Study Notes
Orthodontic Treatment and AI
- The most important parts of orthodontic treatment are determining the treatment plan, outcomes, and monitoring patients.
- AI can automate manual work, speed up diagnosis, treatment planning, and assessment of growth patterns.
Automation of Diagnostic Tasks
- Advances in digital data have increased the demand for automating cephalometric analysis and diagnostic tasks.
- Automation aims to reduce time required for analysis, improve accuracy of landmark identification, and reduce errors due to clinicians' subjectivity.
Landmark Identification
- Automatic identification of landmarks has been undertaken using computer vision, AI, and deep learning techniques for 20 years.
- Trained AI algorithms can analyze and annotate cephalometric landmarks on radiological images in a fraction of a second with comparable precision to experienced human examiners.
- However, the usefulness of 3D cephalometric analysis based on 2D cephalometric measurement and landmarks has been questioned.
Cephalometric Superimposition
- More accurate and reliable methods to perform cephalometric superimposition, such as voxel-based superimposition and surface-to-surface matching, have been introduced.
- These methods have resulted in cephalometric landmarking becoming outdated.
Segmentation of Anatomical Structures
- Machine learning and deep learning techniques have been applied for fully automatic segmentation of maxillary and mandibular bones, upper airway, and for skeletal bone age assessment.
- Segmentation is the construction of 3D virtual surface models to match volumetric data, allowing for evaluation of size, shape, and volume of anatomic structures.
- Manual segmentation is time-consuming, tedious, and requires expertise, making automated methods desirable.
Automated Segmentation
- Completely fully automated systems to segment any structure from CBCT images have been developed using AI, particularly convolutional neural networks (CNNs).
- CNNs have led to breakthroughs in CBCT segmentation, especially when compared to previous methods employing general hand-crafted features.
