Title:
DIGITAL ABUTMENT AND METHOD FOR MANUFACTURING DENTAL RESTORATIVE MATERIAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/197133
Kind Code:
A1
Abstract:
In order to improve the convenience of procedures and scan recognition rates, a method for manufacturing a dental restorative material using a digital abutment is provided in the present invention, the method including: a first step in which a target dental arch having a digital abutment inserted therein is scanned through an intraoral scanner, a unique identification marking for scan image processing recognition being formed on an upper part of the digital abutment; a second step in which the digital abutment, scanned through the intraoral scanner, and surface information about the target dental arch are acquired by being converted into three-dimensional digital data through scan image processing, and a three-dimensional work image that includes surface information about the digital abutment converted to three-dimensional digital data is generated; a third step in which a virtual abutment extracted from a digital library in correspondence to the unique identification marking of the digital abutment is virtually arrayed and replaced in the three-dimensional work image, and design information is generated of an artificial crown in which a virtual matching groove corresponding to the outer profile of the virtual abutment is set; and a fourth step in which the artificial crown is finally manufactured to correspond to the design information.
