title: Crown and bridge disassembly--when, why and how.
abstract: Crown and bridgework has a finite life span and fails for a number of reasons. Removal is often by destructive means. There are a number of clinical circumstances, however, in which a conservative disassembly would aid the practitioner in completing restorative/endodontic procedures. The aims of this paper are to provide a classification for crown and bridge removal systems; describe how a number of such systems work; and when and why they might be considered.
  
  
  CONCLUSIONS
  Crown and bridge removal is a frequent occurrence for dentists. There are many situations in which salvaging extracoronal restorations may be more helpful than their destruction.
