Abstract
Description
Beschreibung :Description :
Stand der Technik sind zahnmedizinische Abformlöffel die als Halteelement zur Aufnahme von Abformmaterial dienen. Das Angeknetete Abformmaterial wird in seiner noch plastischen Phase in den Abformlöffel gegeben und dem Patienten in den Mund eingesetzt.Das Material härtet in Minuten aus, kann aus dem Mund entnommen werden und stellt das Negativ für die zahntechnische Modellherstellung dar.State of the art dental impression trays are used as a holding element for impression material. The kneaded impression material is placed in the impression tray while it is still plastic and placed in the patient's mouth. The material hardens in minutes, can be removed from the mouth and represents the negative for the dental model production.
Es gibt auch Abformlöffel mit denen beide Kiefer gleichzeitig abgeformt werden können. Damit das eingebrachte Abformmaterial nicht abfließt ist in der Mitte des Löffels ein Gazestreifen oder andere verkreuzte Strukturen - ähnlich wie Stoof einge bracht. Diese zwischen den abzuformenden Zahnreihen sitzende Stoffstärke führt allerdings zu Störungen der Abformung da das Material sich durchdrückt und ein gänzliches Zusammenbeissen der Zähne verhindert.There are also impression trays that can be used to take an impression of both jaws at the same time. To prevent the impression material from running off, a strip of gauze or other crossed structures - similar to fabric - is inserted in the middle of the tray. However, this thickness of material, which sits between the rows of teeth to be molded, leads to problems with the impression because the material pushes through and prevents the teeth from biting together completely.
Desweiteren besitzen diese Löffel wenig Stabilität und auch keine Haltemöglichkeiten für Abformmaterialien.Furthermore, these trays have little stability and no holding options for impression materials.
Erfindungsgemäß wird daher ein neuartig konstruierter Abform löffel zu gleichzeitigen Abformung von Ober - und Unterkiefer vorgeschlagen der zum Halt des Abformmaterials keinen kompletten Gazestreifen besitzt sonder nur ganz dünne Querverbindungen in der Mitte des Löffels - etwa in der Höhe der songenannten Okklusionsflache. Da die Zahnreihen auch bei maximalem Kontakt immer kleine Freiflächen zwischen Ober - und Unterkiefer haben können die dünnen Querverbindungen bei der Abformung in diese Hohlräume ausweichen und so einen exakten Biss erlauben. Die Konstruktion eines solchen Löffels in einem Guss erhöht dessen Stabilität. Retentionen zum besseren Halt des Abform materials können beliebig eingebracht werden.According to the invention, a newly designed impression tray is proposed for simultaneous impressions of the upper and lower jaws, which does not have a complete gauze strip to hold the impression material, but only very thin cross-connections in the middle of the tray - approximately at the height of the so-called occlusal surface. Since the rows of teeth always have small open spaces between the upper and lower jaws, even with maximum contact, the thin cross-connections can move into these cavities during the impression, thus allowing an exact bite. The construction of such a tray in one cast increases its stability. Retentions for better hold of the impression material can be inserted as desired.
Läßt man mindestens eine Öffnung in der Wandung des Löffels, so kann man vor der Abformung einen Platzhalter einlegen, diesen später herausziehen und als "Gußkanal" für die später einge brachte Korrekturmasse nutzen.If you leave at least one opening in the wall of the tray, you can insert a placeholder before taking the impression, pull it out later and use it as a "casting channel" for the correction material that will be added later.
Dieser Platzhalter kann einseitig oder Ober - und Unterkiefer gleichzeitig versorgen.This space maintainer can serve one side or the upper and lower jaw simultaneously.
Ebenso kann der Löffel selbst nur einen Rahmen darstellen und ein der Form des Löffels angepasster Einsatz die Funktion des Haltelementes für das Abformmaterial erfüllen.Likewise, the tray itself can only represent a frame and an insert adapted to the shape of the tray can fulfil the function of the holding element for the impression material.
