Development of the uniform management system for the digital dental data

自2014年4月起，CAD/CAM系统已在一般保险业务中采用。数字数据的统一管理，成为本研究的目的，已成为一项紧迫的任务。在第一年，我们制作了小型口腔内扫描仪的样机，并对其准确性进行了研究。这些数字化设备需要模型的复制方法来解释治疗或实验室工作的流程。然后，我们调查了工业领域中使用的各种快速原型系统的重现性。此外，我们使用市售的口腔内扫描仪检查了技术水平对修复产品重复性的影响。

CAD / CAM system has been adopted in the general insurance practice from April 2014. Uniform management of digital data, purpose of this study, has become an urgent task. At the first year, we prototyped small size intra oral scanner and investigated the accuracy. These digitizing devices is required the reproduction method of the model to explain the flow of treatment or laboratory work.Then, we investigate the reproducibility of the various rapid prototyping systems used in the industry field. Furthermore, we examined the effect of the skill level to the reproducibility of the restoration products using intra oral scanner commercially available.
