edge-to-edge malocclusion.

[0079] The thickness of the current occlusal pad 11 is greater than that of the molar occlusal pad 12, and it is used to correct deep overbite malocclusion.

[0080] By adjusting the thickness of the molar occlusal pad 12 by adjusting the pad 7, the thickness relationship between the anterior occlusal pad 11 and the molar occlusal pad 12 of the orthodontic appliance can be adjusted to achieve a thickness difference, thereby effectively controlling the vertical growth of different anterior and posterior tooth areas, and thus improving the problem of vertical developmental deformity of the jawbone.

[0081] Example 2:

[0082] This invention provides an adjustable occlusal pad thickness orthodontic appliance in the molar region. Embodiment two is structurally similar to Embodiment one, as shown below. Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the long end face 133 of the receiving groove on both sides of the receiving groove 13 includes a wave-like cross-section with an uneven shape, which is used to fix the position of the adjusting pad 7 in the receiving groove 13 and prevent it from falling off.

[0083] Specifically, the long end face 133 of the receiving groove is set as a wave-like plane at one end adjacent to the first horizontal end face 131 of the receiving groove, and the long end face 133 of the receiving groove is set as a smooth plane at one end adjacent to the second horizontal end face 132 of the receiving groove, so as to avoid excessive surface resistance of the long end face 133 of the receiving groove 13 when the adjusting pad 7 is placed, or to avoid increasing the difficulty of placing the adjusting pad 7.

[0084] Specifically, the wave-like shape of the long end face 133 of the receiving groove is a description of the unevenness of the surface of the long end face 133 of the receiving groove, and does not limit the shape of the long end face 133 of the receiving groove by describing the shape of the wave-like shape. The shape of the long end face 133 of the receiving groove can be set as any form of uneven shape such as stepped, elliptical, or square, which are all within the scope of protection of this invention.

[0085] like Figure 9 As shown, the adjustment pad 7 of the molar occlusal pad thickness adjustable induction orthodontic appliance described in this embodiment is similar in structure to that of Embodiment 1. The difference between this embodiment and Embodiment 1 is that the long end face 73 of the adjustment pad includes a wave-shaped plane that fits the shape of the long end face 133 of the receiving groove 13, so as to make the adjustment pad 7 fit more snugly in the receiving groove 13 of this embodiment and increase the stability of the adjustment pad 7 in the receiving groove 13.

[0086] Example 3:

[0087] This invention provides an adjustable occlusal pad thickness orthodontic appliance in the molar region. Embodiment three is structurally similar to Embodiment one, as shown below. Figure 7 As shown, the difference is that the receiving groove 13 has protruding portions on both sides, receiving groove limiting angle 134, which is used to limit the position of the adjusting pad 7 and prevent the adjusting pad 7 from falling out of the receiving groove 13.

[0088] Specifically, the limiting angle 134 of the receiving groove is located inside the receiving groove 13, is perpendicular to the long end face 133 of the receiving groove, and is not in the same plane as the second horizontal end face 132 of the receiving groove. The limiting angle 134 of the receiving groove is located at the interface between the long end face 133 of the receiving groove and the second horizontal end face 132 of the receiving groove, and is adjacent to the second horizontal end face 132 of the receiving groove.

[0089] In other implementations of this embodiment, the limiting angle 134 of the receiving groove is a protruding part within the receiving groove 13. The plane of the limiting angle 134 of the receiving groove can be set to various shapes such as a smooth plane, a curved surface, or a stepped surface. The shape of the limiting angle 134 of the receiving groove is set to limit the position of the adjusting pad 7 within the receiving groove 13 when it is convenient to put on and take off the adjusting pad 7. Therefore, the specific shape is not further limited here.

[0090] The planar length of the limiting angle 134 of the receiving groove is greater than or equal to 1 mm and less than the vertical distance between the two ends of the second horizontal end face 132 of the receiving groove.

[0091] The difference between the receiving groove 13 described in this embodiment and that in embodiment one is that the straight distance between the two sides of the opening of the second horizontal end face 132 of the receiving groove is less than the cross-sectional length of the first horizontal end face 131 of the receiving groove. By utilizing the length difference between the first horizontal end face 131 and the second horizontal end face 132 of the receiving groove, the receiving groove 13 presents an overall shape that is wider inside and narrower outside, which is used to fix the adjusting pad 7 placed in the receiving groove 13.

[0092] like Figure 10 As shown, the adjusting pad 7 of the molar occlusal pad thickness adjustable guiding orthodontic appliance described in this embodiment is similar in structure to that of Embodiment 1. The difference is that the adjusting pad 7 also includes an adjusting pad limiting angle 74. The adjusting pad limiting angle 74 is located at the interface between the long end face 73 and the second horizontal end face 72 of the adjusting pad and is concave. The adjusting pad limiting angle 74 matches the protruding shape of the receiving groove limiting angle 134 in the receiving groove 13. It is used to place inside the receiving groove 13, so that the adjusting pad 7 is more closely fixed in the receiving groove 13 of this embodiment, and the position of the adjusting pad 7 in the receiving groove 13 is better fixed.

[0093] like Figure 12 As shown, the difference between the adjustment pad 7 in this embodiment and the first embodiment is that the adjustment pad 7 does not include the adjustment pad baffle 75, the second horizontal end face 72 of the adjustment pad is the end of the adjustment pad 7, the adjustment pad 7 is assembled in the orthodontic receiving groove 13, the shape of the second horizontal end face 72 of the adjustment pad is a wave-like shape that matches the shape of the second horizontal end face 132 of the orthodontic receiving groove, and the plane of the second horizontal end face 72 of the adjustment pad and the plane of the second horizontal end face 132 of the receiving groove are located in the same vertical plane.

[0094] The working principle of the bite-inducing orthodontic appliance described in this application is mainly as follows:

[0095] Since the thickness of the anterior occlusal slat is fixed, the thickness of the molar occlusal slat can be adjusted within a certain range by adjusting the slats. In the actual treatment process, the thickness relationship between the anterior and molar occlusal slats can be differentiated according to the different needs of the patient's tooth height adjustment and the different height requirements of the molar occlusal slat at different treatment stages. This allows the patient to meet the different needs of the anterior and posterior occlusal slat thickness at different stages with only one appliance. Therefore, the aforementioned molar occlusal slat thickness adjustable guiding appliance can better control and adjust the vertical development of the patient's maxilla and mandible, thereby controlling the vertical growth and development of the jawbone and preventing and treating various malocclusion problems.

[0096] The specific embodiments of the present invention have been described in detail above.
