Aim: Fiber-post and direct composite resin application in root canal treated teeth with high substance loss are one of the preferred methods in conservative dentistry. In this case, a large old restoration with discoloration and fractures in the maxillary central incisor was detected. The purpose of this case report is to present the restoration of the old filled central incisor with fiber post and composite resin application.
Materials and Methods: In the oral examination of a 27-year-old male patient, it was determined that tooth 11 had a large and old composite restoration and that the natural tooth structure was lost as far as the cervical line. No lesions were found in the root tip and surrounding tissues in the radiographs taken. Adequate isolation was provided with cotton roll suctions in the patient, and the old restoration was removed and the stage of insertion of the fiber post was initiated. Suitable space was created in the canal in such a way that the apical 1/3 was left to the gutta-percha. After the radiographic controls, the fiber post (Q.P. Fiber Post, Korea) was cemented with a dual-cure cement (G-CEM LinkAce, Japan). The core of the tooth was restored with freehand technique using an adhesive system (Clearfil SE Bond, Kuraray, Japan) and enamel-dentin composites (NE-A2B, Estelite Asteria, Tokuyama, Japan). Finishing and polishing operations were carried out with abrasive discs (Sof-Lex, 3M ESPE, USA) and polishing rubbers.
Results: The patient's tooth 11 was successfully restored using fiber post and composite resin.
Discussion: While a successful and aesthetic result can be achieved in a
single visit with fiber post and direct composite resins used in the restoration of root canal treated teeth with high substance loss. They can be an
alternative to metal posts and indirect restorations with their conservative
and low costs.
