GC America’s Initial ZR Disk program is the premium end of the USDD zirconia shelf — 52 SKUs built around the ML ELITE multilayer plus ST, HT and UHT translucency grades, inside the same GC ecosystem as the Initial layering ceramics your technicians already use.
Each series below is a separate blank family with its own translucency behaviour and its own price band. Thickness and shade are selected inside the series.
Send us your indication split — posterior units, anterior singles, long-span frameworks — and a USDD lab specialist will map it onto the GC America range and price it.
Every figure in this table is read from the live US Dental Depot catalog listing for GC America. Where a value is not published by the manufacturer it is left blank rather than estimated.

Zirconia is not interchangeable at the furnace. Ask us for the published ramp, dwell and cool-down for the exact series you are considering, and we will send it before you order.
Honest trade-offs. Every zirconia brand is a compromise between translucency, strength, price and catalog depth — here is where GC America sits.
Send your current disc invoice. We will line it up shade for shade and thickness for thickness against this range and show you where the difference actually is.
Six buyer profiles and the disc decision each one usually lands on.
Aconia ST-PRE and GUSROM 3D PREMIUM are the lowest cost per disc in the lineup with full shade coverage.
VITA Dental Direkt DD cubeX2 ML and GC Initial ZR ML ELITE — the two most controlled multilayer gradients USDD carries.
Look at 22–25 mm blanks: Aconia, DIGITECH and MIIYEN all publish 25 mm; Aconia goes to 30 mm.
Buy in small counts of 14–16 mm pre-shaded multilayer. UP3D 4D Multilayer is matched to UP3D mills you may already own.
VITA Dental Direkt and Amann Girrbach ZOLID both span monolayer through high-translucency multilayer in one ecosystem.
Test GUSROM or LUMIX against your current sintering profile on a single disc before switching a shade family.
The six variables that decide whether a blank fits your mill, your furnace and your case.
Nine of the ten brands USDD stocks are built on the 98.5 mm blank with a standard step. Thickness is the variable that changes, not diameter — so a disc that fits one open-system mill usually fits the next.
12–14 mm covers single crowns and thin veneers. 16–18 mm is the workhorse for bridges and multi-unit anteriors. 20–25 mm is what you need for full-arch, implant bars and long-span frameworks.
Multilayer (4D / ML / gradient) discs carry shade and translucency transitions already inside the blank, so an anterior crown comes out of the mill closer to final. Monolayer pre-shaded discs cost less and stain up predictably.
Higher yttria content buys translucency and costs flexural strength. High-translucency 4Y/5Y layers suit anteriors; 3Y-TZP high-strength layers belong under posterior and long-span work.
Pre-shaded blanks remove the colouring-liquid step, the drying wait and the shade drift that comes with it. Every brand in this lineup is available pre-shaded across the VITA classical range.
Zirconia is not interchangeable at the furnace. Each brand publishes its own ramp, dwell and cool-down. Running brand A's schedule on brand B's disc is the fastest route to a cracked case.
