Title:
3D PRINTING METHOD FOR DENTAL IMPLANT ABUTMENT
Document Type and Number:
WIPO Patent Application WO/2019/095660
Kind Code:
A1
Abstract:
A 3D printing method for a dental implant abutment, the method comprising three-dimensional scanning, three-dimensional designing, data processing, 3D printing, and component post-processing. The method is characterized in that: for the three-dimensional scanning, overall profiles of a three-dimensional model are first obtained by means of blue-light scanning, and then fine scanning of an interface portion of the implant abutment is performed by means of probe-based scanning; burr compensation is not included in the three-dimensional design, and for data processing, smooth surface structures free of additional support members are provided at the interface where the dental implant abutment is connected to an implant, at the interior of the interface, and at the periphery of the interface. The 3D printing method for a dental implant abutment significantly improves the molding precision of the dental implant abutment, enables the implant abutment to better meet detail requirements, and simplifies a molding process of selective laser melting, thereby greatly shortening the production period for implant abutments and improving molding efficiency.
