<P>PROBLEM TO BE SOLVED: To provide a nozzle for extruding a dental composition which improves preservation stability of a dental composition by separating a catalytic agent for polymerizing a monomer of the dental composition such as liquid or paste-like dental resin cement containing at least a monomer, a dental autopolymer resin, or resin-reinforced dental glass ionomer cement from the liquid or paste-like dental composition, reduces the number to divide the dental composition, and is mounted on one end of an extruding device for extruding the dental composition for hardening the extruded dental composition. <P>SOLUTION: The catalytic agent for polymerizing the monomer in the extruded dental composition is adhered in an extruding path of the nozzle for extruding the dental composition mounted on one end of the extruding device for extruding the liquid or paste-like dental composition containing at least the monomer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
