Zusammenfassung

Die Knochenmorphologie jedes Menschen weist einzigartige Strukturen auf. Deshalb lassen sich Mini-Platten, wie beispielsweise die Mentoplate, nur in stark vereinfachter Form konfektioniert herstellen. Konfektionierte Platten benötigen deshalb eine zeitaufwendige intraoperative Anpassung, um annähernd den knöchernen Strukturen zu entsprechen. Durch Intraoralscans und dreidimensionale Bildgebung lässt sich die anatomische Situation so präzise wiedergeben, dass im CAD/CAM-Verfahren individualisierte Mini-Platten und kieferorthopädische Apparaturen hergestellt werden können. Dies reduziert Risiken und Komplikationen, die mit der Insertion einer Mini-Platte einhergehen können. Da die Mini-Platten zudem mithilfe einer Einsetzhilfe (Insertions-Guide) eingesetzt werden, ermöglicht dies eine präzise Umsetzung geplanter Zahnbewegungen und verringert die Operationsdauer bei der Insertion deutlich. Der vorliegende Artikel beschreibt mögliche digitale Herstellungsverfahren zur Anfertigung individuell gedruckter Mini-Platten und der auf diesen verankerten kieferorthopädischen Apparaturen.

Abstract

Due to the uniqueness of every human’s bone structure, preformed mini-plates can only be manufactured in a simple form.

Mini-plates require a time-consuming intraoperative adjustment to fit the specific bone structures appropriatly. Using intraoral scans and three-dimensional reconstruction, the anatomical situation can be reproduced with sufficient precision to manufacture individualized mini-plates and orthodontic appliances in the CAD/CAM process. This reduces risks and complications that are associated with the insertion of mini-plates. Since these mini-plates can also be installed using an insertion guide, the precise implementation of planned tooth movements can be assured and the surgical time can be reduced. This article describes possible digital manufacturing processes for producing individual printed mini-plates and the orthodontic appliances anchored on them.
