A dental model includes a quantity of mold material having portions that represent oral structure, as well as a holder in contact with the mold material. The holder has a textured surface for secure connection with the mold material, and preferably is embedded in the mold material as the mold material is hardened. The dental model is especially suitable for use with computer-aided milling systems, since the holder provides for convenient releasable connection to a fixture during the time that a scanner or other device collects data representing the oral structures of interest.
L'invention se rapporte à un modèle dentaire comportant une certaine quantité de matériau de moulage possédant des parties qui représentent une structure orale, ainsi qu'un support en contact avec le matériau de moulage. Ledit support possède une surface texturée permettant un assemblage avec le matériau de moulage, et il est de préférence intégré au matériau de moulage lorsque celui-ci durcit. Ce modèle dentaire est particulièrement adapté aux systèmes de fraisage assistés par ordinateur du fait que le support permet un assemblage facile et libérable avec un dispositif de fixation au cours de la collecte, par un scanner ou autre dispositif, des données représentant les structures orales d'intérêt.
