Problems solved by technology

[0003] Nowadays, titanium mesh is commonly used to make skull repair prosthesis in medicine. Although titanium mesh has the characteristics of good tissue compatibility, its strength and hardness are lower than that of skull tissue, and plastic deformation occurs when it is resistant to impact. The sharp edge of titanium mesh is easy to pierce the skin and cause damage. exposed, causing skin infection
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
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

Embodiment Construction

[0017] A method for preparing an artificial skull repair prosthesis, comprising the steps of:

[0018] (1) Using imaging techniques such as CT or MRI, establish a three-dimensional model of the skull repair prosthesis in three-dimensional modeling software;

[0019] (2) According to the data of the three-dimensional model of the prosthesis, 3D printing technology is used to make a skull defect mold;

[0020] (3) The material used for the prosthesis is a material with excellent tissue compatibility with human beings (such as HAP bone cement material and citric acid aqueous solution to form a water and coagulation system);

[0021] (4) Through computer calculation, calculate the volume and other parameters of the required filling prosthesis, and deploy the filling material, so that it is filled into the mold and pressed to achieve the required prosthesis for repairing the skull defect;

[0022] (5) Clean up the printed prosthesis materials and improve individualized shaping.

Abstract

The invention discloses a method for manufacturing an artificial skull restoration prosthesis through the 3D printing technology and other technologies. The method is used for manufacturing the artificial skull restoration prosthesis which is beautiful in appearance, is good in matching performance, causes few complications for skull defect patients. The method is characterized by artificially manufacturing the skull by comprehensively using the 3D printing technology and other technologies to achieve restoration and reconstruction of the skull of the patient, overcomes the defects of common skull restoration materials on the aspects of molding, strength, process, matching performance and the like, and obviously reduces side effects in clinical application.

Description

technical field [0001] The invention relates to a method for preparing an artificial skull repair prosthesis, in particular to 3D printing to make a skull defect mold, and finally realizes the production of a plastic and reconstructed skull prosthesis. Background technique [0002] Various reasons, such as wars, car accidents, heavy objects, etc., have caused many patients to have skull defects due to surgery or skull injuries. There are potential safety hazards. With the improvement of living standards, many patients require the repair of skull defects from the perspective of safety and quality of life. Therefore, there are huge potential users in the application of the research results, and the market application prospect is broad. [0003] Nowadays, titanium mesh is commonly used to make skull repair prosthesis in medicine. Although titanium mesh has the characteristics of good tissue compatibility, its strength and hardness are lower than that of skull tissue, and plast...
