Final answer:
A bone file or rasp is used to smooth the surface of bones in medical procedures after most of the undesirable bone has been removed during bone remodeling.
Step-by-step explanation:
The instrument used to smooth the surface of the bone after most of the undesirable bone has been removed is known as a bone file or rasp. In the process of bone remodeling, after a fracture or during regular maintenance, osteoclasts resorb excess bone, and osteoblasts deposit new bone to replace that which is resorbed.
This ensures that the bone maintains a structure that is as close to the original, unbroken state as possible. Over time, compact bone is added to create strong, functional bone tissue.
The instrument used to smooth the surface of the bone after most of the undesirable bone has been removed is called a bone file. A bone file is a hand tool that has a roughened surface with small ridges or teeth, which helps to remove any remaining uneven areas on the bone surface.
For example, after a bone fracture, a surgeon may use a bone file to smooth the edges of the fractured bone so that they can fit together properly during the healing process.
