ORTHODONTIC AND ORTHOPAEDIC JAWBONE ANCHOR

摘要

Orthodontistry, and the manipulation of jaw growth, conventionally make use of apparatus fixed on anchor teeth. These teeth may move undesirably or may be absent, and alternatives include osteointegrated anchors such as that of EP-A-0818183 and anchors screwed into the bone such as that of WO-A9612451. Such anchors when placed in the palate necessitate a connection with teeth before the orthodontic/orthopaedic appliances can apply forces, and when fixed in the upper jaw make treatment difficult in the lower jaw. These disadvantages are circumvented by the present invention, whereby forces are applied via a horizontal connection piece (4) and a retentive part for elastic bands (5) on metal plates (1) fixed in the outer cortex of the jawbone, directly on the jawbone.
