<p>PROBLEM TO BE SOLVED: To provide a dental wax material restoring an abutment tooth gypsum work model and improving measurement accuracy of a marginal line based on a laser beam in manufacture of a crown prothesis by means of a CAD/CAM system. SOLUTION: A dental wax material consists of a white wax 5 changed into an abutment tooth gypsum working model 1 so as to be built up and a black wax 6. The white wax is charged or built up in a gypsum chipped part formed because of foam, breakage or the like so as to be matched with the shape of an abutment tooth inside the mouth. Because the white wax reflects a laser beam, the abutment tooth gypsum working model provides measurement information equal to that about the abutment tooth inside the mouth. The black wax is applied to the marginal line M outside. Because the black wax absorbs a laser beam, the marginal line as an application boundary is clarified.</p> |
