Mechanical stength: Greater resistance to fracture and wear. Shade fidelity to the Vita shade guide: Greater predictability of results. Shade stability: Due to less formation of inhibited layer and presence of shade stabilizer in the formulation. Low heat release: Increased comfort for the patient and safe for use on vital teeth. Consistency with reological effect: Adequate viscosity with perfect reproduction of details. Balanced formula: Proper combination of monomers provides excellent working time and ease of product removal during the elastic phase.
