Title: Composite layering: Understanding shading concepts and light interactions to mimic natural teeth
Abstract:
Modern dentistry relies on materials and techniques that replicate the natural appearance of teeth. In the pursuit of creating natural-looking dental restorations, advancements in materials and techniques have significantly improved the optical properties of composite systems while prioritizing mechanical properties, wear resistance, and minimizing polymerization shrinkage. Achieving this balance involves considering filler size, shape, and quantity, as well as monomer composition. Understanding color interactions between composite layers remains a key challenge and the wide array of shades and manufacturers can make it challenging to anticipate the ultimate color of a multi-layered restoration. To achieve realistic dental restorations, it is essential to have a deep understanding of the polychromatic technique in terms of color interaction between composite resin layers and their effect on the overall appearance of the restoration. This presentation provides an overview of the polychromatic layering technique (PLT) while taking into account the optical and mechanical characteristics of dentin and enamel. It also explores how these characteristics align with contemporary composite resin materials. This knowledge serves as a valuable resource for clinicians, assisting them in choosing the most appropriate restorative materials for their specific clinical cases and correlating them with current composite resins which remain the clinical challenge for dentists.
