The present invention relates generally to systems, devices, and methods for tracking compliance of orthodontic appliance usage, and more specifically to systems, devices, and methods for tracking compliance of orthodontic appliance usage using a compliance device and/or a light therapy apparatus. The invention provides compliances device that can be configured to be disposed within a patient's mouth. In some embodiments, the compliance device can comprise a sensor configured to detect an input associated with whether an orthodontic appliance is at least partially disposed within the patient's mouth at a first time and at a second time, with the second time being subsequent to the first time.

Polymeric shell appliances are provided in which the polymeric shell appliances are configured to provide one or more activation forces to facilitate tooth movement. In many embodiments, the activation forces are arranged to provide force in a direction opposite to an intended direction of tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.

A lip advancer is presented for preventing proclining or tipping forward of the lower incisors that causes relapse and gingival recession in retention with forward intermaxillary elastic traction that extends diagonally from posterior bracket hooks in the lower arch anchored to hooks on upper anchorage appliances. In one embodiment, the lip advancer is comprised of an invisible clear liner type plastic retainer for use with a dental arch, and a bumper extending labially from the retainer for pressing against the patient's lip causing the lip muscles to react pushing back with an opposite force thus preventing the anterior teeth from flaring labially. In another embodiment, for use with a plurality of brackets and an archwire, the lip advancer comprises an auxiliary archwire extending from and in contact with the brackets, and a bumper formed on the auxiliary archwire for applying pressure labially to a corresponding lip.
