Dental Scan

The 3D viewer opens on the dental scan: the first three phases turn a raw intraoral scan into a clean, upright model that the rest of your case is built on. You import the arches, orient the model to the bite, and trim the surface.

Open it

Open a patient's dental scan, or a treatment, in the 3D View. The step bar along the top walks you through the phases — Import and Orient first, then on to the teeth. The phase you're on is highlighted there.

Import the scan

On Import, load the two arches:

  • Choose the upper (maxilla) and the lower (mandible) arch files. You can load them in either order.
  • Titan reads .stl, .ply and .obj files. Anything else is refused.
  • As each arch loads, Titan cleans it automatically — it keeps the main piece, closes small holes, and removes a printed base if the scan was a "closed" model.

You need at least one arch to move on. If one is missing, Titan offers Ignore And Continue or Stay And Fix.

Orient the model

On Orient, square the model to the occlusal plane and the midline:

  • Press Detect to orient it automatically. Titan fits the bite plane and the arch's line of symmetry, then fine-tunes with an AI pass.
  • If it needs a nudge, use Rotate 90° or Flip 180°. Reset clears a manual nudge — it does not re-run Detect.
  • You can orient the lower arch on its own when only it is out of place.

Your orientation is saved into the model when you leave the step.

Trim the scan

On Trim, tidy the scan surface with the sculpting tools — close holes and remove artefacts.

It's best to trim after segmentation, so the AI has the detail it needs to identify the teeth. If you start earlier, Titan reminds you; you can wait or correct a small thing now. On the way out, choose Apply to keep your changes or Discard to drop them.

Tips

  • Re-importing an arch replaces its teeth. You can't re-import once a treatment has a printed aligner, or once you've submitted the planning and the lab owns the teeth.
  • If the model sits crooked or half under the floor, press Detect; if the scan can't be oriented automatically, orient it by hand with Rotate and Flip.
  • Import, Orient and Trim each have their own panel on the right with that phase's controls.
