Sumiko Smile Casting //free\\ Page

The goal is to replicate the natural gradation of color found in a human smile. A "Sumiko" aesthetic often emphasizes a softer, more natural integration with the gingiva (gums) and a specific translucency in the incisal edges of the teeth. During the casting and subsequent layering process, the technician must account for how light interacts with the material. Unlike the opaque white of traditional dentures, advanced smile casting utilizes characterization techniques—internal staining and texturing—to ensure the appliance does not appear artificial under varying light conditions.
