Zirconia Blanks Compared
Aidite white vs. Polaris multilayer — the real difference is technician time, not just price.
These two blanks represent two different philosophies, not two different quality tiers. The Aidite Superfect Zir HTW is a uniform, single-shade white blank; the Polaris 5D is a multilayer blank with a built-in color gradient.
With white zirconia, the technician builds the final shade with staining liquid. You get full manual control and lower material cost — but it takes more chair time and the result depends on the technician's skill. With multilayer, the gradient comes from the blank itself; it frees up technician time but costs more.
Simple economics: for anterior, esthetic-heavy work, the time multilayer saves usually outweighs the price gap. For high-volume posterior work, white stays more economical. We break down the conceptual difference further in our dedicated article.

Which should you choose?
If you do high-volume posterior work
Aidite white ends up more economical; shade sensitivity is lower in the posterior zone.
If you do anterior, esthetic work
Polaris multilayer, with its natural gradient, gives better results with less chair time.
If you have a skilled staining technician
White gives you full control over shade and effects — something multilayer decides in advance.
One thing both share
The shrinkage factor is printed on each disc and must be entered into the CAM software before milling; the number can vary by batch.

FAQ
Which one is better?
Neither is strictly better. For high-volume posterior work, white is more economical; for anterior esthetic work, multilayer gives a better result with less time.
How big is the price difference?
Pricing for each size is published separately on the white block page and the multilayer page. Message us on WhatsApp for the current price.
Does multilayer also need staining?
In most cases no — the gradient comes from the blank itself. For an exact shade match, light localized staining can still be applied.
Are both compatible with my milling machine?
The 98mm diameter is standard and works with most benchtop machines. Tell us your machine model and we'll confirm the holder system.
