Abstract
This study obtained the following consequences, as a result of the comparative analysis for thecastability depending on an angle of the sprue and wax pattern in case of manufacturing dentalprostheses, for the castability depending on direction, and for the castablility of sprue, whichattached the reserve to each different 3.5mm roll wax(sprue wax) and to 2.5mm sprue wax. 1. As a result of the comparative analysis for the castability depending on an angle of the sprueand wax pattern, the best castability was shown when the angle of the sprue and wax pattern is180°?(straight line), and the lowest castability was shown in 45°?, which was curved most, andthere was no statistical significance. 2. As a result of the comparative analysis for the castability of an angle depending on direction,the best castability was shown in the farthest side from the direction of centrifugal casting, and thelowest castability was shown in the same side as the direction of centrifugal casting, and therewas no statistical significance. 3. Given comparing the castability depending on the pattern of sprue, the better castability wasshown in 135°?and 180°?when using 3.5mm roll wax(sprue wax), compared to attaching thereserve to 2.5mm sprue wax.
