Purpose: This article describes an original solution for a tooth with an existing cast post
and core placed subgingivally. Materials and Methods: The tooth was erupted rapidly
using a simplified and easy technique that incorporates fiberotomy during the process of
movement. Results: The distal finish line of the core, which was subgingival before
movement onset, was elevated, allowing the placement of crown margins on sound tooth
structure. Clinical evaluation of the tooth after a period of 4 weeks, during which a
provisional acrylic resin crown was used for retention, showed no need for corrective
surgery, and fabrication of a metal-ceramic crown (Captek) was begun. Conclusion:
When failing to place crown margins on sound tooth structure, the existence of a cast
post and core in such a nonrestorable tooth may serve as an anchor in the process of
rapid extrusion. Following the need to respect the biologic width and fulfill the obligatory
ferrule effect circumferentially, this extrusive treatment modality was applied to meet high
treatment standards. Int J Prosthodont 2003;16:225–228.
