AI-DRIVEN FORENSIC INNOVATION
Revolutionizing Forensic Odontology: AI-Driven 3D-2D Dental Superimposition for Human Identification
This research introduces two innovative AI-driven methods for dental superimposition, drastically improving the speed and accuracy of human identification in forensic scenarios. By automating a traditionally manual and subjective process, the technology offers significant advancements for disaster victim identification (DVI) and cases with limited ante-mortem data.
Executive Impact
Automated dental superimposition dramatically enhances forensic identification capabilities, offering unparalleled speed and reliability in critical DVI scenarios. This technology significantly reduces processing time and increases accuracy, freeing up expert resources for more complex analyses.

Introduction: The proposed AI superimposition methods significantly enhance DVI efforts, particularly in scenarios where traditional ante-mortem dental records are scarce or non-existent.
Challenge: Manual dental comparison is time-consuming, subjective, and prone to errors, especially when dealing with large numbers of victims or limited AM data (e.g., social media photos). Perspective distortion in photos further complicates accuracy.
Solution: Automated 3D-2D image registration, using either precise landmarks or region segmentation, replicates the AM image with the PM 3D model. This provides an objective, quantitative score of morphological correspondence, streamlining the comparison process.
Results: The methods achieve an average ranking of 1.5-1.6 for correct matches across 142 samples, dramatically reducing the pool of potential matches. The region-based approach shows a Cur score of 0.2316, indicating high reliability comparable to established forensic identification systems like AFIS.
Key Takeaway: AI-driven dental superimposition transforms DVI by providing a rapid, objective, and reliable method for identifying victims using easily obtainable photographic evidence.
