An orthodontic appliance comprising a resilient member arranged to be positioned between the upper and lower arches and force-generating elements applying forces to at least some of the teeth of at least one of the arches. The resilient member is made over an orthodontic setup or a model having ideal arch form and includes sockets for the occlusal surfaces of the teeth of each of the arches arranged such that when the teeth seat in the sockets, they will be in the ideal or best possible occluding positions relative to each other. Any suitable type of force-generating means may be used to apply traction to one or more of the teeth of one of the arches toward the teeth of the other of the arches.
