Example 1

Referring to fig. 1, the present embodiment provides a shell-shaped dental appliance 100 for adjusting the jaw relation of a deviated jaw patient, wherein the shell-shaped dental appliance 100 includes a shell-shaped body 11 accommodating a plurality of teeth, and,

at least a part of the posterior dental area on at least one of the left and right sides of the shell-shaped body 11 is provided with a corrective part protruding in the opposite jaw direction on the buccal side or lingual side to adjust the relative position of the upper and lower jaws, for example, in the shell-shaped dental appliance 100 shown in fig. 1, the corrective part 12 is provided on a part of the posterior dental area on the right side of the shell-shaped body and is located on the buccal side; the correcting part arranged on the buccal side surface or the lingual side surface comprises an acting end; when the upper and lower jaws are occluded, the active end covers the buccal or lingual side of at least some of the teeth in the posterior dental area of the jaw, for example in the occlusion shown in fig. 2, the active end 121 of the orthotic device 12 covers the buccal side of the corresponding tooth in the jaw, and the active end (e.g., the active end 121) interacts with the opposing jaw such that at least some area of the patient's face below the bridge of the nose gradually changes from the first position to the second position. As used herein and elsewhere in the present disclosure, "left or right" refers to the left and right sides of the human jaw, rather than the left or right portions as shown in the drawings, after the appliance is worn over the teeth. Further, the active end may be a part or all of the orthotic.

Wherein the "posterior dental zone" is defined according to the classification of teeth, including premolars and molars, shown as teeth 4-8 by FDI notation, in pages 36-38 of the "introduction to oral medicine" published by Beijing university medical Press. The posterior dental zone of the shell-shaped dental appliance may be used to accommodate first premolars, second premolars, first molars, second molars and third molars of the maxillary or mandibular teeth. At least a portion of the posterior dental area of the shell-like body may be a portion that receives any one or more of the first premolar, the second premolar, the first molar, the second molar, and the third molar.

Specifically, in fig. 1, the shell-like body 11 is provided with a correcting portion 12 protruding in the opposite jaw direction to adjust the relative position of the upper and lower jaws, on a buccal side surface of a part of the posterior dental area on one side (wherein a part of the posterior dental area may be a part of the posterior dental area of the shell-like body that wraps a part of the teeth of the posterior dental area). When the upper and lower jaws are occluded, the active end 121 covers the buccal side of a portion of the teeth of the posterior mandibular area and interacts with the opposing jaw such that at least a portion of the area of the patient's face below the bridge of the nose gradually changes from a first position to a second position. More specifically, when the shell-like body 11 is worn on the maxillary teeth, the correcting portion 12 provided thereon is provided to project in the mandibular direction and is located to project in the mandibular direction at the buccal side surface of a part or the entire posterior dental area of the shell-like body 11, and when the upper and lower jaws interact, the action end 121 provided on the shell-like appliance worn on the upper jaw covers the buccal side surfaces of a part or the entire posterior dental area teeth in the mandibular posterior dental area to push or produce a relative movement of the mandibular buccolingual position which is a gradual change from a deviated symmetrical position to the normal occlusal position of the upper and lower jaws.

In other embodiments, the orthodontic part 12 and/or the action end 121 may be further provided on a part of or the entire posterior dental area on one side of the shell-like body 11 with a lingual side surface thereof protruding in a mandibular direction, and the action end provided on the shell-like dental appliance worn on the upper jaw is overlaid on lingual side surfaces of a part of or the entire posterior dental area teeth of the mandibular posterior dental area when the upper and lower jaws interact to push or produce a relative movement of a mandibular-buccal-lingual position which is gradually changed from a deviated symmetrical position to a normal occlusal position of the upper and lower jaws.

In other embodiments, the buccal orthodontic part 12 provided thereon is provided to protrude in the maxillary direction at a buccal side of a part or the whole of the posterior dental area of the shell-shaped body 11 when the shell-shaped body 11 is worn on the lower jaw teeth, and is provided to protrude in the maxillary direction at a buccal side thereof, and when the upper and lower jaws interact with each other, the lower shell-shaped dental appliance is provided with an action end covering a buccal side of a part or the whole of the teeth of the posterior dental area of the upper jaw to push or generate a relative movement of a mandibular buccal-lingual position which is gradually changed from a deviated symmetrical position to a normal occlusal position of the upper and lower jaws.

In further embodiments, the lingual corrective part 12 provided thereon is provided to project in the maxillary direction when the shell-like body 11 is worn on the mandibular teeth, and is specifically provided to project in the maxillary direction on the lingual side of a part or the entire posterior area of the shell-like body 11, and the lower and upper jaws are interacted with each other such that the action end provided on the shell-like dental appliance of the lower jaw covers the lingual side of a part or the entire posterior teeth of the maxillary posterior area to push or produce a relative movement of the mandibular-buccal-lingual position which is a gradual change from a deviated symmetrical position to the normal occlusal position of the lower and upper jaws.

The position and the mode of the correction unit 12 in each of the different embodiments described above can be selected in a targeted manner for the actual case of the patient.

In addition, a correction portion protruding toward the jaw may be further provided on a buccal side surface or a lingual side surface of a partial or whole region of the posterior dental area on both sides of the shell-shaped body 11, such as a shell-shaped dental appliance structure shown in fig. 3, wherein the left dental jaw is provided with the correction portion 12' on the lingual side surface, the right dental jaw is provided with the correction portion 12 ″ on the buccal side surface, and the left and right sides of the shell-shaped dental appliance are provided with the correction portions to more effectively fix the relative positions of the upper and lower jaws, so that the occlusal relationship between the upper and lower jaws is more stable when the upper and lower jaws are used for partial jaw correction, and the effect is stronger.

Wherein the gradual transition from the first position to the second position as described herein enables the patient's face to be symmetrical or substantially symmetrical at least in the portion below the bridge of the nose. This can solve the following problems: for a deviated jaw patient, after a wound exists on one side of a tooth, the other side of the tooth is chewed for a long time, so that the facial surfaces of the two sides are asymmetric, and the condyles of the two sides are asymmetric.

Further, the correction of the contact between the correction portions (e.g.,

correction portions

12, 12', 12 ") and the buccal or lingual side of the jaw teeth described herein causes the shorter side of the patient's facial surface to be stretched to be symmetrical or substantially symmetrical to the longer side of the facial surface, such arrangement can gradually correct the side deviating from the normal occlusion position to the normal occlusion position, and simultaneously promote the growth of the condyles on the shorter side of the facial surface to be consistent with the condyles on the opposite side, so that the condyles on both sides tend to be symmetrical after correction, and the relationship among facial surface, joints and jaw can be synchronously adjusted.

Specifically, for example, at least a part of the area below the nose bridge of the face of the patient comprises lips, and the correction adjustment mode can improve the face of the patient, not only correct the bad habits of the patient, but also enhance the self-confidence of the patient.

In addition, at least part of the area below the nose bridge of the face of the patient comprises double cheeks, the face of the deviated jaw patient is usually asymmetric, namely one cheek is longer, and the other cheek is shorter, so that certain influence is caused on the psychology and physiology of the patient, and the shell-shaped dental appliance provided by the embodiment can adjust the relative position and symmetry of the double cheeks of the patient.

In the shell-shaped dental appliance, the acting end further comprises the following two surfaces: the lingual side of the action end and the buccal side of the action end, when worn in the upper jaw, are exemplified by a shell-shaped dental appliance:

in one embodiment, when the correction portion is disposed on the buccal side of a part or all of the posterior dental area of the shell-shaped body, the structure shown in fig. 4 is shown, in which the acting lingual side is marked as 121a and the acting buccal side is marked as 121b, the acting lingual side 121a extends along the buccal cusp position of the teeth in the posterior dental area of the shell-shaped body 11 in the opposite jaw direction, and the acting buccal side 121b extends along the buccal side of the posterior dental area of the shell-shaped body 11; more specifically, the action end 121 may be a vacuole structure in which the correction portion or the shell-like body protrudes in the opposite jaw direction, and the vacuole structure is formed by connecting an action-end lingual side 121a and an action-end buccal side 121b, and since the width of the upper jaw of the normal tooth in the lateral direction of the buccal-lingual side of the arch is larger than the width of the lower jaw in the lateral direction of the buccal-lingual side of the arch, the action-end buccal side 121b extends along the buccal side of the posterior dental area of the shell-like body 11, and the action-end lingual side 121a extends in the opposite jaw direction along the position of the buccal cusps of the teeth in the posterior dental area of the shell-like body 11, in such a manner that the action end 121 can cover the buccal side of at least a part of the teeth in the posterior dental area of the lower jaw in the normal occlusion relationship, and when worn by an offsite patient, the action end 121 can effectively correct the lower jaw deviated from the normal position to the normal position.

In another embodiment, when the correction portion is provided on the lingual side of a part or all of the posterior dental area of the shell-shaped body, the correction portion 12' provided on the lingual side of the left dental jaw as shown in fig. 3 includes an action buccal side 121b ' and an action lingual side 121a ', as indicated by reference in fig. 4, the action buccal side 121b ' extends in the opposite jaw direction along the lingual apex position of the teeth of the posterior dental area of the shell-shaped body, and the action lingual side 121a ' extends along the lingual side of the posterior dental area of the shell-shaped body; more specifically, the working end may be a correction portion or a vacuole structure in which the shell-like body protrudes in the opposite jaw direction, and the vacuole structure is composed of a working-end lingual side surface 121a 'and a working-end buccal side surface 121b', and since the width of the upper jaw of the normal tooth in the lateral direction of the arch buccal lingual side is larger than the width of the lower jaw in the lateral direction of the arch buccal lingual side, the working-end lingual side surface 121a 'extends along the lingual side surface of the posterior dental area of the shell-like body, and the working-end buccal side surface 121b' extends in the opposite jaw direction along the position of the lingual cusp of the teeth in the posterior dental area of the shell-like body, the working end can cover the lingual side surface of at least a part of the teeth in the posterior dental area of the lower jaw in the normal occlusion relationship, and when worn by an offshoot patient, the working end can effectively correct the lower jaw deviated from the normal position to the normal position.

Further, the correction portion is provided with a guide surface for guiding the jaw to a stable occlusion position, which will be described by way of example when the shell-shaped dental appliance is worn on the upper jaw:

in some embodiments, as shown in the shell-shaped dental appliance of fig. 1 and 5, when the correction portion 12 is provided on a buccal side surface of a part or all of the posterior dental area of the shell-shaped body and the action-side lingual surface 121a extends in the opposite jaw direction along a buccal cusp position of teeth in the posterior dental area of the shell-shaped body 11, the action-side lingual surface 121a has a guide surface for guiding the correction portion to interact with the opposite jaw to a stable occlusion position, as shown in fig. 5; more specifically, for the deviated jaw patient, the common condition is that when the patient is in an opening, the midline of the upper jaw and the lower jaw is basically symmetrical, and in the closed occlusion process, the occlusion track is deviated, so that the occlusion relation is dislocated; when the guide surface is arranged on the acting end lingual side 121a, the lower jaw slides on the guide surface or is driven by the guide surface to engage up and down at a normal position and stabilize the occlusion, so that the reconstruction of the occlusion relationship of the patient can be quickly guided.

In other embodiments, as shown in fig. 3 and 4, when the correction portion 12' is provided on the lingual side of part or all of the posterior teeth area of the shell-shaped body, and the acting buccal side 121b ' extends in the opposite jaw direction along the lingual apex position of the teeth in the posterior teeth area of the shell-shaped body, the acting buccal side 121b ' has a guide surface for guiding the correction portion to interact with the opposite jaw to a stable occlusion position; more specifically, for the deviated jaw patient, the common condition is that when the patient is in an opening, the midline of the upper jaw and the lower jaw is basically symmetrical, and in the closed occlusion process, the occlusion track is deviated, so that the occlusion relation is dislocated; when the guide surface is arranged on the buccal side surface of the acting end, the lower jaw slides on the guide surface or is driven by the guide surface to engage up and down at a normal position and stabilize the occlusion, so that the reconstruction of the occlusion relation of the patient can be quickly guided.

More specifically, for example, the guide surface is a guide ramp or guide arc structure that guides the correction portion to interact with the opposing jaw to a stable bite position, as shown in fig. 1, 2 and 3, 4, in order to allow the lower jaw to more quickly move into the normal bite position, and more specifically, the guide ramp or guide arc structure may be a smooth flat or curved surface.

Furthermore, the geometry of the cavity of the shell-like body 11 housing the plurality of teeth may also have the function of repositioning the teeth, so that the plurality of teeth are positioned from a first arrangement to a second arrangement different from the first arrangement. For a deviated jaw patient, the jaw relation is not only inconsistent, but also the occlusion relation between upper and lower teeth can be inconsistent due to the inconsistency of the upper and lower jaw relation for a long time, the stable occlusion relation of the upper and lower jaws is relative to the fossa acustica under the normal condition, the normal occlusion relation is broken for the deviated jaw patient, but on the premise of chewing, the deviated occlusion relation can be reestablished, and the incorrect occlusion relation established for a long time can cause the abrasion and position adjustment of the teeth, so that the shell-shaped tooth appliance provided in the embodiment aims at not only needing the adjustment of the jaw relation but also needing the adjustment of the tooth position for the deviated jaw patient. The plurality of teeth are positioned from the first layout to a second layout different from the first layout, the first layout may be an initial tooth layout of the patient, or a layout at any intermediate position in the correcting process, and the second layout may be a final correcting target layout of the patient, or a second layout which is closer to a target correcting position after the first layout.
