摘要：
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.
