<p>PROBLEM TO BE SOLVED: To enable the stable use of a model for plastic molding of a base of a dental model at the time of forming dentures by providing the mold with a base plate having a mold cavity of a jaw shape provided with hole arrays in a base part and positioning and arranging the set of plugs having pin arrays to be inserted into these hole arrays in the mold cavity. SOLUTION: The base plate 1 is provided with the mold cavity having the shape of the jaw delineated from the bottom 2 and inner and outer side walls 3 having spirals or tooth-shaped materials along the edge of the base plate 1. Leg parts 4 are integrally formed on the outside surface of the side wall 3 on the outer side. The bottom 2 is provided with two rows of the holes 6 along the edge of the base plate 1. These holes 6 are formed at regular intervals in such a manner that a specified total is attained at the time the interval of the two adjacent holes of the first hole array is added to the interval of the two adjacent holes of the second hole array. A belt-like body having the plugs 7 connected to a ribbon form is housed into the mold cavity and, at this time, the belt-like body is positioned and fixed by inserting a pin array disposed in the lower part of the plugs into the array of the holes 6.</p> |
