  • Publication number: 20170258554
    Abstract: A removable orthodontic correction device includes a first correction unit, a second correction unit, and several elastic members. The first correction unit is configured to be removably worn on the anterior teeth of the maxillary or mandibular dental arch of a patient and has several first connection parts formed thereon. The second correction unit is configured to be removably worn on the posterior teeth of the same maxillary or mandibular dental arch of the patient and has several second connection parts formed thereon. The elastic members couple the first connection parts to the second connection parts. Thus, the elastic force of the elastic members drives the first correction unit to retract toward the second correction unit, to achieve en masse retraction and intrusion of the anterior teeth during space closure in the treatment of dental protrusion.

  • Publication number: 20160310237
    Abstract: A masticatory orthodontic correction device includes at least one correction unit with a rigid body. The correction unit is worn on a maxillary or mandibular dental arch of a patient during mastication, and the shape of the correction unit is maintained without deformation when accommodating teeth. At least one first recess is formed in the correction unit and has a shape which leaves a first space around a first tooth of the maxillary or mandibular dental arch. The first tooth is a tooth in malposition requiring correction, and the first space allows the first tooth to move therein during mastication. At least one buffering member is formed in the first space for transmitting and buffering force between the first recess and the first tooth. The orthodontic correction function of the device is active under occlusal loads generated during mastication.

  • Publication number: 20160278884
    Abstract: An orthognathic correction device includes a first retainer, a second retainer and at least two elastic members. The first retainer is configured to be removably worn on the maxillary dental arch of a patient and has at least two first connection parts fixed on the left and right buccal surfaces of the first retainer. The second retainer is configured to be removably worn on the mandibular dental arch of the patient and has at least two second connection parts fixed on the left and right buccal surfaces of the second retainer. The elastic members couple the first and second retainers worn and retained on the maxillary and mandibular dental arches of the patient, respectively, so as to drive the second retainer to move relative to the first retainer, thereby adjusting the relative position between the mandible and the maxilla of the patient.
