Deep Learning for Dental Imaging

About

We are a small independent research team focused on medical imaging analysis using deep learning. Our work applies state-of-the-art neural network architectures to dental imaging analysis.

Our research spans two complementary domains: Endodontics (3D CBCT tooth segmentation and root canal measurement) and Prosthodontics (2D panoramic X-ray analysis for edentulous region segmentation).

Demos

Explore our research through interactive notebooks. Each demonstration allows you to upload your own dental images and observe the segmentation pipeline in action.

Panoramic X-ray Analysis

Prosthodontics

Multi-stage pipeline combining YOLO and nnU-Net for comprehensive panoramic dental X-ray analysis. Identifies edentulous regions and segments present teeth with physical measurements.

  • Bone structure segmentation
  • Edentulous zone detection
  • Present teeth segmentation with FDI numbering
  • Physical measurement estimation
Launch Demo

3D CBCT Tooth Segmentation

Endodontics

Dual-branch nnU-Net V2 architecture for tooth instance segmentation in cone-beam CT (CBCT) scans. Provides individual tooth identification with FDI numbering system and 3D visualization.

  • Individual tooth instance segmentation
  • FDI tooth numbering classification
  • Interactive 3D mesh visualization

Instance Segmentation

Dual-branch network combining semantic segmentation with instance discrimination for individual tooth identification.

Multi-Modal Pipeline

Integrates YOLO detection with nnU-Net segmentation for comprehensive analysis of 2D panoramic radiographs.

Connected Component Analysis

Post-processing techniques for instance separation and anatomical structure identification.
