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: Provided is a two-component mixing container in which a piston member may be capable of a rotation motion operation and a linear motion operation without the need for a complex guide groove. Two or more spring structure portions are provided at the piston member. The two or more spring structure portions impart a pressing force on an inner wall surface of the third cylindrical portion. Two or more fitting grooves are formed in the third cylindrical portion. In this fitting state, the piston member and a second-component containing member rotate together without contact portions getting out of the fitting grooves. When a force of a predetermined level or higher toward a third bottom wall portion is applied to an operating rod portion with a second-component containing chamber and a mixing chamber being communicable with each other, the contact portions get out of the fitting grooves.
