项目摘要

We already developed the digitizing system for the dentition study model using a line laser and CCD camera, which was available for measuring the distance of anatomical characteristic points on the computer graphics optionally and could focus the scanning area to progress the measuring accuracy and release data for a part of the dental CAD/CAM system. However, the released data was only available for the design of crowns, and not available for digitizing the under cut area of alveolar ridge, proximal area, and etc. Therefore, we have developed another prototype system, equipping two line lasers, one CCD camera, and additional axis drive of working stage. We already found this prototype could not lose any data for a dentition model. Moreover, since this system was available for digitizing the optionally small area like an inlay restoration model, in this study, we developed automatically superimposing software for dental education and evaluated the conformity of different preparation models between the master model and the student prepared model.Newly developed digitizing software was available to reproduce the dentition study models and automatically superimpose the two kinds of different data to evaluate the dental preparation practice. Other systems developed by other institutions were necessary to keep the axis of coordinates using a fixing jig before digitizing the model. However, using this software, three-dimensional form of each model was recognized and superimposed automatically without influenced by the axis of coordinates. Therefore, the present software was able to reduce the restrictions at the time of model digitizing.

我们已经开发了牙列研究模型的数字化系统，该系统使用线激光和CCD摄像机，可以在计算机图形上任意测量解剖特征点的距离，并可以对扫描区域进行聚焦，提高测量精度，发布部分牙科CAD/CAM系统的数据。然而，所公布的数据仅适用于牙冠的设计，而不能用于数字化牙槽骨下切区、近牙区等。因此，我们开发了另一套原型系统，配备了两台线激光器、一台CCD摄像机和附加的工作台轴驱动装置。我们已经发现这个原型不会丢失牙列模型的任何数据。此外，由于该系统适用于像嵌体修复模型这样的可选小区域的数字化，在本研究中，我们开发了用于牙科教育的自动叠加软件，并评估了不同预备模型在主模型和学生预备模型之间的一致性；新开发的数字化软件可用于再现牙列研究模型，并自动叠加两种不同的数据来评价牙科预备实践。其他机构开发的其他系统也是必要的，以便在数字化模型之前使用固定夹具保持坐标轴。但是，使用该软件可以自动识别和叠加每个模型的三维形状，而不受坐标轴的影响。因此，本软件能够减少模型数字化时的限制。
