To create a general awareness among the clinicians regarding the appropriate choice of crown removal systems and techniques in various clinical situations. Fixed prosthodontic treatment is often faced with complications involving failure of restoration or of the abutment due to improper treatment planning. In such situations, further management can be accomplished either by removal and replacement or repair of the restoration. Removal of the crown and bridges for refabrication is extremely tedious and can lead to unpredictable consequences if proper technique is not used. An external device is always required for the removal of the failed restorations. Decrowning devices are a boon to dentistry to deal with such situations. Numerous decrowning devices are available commercially. This review describes and demonstrates the various available devices based on the mode of action. Literature search was carried out using PubMed and Google Scholar from 1970's to till date. Any decrowning device will be successful only if used appropriately. Hence, this literature attempts to suggest the possible application of each system based on clinical situations. A few modified techniques have also been discussed in this article for ease of the clinician.
