Abstract
Metal and/or partial metal dentures having a surface modified by a pulsed electron beam system. The system includes an explosive emission cathode, an accelerating gap formed by the cathode and plasma anode, and an electron collector where the metal and/or partial metal dentures are fixed, and placed into a magnetic field. The surface of the modified metal and/or partial metal denture has high reflectance like a mirror polished surface and high corrosion resistance.
Claims5
Metal and/or partial metal dentures adapted to be inserted into a human mouth and provide an appearance of teeth, the dentures comprising:
- an at least partially metal substrate providing the form of the teeth and having at least one polished, amorphous surface obtained by application of pulsed electron beam irradiation,
- said substrate being made of an Ag—Pd—Au alloy.
