Abutments fit first try.

For printed prototypes. Select the ti-base channels in your STL, set the clearance to a hundredth of a millimetre, and export a new STL. Any implant system, any printer.

Four steps to a prototype that fits

Your CAD software has no offset for a printed prototype, so the channel prints at the exact size of the ti-base and the ti-base does not go in. EZ Offset adds the space back.

1

Load your STL

Open the file you exported from exocad or any CAD. Or press Try the demo and follow along with a real 12-unit hybrid.

2

Select the channels

Look into a ti-base channel and click its inner wall. The whole channel turns gold. Repeat for each channel.

3

Set the clearance

Positive values loosen the fit, negative values tighten it. Radial only moves the walls and keeps the seat height.

4

Export

Export writes a new STL. Your original file does not change.

Try it on the demo case

The whole idea, on one slider

One ti-base channel, in cross-section. Drag the slider, then switch modes.

Offset
0.000mm

Drawn oversized so the change is easy to see. The math is exact at any value.

Check it like you would in CAD

Turn on the section view and the cut shows the channel in profile, so you can see the new wall before you print.

Your original channelThe offset wall

Only the selected surfaces move. The triangle count stays the same and every other face stays where it was. With Radial only the walls move and the seat stays at its height. In Arch mode the cut stays square to the arch as you slide it along.

The demo case cut through one channel, Radial only: the walls move from the opening to the bottom of the cavity, and the bottom stays at its height. The offset is drawn five times larger here so you can see it; export always uses the true value.

Model modeBETA

Rebuilds a whole scan with space that varies across the surface, then hands you a closed model to take straight back into exocad.

  • Paint zones with a brush, a lasso, or a grow that stops at a crease. Each zone gets its own value.
  • Each zone edge either drops straight down the insertion direction or ramps back onto the scan.
  • You choose which undercuts get blocked out. Tissue you leave alone stays exactly as scanned.
  • Open scans close with a flat base and a land. Hollow it if you print it.
  • Bar overdentures: offset and block out the bar and the housings only, and keep the tissue. Find the rail and place clip housings (beta).

It carries the beta label while it proves itself on more real cases. There is a Report a bug button inside the tool.

A drawing of a cut through a bar with a locator housing. Paint the bar and the housing, give each its offset, and block out under them. The tissue is not painted, so it stays exactly as scanned.

Questions

Do my case files leave my computer?

No. All the work happens in your browser, on your computer. Your files are never sent anywhere.

Which implant systems?

All of them. EZ Offset works from the geometry in your file, not from a parts library. If your CAD exported it, EZ Offset can offset it.

Does it change my original file?

No. Export always writes a new STL, with the mode and value in the file name.

Which files work?

Binary and ASCII STL, straight from exocad or any CAD.

How many computers?

Each license works on up to 3 devices, and you can remove a device yourself at any time.

Refunds?

There are no refunds, because the free trial runs every tool except export. Test it on your own cases first.
