Title:
CUSTOMIZED MULTI-HOLE DENTAL BRIDGE BASED ON ADDITIVE OR SUBTRACTIVE PROCESSING MODE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/056367
Kind Code:
A1
Abstract:
A customized multi-hole dental bridge based on an additive or subtractive processing mode and a manufacturing method therefor. The manufacturing method comprises the steps of: 1) obtaining an oral environment model and a scan post model to obtain implant site connector data; 2) making a dental bridge STL digital model; 3) forming multiple holes in the dental bridge STL digital model; 4) converting the dental bridge STL digital model obtained in step 3 and outputting same as an STP solid model; 5) performing finite element analysis on the STP solid model; 6) molding the STP solid model in step 5 by means of metal 3D printing to obtain a semi-finished dental bridge product; and 7) performing precision machining on an end face and an inner taper hole of an implant site connector of the semi-finished dental bridge product by using a CNC machine tool, and then removing a positioning support rod to obtain a customized multi-hole dental bridge. Additive or subtractive manufacturing of a dental bridge is implemented by means of metal 3D printing and CNC cutting, so that the dental bridge effectively reduces the elastic modulus thereof while meeting the strength requirements, and also implements the high precision machining of the implant site connector of the dental bridge.
