Abstract
The variations of temperature of simply modified dental-casting-full-crowns at solidification time were simulated by the finite-element-method.The solidifying process of chromium-nickel alloy was different from that of gold-palladium-silver system alloy.The temperature of castings in chromium-nickel alloy was differed with the location.This phenomena was caused by low thermal conductivity of alloy at solidification time.Castings of gold-palladium-silver system alloy had a homogeneous temperature at solidification time.In the case of thin castings of chromium-nickel alloy, the difference of locational temperature were selectively increased.Simulation of solidification-process by the finite-element-method was a suitable technique for dental casting.The results of simulation allowed prediction of the location and form of crack and shrinkage hole in castings.
