Precision Meets Artistry: The Silicone Key Technique Restoring a fractured central incisor isn’t just about filling a gap; it’s about reconstructing biomechanics and optical harmony. Why use a Silicone Index? By creating a mold from a diagnostic wax-up (or the original tooth), we can: 1️⃣ Establish the exact palatal wall thickness. 2️⃣ Ensure perfect incisal edge positioning. 3️⃣ Control the layering of composite increments to mimic natural enamel and dentin.
