A series of preformed teeth aligners or positioners, worn in succession and changed every few weeks, designed to influence the shape and/or function of the stomatognathic system; often used to impact a patient's appearance and self image. It is typically custom-made using computer-generated modelling based on an initial oral impression, and a consultation with an orthodontist. It is typically made of a clear hard plastic, e.g., a thermoformed polycarbonate (PC). It is typically used to correct malocclusions such as underbites, overbites, cross bites and open bites, or crooked teeth and various other flaws of teeth and jaws, whether cosmetic or structural. This is a single-use device.
A custom-made orthodontic appliance, typically supplied in series intended to be worn in succession and self-changed every few weeks, designed to influence the shape and/or function of the stomatognathic system to correct malocclusions (e.g., underbites, overbites, cross bites, open bites, crooked teeth) and/or other cosmetic and/or structural flaws of teeth and/or jaws. Also described as sequential or successive, the device is custom-made based on an oral impression, self-removable, and is typically made of clear/transparent synthetic polymers (e.g., a thermoformed polycarbonate); a post-treatment orthodontic retainer/positioner may be included with the device. This is a reusable device.
