Method for manufacturing biomedical glass ceramic material

Abstract

The invention relates to a method for manufacturing a biomedical glass ceramic material, a calcium phosphate system ceramic raw material and nano-level titanium dioxide powder are firstly prepared, the nano-level titanium dioxide powder must contain a preset proportion of titanium dioxide anatase type crystal structure, and then the calcium phosphate system ceramic raw material and the nano-leveltitanium dioxide powder are mixed according to a preset proportion, thereby manufacturing a mixed raw material. Then, the mixed raw material is melted and quenched, thereby forming biomedical glass. Finally, the biomedical glass is ground into biomedical glass powder, and thermal treatment is further carried out for recrystallizing the biomedical glass powder, thereby forming the biomedical glassceramic material. The biomedical glass ceramic material can be further polarized for forming a biomedical charged glass ceramic material, thereby being implanted in human body for inducing bone growth in clinical applications.

Description

technical field [0001] The present invention relates to a kind of manufacturing method of biomedical (biomedical) glass-ceramic material, relate in particular to a kind of use monocalcium phosphate series ceramic raw material and a nano-scale titanium dioxide powder rich in titanium dioxide anatase type (anatase phase) crystal structure to make biomedical A method for medical glass-ceramic material, and the biomedical glass-ceramic material can be further polarized to form a biomedical charged glass-ceramic material. Background technique [0002] In the human body, the bones that support the head, torso, and limbs are mainly composed of bone tissue and bone growth cells. Among them, the main components of bone tissue are calcium phosphate-based compounds. In real life, some bones may have congenital defects, and human body functions may decline with age, resulting in bone aging and defects. People can be engaged in various jobs for many years, but it may also cause mechani...

AI Technical Summary

Problems solved by technology

Although these calcium phosphate materials have the advantages of ceramic properties and good biocompatibility; however, these materials generally have two shortcomings that are difficult to improve

First, these materials are often limited in practical application due to their insufficient mechanical strength. Generally speaking, most of them can only be used in orthopedics and dentistry as replacement materials that only need to withstand small stress loads

Second, when these materials are implanted into the human body, they lack the function of inducing bone growth, resulting in slower bone regeneration and longer recovery times for patients

[0018] In view of the above, in the prior art, there are generally problems of insufficient mechanical strength, which lead to many limitations in practical application; and the lack of the function of inducing bone growth, resulting in longer recovery time for patients, etc.
