Abstract: The present invention relates to a deagglomerated glass filler for sustained ion release for imparting ion sustained-release property to a dental material for use in the dental field. The dental material means a material for use in filling, prosthetic repair, temporary sealing, temporary bonding, preparation of a prosthetic appliance, adhesion/luting, pit and fissure sealing, or the like in a dental treatment. A glass filler for sustained ion release that sufficiently continuously releases a metal ion present in a glass composition as compared with a conventional glass filler for sustained ion release has been demanded in the field of a dental material. Such an object is achieved by a glass filler for sustained ion release that is obtained by performing a silane compound treatment step and an acidic polymer treatment step and that is controlled to satisfy a specific D50 particle size relationship in each of the steps.

Abstract: An applicator that is less expensive than those according to the related art and in which a plunger does not easily slip out of a cylindrical syringe. A cylindrical syringe and a plunger are each molded from a resin material. A resistance structure is provided between the inner peripheral surface of the cylindrical syringe and the outer peripheral surface of a pressing portion of the plunger. The resistance structure is configured to act as resistance to movement of the pressing portion when the pressing portion is moved toward a cartridge fitting portion beyond a predetermined position and to movement of the pressing portion when the pressing portion is moved from the side of the cartridge fitting portion toward an end of the cylindrical syringe opposite to the cartridge fitting portion beyond the predetermined position.

Abstract: A paste-type dental material is filled from an opening portion of a cartridge into a cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge along a kneading surface, on which the paste-type dental material is kneaded, with the opening portion being inclined. The piston is placed on the kneading surface with a circular end surface of the piston contacting the kneading surface. The piston is inserted into the cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge closer to the piston located on the kneading surface such that a piston-side tapered surface or the piston-side curved surface of the piston is fitted into the opening portion, and thereafter moving the one of the two ends of the cylindrical portion toward the kneading surface.

Abstract: A dental mill blank having a multi-layer structure has been required to improve the reproducibility of a color tone of the natural tooth in a dental crown restoration cut by CAD/CAM technique. Especially, a reproduction of the color tone of a cavity or a groove is required in a dental crown form of the molar tooth. The present dental mill blank has three or more layers wherein a color of a 30% position layer which includes a 30% position which is a position spaced from a surface of the dental mill blank of a W layer-side by 30% satisfies a specified relational expression, and a contrast ratio of the 30% position layer is within a range of the contrast ratio of the D layer×(0.70 to 1.00).
