生体材料の医学的応用とその現状

概要

論文の詳細を見る
Through long-term studies and progress in the engineering field, various biomaterials have been developed and put to excellent practical use in the medical field, bringing much benefit to human recipients. However, there are many inorganic materials and products being tried that are incompatible with the organic constituents of the human body. Unexpected tissue reactions sometimes follow the introduction of these materials into the body. Therefore, the development of new biomaterials is critical to improvements in patient care. Advances in the development of useful biomaterials requires engineers who understand the mechanisms of tissue reaction as well as medical investigators who understand the properties of these materials and can conceive of medical applications for such products.<BR>In the field of orthopaedic surgery, in particular, metal alloys, high molecular-weight substances, and ceramics have been used in artificial joints, fracture fixations, and others. There has been a recent rise in applications of titanium, high density polyethylene, and hydroxyapatite.
