Basic data of the three-demensional analysis as for the preservation form of a three-dimensional image, the applied field like the voxel model, the surface model (solid model), and the resin replica model, etc. separates into many topics. It was thought that the standardizaion of the file format which contained all those image informations was impossible.The preservation of the voxel model by the geometry file was excellent. The surface model (solid model) was DXF file, VRML file, and a wavefront file type or, it was ascii file type. Data layout which we had used extended to many file type in this time. But STL file is from a relation standardized in an industrial field to standard data layout in the file for the laser handed resin replica system output.In the image data of X-ray CT scanner, DICOM3 was an intemational standard in fact. It was thought that the method of the shape added to the image data of the DICOM3 from appending as another file of the data of coordinate axis, which was used at the three-dimensional data analysis, was excellent in respect of interchangeability with the medical treatment image for the diagnosis.The image data of the information of dental cast model was advantageous file format, which was an original data file form (DNT : UNISN Co.Ltd.). This DNT file format was used to be advantageous of the dosage of the file and I thought the data transfer in which the network, because the one side dental cast model was only 500KB.The application program software, that the display and the measurement of the dental cast model data, are newly developed on the Microsoft Windows System by the cooperation of UNISN Co.Ltd. Which are concerning the processing of the three-dimensional data of the dental cast model.

关于三维图像的保存形式，三维分析的基本数据、像体素模型、表面模型（实体模型）和树脂复制模型等的应用领域分成许多主题。以前认为包含所有这些图像信息的文件格式是不可能实现的，而几何文件对体素模型的保存是极好的。表面模型（实体模型）是VRML文件、VRML文件和波前文件类型，或者是波前文件类型。数据布局，我们已经使用的扩展到许多文件类型在这个时候。而STL文件是从一个工业领域的关系标准化到激光手作树脂复制系统输出文件中的标准数据布局，在X射线CT扫描仪的图像数据中，DICOM 3实际上是一个国际标准。在三维数据分析中使用的将形状作为坐标轴数据的另一文件附加到DICOM 3的图像数据中的方法，在与用于诊断的医疗图像的可互换性方面被认为是优秀的。牙模型信息的图像数据是有利的文件格式，其是原始数据文件形式（DNT：UNISN有限公司）。由于单侧牙体模型只有500 KB，采用DNT文件格式有利于文件的用量和数据的网络传输。应用程序软件，即牙体模型数据的显示和测量，是与UNISN公司合作，在Microsoft Windows系统上新开发的，涉及三个-牙科模型的尺寸数据。
