What are EVE Diapol RA polishers used for?

They are diamond polishers for porcelain and ceramic restorations, used in a contra-angle (RA) handpiece to re-polish crowns, veneers and inlays chairside after an adjustment.

Can I polish porcelain in the mouth without re-glazing?

Yes. Used in the full coarse, medium and fine sequence, they bring the adjusted surface back to a glaze-like shine without sending the restoration to the lab or firing it again.

What is the correct grit sequence?

Coarse first, then medium, then fine. Each step removes the scratches of the one before it. Skipping a step reduces the shine and leaves a rougher surface.

How do I tell the grits apart?

By color: blue is coarse, pink is medium and gray is fine. The last letter of the catalog number (C, M or F) also shows the grit.

What speed should I use?

The recommended range is 7,000 to 12,000 RPM in a contra-angle (RA) handpiece, with light pressure and constant movement.

Which shape should I choose?

Use the wheel (RD-RA-8) or spiral wheel (RD-RA-14) for broad and curved surfaces, the point (RD-RA-16) for fissures and occlusal anatomy, and the cup (RD-RA-17) for convex surfaces and cusp tips.

What sizes are the RA polishers?

Per the product chart: wheel 11 x 2 mm, spiral wheel 14 x 1.6 mm, point 4 x 10 mm and cup 6 x 7.5 mm.

What is in the introduction kits?

Introduction Kit 1 (RDRAKIT1) contains 9 polishers. Introduction Kit 2 (RDRAKIT2) contains 6 spiral (Twist) polishers. Single polishers are packed one per pack.

Can I use them on lithium disilicate or zirconia?

They are made for porcelain and glazed, layered ceramics. For lithium disilicate (E.max), the EVE Diapro polishers are the dedicated choice, and monolithic zirconia is best handled with a zirconia polisher.

What is the difference between the RA and HP versions?
