Document Type and Number:
WIPO Patent Application WO/2022/203128
Kind Code:
A1
Abstract:
In order to improve precision and aesthetics, the present invention provides a method for manufacturing a digital dental prosthesis comprising: a first step for generating a planning image; a second step for re-setting, as three-dimensional surface information of a virtual correction base that includes a preset first shrinkage tolerance and is expanded toward the outside, three-dimensional surface information of a virtual dental prosthesis base on which a virtual artificial tooth part that matches surface information of an opposing dental arch so as to occlude therewith is arranged and of which an inner surface portion is set on the basis of the surface information of a target arch; a third step for transmitting the three-dimensional surface information of the virtual correction base to a manufacturing apparatus so as to form, as a real product, a preliminary base made of a zirconia material, wherein a dental prosthesis base that is contracted to a volume corresponding to the virtual dental prosthesis base is manufactured by plastic processing of the preliminary base; and a fourth step for manufacturing a final digital dental prosthesis.
