<p>A bow assembly comprises a face bow (12) with an outer bow (5) and an inner bow (1), and two attaching means (2) for connecting the ends (3) of the inner bow with tooth-elements (4), in particular the molars of the upper jaw. Said attaching means each include a tube (7) attachable on a tooth-element (4) in which an end (3) of the inner bow can be slided. Each tube (7) is attachable on a tooth-element in a position substantially parallel to the longitudinal axis of the tooth-element and the ends of the inner bow extend substantially perpendicular to the main plane of the inner bow. The ends (3) of the inner bow (1) each are freely rotable with respect to the corresponding tube (7) when the ends of the inner bow are slided into the corresponding tubes.</p> |
