Abstract

The dowel pin is for use in dentistry, being fixed in the plaster by a sleeve, both being tapered and half-round. The pin can have a recess at one end, engaging with a boss inside the sleeve, also an insertion point securing it in the impression. There can be bosses on the outside of the sleeve to secure it in the plaster. A recess at the end can secure an arch pin cap, so that if the point cannot be inserted in the impression it can be held by a flexible needle.

Description

ModellstiftModel pen

1.) Pätentbeschreibung Der Modellstift, auch Dowel - Pin genannt, dient dazu einzelne Zähne, Zahnstümpfe oder Kieferteile aus dem Modell zu entfernen und wieder genau im Modell zu fixieren.1.) Description of the patent The model pen, also called Dowel pin, is used to remove individual teeth, tooth stumps or jaw parts from the model and to fix it again exactly in the model.

Bisherige Modellstifte hatten auf Grund ihrer Konstruktion und Materialbeschaffenheit folgende Nachteile: Sehr hohes Gewicht und Herstellungskosten, da aus Metall. Modellstift und Hülse sind Farallelwandig, daher schwergängi- schon beim Einsetzen in die Hülse, geringe Haftmöglichkeit der Hülse im Gips, daher Ungenauigkeiten bei der Fixierung. Keine Verwendungsmöglichkeit bei Stiftzähnen.Previous model pens had due to their construction and material properties the following disadvantages: Very high weight and manufacturing costs, since they are made of metal. Model pen and sleeve are parallel-walled, therefore stiff - even when inserting into the sleeve, Possibility of adhesion of the sleeve in the plaster of paris, therefore inaccuracies in the fixation. Cannot be used with pin teeth.

Der von mir entwickelte Modellstift mit Hülse besteht aus Kunststoff und hat zur Fixierung im Abdruck eine Spitze, die ein Umkippen beim Ausgießen verhindert. Da die Spitze auch aus Xststoff besteht, kann sie je nach 'wunsch leicht mit den Fingern gekürzt werden. Der Modellstift und die Hülse sind konisch, daher leicht ineinandersteckbar. Ein Verdrehen des llodellstiftes in der Hülse wird durch den halbkreisförmigen Querschnitt beider Teile verhindert. Umein Herausfallen des Modellstiftes aus der Hülse zu verhindern, ist am Ende des Modellstiftes eine Vertiefung vorgesehen, die in eine Erhebung in der Hülse einrastet.The model pen with sleeve developed by me is made of plastic and has a tip for fixation in the impression, which prevents it from tipping over when pouring. Since the tip is also made of fabric, it can easily be attached to the Fingers are shortened. The model pin and the sleeve are conical, therefore light nestable. A twisting of the llodellstiftes in the sleeve is by the semicircular cross-section of both parts prevented. To prevent the model pen from falling out To prevent it from getting out of the sleeve, a recess is provided at the end of the model pen, which engages in an elevation in the sleeve.

Damit die Hülse gegen Zugkräfte im Gips gesichert ist, sind am oberen, äußeren Rand der Hülse schmale Wülste aufgetragen. Für die Herstellung eines Stumpfes bei Stiftzähnen dient die Hülse als Modellstift, der beim Ausgießen des Abdruckes über den Stift im Abdruck gestülpt wird. Die beiden Wülste dienen wieder als Fixierung. Am Ende der Hülse befindet sich wie bei dem Modellstift auch eine Vertiefung, die in eine Erhebung in einer Bogen - Pin - Kappe einrasten kann. Diese wird dann verwendet, wenn die Spitze am Modellstift sich nicht in die Abdruckmasse eindrücken läßt.So that the sleeve is secured against tensile forces in the plaster of paris, outer edge of the sleeve applied narrow beads. For the production of a stump In the case of pin teeth, the sleeve serves as a model pin, which is used when the impression is poured is placed over the pin in the impression. The two bulges serve as a fixation again. As with the model pen, there is also a recess at the end of the sleeve that can snap into a bump in an arch pin cap. This is then used if the tip of the model pen cannot be pressed into the impression material.

Modellstift 2.) Patentbeschreibung Die Bogen - Pin - lappe ist am Ende mit einer biegsamen Nadel ver-bunden, die in die hbdrukkmasse gesteckt wrd, um beim Ausgießen des Abdruckes den Modellstift zu fixieren.Model pin 2.) Patent description The arch pin - flap is on The end is connected to a flexible needle that is inserted into the pressure mass, to fix the model pen when pouring the impression.

Die Kappe ist so geformt, daß sie einerseits über die Hülse und aberauch über den Modellstift geschoben werden kann und einrastet. Der Modell stift besteht also aus drei Teilen, die auch einzeln gebraucht werden können, dem Modellstift mit oteckvorrichtung, der Hülse und der Bogen - Pin- Kappe.The cap is shaped so that it on the one hand over the sleeve and on the other hand can be pushed over the model pen and clicks into place. The model pen is made in other words, from three parts that can also be used individually, the model pen with oteckvorrichtung, the sleeve and the bow-pin cap.
