UMD: Metallic sheets designed to repair small cranial bone defects (i.e., cranioplasty) intraoperatively. These materials usually consist of an inert, malleable metal (typically tantalum) perforated sheet that can be shaped to the desired contour using a mallet and a wood block and cut with shears to the appropriate dimension. Prefabricated metallic plates, which may be manufactured from metallic sheets, are frequently used to repair larger cranial bone defects.
