The purpose of this study was to observe the thermal expansion of the inlay waxes at temperature. Inlay pattern wax shows not only a high coefficient of expansion but also a tendency to warp or distort when allowed to stand unrestrained. The thermal expansion of inlay waxes was tested according to the treatment conditions for 10 minutes at 40'C. The thermal expansion of inlay waxes at various temperatures was measured with an electro dial gauge. The results were as fellows: 1. It is shown that the rate of thermal expansion of wax A is 0.2%, wax B is 0.29%, wax C is 0.38%, and wax D is 0.22% at 40'C. 2. It is shown that the coefficient of thermal expansion of wax A is 106*10-6/'C , wax B is , wax C is 152*10-6/'C , and wax D is s116*10-6/'C at 40'C. 3. The thermal expansion of the inlay waxes at 40'C was shown to increase in the order of wax C, B, D, A.
