Mimic nature's light dynamics with the SHT Block's 46% translucency – precisely calibrated to replicate enamel's opalescence. The material's 1300 HV10 hardness creates lifeless surface texture, while proprietary polishing protocols achieve Ra<0.2μm surface roughness. Compatible with all major staining systems (Vita 3D-Master, Chromascop), it enables seamless shade transitions from cervical to incisal zones.
Optical Science
• Light Refraction Index: 2.20 @ 589nm (vs. enamel: 2.17)
• Opalescence Parameter: 15.2 (vs. natural teeth: 12-18)
• Fluorescence: 4.2% (eliminates "dead tooth" effect)
Clinical Validation
98% shade match accuracy (n=500 cases)
0% gingival discoloration at 5-year recall
Patient satisfaction: 96% "indistinguishable from natural"
