Orthodontic alignment - 3D treatment animation (concept)

This is a self-initiated concept animation, not a clinical case or a treatment plan. In one continuous camera move, a crowded upper arch (blocked-out canines, palatal laterals, rotated centrals and premolars) becomes a natural aligned arch. The arch widens slightly and the front comes forward to make space, then each tooth slides and seats on its own schedule while the molars stay put. The gum is rebuilt for every frame from the posed teeth, so it follows them. At the end a 0.62 mm clear aligner appears on the aligned teeth and a light strip glides across the arch.

Teeth, gum and aligner are my own procedural models (Python, numpy, marching cubes), rendered in Blender Cycles with subsurface scattering. I checked every pair of neighbouring crowns for intersections during the alignment. 19 s, 1920x1080, 30 fps, silent.
