Patent number: 8083521Abstract: 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 has 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. The second anchor has an outer head portion for attachment to an orthodontic appliance and is attached to the first anchor. The second anchor also may have an inner threaded portion in engagement with the cortical bone. 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.Type: GrantFiled: April 30, 2008Date of Patent: December 27, 2011Assignee: Toads LLCInventors: David Baughman, Jack Fisher

Patent number: 7806686Abstract: An apparatus and method for anchoring orthodontic appliances or the like in the mouth wherein anchor screws of different constructions are installed in the bone in different areas of the mouth to insure adequate bone contact and retention. Each of the anchor screws has a threaded portion and a washer portion at the outer end of the threaded portion which is of sufficient width to engage the adjacent exterior bone surface when the threaded portion is installed in the bone to provide lateral support for the threaded portion. In some cases, the threaded portion is provided with threads of different sizes and the washer portion is provided with an exterior thread for cutting through gum tissue to enable the washer portion to engage the underlying adjacent exterior bone surface when the threaded portion is installed in the bone. Each anchor screw is provided with a lateral bore at the outer end thereof for receiving a ligature or the like therethrough to prevent the anchor screw from falling in the mouth.Type: GrantFiled: August 24, 2006Date of Patent: October 5, 2010Assignee: Toads LLCInventors: David Baughman, Jack Fisher
