Disclosed is a fixing pin for a model teeth die connecting a model teeth die to a model base. The fixing pin includes a model base inserting portion having a side expansion portion and being inserted into the model base, and a die inserting portion being fixedly inserted into the model teeth die. The model base inserting portion is a taper type, and the side expansion portion is a streamline and expands from one side of the model base inserting portion. Further, the die inserting portion is formed on the upper surface of the model base inserting portion neighboring to the side expansion portion. Thereby, when the model teeth die is connected to the model base, it is prevented from being rotated. Further, the fixing pin may be easily manufactured.
