(EN) METHOD AND DEVICE FOR PRODUCING A DENTAL COMPONENT
(FR) PROCÉDÉ ET DISPOSITIF UTILISABLES EN VUE DE LA FABRICATION D'UN COMPOSANT DENTAIRE
Abstract
(EN)
The present invention relates to a method and device for producing a dental component. The method comprises: a) providing a piece of material (10) attached to or held by a first holding means (12); b) shaping the piece of material to form the dental component (16) and at least one support pin (18) maintaining the dental component attached to the first holding means or the initial piece of material; c) engaging a second holding means (24) to the dental component while the dental component still is attached to the first holding means or the initial piece of material via the at least one support pin; and d) removing the at least one support pin from the dental component while the dental component is engaged by the second holding means.

(FR)
La présente invention concerne un procédé et un dispositif utilisables en vue de la fabrication d'un composant dentaire. Ledit procédé comprend les étapes consistant a) à utiliser un fragment d'un matériau (10) fixé à un premier moyen de retenue (12) ou maintenu par celui-ci ; b) à façonner ledit fragment de matériau pour lui donner la forme du composant dentaire (16) et d'au moins une tige de support (18) maintenant le composant dentaire fixé au premier moyen de retenue ou au fragment initial de matériau ; c) à solidariser un second moyen de retenue (24) avec le composant dentaire alors que ce dernier est toujours fixé au premier moyen de retenue ou au fragment initial de matériau par l'intermédiaire de ladite ou desdites tiges de support ; et d) à éliminer ladite ou lesdites tiges de support du composant dentaire tandis que ce dernier est toujours solidaire du second moyen de retenue.
