Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Computer Vision

Background:

  • Machine learning (ML) and artificial intelligence (AI) are pivotal in medical image analysis.
  • Supervised ML enables prediction of anatomical structure segmentation in new patients.
  • This research focuses on AI for dental imaging, specifically 3D tooth modeling.

Purpose of the Study:

  • To develop and validate a deep learning algorithm for automated 3D surface model creation of human teeth.
  • To assess the algorithm's performance in segmenting dental structures from cone-beam computed tomography (CBCT) scans.

Main Methods:

  • Utilized a multiresolution dataset for training and validation.
  • Employed random partitioning for patient data allocation: 140 for training, 40 for validation, and 30 for testing.
  • Evaluated model performance using various metrics to ensure robust assessment.

Main Results:

  • The teeth identification model achieved 87.92% ± 4.43% accuracy on the test set.
  • The general teeth segmentation model demonstrated superior performance with 93.16% ± 1.18% accuracy.
  • These results highlight the effectiveness of the developed deep learning approach.

Conclusions:

  • The study validates the efficacy of AI in dental imaging analysis.
  • The developed algorithm provides a promising foundation for automated and precise dental segmentation.
  • Future advancements in AI-driven dental diagnostics and treatment planning are anticipated.
