20100055647Manufacturing Method and Apparatus of Artificial Teeth Using Dental CT - The present invention discloses a manufacturing method and apparatus of artificial human teeth using dental CT. The method comprises the steps of: removing a damaged part of human teeth; obtaining surface coordinates of the teeth using a dental CT machine located at a dental clinic for a medical checkup; converting the surface coordinates of the actual teeth to CAD/CAM data; manufacturing artificial teeth by cutting metal or ceramic with a three-dimensional N/C machine using the converted data; obtaining shape data of upper or lower actual teeth corresponding to the artificial teeth; changing the shape of the artificial teeth by direct surface processing according to the shape data of the upper or lower teeth; and coating ceramic to the artificial teeth after sintering the processed artificial teeth for a predetermined period.03-04-2010
20090245461COMPLEX IMAGING SYSTEM FOR DENTAL - Disclosed therein is a dental complex imaging system including: a base seated on the ground; a chair part disposed on the upper portion of the base for allowing a patient to wait for imaging with him/her seated thereon; a pole mounted on the base so as to be adjacent to the chair part; a support part adapted to extend toward the patient from the top of the pole; an expanding and contracting part pivotally coupled to the underside of the support part so as to be expanded and contracted; a radiation generator part disposed below one side of the expanding and contracting part and moving according to expansion and contraction of the expanding and contracting part for emitting radiation selected according to CT imaging, cephalography and panoramic radiography; a radiation detecting part disposed on the other side of the expanding and contracting part in such a way as to be opposed to the radiation generator part for detecting radiation selectively emitted from the radiation generator part according to the CT imaging, the cephalography and the panoramic radiography; and a control part for reading imaging information detected by the radiation detecting part. The dental complex imaging system can provide a doctor and a patient with convenience and economic profits since it does not need various equipments for conducting the CT imaging, the panoramic radiography, and the cephalography.10-01-2009
