Zusammenfassung
Im vorliegenden Fallbericht wird die Therapie einer Angle Klasse-II / Subdivision mit maxillärer Mittellinienverschiebung zur Klasse-I-Seite beschrieben. Durch kontrollierten reziproken Lückenschluss konnte eine Klasse-I-Okklusion auf der Extraktionsseite und kongruente Mittellinien eingestellt werden. Der Lückenschluss erfolgte mit einer Klasse-I- bzw. Klasse-II-Gummizug-Gleitmechanik. Durch Verwendung einer „Low-friction“-Apparatur konnte auf eine skelettale Verankerung verzichtet werden.
Abstract
This case report describes the treatment of an Angle class II / subdivision with maxillary midline shift to the class I side. By controlled reciprocal space closure a class I relationship on the extraction side and matching midlines could be established. The extraction space closure was performed with class I and class II elastics respectively. By using a “low friction” appliance skeletal anchorage could be avoided.
