Manufacturing method of individualized prosthesis with porous structure

Abstract

The invention discloses a manufacturing method of an individualized prosthesis with a porous structure. The method comprises the steps of extracting CT data; reversely modeling; forward designing; adding supports and cutting into slices: importing an acquired design model into Materialise Magics software to add the supports and cut into slices; importing sliced data into RPPPath software to plan a scanning path and importing into selective laser melting molding equipment for molding; and post-processing: post-processing molded prosthesis components for a part to be repaired, so as to finally acquire the individualized titanium alloy prosthesis with the porous structure for the part to be repaired. A selective laser melting molding technology is used for manufacturing, relatively high individualization is achieved, and a face form of a patient can be well recovered; the method provided by the invention adopts a microcosmic porous structure with suitable porous parameters, so that synostosis is facilitated; the method is high in practicability instead of staying in a model level, and relative design content is applicable to different cases and different cut bone forms.

Description

technical field [0001] The invention relates to the field of prosthesis preparation, in particular to a method for manufacturing a prosthesis with a personalized porous structure. Background technique [0002] With the development of scientific and medical technology, complex operations such as mandibular defect and missing repair have also gradually improved. At present, mandibular repair is mostly used to intercept human autogenous bone (such as fibula) and connect it with the healthy jaw parts at both ends under the fixation of prefabricated titanium plate and titanium nail. Although this method is not easy to reject and can achieve good osseointegration, but the bone resources are limited, it will cause damage to the bone harvesting site, and the external shape is not easy to restore. [0003] In recent years, scholars have found that some porous metal materials such as porous titanium and porous nickel-titanium are ideal substitutes for human bones. The porous structur...
