3Shape FDI 16 Meshes from Intraoral Scans

Version update 2024-02-16: Changed test data to also be from european scans.

The FDI 16 tooth mesh dataset including original meshes and exact data used in the original VF-Net paper. All scans are fully anonymized and donated by 3Shape.

The data contains 4844/1465/1423 meshes and point clouds for train/val/test respectively for deep/machine learning. All data stems from clinics based in Europe. The scans were collected using TRIOS scanners, and primarily the TRIOS 3 model. The data serves as a new and highly relevant use case for computer algorithms for 3D objects.

Each scan contain:

• "_mesh.ply" suffix file: A PLY file of the original segmented tooth mesh
• "_point_cloud.ply": The vertices and facet midpoints of the mesh as a point cloud
• "_curvature_edgedistance.dat": A binary file including first the curvature of each point in the "_point_cloud.ply" and subsequently the djikstra distance to nearest edge vertex.
