Component parts of the osteotome, and the instrument in use. An osteotome is an instrument used for cutting or preparing bone. Osteotomes are similar to a chisel but bevelled on both sides. They are used today in plastic surgery, orthopedic surgery and dental implantation. The chain osteotome, originally referred to simply as the osteotome, was invented by the German physician Bernhard Heine in 1830. This device is essentially a small chainsaw.
os'teÂ·oÂ·clas'tic adj. osteoclast. A specialized bone cell that absorbs bone, allowing for the deposition of new bone and maintenance of bone strength. Osteoclasts secrete enyzmes that dissolve the matrix of old bone tissue and acids that dissolve bone salts, which contain calcium and phosphorus. Except in growing bone, the rate of bone deposition and bone absorption equal each other so that bone mass remains constant. A mass of osteoclasts absorbs bone from the outer surfaces inward for about three weeks.
