Summary
[edit]DescriptionBertoni 3-way-expander.jpg |
English: The special triple screw element („Bertoni screw“) in this upper removable brace allows to expand in width, to shape the front and to uncrowd the eye teeth at the same time, due to the T-shaped subdivision of the rigid yellow body. For untwisting the incisors, the rim that pushes them from the inside against the outer wire has been levelled to an even shape.
Deutsch: Diese herausnehmbare Oberkiefer-Spange enthält eine 3-Wege-Schraube („Bertonischraube“) in einer T-förmigen Unterteilung des Plastiks. Dadurch kann zugleich quer gedehnt und die Frontzähne vorgeschoben werden, wobei auch mehr Platz für beengte Exkzähne entsteht. Weiterhin wurde der Vorderrand glattgeschliffen, um von innen kommend verdrehte Schneidezähne gegen den äußeren Federdraht richtig zu drehen. |
