Abstract: The present invention relates to a device for orthodontic and/or orosurgical purposes, the device comprising an elongated, dimensionally stable, self-supporting profiled element, some sections of which are curved and approximate to the vestibular side of a dental arch, the profiled element being held by at least one front fixing element that can be anchored in the bone and is allocatable as a rule to the interforaminal region of the submaxilla or to the anterior mandible, and the profiled element forming at least one anchorage point, upon which a retaining member is acting, for a segmental distraction or a bone-supported orthodontic tooth displacement.

Abstract: Apparatus for the expansion of the palate with an extension part which may be lengthened and/or shortened it its length, which has on each of its two ends a fixation part the improvement wherein each fixation part (7, 18, 30) is constructed in the form of a single-point bone connection.
