Orthodontic appliance and method of use

An orthodontic appliance comprises a combination of pre-made and custom elements to provide treatment versatility with minimized costs and time delays. The appliance comprises a pre-made arch member segment elastically deformed to removably attach to coupling units bonded to teeth. The appliance also comprises a connection module to further elastically deform the arch member segment to generate motive forces or to just connect separate arch member segments in variations. In another embodiment the appliance comprises pre-made connectors having one end attached to a tooth and another end elastically deformed to attach to an arch component. The attachment to teeth comprises coupling units bonded to teeth in variations. The arch components, coupling units, and connection modules may be custom made to match surfaces inside the mouth. Motive forces may be generated by the elastic deformation of the arch member segment, connectors, arch component, or connection module to align teeth.
