According to the current status of related medical materials issued by the Food and Drug Administration of the Ministry of Health and Welfare, bone-bulging medical materials can be divided into five categories, of which the latter two are used most frequently: autologous bone demineralized bone Biological Bone Sintering synthetic artificial bone bone cement Among all the bone supplement medical materials, the quality of autologous bone is the most limited, mainly because it is taken out from the patient's bone tissue during surgery and filled to the defect site.
Common bone extraction ranges include tibia, fibula, Photo Manipulation Services ribs, and iliac bones. The advantage is that there is no problem of immune rejection. In addition, demineralized bone is a human bone provided by donations. After screening, the bone matrix left by minerals is removed to become an allograft product of demineralized bone matrix (DBM), because it contains the conduction required for human bone formation. Factors, which can induce osteogenesis, are the best choice for repair other than autologous bone. There is also a kind of biological bone sintering, which is mainly obtained by removing adipose tissue and protein from bone tissue (such as pig bone and bovine bone) provided by different species, and then sintering at high temperature.
The advantage is that it is similar to the human bone tissue structure, and the cell generation environment is better, which can promote the proliferation of hard bone cells, but a few people will experience immune rejection. The most common is synthetic artificial bone, the main material is calcium phosphate salts (such as tricalcium phosphate, hydroxyapatite), which is also the most widely used bone filling material, because the composition is similar to human bone, and it is made of Porous to mimic natural bone properties, it can provide osteoconductive function and serve as an attachment scaffold for bone cells to grow. As for bone cement, it is a product made of acrylic material "polymethyl methacrylate" (PMMA).
