A new casting method for titanium revealed that the mechanical properties of pure titanium castings were close to those of gold alloy and more ductile than Ni-Cr or Co-Cr alloy. In this investigation, more than a hundred pure titanium crowns were produced and tested clinically.The fitness of titanium crowns was slightly inferior to silver-palladium low gold crowns but superior to nickel-chromium crowns. Only one case each of discoloration and occlusal wear of titaoium crowos have been observed in the mouth during a two-year period. The degree of adhesion of plaque to cwnors was about the same among silver-palladium low gold, nickel-chromium and pure titanium.
