Bioglass / polyether-ether-ketone composite materials, method for preparing same, application thereof, bone repair body and bone repair body preparation method

Abstract

The invention discloses bioglass / polyether-ether-ketone composite materials, a method for preparing the bioglass / polyether-ether-ketone composite materials, the application of the bioglass / polyether-ether-ketone composite materials, a bone repair body and a bone repair body preparation method. The composite material preparation method comprises the steps that 20-40wt% of 5-20-micron bioglass powder and 60-80wt% 10-20-micron polyether-ether-ketone powder are evenly mixed to obtain mixed powder; the mixed powder is processed and formed, and accordingly the composite materials are prepared. The composite materials have good biological activity and biocompatibility, the composite materials and bone tissues have good mechanical compatibility, and the composite materials can stimulate bone growth, accelerate bone cure, reduce cure time after bone repair materials are implanted, and have bacterium resistance performance. The preparation techniques of the composite materials can be adjusted according to clinic requirements to prepare bone repair bodies of different shapes, difference specifications and different mechanical properties. The bone repair body will not cause inflammatory responses after being implanted, the mechanical property of the bone repair body is matched with human bones, the negative effects that the bone repair materials loosen and bone resorption happens will not be caused, and the bone repair body can meet requirements of clinic for bone repair.

Description

technical field

[0001] The invention relates to the field of polyether ether ketone composite materials, in particular to a bioglass / polyether ether ketone composite material and its preparation method and application, and in particular to a bone restoration and its preparation method. Background technique

[0002] Modern bone implant materials are increasingly emphasizing the biological functions of implants, and the concept of osseointegration has been widely used in the evaluation of bone implants. At present, titanium-based and ceramic bone implant materials widely used in clinical practice still have their own shortcomings that are difficult to overcome. Bioactive glass (BG) has a history of 40 years since Hench invented it in 1971. It is mainly used as a bone substitute and has been used clinically for nearly 30 years with good results. BG has good biocompatibility and bioactivity, and has been recognized as a suitable permanent implant material all over the world. B...
