Abstract

L'invention a pour but de fournir un kit d'enrobage dentaire qui permet l'ajustement avec une couleur préférée et une application sécurisée dans un court laps de temps, qui peut améliorer le brillant des plans dentaires, sans pour autant augmenter la surface d'une dent. L'objectif est atteint en produisant un kit d'enrobage dentaire constitué d'un boîtier (I) rempli d'une composition d'enrobage (I) constituée (a1) d'un composé éthyléniquement insaturé, (b1) d'un initiateur de polymérisation et (c1) d'un remplisseur et d'un boîtier (II) rempli d'une composition d'enrobage (II) constituée (a2) d'un composé éthyléniquement insaturé et, si nécessaire, (b2) d'un initiateur de polymérisation et (c2) d'un remplisseur, caractérisé par le fait que le contenu (wt%) du remplisseur (c2) de la composition (II), [(c2)/[(a2) + (b2) + (c2)] × 100, est inférieur au contenu (wt%) du remplisseur (c1) de la composition (I), [(c1)/[(a1) + (b1) + (c1)] x 100.
