摘要：

背景：研究表明目前所有应用离体牙的实验，因离体牙之间大小、形态、质地、硬度等方面的差异，会对实验结果造成误差，而采用计算机辅助设计/计算机辅助制造技术建立标准离体牙模型可以减小相关实验的误差。
目的：采用计算机辅助设计/计算机辅助制造技术构建上颌中切牙的离体牙标准测试模型，并使用激光快速成型技术对树脂材料进行加工制作离体牙、预备体和全冠模型。
方法：选择一颗完整上颌中切牙，进行表面处理，表面喷DPT-8显影溶液，并采用Freedom扫描软件，对离体牙、预备体进行扫描，在计算机中获得三维模型，并进行模型设计，获得冠的三维模型。离体牙、预备体和树脂全冠三维模型完成后，打开Hyperdent软件，进行离体牙、预备体和树脂全冠模型的制作。
结果与结论：实验成功建立了离体牙、预备体和树脂全冠的三维数值模型和树脂实体模型，具有良好的几何相似性。提示在以后的实验室研究中，可以采用计算机辅助设计/计算机辅助制造技术获得具有良好几何相似性的离体牙标准测试模型，减少因离体牙之间因大小、形态、质地等方面对实验产生的误差。

Abstract:

BACKGROUND: Studies have shown that because of the differences in tooth size, shape, texture, hardness and the others, the extracted teeth can cause some error to the experimental results. Computer aided design/computer aided manufacture (CAD/CAM) technology used to establish the standard test model can reduce the related experimental error.
OBJECTIVE: To establish the standard test model of maxillary central incisor with CAD/CAM technology, and to make the resin models of the extracted tooth, preparation and full crown by using the laser rapid prototyping technology in vitro.
METHODS: A complete maxillary incisor was selected, and the tooth surface was sprayed with the DPT-8 development solution. The three-dimensional models of the extracted teeth and preparation were completed with the Freedom scanning software, and the three-dimensional model of the full crown was finished through the model design. Resin models of the extracted teeth, preparation and full crown were made by using the Hyperdent software.
RESULTS AND CONCLUSION: The three-dimensional and resin models of the extracted teeth, preparation and full crown were successfully established in vitro, and had good geometric similarity. In laboratory studies, we can use CAD/CAM technology to obtain the standard test model of the extracted teeth with good geometric similarity, and reduce the experimental error.
