wie solcher bei Anwendung der Metallegierungen in Pulver- bezw. Feilspäneform entsteht, erspart. Mit einem Satze Pillen in verschiedenen Grössen, wie der in der Zeichnung darge-
EMI2.2
gamierung die Zahnhöhlung auszufüllen vermag, da infolge der Dichtigkeit der Pillen eine Volumenveränderung beim Amalgamieren dos Materiales kaum eintritt.
Ausserdem wurde die Beobachtung gemacht, dass durch den Druck von ungefähr 5 Atmosphären, welchem das Metallpulver bezw. die Metallspäne bei Herstellung der Pillen oder Tabletten unter. worfen werden, die Metallegierung auch derart physikalisch günstig beeinflusst wird, dass bei ihrem Verarbeiten zu Amalgam weniger Quecksilber verwendet worden muss und dadurch die Volumenbeständigkeit des Amalgams erhöht wird.
Nicht unerwähnt bleibe, dass allerdings schon Kupforamalgamtabletten zu zahnärzt- lichen Zwecken in den Handel kommen. Diese Tabletten stellen aber ein wirkliches Amalgam dar, bei welchem das Metall (Kupfer) an Quecksilber gebunden ist, so dass sie nur verwendet worden können, wenn durch Erhitzen der Kupforamalgamtabtetton, das Quecksitbot wieder frei gemacht worden ist, während die Pillen bezw. Tabletten nach vorliegender Erfindung kein Quecksilber enthalten und einfach Presslinge der Pulverförmigen bezw, feilspäneförmigen Metallogierung darstollon, die durch geringen Druck oder durch Zerreibung wieder zerfallen, sobald der Zahnarzt eine Mischung mit Quecksilber vornehmen will.
Auch sind zur Herstellung von Zahnbrücken bestimmte Metallegierungen in Würfel- oder Kugel-

Nr. 9069/98 bekannt. Es sind dies aber gegossene, leicht schmelzbare Würfel oder Kugeln, die bei ihrem Gebrauch geschmolzen werden : diese sind nicht mechanisch zorreibbar und daher auch nicht zur raschen Bildung eines Amalgams für Zahnfüllungen geeignet wie dio

schlag kam jedoch in der Praxis nicht zur Ausführung (Vide z. B. Lehrbuch dor zahn- tochnischon Metallarboit von August Polscher, herausgegeben bei Georg Maske in Oppenheim, im Jahre 1896, Seite 74) einmal weil die Vergoldung dünner Motailblättcbon viel zu umständlich ist und dann, weil eine Legierung in Blättchenform zur Amalgambildung nicht so geeignet ist, wie die Legierungen in Pulver-bezw. Feilspiineform.

such as when using the metal alloys in powder or. File chip form is created, saved. With a set of pills of different sizes like the one shown in the drawing
EMI2.2
Gamierung is able to fill the tooth cavity, since due to the tightness of the pills there is hardly any change in volume when the material is amalgamated.
In addition, it was observed that the pressure of about 5 atmospheres, which the metal powder resp. taking the metal filings when making the pills or tablets. are thrown, the metal alloy is also physically favorably influenced in such a way that less mercury has to be used when processing it into amalgam, thereby increasing the volume stability of the amalgam.
It should not go unmentioned that copper amalgam tablets for dental purposes are already on the market. These tablets, however, represent a real amalgam, in which the metal (copper) is bound to mercury, so that they can only be used if the mercury has been cleared again by heating the cupola amalgam tray, while the pills respectively. Tablets according to the present invention contain no mercury and simply compacts of the powdery or filet-shaped metallography that disintegrate again when the dentist wants to mix it with mercury when the dentist tries to mix them with mercury.
For the production of dental bridges, certain metal alloys are also available in cubes or spheres
EMI2.3
No. 9069/98 known. However, these are cast, easily meltable cubes or spheres that are melted when they are used: these cannot be mechanically rubbed and are therefore not suitable for the rapid formation of an amalgam for dental fillings like dio
EMI2.4
Schlag was not implemented in practice (vide e.g. textbook dor Zahntchnischon Metallarboit by August Polscher, published by Georg Maske in Oppenheim, in 1896, page 74) because the gilding of thin Motail leaves is much too laborious and then, because an alloy in flake form is not as suitable for amalgam formation as the alloys in powder or. Filing spine shape.
