A succession of dental appliances may be used to provide airway remodeling. The airway remodeling may provide for treatment of snoring or sleep disordered breathing. The dental appliances may have an outside wall, an inside wall, and a channel to receive a dental arch between the inside wall and the outside wall. The inside wall may extend so as to apply pressure to a bone structure, when worn by a user. The succession of dental appliances may have successively greater arch widths and/or lengths.

The present disclosure provides a dental orthodontic appliance and a design method and a manufacturing method thereof. The dental orthodontic appliance includes a shell-like body, and the shell-like body is provided with a plurality of cavities for accommodating maxillary teeth, and the shell-like body is further provided with an upper palatal arch that reshapes a form of a dental arch. Two ends of the upper palatal arch are respectively and partially connected to positions of gingival margins or positions adjacent to the gingival margins on ligual sides in posterior regions of left and right sides of the shell-like body. When the shell-like body interacts with teeth, the upper palatal arch can induce buccolingual lateral amplification of maxillary palatal suture bone deposition by means of deformation, and teeth in the posterior regions move laterally buccolingually under an action of the shell-like body.

Provided is an exchangeable or replaceable maxillary skeletal expander. The exchangeable maxillary skeletal expander including: a pair of guides configured to be fixed by micro implants implanted into maxilla; and an expansion part including: a pair of main bodies configured to be inserted and extended while sliding between the pair of guides; and an expansion screw configured to penetrate the pair of main bodies and adjust an interval between the pair of main bodies.

An orthodontic appliance may include an outer shell having a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance may also include an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.

Described herein is an oral appliance. The oral appliance includes upper and lower trays that each include at least one axial spring configured to contact a palatal/lingual surface of at least one tooth, where each axial spring is coupled to the respective upper or lower tray, and where each axial spring is configured to produce and transmit intermittent, cyclic forces to the palatal/lingual surface of the tooth to promote palatal and upper/lower jaw development. The upper and lower trays each include an expansion mechanism to enable adjustment of the size of the upper and lower trays to account for palatal expansion and upper and lower jaw development. The oral appliance includes first and second adjustable hinge arms that are removably connected to the upper and lower trays so that the oral appliance advances the mandible to provide temporary relief from sleep disordered breathing, sleep apnea and/or snoring.
