SYSTEM KN is a non-precious dental cast alloy for crowns and bridges on nickel-base, type 3
SYSTEM KN 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 KN can be used with any commercial, phosphate-bonded investment material (our recommendation: ADENTA®-VEST CB).
SYSTEM KN can be veneered with any high-fusing ceramics.
