中文摘要：

目的：建立古人类牙标本三维模型数据库，以期实现牙标本三维影像保存和牙体解剖形态的数字化资源共享。方法：使用Micro-CT对517个西安地区出土的2000年前人牙标本进行扫描，Mimics10．01软件三维重建后，采用Access2007软件建立数据库。结果：建成后的数据库使用方便，系统运行稳定，录入和查询检索简单快捷。数据库通过与Mimics三维重建软件相链接，清晰显示各牙三维模型形态，有助于牙体形态学研究。结论：Micro-CT扫描和Mimics软件三维重建技术能准确地构建古人类牙标本的三维模型；通过Access2007软件能便捷地建立数据库，并将牙三维模型集中存放，便于数据的查询和资源的共享。

英文摘要：

AIM ： To establish a 3 dimensional （3 D） model database of tooth samples of ancient human for the accomplishment of the digitized imaging conservation and sharing the digital resources of tooth anatomical struc- tures. METHODS： 517 teeth from the human remains of 2000 years ago unearthed in Xi＇an were scanned using Mi- cro-CT, then they were reconstructed into 3D images and saved by Mimicsl0.01 software. The database construction was based on Access2007 software. RESULTS： The established database runs stably, data entry and inquiry system is simple and convenient. By linkage with Mimics10.01 software, every 3D model of the teeth is accurate. CONCLU- SION： The established 3D model database can be used for morphologic study.
