Abstract
Introduction: Forensic science develops diverse technologies for the identification of corpses, but in some cases these procedures can be very expensive and unreliable in the case of cremated bodies. This research aimed to describe the metallographic changes in a titanium implant subjected to different temperatures and the evaluation of its potential use as a forensic descriptor. Materials and methods: Fifteen titanium mini implants with an identification code were made, inserted into pork jaws and subjected to temperatures of 200 ° C, 800 ° C and 1000 ° C, samples were recovered and analyzed were performed by optical microscopy and electron scanning microscopy. Results: It was possible to characterize the microstructure for each temperature, an increase in the oxide layer was observed with the increase of each temperature. Conclusion: It is possible to use dental implants as a forensic identifier.
