A Novel Treatment for Propagated Crown Fractures

A major complication after endodontic treatment is persistent pain on biting or chewing. Although unsuccessful endodontic treatment can account for such pain, pain to chewing and biting can also be a result of an unsupported or propagated crown fracture. Crown fractures that extend apically result in deterioration of the localized periodontium and ultimate loss of the tooth. To date, no predictable treatment for apically extending crown fractures exists.


Three cases of nonsurgical excision of a propagated crown fracture and the repair of the subsequent iatrogenic perforation are presented.


This case report series describes a novel treatment for apically progressive crown fractures that results in patient comfort and maintenance as well as improved periodontal status of the tooth.
