Derivative by DentalKnowledgeBase, 2026-09-22, under CC BY-SA 4.0.
28 teeth, 3 disconnected gingiva components, mandible and 2 maxilla components.
Only named dental structures extracted. No inner ear or kidney structures.
Changes: subset extraction, rigid coordinate conversion and uniform unit scale,
one Catmull-Clark subdivision for presentation, smooth normals, separate loose
gingiva components, binary format, display materials. Jaw separation in the viewer
is an illustrative translation and NOT a physiological movement simulation.

The model has no third molars, pulp, canals or separate enamel/dentin volumes.
Do not interpret external crown/root material boundaries as volumetric segmentation.
No verified age/sex cohort, dimensional accuracy or expert approval is claimed.
The authors have not endorsed this adaptation. Original source notice included.

The manifest records source SHA-256 hashes, source URLs, revision and transformations.
Both derivative binary and manifest are downloadable without DRM.
CC license covers this anatomical derivative, not unrelated application code.
This engineering assessment is not a persisted rights approval or academic release.

Neurovascular extension (2026-09-22): six named nerve surfaces and eight named
arterial surfaces, from NervousSystem100.fbx and CardioVascular41.fbx at the same
upstream revision. See neurovascular.json for exact names, source hashes and URLs.

Nerve/artery additions: original mesh topology, same rigid coordinate/unit
conversion as teeth, smooth normals, binary packing, illustrative yellow/red
materials. No subdivision, generated terminals or inferred tooth connections.
Not included: veins, capillaries, intrapulpal nerves/vessels, complete dental
terminal branches. Preserve source jaw position while these layers are active.
