摘要

导读:法医科学开发了多种鉴定尸体的技术,但在某些情况下,这些程序可能非常昂贵,而且在火化尸体的情况下不可靠。本研究旨在描述钛种植体在不同温度下的金相变化,并评估其作为法医描述符的潜在用途。材料与方法:制作15个带有识别码的钛微型植入物,置入猪爪中,分别经过200℃、800℃、1000℃的温度处理,回收样品,通过光学显微镜和电子扫描显微镜进行分析。结果:可以表征各温度下的微观结构,氧化层随温度的升高而增加。结论:种植体作为法医鉴定物是可行的。

Descripción Metalográfica de implantes de Titanio calcinados y su aplicación como descriptor forense
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.
