[QUOTE="DentalTechTips, post: 219184, member: 16131"] Conversely... Milling e.max takes MUCH less time and labour than Zr... A traditional Full Zirconia crown will take 15 minutes to scan and design, 15 minutes to mill, any green state contouring/colouring could take another 30 minutes and an 8-12 hour sintering cycle. Final polishing/fitting: 5 minutes, staining and glazing 15 minutes. So Zr is anywhere between 9.5-13.5 hours to finish... (keep in mind that this figure compounds based on the amount of units going into the sintering furnace) Milled e.max takes 15 minutes to scan and design, 15 minutes to mill, 15 minutes blue stage contouring/fitting, 30 minutes crystallization, and I prefer to do an extra characterization bake with some cut back which adds another 30 minutes. So e.max is 1.25 to 1.75 hours to finish. (crystallization also compounds this figure downwards with more units per cycle) [/QUOTE]
