One (Abrasive) is Enough

The AccuFLo

The AccuFlo is our latest MicroBlaster.

We recently discovered something quite cool.

Our AccuFlo® blaster, when combined with our Hi/Performance nozzle, provides enough velocity to remove all of the investment casting around a dental bridge and crown using glass bead abrasive. Yep, you read that right: ALL of the investment casting. This is kinda big news for dental labs.

Traditionally, divesting bridges and crowns is a two-step process performed with two different abrasives and our Dual-Tank MicroBlaster®. Operators start with aluminum oxide to remove the bulk of the investment casting. Then, they switch to glass bead, to remove investment casting touching the bridge or crown. Glass bead has a spherical shape and is not sharp enough to damage the integrity of the bridge and crown.

But now we know: the two-abrasives approach may include one abrasive too many.

The Benefit of a Single Abrasive

The single-abrasive approach simplifies and streamlines the removal process. It means no second tank! No second tank means one less nozzle, one less abrasive hose, less blaster maintenance, and the list goes on.

Take a Look!

What’s a discovery without a little video evidence?
