ANCHOR APPARATUS FOR ORTHODONTIC APPLIANCES

摘要

Anchor apparatus for orthodontic appliances for moving a molar or the like. A first anchor is attached to the cortical bone adjacent to one side of the molar. The first anchor is elongated and comprises an outer head portion for attachment to an orthodontic appliance, and an inner threaded portion in engagement with the cortical bone. A second anchor is disposed on the side of the molar opposite to the one side. In one embodiment, the second anchor comprises an outer head portion for attachment to an orthodontic appliance and is attached to the first anchor. In a second embodiment, the second anchor also comprises an inner threaded portion in engagement with the cortical bone. The inner threaded portion of the second anchor may be threadably or slidably received within the inner threaded portion of the first anchor. The first and second anchors are substantially longitudinally aligned with each other to minimize the space taken up by the anchors adjacent to the molar.
