The material for forming translucent wear resistant dental enamel having an opacity less than 50 percent, a localized wear volume loss of less than 0.025 mm3 and a localised extended wear volume loss of less than 0.04 mm3, comprises a polymerizable matrix forming liquid and inorganic filler particles. The liquid comprises polymerizable material having a first refractive index. The filler comprises a first plurality of particles having a second refractive index. The first plurality of particles being formed from a low (0.1 to 1.0 micrometers) and a high (1 to 10 micrometers) median particle size plurality of particles. The first refractive index being within 5 percent of said second refractive index. Preferably the filler further comprises a second plurality of filler particles having an average particle size of from about 0.01 to about 0.04 micrometers.

L'invention porte sur un matériau constitutif d'émail dentaire translucide et résistant à l'usure présentant une opacité inférieure à 50 %, une perte de volume par usure localisée de moins de 0,025 mm3 et une perte de volume par usure étendue de moins de 0,04 mm3, et consistant en un liquide formant une matrice polymérisable et une charge de particules non organiques, ledit liquide présentant un premier indice de réfraction, et la charge comprenant un premier ensemble de particules présentant un deuxième indice de réfraction. Ce premier ensemble contient un premier groupe de particules d'une taille moyenne comprise entre 0,1 et 1,0 mu m, et un deuxième groupe de particules d'une taille moyenne comprise entre 1 et 10 mu m, le premier indice de réfraction étant de moins de 5 % du deuxième. La charge comporte de préférence un deuxième ensemble de particules d'une taille moyenne comprise entre environ 0,01 et 0,04 mu m.
