Upload upper and lower STL files. Get the corrected bite alignment back with a contact map.
10 free scans. No credit card.

When you need to verify
The scanner captured the bite — but was it accurate? Patient didn’t close fully. Bite scan shifted. Soft tissue interference. You’re sending the case to the lab and need to be sure.
Or you have upper and lower arches from different appointments, separate scanners, or a lab case with no bite registration at all.
What OccluTrace does
Upload two STL files
Upper and lower arch, from any scanner, any orientation.
AI computes occlusal contacts
Finds where the teeth should meet based on anatomical landmarks.
Lower jaw repositioned
Rigid transform only. No mesh deformation. Original geometry preserved.
Review and download
Interactive 3D contact map + corrected STL. Ready for CAD or case review.
Results in under 2 minutes. Original geometry is never modified — only repositioned.
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.
~90 secondsInteractive 3D viewer with contact overlay. Toggle before/after. Download the corrected STL.
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.
Standard adult dentition with full arches
Any STL from any intraoral scanner

Partially edentulous arches
Post-operative / surgical cases
Multi-jaw comparison over time
10 analyses included with every account.
