Esthetic Rehabilitation of Congenitally Peg‑Shaped Lateral Incisors Using the Injectable Composite Resin Technique: A Clinical Report

Abstract

This report details the esthetic dental rehabilitation of a patient with peg‑shaped and malformed lateral incisors, conditions that stem from congenital anomalies in tooth formation, using the injectable composite resin technique (ICRT). The ICRT clinical workflow initiates with a smile analysis and precise shade matching, followed by the construction of a diagnostic wax‑up crafted according to esthetic and functional guidelines. Subsequently, a mock‑up is developed to ensure that the planned restorations fulfill the patient’s functional requirements and esthetic expectations. A transparent silicone index is employed to accurately transfer the patient‑approved wax‑up into the mouth, utilizing injectable flowable composite resin. This method enhances treatment predictability and ensures that the final direct restoration precisely reflects the approved design within a reasonable chairside timeframe.
