Fourth-generation intraradicular posts for the aesthetic restoration of anterior teeth.

Endodontically treated teeth have been traditionally restored with cost-metal posts prior to receiving aesthetic care. Due to the difficulties associated with early posts, resources have been invested to develop biocompatible endodontic posts capable of satisfying functional and aesthetic criteria. These initiatives have resulted in the introduction of carbon-based and glass-fiber posts with translucencies and moduli of elasticity closely approximating that of the dentin for use in adhesive dental procedures. This article demonstrates the rationale and application of translucent glass-fiber posts for the restoration of pulpless teeth.
