Die Komposit-Injektionstechnik zur Erzielung eines ästhetischen Ergebnisses nach kieferorthopädischer Behandlung
The composite injection technique to achieve an esthetic result after orthodontic treatment
Zusammenfassung
Hintergrund Dieser Artikel stellt eine konservierende Methode für die Umgestaltung von Frontzähnen nach kieferorthopädischer Behandlung vor. So können beispielsweise Zapfenzähne, Nichtanlagen und Diastemata trotz kieferorthopädischer Behandlung zu ästhetisch und funktionell nachteiligen Ergebnissen führen. Neben prothetischen und chirurgischen Lösungsansätzen rücken durch verbesserte Materialeigenschaften vermehrt auch Kompositaufbauten in den Mittelpunkt der Therapie.
Klinischer Fall Die klinische Situation einer Patientin nach kieferorthopädisch erfolgtem Lückenschluss aufgrund von Nichtanlage der lateralen Inzisiven wurde mittels Abdrucks und Modellscanner in eine Software überführt, um ein digitales Mockup zu erstellen. Auf Grundlage dieses Modells wurde anschließend ein durchsichtiger Silikonschlüssel fabriziert, der nach entsprechender Vorbereitung der Zähne intraoral positioniert und über Injektionskanäle mit einem fließfähigen Komposit befüllt wurde.
Schlussfolgerung Für die mittelfristige und minimalinvasive Versorgung von Frontzähnen eignet sich die Komposit-Injektionstechnik grundsätzlich sehr gut. Dabei ermöglicht das Vorgehen auch bei komplexen Frontzahnaufbauten ästhetisch gute und reproduzierbare Ergebnisse.
Abstract
Background This article presents a conservative procedure for the modelling of anterior teeth after orthodontic treatment. For example, pivot teeth, agenesis of teeth and diastemata can lead to aesthetically and functionally unsatisfactory results despite orthodontic treatment. In addition to prosthetic and surgical solutions, composite build-ups are increasingly becoming the focus of therapy due to improved material properties.
Clinical case The clinical situation of a patient after orthodontic space closure due to agenesis of the lateral incisors was transferred to software using an impression and modelscanner to create a digital mock-up. Based on this mock-up, a translucent silicone key was subsequently fabricated, which, after appropriate preparation of the teeth, was positioned intraorally and filled with a flowable composite via injection channels.
Conclusion The direct composite injection technique is very suitable for the medium-term and minimally invasive restoration of anterior teeth. The procedure allows aesthetically good and reproducible results even for complex anterior reconstructions.
