during adaptation of Stainless steel crown, many times 2 or 3 crowns are checked for fit and finally one is selected and adapted and cemented. these unselected one are blood stained and infectious. Do you reuse such crowns following your method of decontamination and sterilization
how do you decontaminate these and sterilize it?
Do you have any study in this subject.
Dear Dr.
That was a very important question that needed to be raised. Try crows I use are made by 3M and they are very good in the physical properties. I do re use after decontamination first with hydrogen peroxide, followed by cleaning and Autoclave sterilization.
may be this article is useful to you.

hope you find it useful. I also recommend a study impression just to reduce the number of try in if possible.

Dont know why , no SS crown manufacturer recommends reuse or gives any instruction in this regard. can there be any reason other than commercial interest
I see no Problem in reusing SSCs after try in - after desinfection and sterilizing. Actually, we treat this crowns as any other used steel-Instrument (probes, burs etc.).
We reuse only that crowns, which were not adapted (modified with crampon or shortened).
Perhaps it would be interesting, if any properties of the SSC are modified by try-in or sterilization... But would it led to clinical consequences - other then the recommendation of "safe" reuse?
YOU CAN RE USE AFTER Decontamination and sterlization. When we can modify the size by adding or reduce a size by welding , why can't we reuse after try in once sterilisation is done
If no manipulation or trimming was performed, then you can but after getting it autoclaved.
We can reuse the unselected SSC after the try-in but have to disinfect with Na hypochloride and then sterilize in an autoclave. Although blood or saliva may have contaminated it during the trial period, disinfecting and autoclave could suffice.
What maybe unethical is to reuse a SSC previously fitted on a px tooth for a period of time, now removed and place on another px, even if one have disinfected and autoclaved the crown
