Document Type and Number:
Japanese Patent JP5833568
Kind Code:
B2
Abstract:
A method of dispensing a hardenable dental composition, which can form a temporary bond, comprising 1) providing multi-part hardenable dental composition comprising part (A) in the form of a paste comprising acid-reactive glass particles and a liquid selected from the group consisting of water, a monomer having at least one ethylenically unsaturated group per monomer molecule, and a combination thereof; and part (B) comprising a water soluble polyacid and a liquid selected from the group consisting of water, a monomer having at least one ethylenically unsaturated group per monomer molecule, and a combination thereof; wherein an adhesion reducing component is included in part (A); part (B); or parts (A) and (B); water is included in part (A); part (B); or parts (A) and (B); the monomer having at least one ethylenically unsaturated group per monomer molecule is included in part (A); part (B); or parts (A) and (B); and at least one component for initiating polymerization of the monomer is included in part (A); part (B); or parts (A) and (B); and 2) extruding the composition through a static mixer in fluid communication with a first reservoir containing the part (A) and a second reservoir containing the part (B); wherein a plunger is positioned in each reservoir for simultaneously forcing part (A) and part (B) into the static mixer, extruding the composition through the static mixer, and dispensing the composition; and wherein an extrusion force of less than 40 pound-force (178 newtons) according to Test Method I is applied to the plunger for extruding the composition through the static mixer without the aid of a mechanical advantage provided by an attached or external device; a method of bonding a prosthetic device to a dental structure using the dispensing method, a device for dispensing the composition using the dispensing method, a kit comprising the device, and the composition used in the dispensing method are provided.
