You cannot autoclave zirconia: MYTH
Autoclaving. This is one of the funniest myths we’ve heard lately.
There is actually a company selling zirconia pediatric dental restorations saying that you cannot autoclave zirconia. They are telling dentists that it can change color? Yikes, back up the trolley!
Which is false, they are 100% autoclavable. Zirconia can withstand incredibly high temperatures without affecting the structural integrity, shade or finish.
A little education on the processing of zirconia. After milling (or injection molding for that matter), zirconia has to be sintered which shrinks it and hardens it to the durable material it becomes. The sintering process is done at a temperature from 1200 – 1600°C. Our glazing process bring the material once again up to over 900°C. How in the world is anyone supposed to believe that putting zirconia in an autoclave at 100°C could alter any characteristics of the zirconia material?
Again, a bizarre, and definitely misleading statemen
