Description
Die Erfindung betrifft ein Verfahren zur Herstellung orthodontischer Bögen nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for producing orthodontic sheets according to the preamble of
Zur Regulierung von Zahnfehlstellungen werden im Allgemeinen orthodontische Bögen mit Hilfe von Verbindungselementen (sog. Brackets) an den Zähnen eines Patienten befestigt. Diese Brackets weisen hierzu eine Aufnahme (Slot) für den orthodontischen Bogen auf. Die Slots weisen jeweils drei Wände auf, welche den Bogen im montierten Zustand umgeben. Die bekannten Slots stellen also ein offenes System dar, so dass der Bogen zur Öffnungsseite des Slots hin keine oder nur eine höchst unvollständige Kraftübertragung zur Korrektur einer Zahnfehlstellung bewirken kann.Orthodontic arches are generally fastened to the teeth of a patient by means of connecting elements (so-called brackets) for the regulation of tooth misalignments. These brackets have for this purpose a receptacle (slot) for the orthodontic arch. The slots each have three walls which surround the arch in the mounted state. Thus, the known slots represent an open system, so that the arc to the opening side of the slot can cause no or only a very incomplete power transmission for correcting a tooth misalignment.
Ein weiterer Nachteil konventioneller orthodontischer Bögen ist deren Herstellung aus einem Drahtbogen, wie sie beispielsweise in der
In der
Die
Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art anzugeben, das die Herstellung orthodontischer Bögen mit einer verbesserten Kraftübertragung ermöglicht.The object of the invention is therefore to provide a method of the type mentioned, which allows the production of orthodontic arches with improved power transmission.
Es ist regelmäßig vorgesehen, dass die Verbindungselemente (Brackets) zwei bevorzugt etwa senkrecht zueinander stehende Ausnehmungen aufweisen. Die Vorrichtung erlaubt so den Einsatz zweier orthodontischer Bögen, wobei der Einsatz eines zweiten Bogens in die zweite Aufnahme in diesem Fall die Nachteile bei der Verwendung von Verbindungselementen mit nur einer Aufnahme minimiert bzw. kompensiert. Dies geschieht dadurch, dass die Öffnungen der Aufnahmen in unterschiedliche Richtungen weisen. Jede der Aufnahmen bildet für sich ein offenes System, jedoch wird die aufgrund der Öffnung einer Aufnahme in eine Richtung unzureichende Kraftübertragung durch einen in der jeweils anderen Aufnahme positionierten Bogen kompensiert.It is regularly provided that the connecting elements (brackets) have two preferably approximately mutually perpendicular recesses. The device thus permits the use of two orthodontic arches, wherein the use of a second arch in the second receptacle in this case minimizes or compensates for the disadvantages of using fasteners with only one receptacle. This happens because the openings of the recordings have different directions. Each of the receptacles forms an open system per se, however, the insufficient due to the opening of a recording in one direction power transmission is compensated by a positioned in the other recording sheet.
Erfindungsgemäß sind die verwendeten Bögen durch Rapid-Prototyping, selektives Laser-Schmelzen oder Laser-Mikrostrukturierung hergestellt.According to the invention, the sheets used are produced by rapid prototyping, selective laser melting or laser microstructuring.

Die Herstellung der Vorrichtung erfolgt erfindungsgemäß in der nachfolgend geschilderten Weise:
Mit Hilfe einer Abformung wird ein Gipsmodell eines Patientenkiefers erstellt, der eine Zahnfehlstellung aufweist. Das Modell wird dupliziert und der Zahnkranz des Duplikatmodells wird in Einzelzahnsegmente getrennt, die in der therapeutisch geplanten Position orientiert werden. Dieses Idealmodell wird durch einen 3D-Scanner in einen Datensatz für die Weiterverarbeitung am Computer überführt. Möglich ist auch das direkte intraorale Scannen des Patientenkiefers und die virtuelle Umstellung der Einzelzahnsegmente in die Soll-Position.The device is produced according to the invention in the following manner:
With the help of an impression, a plaster model of a patient's jaw is created, which has a tooth misalignment. The model is duplicated and the sprocket of the duplicate model is separated into single-tooth segments oriented in the therapeutically planned position. This ideal model is transferred by a 3D scanner into a data set for further processing on the computer. Also possible is the direct intraoral scanning of the patient's jaw and the virtual conversion of the single tooth segments into the desired position.
Am Computer wird dann eine zweidimensionale Konstruktionsebene festgelegt, die die ideale Ausrichtung der Verbindungselemente

Das Intervall zwischen Anfangsposition und Zielposition der Einzelzähne kann in Einzelschritte differenziert werden, so dass sich jeweils einzelnen Behandlungsschritten entsprechende Bogenverläufe ergeben. Durch die Herstellung dieser Bögen ist es möglich, einzelne Behandlungsschritte durchzuführen. Dabei muss berücksichtigt werden, dass die auf den Einzelzahn einwirkende Kraft durch die Materialeigenschaften und den Querschnitt des Bogens
