PURPOSE: To provide a dental mechanic model reproduction flask which is simple and of favorable operability in which hardening expansion of an embedded material is compensated. CONSTITUTION: A foil insert F of a thickness S corresponding to the size of an embedded member is put in a zone of a parted surface T of two mating dies 1, 2, a model to be reproduced (of a tooth root, for example) is put to penetrate the foil insert F roughly at a center of the whole length L and favorably in a range of a flask center axial line M to be held at a specified position. After the foil insert F is taken out, a flask K is further closed for the quantity of hardening expansion, thereby the hardening expansion is compensated.
