One-step fiber post cementation and core build-up in endodontically treated tooth: A clinical case report

José Mauricio Dos Santos Nunes Reis et al. J Esthet Restor Dent. 2020 Jan.

Abstract

Objective: This clinical case report addresses the step-by-step of the application of a core-and-post system that uses a single resin composite material to fiber post cementation and core build-up in a maxillary left central incisor.

Clinical considerations: The literature reports several materials and methods for the restoration of endodontically treated teeth with coronal destruction that require an intra-radicular fiber post for the core build-up. The present case report describes a core-and-post or "monoblock" technique. A dual resin composite (Core-X Flow; Dentsply DeTrey) highly filled material and cement was used for luting the fiber post (Blue X-Post) and build-up the core structure in an easy application.

Conclusions: The "core-and-post" technique that uses a single material system protocol minimizes the material interfaces, steps of procedures, and chair-time in comparison to conventional techniques.

Clinical significance: The use of different materials for post cementation and core build-up requires more steps, which increases the chair-time and number of interfaces among the materials. Since the "monoblock" technique uses only one material, it can streamline the clinical procedures, thus, saving time and materials. Moreover, techniques based on core-and-post systems are easily applied, versatile, and esthetics, and can be applicable to posterior and anterior teeth.

Keywords: core build-up; core-and-post system; restorative dentistry; tooth crown.
