Manufacturing method for artificial skull repair prosthesis

Abstract

The invention discloses a manufacturing method for an artificial skull repair prosthesis by the adoption of the 3D printing technology. The method is used for manufacturing the artificial skull repair prosthesis which is attractive in appearance, good in anastomosis and few in complication for skull-defect patients. The manufacturing method for the artificial skull repair prosthesis has the advantages that according to the manufacturing method, the skull is manually manufactured by the adoption of the 3D printing technology to repair and rebuild the skull of a patient, so that the defects, in molding, strength, process, anastomosis and the like, of common skull repair materials are overcome, the manufacturing cycle is greatly shortened, and the side effects of clinical application are remarkably reduced.

Description

technical field [0001] The invention relates to a method for preparing an artificial skull repair prosthesis, in particular to the production of a 3D printed skull defect shaping reconstruction prosthesis. Background technique [0002] Due to various reasons such as wars, car accidents, and heavy objects, many patients have skull defects due to surgery or skull injuries. After some patients are in stable condition, the skull defect affects beauty, and the defect is not protected by the skull, which poses a safety hazard. With the improvement of living standards, not only from the perspective of safety, but also from the perspective of quality of life, many patients require the repair of skull defects. For the purposes of beauty, brain safety, etc., it is accompanied by cranioplasty. Therefore, there are huge potential users in the application of the research results, and the market application prospect is broad. [0003] In the manufacturing process, there are mainly four...

Moreover, the existence of metal substances has psychological barriers and affects further imaging examinations such as MRI (MRI has magnetism, which has disadvantages for defective metal reconstruction materials). These shortcomings are difficult to overcome in titanium mesh skull repair, which seriously affects the repair. Effect

Casting and mold pressing have improved the quality of the prosthetic prosthesis, but the manufacturing cycle is long, the cost is high and the flexibility is poor. It is difficult to guarantee the completion of debridement and repair in one operation with the current preparation methods

Indentation, wrinkling, springback and edge warping are unique forming defects in multi-point forming. Indentation and wrinkling affect the appearance of cranial prosthesis, and springback will make the size of the prosthesis inconsistent with the size of the bone window. Causing the prosthesis to collapse or become loose

Edge warping will make the prosthesis and bone window not fit well, affecting the quality of the restoration
