Estelite Sigma Quick and Estelite Asteria (Tokuyama Dental, Japan) are premium composite filling materials with the lowest polymerisation shrinkage in the world and the most natural aesthetic outcome. The material's defining feature is its unique Supra-Nano Spherical Filler technology — every particle is a perfect 0.2-micron sphere. This delivers three key advantages: first, the famous chameleon effect, where the material automatically adapts to the shade of neighbouring teeth and the margins of the filling become practically invisible. Second, the spherical surface scatters light in a way that mimics the natural translucency of enamel. Third, ultra-low shrinkage (around 1.3%) virtually eliminates the risk of marginal gaps and secondary decay. The material is suitable for both anterior and posterior restorations but truly shines in the aesthetic zone — a single layer of Estelite Asteria can deliver a veneer-quality result. Treatment is completed in one session lasting 45–90 minutes; the composite is placed layer by layer under loupe or microscope control and then polished to a mirror finish using dedicated Japanese polishing discs. BadamDent provides a written 3-year warranty on Estelite fillings, with a realistic service life of 10–15 years or more. Adhesively bonded composite restores the tooth's natural strength and insulates it from thermal stimuli. This filling is the ideal choice for patients who put aesthetics first.
