The left and right bodies are made of different materials. In particular, the left body is formed of a metal material having a high thermal conductivity and the right body is formed of a plastic material having a low thermal conductivity.

Therefore, when the resin is injected into the flask, the resin of the left body made of a metal having a high thermal conductivity is rapidly polymerized, and the resin of the right body made of a plastic having a low thermal conductivity is polymerized at a slow speed.

Therefore, when the resin is injected into the flask, the resin of the left body made of a metal having a high thermal conductivity rapidly becomes hardened, and the resin of the right body made of a plastic having a low thermal conductivity hardens at a slow speed. Therefore, when the resin is made of the same material but the dental prosthesis made from the metal mold of the left body is rapidly thermally polymerized, polymerization shrinkage and deformation are caused. In the denture made of the plastic body of the right body, So that it can be minimized. The metal of the flask of the left body is mainly made of aluminum. The plastic of the right side body is mainly made of BMC material.

The tooth part of the dental prosthesis is located inside the right plastic body flask and the gingival part where the tooth is fixed is located inside the metal body flask of the left body. Therefore, there is a remarkable effect of minimizing the deformation of the dental prosthesis molded by using a denture molding flask made of different materials, particularly, minimizing the deformation of the gingival region and facilitating the wearing thereof.
