Brief summary: The aim of this study was to conduct a clinical trial utilizing a modified split-mouth, double-blinded, randomized strategy to clinically assess template assisted one shade structural colored versus universal multi-shade direct composite veneers

Detailed description: The superior mechanical qualities, superb aesthetics, and versatility of resin-based composites (RBCs) make them popular choices for direct restorative applications. Compared to their predecessors, nanocomposites have shown superior qualities since nanotechnology was introduced in the production of dental RBCs.

A restoration's aesthetic integration is mostly the result of its chromatic characteristics. Pigments included in the composition of the restorative material typically control the selective reflection of wavelengths to emulate the natural tooth. In order to better reflect the broad color range that characterizes real dentition, RBCs have more recently employed the phenomena of "structural color" .

Thanks to the novel property of resins, color differences between the tooth and the restoration are eliminated or balanced out as perceived color of a region moves toward the color of the surrounding area . Additionally, as opposed to multi-shade RBCs, single-shade RBCs eliminate the need to select between various resin shades, streamlining the color choosing procedure and cutting down on time lost during the clinical resin selection process. The Vita Classic Shade Guide's shades can all be matched with these materials.
