71mm zirconia block features 6 layers of natural color transition, matching color gradient of natural tooth from cervical to incisal. Translucency changes from 57% in incisal to 43% in cervical. It shows gradient decrease, achieving life-like transparency of natural tooth enamel while low transparency in cervical has effective opaque. Strength gradient is from 600 Mpa to 900 Mpa. It achieves low strength in occlusion and causes no harm to opposing dentin. High strength in base part realizes long bridge restoration.
