Dental Press Ingots
Lithium disilicate dental press ingots are ideal for making monolithic single-crown, veneer restorations.
Press ingots features simple, fast crystallization process and present naturally aesthetics result. It comes to HT(high translucency) and LT(low translucency), and vital 16 colors, plus blench shade(BL1,BL2,BL3,BL4)
Lithium disilicate dental press ingots indications: thin veneer, veneer, inlay, onlay, partial crown, anterior crown, poster crown.
Press ingots feature
- Naturally aesthetic restoration effect,
- High chemical composition stability and bonding strength,
- Simple and easy milling, fast crystallization procedure.
