Description

Evakuierungssystem für zahnärztliche Abformungen Beschreibung:Dental impression evacuation system Description:

Stand der Technik sind zahnärztliche Abformungen bei denen mit einem speziell geformten Abdrucklöffel mittels eines bei der ersten Vorabformung in das Bodenteil der Abformung eingelegten Platzhalters ein Hohlraum geschaffen wird,der zum Vorderteil des Löffels aus dem Patientenmund herausragt. Nach Entfernung des Platzhalters und Rückpositionierung des Löffels in den Patientenmund wird von Vorne- vor dem Munde des Patienten das dünnfließende Korrekturmaterial mittels einer Spritze unter Druck in den hohlen Kanal eingebracht. Dieses Verfahren führt dazu,daß Blut,Speichel und andere feine Verunreinigungen vom Korrekturmaterial weggespült werden. Bei ungünstigen Verhältnissen kann es aber zu Luftstau oder Blasenbildung kommen.The state of the art is dental impressions in which a cavity is created with a specially shaped impression tray using a placeholder placed in the base of the impression during the first preliminary impression, which protrudes from the front of the tray out of the patient's mouth. After removing the placeholder and repositioning the tray in the patient's mouth, the thin-flowing correction material is introduced into the hollow channel from the front of the patient's mouth using a syringe under pressure. This process means that blood, saliva and other fine impurities are washed away from the correction material. However, under unfavorable conditions, air can build up or bubbles can form.

Sinn der Erfindung ist es daher vor der Korrekturabformung mit dem dünnfließenden Material in der Abformung ein Vakuum zu erzeugen ,welches dann Verunreinigungen aus den abzuformenden Bereichen entfernt,bevor die Korrekturabformung erfolgt. Hierzu wird während der Vorabformung ein Schlauch in die beiden hinteren Abschlüsse der Abfromungen eingelegt - oder nachträglich mittels einem geeigneten Instrument in das ausgehärtete Silikon eingeschnitten.Danach wird der hohle Schlauch in beide Enden eingelegt und außerhalb des Patientenmundes mittels eine T Stückes miteinander verbunden.The purpose of the invention is therefore to create a vacuum in the impression before the corrective impression is taken using the thin-flowing material, which then removes impurities from the areas to be molded before the corrective impression is taken. To do this, a tube is inserted into the two rear ends of the impression during the preliminary impression - or subsequently cut into the hardened silicone using a suitable instrument. The hollow tube is then inserted into both ends and connected to each other outside the patient's mouth using a T-piece.

Hieran wird dann entweder eine großvolumige Spritze oder eine kleine Vakuumpumpe angeschlossen.Either a large-volume syringe or a small vacuum pump is then connected to this.

Die Abformung kommt zur Korrekturabformung zurück in den Patientenmund.der abzuformende Bereich wird evakuiert.Hierbei spürt der Patient wnn der Unterdruck aufgebaut ist.Erst danach erfolgt die Korrekturabformung mit dem dünnfließenden Silikon welches nun durch das Vakuum noch besser fließt und feiner zeichnet.The impression is returned to the patient's mouth for correction. The area to be molded is evacuated. The patient feels when the negative pressure has built up. Only then is the corrective impression taken with the thin-flowing silicone, which now flows even better and draws more finely thanks to the vacuum.
