Intraoral scanners capture upper and lower arches independently. Aligning them into correct occlusion by hand is slow and imprecise.
OccluTrace does it automatically.

The problem
Every intraoral scanner gives you two separate meshes. To place them in occlusion, you either take a physical bite scan (adds time, material, patient discomfort) or align manually in CAD (tedious, subjective, error-prone).
For diagnostic models, study casts, and remote lab work — there’s no quick way to get the bite right.
What OccluTrace does
Upload two STL files
Upper and lower arch, from any scanner, any orientation.
AI identifies contact zones
Trained on 1,300+ ground-truth clinical scans with verified occlusion.
Rigid alignment computed
The lower jaw is repositioned. No mesh deformation. Original geometry preserved.
Download corrected result

Workflow
Drag two STL files into the browser. Auto-detects upper vs lower. Exclude areas if needed.
STL formatNeural network identifies anatomical contact zones. RANSAC + SVD computes the rigid transform.

STL + contactsHonest status
OccluTrace is a new tool. The model improves with every scan we process. Some cases align perfectly. Others need refinement. We’re transparent about that.
