Dental arch 3D model for a presentation film

I built this crowded upper dental arch for a short preview of a dental presentation film. The model is my own: no scan, no client file and no stock asset.

The arch has 14 teeth of five types, from central incisors to molars, plus the gum. Each tooth type is a shape written in Python as an implicit surface, with its own crown height, root length and crown profile. I placed every tooth along the arch with its own offset, height, rotation, tip and torque, which gives the high canines, the palatal lateral incisors and the rotated centrals. Marching cubes turns the shapes into meshes: about 760,000 triangles for the teeth and 482,000 for the gum.

Materials, light and the camera move are set up in Blender and rendered in Cycles, with subsurface scattering in the enamel and gum. It is an illustration for films and presentations, not clinical data.
