Zusammenfassung
Der Engstand im Unterkiefer des Wechselgebisses kann in 80 % der Fälle mit dem Erhalt und der Nutzung des Leeway-Spaces beseitigt werden, während bei einem Oberkiefer-Engstand häufig eine Zahnbogenerweiterung durchgeführt werden muss.
Dieser Artikel schildert und diskutiert wenig bekannte Therapieansätze, die das Ziel haben, den Engstand zu beheben, ohne die bleibenden Zähne in einer festsitzenden Apparatur einzubeziehen.
Abstract
In the mixed dentition, crowding in the lower arch can be solved in 80 % of the patients by preserving and utilizing the Leeway space, while in the upper arch, expansion is frequently requested in order to gain adequate space.
This article shows and discusses some uncommon early treatment procedures in order to solve the crowding in the mixed dentition without touching permanent teeth.
