Functional and Esthetic Rehabilitation Using Anatomic Post and All-Ceramic Crown: A Case Report

Restoration of endodontically treated anterior teeth with flared root canals presents both functional and esthetic challenges due to the loss of substantial coronal and radicular dentin. This case report describes the esthetic and structural rehabilitation of a severely compromised maxillary anterior tooth using a customized anatomic fiber post and a lithium disilicate ceramic crown. An anatomic post was fabricated by relining a prefabricated fiber post with composite resin directly within the root canal to achieve optimal adaptation and stress distribution. The coronal portion was restored using an adhesively bonded lithium disilicate crown to achieve high esthetic integration and strength. This conservative approach successfully restored the form, function, and esthetics of the tooth while preserving remaining tooth structure. The case highlights the clinical advantages of using anatomic posts and modern adhesive restorative materials in managing flared canals with minimally invasive techniques.
