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.
