Disclosed is a polymerizable composition for dental applications, which is suitable as an implant temporary cement and a mobile tooth fixing material. The polymerizable composition for dental applications comprises: an alkyl styrene block copolymer (a) that comprises a polymer block (A) mainly composed of a styrene unit having a C1-8 alkyl group and a polymer block (B) mainly composed of at least one monomer unit selected from the group consisting of a conjugated diene compound unit, a unit produced by adding hydrogen to a conjugated diene compound unit, and an isobutylene unit； a polymerizable monomer (b)； and a polymerization initiator (c).
