The widespread use of dental implants has created new opportunities for forensic identification based on the analysis of material composition and technological characteristics of implant systems that remain preserved under severe post-mortem and thermal conditions.
To evaluate the potential of elemental analysis of dental implants for forensic personal identification, considering alloy variability, surface modifications, and resistance of chemical profiles to extreme exposure.
The study involved titanium and zirconia implants examined using X-ray fluorescence spectroscopy, scanning electron microscopy with energy-dispersive detection, inductively coupled plasma mass spectrometry, and phase analysis to determine bulk elemental composition and surface characteristics.
Quantitative ratios of titanium, aluminum, vanadium, niobium, zirconium, and trace impurities form stable chemical signatures enabling differentiation between commercially pure titanium, alloyed systems, and zirconia-based implants. Preservation of core elemental composition after thermal exposure supports their forensic applicability.
Elemental analysis of dental implants constitutes an independent and reproducible forensic identification tool, and its integration with morphometric and radiological data enhances the evidentiary reliability of expert conclusions.
