[0020] The above and other features of this application will be further described below with reference to the accompanying drawings and their detailed description. It should be understood that these drawings only illustrate several exemplary embodiments according to this application and should not be considered as limiting the scope of protection of this application. Unless otherwise specified, the drawings are not necessarily to scale, and similar reference numerals denote similar parts.
[0021] Figure 1A A dental training device according to one embodiment of this application is shown; and
[0022] Figure 1B It shows from another perspective Figure 1A The dental training shown. Detailed Implementation
[0023] The following detailed description incorporates the accompanying drawings, which form part of this specification. The illustrative embodiments mentioned in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art will understand, based on the teachings of this application, that many other embodiments can be employed and various changes can be made to the described embodiments without departing from the spirit and scope of this application. It should be understood that the various aspects of this application illustrated herein can be arranged, substituted, combined, separated, and designed in many different configurations, all of which are within the scope of this application.
[0024] One aspect of this application provides a dental training device comprising a U-shaped base plate. In use, the patient's upper and lower jaw dentitions are located on opposite sides of the U-shaped base plate. One of the opposite sides of the U-shaped base plate is integrally formed with a jaw position induction feature, which can guide the patient to move and hold the corresponding dentition to that position, thereby correcting the relative positional relationship of the upper and lower jaws along the anterior-posterior direction.
[0025] Please refer to Figure 1A and Figure 1B This illustrates a dental training device 100 according to one embodiment of the present application.
[0026] The dental training instrument 100 includes a U-shaped base plate 101, which forms a first surface 1031 on a first side 103 corresponding to the maxillary dentition and a second surface 1051 on a second side 105 corresponding to the mandibular dentition.
[0027] The first surface 1031 has a raised edge on the lip / cheek side to form a maxillary lip guard 1033, and a raised edge on the tongue side to form a maxillary lingual guard 1035. The top of the maxillary lingual guard 1035 extends inward to form a palatal guard 1037, and at least one tongue training induction feature 1039 is formed on each of the left and right sides of its tongue-side surface, which are symmetrically distributed. The patient performs tongue training by licking the tongue training induction feature 1039 with the tip of the tongue.
[0028] In one embodiment, the maxillary labial barrier 1033 and the maxillary lingual barrier 1035 may be continuous barriers, which are used to separate the maxillary dentition from the lips, cheeks and tongue, respectively.
[0029] The tongue training induction feature 1039 is located in the segment corresponding to teeth 4 through 8. The inventors of this application have experimentally discovered that tongue training induction features located in the posterior tooth region can effectively correct the bad habit of tongue thrusting. This application adopts a commonly used tooth numbering method in the art. For a normal dentition, each tooth is numbered from 1 to 8 from the middle to both sides. For example, the rightmost central front tooth in this dentition is tooth number 1, the adjacent front tooth to its right is tooth number 2, and the last tooth is tooth number 8.
[0030] The tongue training induction feature 1039 can be a raised or recessed feature, such as a protrusion, as long as it can be perceived by the tongue.
[0031] The maxillary labial guard 1033, the maxillary lingual guard 1035, and the first surface 1031 define a U-shaped groove 1041, which fixedly houses the occlusal module 1043. The occlusal module 1043 is recessed inward to form a cavity 1045 for accommodating the maxillary dentition, and its geometry can match the maxillary dentition under the first tooth layout.
[0032] The first tooth layout can be the patient's current tooth layout or the desired tooth layout. When the first tooth layout is the patient's current tooth layout, during dental training using the dental training instrument 100, the patient's maxillary dentition can be relatively fixed to the dental training instrument 100, facilitating dental training. When the first tooth layout is the desired tooth layout, in addition to fixing the patient's maxillary dentition to the dental training instrument 100, the dental training instrument 100 can also reposition the patient's maxillary dentition from the current tooth layout to the desired tooth layout.
[0033] In one embodiment, the engagement module 1043 is a separate component that can be fixed to the substrate 101 by means of: a concave-convex mating structure, bonding, welding, fusion, and pressure fitting, etc.
[0034] In one embodiment, the elastic modulus of the material of the engagement module 1043 may be lower than that of the material of the substrate 101.
[0035] In one embodiment, the engagement module 1043 may be made of silicone, rubber, or TPU (Thermoplastic Polyurethane).
[0036] In one embodiment, the substrate 101 may be made of polycarbonate (PC), poly(ethyleneterephthalateco-1,4-cylclohexylenedimethylene terephthalate) (PETG), polyamide (PA), polyetheretherketone (PEEK), polypropylene (PP), acetone butadiene styrene (ABS), polyoxymethylene (POM), metal, carbon fiber, or glass fiber.
[0037] In addition to the occlusal module 1043 fixed to the first side of the base plate 101, any other suitable structure can be used to fix the relative position between the maxillary dentition and the dental training instrument 100. For example, the width of the U-shaped groove 1041 defined by the maxillary labial guard 1033, the maxillary lingual guard 1035, and the first surface 1031 corresponds to the width of the maxillary dentition to limit the relative movement of the maxillary dentition and the dental training instrument 100 in the anterior-posterior direction. Alternatively, additional structures can protrude from the first surface 1031 to limit the anterior-posterior movement of the maxillary dentition relative to the dental training instrument 100, such as the walls of the maxillary labial guard 1033 and the maxillary lingual guard 1035.
[0038] The second surface 1051 of the second side 105 of the substrate 101 forms a jaw position induction feature 1053 at a predetermined position for inducing the patient to move and hold the mandibular dentition therein in order to correct the relative positional relationship between the maxilla and mandible.
[0039] Jaw position induction feature 1053 can be any applicable structure, as long as it can be sensed when the patient's mandibular dentition moves to that location.
[0040] In one embodiment, the jaw positioning feature 1053 may be a shallow groove formed on the second surface 1051, which can be sensed when the patient's mandibular dentition slides into the groove. In one embodiment, the length of the groove is sufficient for tooth #1 to slide in. In one embodiment, the geometry of the groove may conform to the corresponding teeth of the patient's mandibular dentition. In yet another embodiment, the inner surface of the groove may also be a smooth surface.
[0041] In another embodiment, the jaw position induction feature may also be at least one protrusion provided on the second surface 1051, such as two protrusions, three protrusions, four protrusions, etc. During training, the mandibular dentition slides along the anteroposterior direction on the second surface 1051 until the corresponding teeth touch or just pass over these protrusions, thus holding the mandibular dentition in this position for jaw position correction training.
[0042] In another embodiment, the jaw position induction feature may also be a raised strip provided on the second surface 1051. During training, the mandibular dentition slides along the front-back direction on the second surface 1051 until the corresponding tooth touches or just passes the raised strip, thus holding the mandibular dentition in this position for jaw position correction training.
[0043] In one embodiment, two or more mandibular position guidance features can be provided at different positions along the anterior-posterior direction on the second surface 1051 for progressive training in correcting mandibular position. For example, if the desired mandibular advance is 6mm, mandibular position guidance features can be provided at 3mm and 6mm of the advance position, allowing the patient to first use the mandibular position guidance feature at 3mm of the advance position for mandibular position correction training. Once the mandibular position is corrected to a certain extent, the mandibular position guidance feature at 6mm of the advance position can then be used for further correction training. This makes it easier for patients to adapt to mandibular position correction training.
[0044] When the jaw position induction feature is located on the second side 105 of the dental training instrument 100, during the mandibular dentition movement training, to prevent the maxillary dentition from moving relative to the dental training instrument 100 in a direction opposite to the correction direction of the mandibular dentition, and to maintain the correct relative positional relationship between the maxillary and mandibular dentitions during jaw position correction training, in the above embodiment, a structure for fixing the relative positional relationship between the maxillary dentition and the dental training instrument 100 is provided on the first side 103 of the dental training instrument 100. In another embodiment, a dentition limiting structure provided on the first side 103 of the dental training instrument 100 can replace the dentition fixing structure.
[0045] For example, in mandibular preposition training, the dentition limiting structure prevents the maxillary dentition from moving posteriorly relative to the dental training instrument 100. During training, when the maxillary dentition is against the dentition limiting structure and the mandibular dentition is in a jaw position induction characteristic, the relative positional relationship between the maxilla and mandible is the relative positional relationship required for training. At this time, the maxillary lingual stop 1035 can serve as the dentition limiting structure.
[0046] Similarly, for mandibular posterior guidance training, the dentition limiting structure prevents the maxillary dentition from moving forward relative to the dental training instrument 100. During training, when the maxillary dentition abuts against the dentition limiting structure and the mandibular dentition is in a jaw position induction characteristic, the relative positional relationship between the maxilla and mandible is the relative positional relationship required for training. At this time, the maxillary labial stop 1033 can serve as the dentition limiting structure.
[0047] In the above embodiments, the jaw position induction feature is set on the side of the dental training instrument corresponding to the mandibular dentition. In fact, the jaw position induction feature can also be set on the side of the dental training instrument corresponding to the maxillary dentition.
[0048] For example, a dentition fixation structure can be provided on the second side 105 of the dental training instrument 100 to keep the relative position of the mandibular dentition with respect to the dental training instrument 100 unchanged. By moving the mandibular dentition, the dental training instrument 100 is moved relative to the maxillary dentition until the corresponding teeth of the maxillary dentition are at the position induction feature.
[0049] For example, a dentition limiting structure can be provided on the second side 105 of the dental training instrument 100. The mandibular dentition moves against this dentition limiting structure in the direction of jaw position correction, thereby causing the dental training instrument 100 to move relative to the maxillary dentition until the corresponding teeth of the maxillary dentition are at the jaw position induction feature. In this case, for mandibular anterior guidance training, a mandibular labial guard 1055 can be used as the dentition limiting structure, wherein the mandibular labial guard 1055 protrudes from the labial side of the second surface 1051. For mandibular posterior guidance training, a mandibular lingual guard (not shown in the figure) can be used as the dentition limiting structure, wherein the mandibular lingual guard protrudes from the lingual side of the second surface 1051.
[0050] It is understood that when using the dental training instrument 100, the patient's upper and lower dentitions bite onto the first side 103 and the second side 105 of the dental training instrument 100, respectively, and the dentition corresponding to the side with the jaw position guidance feature can move relative to the dental training instrument 100 along the surface of that side to allow the dentition to move to the jaw position guidance feature.
