  • Patent number: 5647743
    Abstract: A device for the orthopedic treatment of jaw fractures or tooth displacements has ring-shaped dental bands which surround the teeth and are detachably secured to at least two teeth of a jaw. In order to attach the dental band to the tooth in a secure and detachable manner, at least two tensioning blocks are integrally shaped on the dental band. The tensioning blocks are arranged in pairs at a distance from each other, aligned bores and/or threaded holes are created in both tensioning blocks and the gap may be reduced by means of at least one tensioning screw held in the bores or threaded holes.
