While clinical dentistry has seamlessly integrated the digital revolution, there is a gap in the technological capabilities of forensic dentistry.The study aimed to compare the superimposition accuracy of two different three-dimensional record formats, namely the intraoral scanner and cone beam computer tomography, in the context of forensic identification.The sample consisted of randomly selected adults (n=10) of both sexes aged between 20 and 50 years. Following the acquisition of data using the Medit i700 wireless scanner and the iCAT Tomograph with InVivo software, the records were analysed and compared through superimposition using Medit Scan Clinic software to assess the technical precision of anatomical identification details.The results obtained through the superimposition of dental and bone records following intra- and inter-observer analysis enabled an accurate comparison and identification of an individual. This method can differentiate between positive and negative matches, achieving exclusion results and offering a potential solution to overcoming the absence of a standardisation procedure in human identification.
虽然临床牙科已经无缝融合了数字革命，但法医学牙科的技术能力仍存在差距。本研究旨在比较两种不同的三维记录格式，即口腔内扫描仪和锥形束计算机断层扫描，在法医学鉴定背景下的叠加准确性。该样本由随机选择的年龄在 20 至 50 岁之间的成年男女（n=10）组成。使用 Medit i700 无线扫描仪和 iCAT Tomograph 结合 InVivo 软件获取数据后，通过 Medit Scan Clinic 软件进行记录分析和叠加，以评估解剖识别细节的技术精度。通过对内部和外部观察者分析后的牙齿和骨骼记录进行叠加，获得了准确的个体比较和识别结果。这种方法可以区分阳性和阴性匹配，实现排除结果，并为解决人类识别中缺乏标准化程序提供了潜在的解决方案。
