  • Patent number: 6575741
    Abstract: The present invention provides an intra-oral anchorage which comprises a flexible belt that extends around and between the teeth of a patient. The belt has locking means fixed thereon to receive a free end portion of the belt and lock said portion against retraction therefrom. The locking means is in the form of a buckle. The intra-oral anchorage of the present invention can be used to hold a jaw in a fixed position, in the case of a broken jaw for example. It offers ease of application and therefore a reduction in the cost of surgery as well as eliminating the risk of “needle stick” injury inherent with cutting and bending multiple ends of wire. It causes less gum damage in placement and removal, which is similarly easier, faster and less uncomfortable for the patient.
