Under the general condition, in the orthodontic process, the wearer often needs to finish correcting by wearing a series of orthodontic appliances, at the moment, the correcting process needs to divide a plurality of correcting stages according to the current tooth state and the final tooth correcting state of the wearer, namely, a plurality of target dentition correcting stages are divided, and the wearer finishes gradually correcting by wearing a next target dentition correcting appliance different from the current dentition shape.

Fig. 1 is a schematic top view of a dental appliance for enhancing orthodontic efficacy of the present invention, and as shown in fig. 1, the dental appliance for enhancing orthodontic efficacy comprises a mouthpiece body 1, a cheek shield 2, and a connecting member 3 connected between the mouthpiece body 1 and the cheek shield 2.

The tooth socket body 1 comprises a high polymer material shell matched with the shape of the next target dentition of a wearer, the appearance of the tooth socket body 1 is of a U-shaped transparent three-dimensional thin-wall type cavity structure, and the interiors of cavities are communicated with each other and used for correcting teeth through micro elastic deformation.

The buccal labial side of the tooth socket body 1 is provided with a labial cheek screen 2, the labial cheek screen 2 is a U-shaped screen-shaped structure and is used for matching with the shape of the dentition of the wearer with the shape of the tooth socket body 1, so that the labial cheek screen 2 can better act on the dental arch of the wearer by pushing and pulling force to assist in correcting the dentition.

The material of the lip and cheek screen 2 comprises a metal or high polymer material and other materials with small elastic deformation amount, and the material rigidity of the lip and cheek screen 2 is greater than that of the mouthpiece body 1 and is used for resisting deformation caused by isolating the muscle strength of the lip and cheek side of a wearer.

Specifically, the labial and buccal screens 2 extend from labial anterior teeth to buccal molars, so that the labial and buccal screens 2 surround the labial and buccal sides of the U-like shaped mouthpiece body 1, namely the labial and buccal screens 2 are covered on the labial and buccal sides of the mouthpiece body 1 in a U-like shape, and are used for isolating the force of buccal muscles of a wearer on teeth to be corrected and eliminating the adverse pressure influence of buccal muscles at the molars on dental arches.

Fig. 2 is a schematic sectional view of a dental apparatus for enhancing correction efficacy in a direction a-a in fig. 1, as shown in fig. 2, the labial and buccal screens 2 have an extending distance in a vertical direction with respect to an occlusal plane, and the labial and buccal screens 2 at least partially or completely cover the mouthpiece body 1 in the vertical direction, so that the sections of the labial and buccal screens 2 in the vertical direction are elongated for effectively stretching the muscles of the labial and buccal muscles and isolating the muscle pressure of the muscles of the buccal muscles.

Wherein, the vertical direction is based on the occlusal plane as a reference, and the direction approximately perpendicular to the occlusal plane is also the vertical direction specified in the present application.

The occlusal plane is an imaginary plane formed from the mesial incisor angle of the maxillary central incisor to the mesial buccal cusp of the bilateral first molars, substantially bisecting the intermaxillary distance.

Specifically, when the lip and cheek screens 2 extend to the side of the lip and cheek covering most of the mouthpiece body 1 in the vertical direction with the occlusal plane as a reference, when the mouthpiece body 1 worn on the upper jaw and the mouthpiece body 1 worn on the lower jaw perform opening and closing movements, such as speaking and drinking, the lip and cheek screens 2 are independent of each other and do not interfere with each other, so as to improve the wearing comfort, and have the advantage of flexible opening and closing while providing sufficient supporting force.

When the cheek shield 2 worn on the upper teeth extends to the mandibular dentition area in the vertical direction with reference to the occlusal plane, the cheek shield 2 is used to expand the range of shielding the muscles on the cheek side, and the cheek shield 2 of the lower jaw may not be designed.

It is conceivable that, in some embodiments, the lip and cheek shields 2 worn on the lower jaw teeth may also extend to the upper jaw dentition area or the tooth root area in the vertical direction, and the extending distance of the lip and cheek shields 2 worn on the upper and lower jaws may be adjusted according to the wearer's condition, only the lip and cheek shields 2 may extend at least to partially or completely shield the mouthpiece body 1 in the vertical direction with the occlusal plane as the reference, and the specific values are not further limited herein.

The mouthpiece body 1 and the lip and cheek screen 2 are connected into a whole through the connecting piece 3, and in addition, a 3D printing technology or a mixed material 3D printing technology can be adopted for integral forming, so that the simplicity of the structure is improved.

The connecting piece 3 is a connecting structure between the tooth socket body 1 and the lip and cheek screen 2 and is used for conducting pushing and pulling force applied to the tooth socket body 1 by the lip and cheek screen 2 and correcting the expansion or contraction of the arch in the back tooth area.

The connecting piece 3 has a thickness parallel to the occlusal plane direction, and the thickness is smaller than the limit that can be accommodated in the oral cavity of a wearer, so that a distance parallel to the occlusal plane direction is formed between the mouthpiece body 1 and the buccal labial screen 2, and the thicker the distance, the closer the buccal labial screen 2 is contacted with the muscularis mucosa tissues at the buccal labial side, so as to reduce the muscular strength of the buccinator on the teeth and increase the acting force of the labial muscle on the teeth.

Preferably, the thickness of the connecting piece is 1mm-5 mm.

The utility model has the following function principle:

when the tooth socket body 1 is used for tooth correction, the labial and buccal screens 2 transmit the pulling force or the opposite pushing force in the buccal direction of the tooth socket body 1 through the connecting pieces 3, and the pulling force or the opposite pushing force acts on teeth or dentition through the tooth socket body 1 again to be used for arch expansion or arch contraction in a rear tooth area.

The buccal and labial screen 2 is arranged on the buccal and labial sides in the oral cavity, so that abnormal pressure of buccal muscles on dental arches can be eliminated, and dentition and alveolar bones can grow to normal positions.

While the utility model has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit of the utility model, and it is intended to claim all such changes and modifications as fall within the scope of the appended claims.
