There is disclosed herein an appliance for orthodonture characterized in that at least most of the appliance may be manually installed and removed by the patient, as required. This appliance includes a plurality of individual clasps for gripping onto individual upper or lower teeth of the patient. The clasps are configured such that they can be manually placed in gripping positions onto and manually disengaged from the teeth by the patient. At the same time, first and second continuous arch wires are connected at predetermined points along their lengths to the various clasps such that when the clasps are in gripping positions on their respective teeth, the wires extend from tooth to tooth along the facial and lingual sides of the teeth, respectively, and exert forces on the teeth to move the latter from malocclusion positions to desired, more ideal positions.
