title: Technique for removing cement between a fixed prosthesis and its substructure.
abstract: Failed restorations diagnosed with salvageable and subsequently reusable metal substructures that demand their separation can be clinically challenging to undertake without the risk of damaging either the super- or substructures. This article describes a technique to safely separate them from each other in order for the respective substructure to be reused in the fabrication of a newly reconstructed restoration and for the existing restoration to be reused as a provisional where appropriately indicated.
