Description
Giesskanal für einen zahnraedizinischen AbformlöffelPouring channel for a dental impression tray
Beschreibung:Description:
Stand der Technik sind Abforralöffel für die Zahnmedizin in die Platzhalter in Form von Schnüren u.ä.eingelegt werden.Mit diesen Schnüren wird ein Vorabdruck vorgenommen.Dann werden die Schnüre entfernt und der entstandene Hohlraum Zahn für Zahn mittels eines speziellen Instrumentes freigeschnitten.Danach wird der Abform löffel wieder in der Patientenmund eingebracht und durch einen vorhandenen Kanal von Außen dünnflüssiges Silikon eingespritzt. Das Freischneiden bedeutet einen erheblichen Arbeitsaufwand und die Form einer einfachen Schnur erschwert den Silikon fluß. Sinn d'er Erfindung ist es daher einen der Form des verwendeten Abformlöffels angepassten Kanal zu bieten.Dieser Kanal muß so gestaltet sein,daß er in dem Löffel präzise und dennoch leicht zu fixieren ist,er muß im Löffel deutlich hochstehen,damit die Zähne des Patienten bei der Vorabdrucknahme bis auf den Kanal durch beißen können - dies führt dazu,daß später nicht mehr freige schnitten werden muß,er muß die Einsprizöffnung präzise ver schließen und die Möglichkeit bieten ohne unnötigen Kraftaufwand aus dem Vorabdruckmaterial herausgezogen werden zu können. Hierzu ist die Ausführung einer Griffschleife vorgesehen.Um das Herausziehen ebenfalls zu erleichtern ist vorgesehen die Form zum Einspritzkanaleingang hin konisch verdickend zu halten was außerdem den Fluß des später eingebrachten dünnflüssigen Silikons begünstigt.The state of the art is impression trays for dentistry into which placeholders in the form of cords etc. are inserted. A preliminary impression is made using these cords. The cords are then removed and the resulting cavity is cut free tooth by tooth using a special instrument. The impression tray is then placed back in the patient's mouth and thin liquid silicone is injected from the outside through an existing channel. Cutting free means a considerable amount of work and the shape of a simple cord makes the silicone flow difficult. The purpose of the invention is therefore to provide a channel that is adapted to the shape of the impression tray used. This channel must be designed in such a way that it can be fixed precisely and yet easily in the tray. It must stand up clearly in the tray so that the patient's teeth can bite through to the channel when the preliminary impression is taken - this means that it no longer has to be cut free later. It must close the injection opening precisely and offer the possibility of being able to be pulled out of the preliminary impression material without unnecessary effort. A handle loop is provided for this purpose. To make pulling out easier, the shape is designed to be conically thickened towards the injection channel entrance, which also promotes the flow of the thin liquid silicone that is later introduced.
