An orthodontic appliance and associated systems and methods are disclosed herein. In some embodiments, the appliance comprises an anchor configured to be positioned adjacent a patient's teeth, and an arm extending away from and coupled to the anchor. The arm can include a first end portion at the anchor and a second end portion configured to be coupled to a securing member adhered to a tooth of the patient. The second end portion can include a first region and a second region extending from the first region at an angle. When the appliance is positioned adjacent the patient's teeth and secured to the securing member, the first and second regions may inhibit the second end portion from translating and/or rotating relative to the securing member.

Systems, methods, and devices for producing orthodontic appliances are provided. In one aspect, an orthodontic appliance comprises an outer shell comprising 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 can comprise 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.

A mandibular positioning facial retrognathism orthodontic system and a design method thereof are disclosed. The orthodontic system includes a maxillary shell-like dental appliance having a shell-like body, a protrusion portion protruding toward an opposite jaw is disposed at a posterior area corresponding to the shell-like body, a traction portion is disposed at a labial side of the shell-like body, and a retaining portion configured for fastening with a retaining attachment is disposed at the posterior area corresponding to the shell-like body. The protrusion portion is engaged with the posterior area of a mandibular for occlusal reconstruction, so that mandibular incisors are aligned with maxillary incisors. The design method is a design method for the mandibular positioning facial retrognathism orthodontic system, which can provide a treatment-specific orthodontic system, thereby achieving treatment of mandibular positioning facial retrognathism.
