Title (EN) PREFORM FOR THE PRODUCTION OF A DENTAL PROSTHESIS
(FR) PRÉFORME DESTINÉE À LA FABRICATION D'UNE PROTHÈSE DENTAIRE
Abstract:
(EN) The invention relates to a porous preform for the production of a dental prosthesis, said preform comprising a group of agglomerated ceramic, glass-ceramic or glass particles, such that (expressed as volume percent): more than 40% and less than 90% of the particles of the aforementioned group have a size greater than 0.5 µm and less than 3.5 µm, said particles being hereafter referred to as “enamel particles”; and more than 10% and less than 60% of the particles of the group have a size greater than 3.5 µm and less than 5.5 µm, said particles being hereafter referred to as “dentin particles”, the Ve/(Ve+Vd) ratio of the volume percent Ve of enamel particles to the volume percent Vd of dentin particles changing continuously along an axis X, known as the “axis of variation”.
(FR) L'invention concerne une préforme poreuse destinée à la fabrication d'une prothèse dentaire, ladite préforme comportant un ensemble de particules agglomérées, en matière céramique, en matière vitrocéramique ou en verre, tel que, en pourcentages volumiques : - plus de 40% et moins de 90% des particules dudit ensemble présentent une taille supérieure à 0,5 µm et inférieure à 3,5 µm, lesdites particules étant désignées ci- après « particules d'émail », et - plus de 10% et moins de 60% des particules dudit ensemble présentent une taille supérieure à 3,5 µm et inférieure à 5,5 µm, lesdites particules étant désignées ci- après « particules de dentine », le rapport Ve/(Ve+Vd) du pourcentage volumique Ve en particules d'émail sur le pourcentage volumique Ve en particules de dentine évoluant de manière continue suivant un axe X, dit « axe de variation ».
