The 28 permanent teeth (central/lateral incisors, canines, first/second premolars and first/second molars) and the upper and lower gingiva originate from BodyParts3D 4.0. These are the separate FJ1252-FJ1281 meshes in the official 99% reduction archive:
https://dbarchive.biosciencedbc.jp/data/bodyparts3d/LATEST/isa_BP3D_4.0_obj_99.zip

We obtained the corresponding high-resolution binary meshes and part identifiers through OMFAtlas:
https://github.com/choxos/OMFAtlas/tree/main/public/models/high-resolution

Changes made for the website: selected the 28 permanent tooth meshes and two gingiva meshes; uniformly scaled and translated their common coordinate system; converted packed normals to float32 and triangle indices to uint16; repacked them into one browser binary. Individual tooth anatomy and relative placement were not sculpted or changed. The interactive view may visually separate the upper and lower arches to make selection easier.

For display, the renderer crops the hidden ends of roots at the gingival base. This display crop does not change the distributed meshes.

The model is a general anatomical illustration for navigating a dental enquiry. It is not a patient scan or a diagnostic tool. The four third molars (FDI 18, 28, 38, 48) are absent from the source dental assembly and are therefore not shown in 3D.
