PROBLEM TO BE SOLVED: To provide a one-step type cement composition for temporary adhesion suitable for implant temporary adhesion cement, excellent in all of discharging properties and forming properties of a composition, adhesion with metal and ceramics, and flexibility and damping properties of a cured product without requiring a primer.SOLUTION: A one-step type dental cement composition for temporary adhesion includes: a styrene block copolymer (a) including a polymer block A principally comprising styrene units and a polymer block B principally comprising at least one type of monomer unit selected from an isoprene unit and a hydrogenated isoprene unit, where the total amount of 1,2-bond units and 3,4-bond units in the polymer block B is ≥40 mol%; a (meth)acrylate polymerizable monomer (b); and a polymerization initiator (c). A content of the styrene block copolymer (a) is 2.5-100 pts.wt. relative to 100 pts.wt. of the (meth)acrylate polymerizable monomer (b). |
