Zusammenfassung

Elongierte obere Molaren müssen vor einer prothetischen Rehabilitation der Unterkiefer-Molarenregion in vielen Fällen zunächst intrudiert werden. Dies stellt jedoch eine große Herausforderung an die Verankerung dar. In diesem Artikel wird die Verwendung der „Mini-Mausefalle“ beschrieben, die sich auf (Mini-) Implantaten im anterioren Gaumen abstützt. Um die Apparatur klein und effizient zu gestalten, kann die Intrusionsmechanik auch ohne einen Transpalatinalbogen eingesetzt werden. Bei nicht optimal ausgerichteter Kraftwirkungslinie kann es jedoch ohne TPA zu Kippungen der zu intrudierenden Zähne kommen.

Abstract

In many cases, elongated upper molars must be intruded prior to prosthetic rehabilitation of the mandibular molar region. However, this poses a great challenge for the anchorage. This article describes the use of the “mini mousetrap”, which rests on (mini) implants in the anterior palate. In order to make the appliance small and efficient, the intrusion mechanism can also be used without a transpalatal arch. If the line of force is not optimally aligned, however, the teeth to be intruded may tilt without TPA.
