Setting insertion axis

When this dialog is displayed

You will not always get prompted for the insertion axis. The software can accurately autodetect the proper insertion axis in the vast majority of cases. You will be asked to check the detected insertion direction in the following cases:

  • When constructing bridges for 3-axis or 4-axis milling
    • For 3-axis milling, it is required - due to production constraints - that all teeth within a bridge share the same insertion axis. The detected insertion common axis is shown to the user, who can then help to optimize this sometimes difficult decision
  • When the software has doubts about the insertion axis it auto-detected
    • Even for single crowns/copings, or for bridge elements in 5-axis milling, you are sometimes prompted to verify/correct the detected insertion axis. This is usually the case when dealing with dubious preparations (e.g. when the margin line lies within an undercut area).
  • For all inlay constructions


Checking/editing the insertion axis

The software will present you its auto-detected insertion axis, by adjusting the viewpoint so that you look onto the preparation(s) in the direction of insertion. Additionally, undercut areas will be marked with a color scale.

Setting a new insertion axis

To change the insertion axis, rotate the view so that you look onto the preparation(s) from your desired insertion direcion. Then, click button [2] to set this as new insertion axis. The undercut visualisation will be updated.

Applying a common insertion axis for several constructions

In 5-axis or laser melting mode, the software allows different insertion directions for parts within a bridge. To enforce the same insertion axis for several parts, click on the respective tooth within the tooth selection control. For example, in the above screenshot – which prompts you for the insertion axis of tooth 23 – click on the tooth symbol 24 to ensure that teeth 23 and 24 share the same insertion axis. Click on 24 again to undo.

Check „unique insertion direction for bridges“ to enforce a common insertion axis for all parts of the currently edited bridge (default in 3-axis mode).

Warning In 3-axis mode, uncheck this box only if you really know what you're doing.

Click „Next“ in the wizard window when done, to proceed to the next step.
