3D Teeth Landmark Detection

Interactive results from a Point-Transformer-v3-style model that detects six classes of anatomical landmarks (mesial, distal, cusp, inner, outer, facial axis) directly on 3D intraoral scan point clouds — no tooth segmentation stage.

Developed during a research internship at the National Dental Centre of Singapore; trained and evaluated under the official 3DTeethLand — MICCAI 2024 protocol (lower arch mAP 0.536 / upper 0.553).

Weights, code, and usage instructions: kartikbathla/ptv3-dental-landmark-detector.

Research prototype — not a medical device.
