Abstract
The present invention provides a digital dental prosthesis manufacturing method including a first step in which a three-dimensional work image is acquired, the three-dimensional work image including surface information on an inner side of an oral cavity and a target dental arch in which fixtures are placed and occlusion information between the target dental arch and an opposing dental arch; a second step in which a temporary digital dental prosthesis is designed and manufactured; a third step in which the manufactured temporary digital dental prosthesis is installed on the target dental arch; and a fourth step in which a virtual coupling groove, which corresponds to surface information on the corrected coupling region, is set in an inner surface profile, which is set according to surface information on the corrected temporary shape-matching surface that is included in the corrected scan image, and a final digital dental prosthesis is designed and manufactured.
