Masticatory orthodontic correction device

A masticatory orthodontic correction device adapted to use occlusal loads generated during mastication as a correction force to achieve orthodontic correction for a patient having a first tooth of the maxillary or mandibular dental arch in malposition, the masticatory orthodontic correction device comprising:

• a first correction unit with a rigid body configured to be removably worn on the maxillary dental arch of the patient during mastication, wherein when worn, a shape of the first correction unit is maintained without deformation when accommodating teeth, and the first correction unit has a first occlusal part;
• a second correction unit with a rigid body configured to be removably worn on the mandibular dental arch of the patient during mastication, wherein when worn, a shape of the second correction unit is maintained without deformation when accommodating teeth, and the second correction unit has a second occlusal part corresponding to the first occlusal part, wherein the first and second occlusal parts are exposed and face each other;
• a first recess formed in the first or second correction unit and corresponding to the first tooth, wherein a shape of the first recess leaves a first space between the first recess and the first tooth when the masticatory orthodontic correction device is worn by the patient, arranged such that the first tooth can move in the first recess when the first and second correction units are worn during mastication;
• a buffering member disposed in the first space and configured to transmit and buffer the occlusal loads generated during mastication between the first recess and the first tooth, wherein the buffering member is deformable and arranged such that when the first and second correction units are worn during mastication, the buffering member deforms and contacts the first tooth over an area, wherein the buffering member is made of an elastic material;
• and
• a plurality of second recesses formed in the first and second correction units, the plurality of second recesses correspond to a plurality of second teeth of the maxillary and mandibular dental arches of the patient not requiring orthodontic correction, wherein shapes of the second recesses respectively conform to the second teeth with no buffering member disposed between each of the second recesses and the respective second tooth, arranged such that a part of the occlusal loads are transferred from the first and second correction unit to the second teeth during mastication while the masticatory orthodontic correction device is worn by the patient,
• wherein the first and second occlusal parts have shapes configured to establish functional occlusion, and the first correction unit has a left buccal part, a right buccal part, and a plurality of limit parts formed on the left and right buccal parts, and the second correction unit has a left buccal surface and a right buccal surface, wherein the limit parts each have a lingual guiding surface arranged to contact the left or right buccal surfaces and configured to limit a movement range of the second correction unit relative to the first correction unit in a lateral direction during mastication.
