All NuSmile ZR Try-In crowns are precisely manufactured to be identical in size and shape to NuSmile ZR crowns and can be reused and autoclaved for try-in purposes. If contamination of the inner surface of the NuSmile ZR crown occurs, one of two processes is recommended to best retain the cement on the crown.
