SYSTEM NH is a non-precious dental cast alloy for crowns and bridges on nickel-base, type 4
SYSTEM NH is easy to use and quick to polish with excellent laser welding properties. The alloy can be melted by open flame or induction heating.
SYSTEM NH can be used with any commercial, phosphate-bonded investment material (our recommendation: ADENTA®-VEST CB).
SYSTEM NH can be veneered with any high-fusing ceramics.
