ABSTRACT:
Dental clasps are removable secured to teeth in part by wire ears engaging the natural undercut of the teeth and in part by engagement with buttons adhered to the teeth. Clasps are modified for the above purpose and also form combinations to engage different areas of teeth to correct various occlusions. Preferably the clasps are encased in molded plastic appliances which fit a single arch or a portion thereof or fit both arches. The plastic appliance preferably does not cover the occlusal surfaces; hence the patient's mouth may close to a more normal position. The buttons are shaped to facilitate installation of the appliance, as by tapering the outside surface of the button or the slot in the button which receives the clasp.
