A mill blank assembly for making a dental prosthesis includes a milling section and a support section. The support section is adapted to fit in a chuck or collet of a milling machine. One of the milling section and the support section includes a projection that extends into a recess of the other, in order to enhance the strength of the bond between the milling section and the support section. As a result, the completed assembly is less likely to fracture or become disassembled during the milling process.
La présente invention concerne un ensemble ébauche pour fraisage dentaire destiné à la fabrication d'une prothèse dentaire qui comprend une partie fraisage et une partie support. La partie support est adaptée de façon à s'ajuster dans le mandrin ou dans la pince-barre d'une fraiseuse. L'une des deux parties de cet ensemble comprend une projection qui se prolonge dans un évidement de l'autre partie, de manière à renforcer la liaison entre la partie fraisage et la partie support. Cet ensemble complet est ainsi moins susceptible de se fracturer ou de se désassembler durant le processus de fraisage.
