The comparison of dental morphology and restorative work for human identification has been well documented. This case study involved documentation of osseointegrated and clinically restored dental implants following cremation.
The mandible and the maxilla were excised from a head containing implants and cremated. The remains were retrieved, digital and radiographic images were taken and elemental analysis undertaken. The brand of implants was identified utilizing web based search engines. A prosthodontist, known to commonly use this implant system, was approached to ascertain possibilities that matched the data given.
Following cremation the implants were identified and a prosthodontist was able to identify the deceased. Two implants in the maxilla had dehiscences on their buccal surfaces, which could not be detected by periapical radiographs.
Dental implants osseointegrated and restored with a prosthetic superstructure were recognizable following severe incineration. It was possible to trace back the identity of the unknown victim to a prosthodontist. Bone dehiscences discovered in this study highlighted how two-dimensional radiographs may not reveal lack of bone support.
牙齿形态和修复工作在人类身份识别中的比较已有充分记录。本案例研究涉及火化后骨结合且临床修复的牙种植体的记录。
从含有种植体的头部切取下颌骨和上颌骨并进行火化。找回遗骸,拍摄数字图像和射线照片,并进行元素分析。利用网络搜索引擎识别种植体的品牌。联系一位已知常用该种植体系统的口腔修复医生,以确定与所提供数据相符的可能性。
火化后识别出了种植体,一位口腔修复医生能够识别出死者。上颌骨中的两枚种植体颊侧表面有骨裂开,根尖片无法检测到。
在严重焚烧后,骨结合并用修复性上部结构修复的牙种植体是可识别的。有可能将身份不明受害者的身份追溯到一位口腔修复医生。本研究中发现的骨裂开突出表明二维射线照片可能无法显示骨支持的缺失。
