major role in the fabrication and temporary cementation of a provisional crown

essential that a provisional crown or bridge remain cemented while the fixed
prosthesis is being prepared and delivered to the dental office. When the
patient returns for final cementation of a fixed crown or bridge, the

just in case it will need to be recemented if the final prostheses needs to be
sent back to the lab for adjustments and remake.
