Hello everybody, This is me again, I will post two photos, both crows should be A3,5, They are CubeX2, The theet 1.1 was sintered at 1450 C. The theet 2.1 was sintered at 1500 C. Both crowns looks too grey and with a pearly appearance, such as the colour having inside a marine oyster. The sintering same sintering curves for both crowns, the only difference was the high Temp (1450C and 1500C):
Ramp 1: 8° C per minute
High Temp 1: 900° C
Hold: 0 hr 30 min
Ramp 2: 3° C per minute
High Temp 2: 1550° C
Hold: 2 hr 0 min
Cooling Reg: Cool to 400° C in 2 hours and then let cool to room temperature naturally.
Both crowns, have grey effect Dental Direkt liquids in the incistal portion, A4+ in the cervical portion, SA2 in the incisal portion and dipping in A4 for about 1 minute. I let dry for about 2 hours at room temperature.
(Furnace and Heatting elements MoSi2 are brand new)
How can achieve better results? What I need to change?
Thank you very much, regards
