Abstract:

Traumatic dental injuries (TDIs) are highly prevalent among children and adolescents and often involve crown fractures of the maxillary incisors, which represent the most frequent type of trauma in the permanent dentition. Given the potential biological and psychosocial consequences—ranging from pulp necrosis and disturbances in maxillofacial development to reduced quality of life—prompt and predictable restorative interventions are essential. Direct composite restoration remains the treatment of choice in young patients when the fractured fragment is unavailable, owing to its conservative nature, favorable esthetic outcomes, and ability to preserve remaining tooth structure. This case report presents a minimally invasive restorative approach for the management of an uncomplicated crown fracture of a maxillary central incisor using a silicone index to accurately reproduce the original tooth morphology. The silicone key technique facilitates precise palatal shell formation, enables controlled layering of composite resin, and reduces operative time—factors that are particularly advantageous in pediatric and adolescent patients who may have limited treatment tolerance.
