Explanation
The utility model relates to a bone repair materials which is used to fill the gap or bone cavity between bone and implant and has the characteristics of self coagulation. PMMA bone cemem consists of two phases: powder and liquid. The powder is mainly polymethyl methacrylate powder and a small amount of initiator (peroxide, such as benzoyl peroxide). The liquid agent is mainly methyl methacrylate monomer and appropriate accelerator. After the two components are mixed in proper proportion, they polymerization and curing within 5-10mm. Therefore, in recent years, researchers have continuously improved PMMA bone cemem. At the same time, some bioactive bone cement with good biocompatibility, less heat release during curing and similar composition to human hard tissues have been developed.
