A method for manufacturing a dental prosthesis is disclosed. The method includes a first step of photographing a patient's mouth with a dental cone beam CT, a second step of converting CT data photographed at the first step into a CAD file, a third step of designing a shape of the dental prosthesis with the CAD file using CAD software, a fourth step of correcting the shape of the designed prosthesis using occlusion simulation software, a fifth step of converting the shape of the prosthesis which is designed finally into manufacturing data, and a sixth step of transmitting the manufacturing data to a dental prosthesis manufacturing machine, thus manufacturing the dental prosthesis.

The present invention relates to a recording medium a method and an apparatus for generating virtual teeth and recording media storing a program performing the method. According to an embodiment of the present invention, a method for generating virtual teeth includes (a) acquiring a tooth image having three-dimensional information from teeth including a damaged tooth; (b) determining an image of a virtual tooth to be inserted into a position of the damaged tooth in a tooth image library having predetermined three-dimensional information and inserting the determined virtual tooth image into the acquired tooth image; and (c) modifying the virtual tooth image by considering tooth images positioned at upper and lower sides or right and left sides of the virtual tooth image. According to the embodiment of the present invention, it is possible to produce a prosthesis most suitable for the state of patient's teeth only once and an operator can minimize post-processing of the produced prosthesis. Further, a patient can minimize a clinic time and decrease the number of times of hospital visits.
