摘要： Provided is a table for three-dimensional (3D)-scanning of a dental model, and more particularly, a table for 3D-scanning of a dental mode, for simultaneously 3D-scanning a dental model while placing a maxillary dental model, a mandibular dental model, and a partial dental model separated therefrom at the same time. The table includes a first arrangement portion for placing a maxillary dental model thereon, a second arrangement portion for a mandibular dental model thereon, and a third arrangement portion disposed between the first arrangement portion and the second arrangement portion and for placing thereon a partial dental model separated from the maxillary dental model or the mandibular dental model.

摘要： In a desktop three-dimensional scanner for dental use of the related art, a two-axis rotation motion unit, on which a target object can be placed and rotated in order to image the entire shape of the target object, is coupled to the scanner, and thus, when a subject is placed on the imaging stage and is rotated along the horizontal axis of rotation of the stage, the subject is dropped from the stage by gravity after being inclined, and accordingly, additional fixing means or a receiving jig should be placed on the stage together with the subject to prevent same. In such a case, inconvenience is caused because the target objects to be scanned have various shapes and the fixing means or receiving jigs should fit the shapes thereof. According to one embodiment of the desktop three-dimensional scanner for dental user of the present invention, a camera and a projector are provided on the unit for changing the horizontal axis of rotation of the imaging stage, and thus a target object does not have to be inclined during the scanning process and dental prostheses of various shapes can be three-dimensionally scanned even without additional fixing means or a receiving jig.
摘要翻译：在牙科用现有技术的桌面三维扫描仪，两轴的旋转运动单元，在其上的目标对象可以在顺序放置并旋转以图像目标物体的整体形状，被耦合到扫描仪，因而，当对象被放置在成像级和沿平台旋转的水平轴旋转时，所述对象被从阶段通过重力倾斜后下降，并且相应地，额外的固定装置或接收夹具shoulderstand 要在舞台上与主题放在一起，以防止同样的。在求的情况下，造成不便，因为被扫描的对象物具有各种形状和固定装置或接收夹具shoulderstand适合其形状。。根据本发明的牙科用用户桌面三维扫描仪的一个实施例，提供了单元上的照相机和投影仪，用于改变所述成像台的旋转的水平轴线，并且因此目标对象不必在扫描过程中与各种形状的假牙倾斜可以是三维扫描，即使没有额外的固定装置或接收夹具。
