What distinguishes an osteotome from a chisel?

• A. Osteotome is sharp on one side
• B. Chisel is shaped like a steeple
• C. Osteotome is sharp on both sides
• D. Chisel has an angled side and is sharp on both sides

Answer: (C)

The distinction between an osteotome and a chisel primarily lies in their design and cutting edges. An osteotome is specifically crafted with a sharp edge that is typically present on one side, allowing it to make clean cuts in bone without the need for a secondary cutting edge. This characteristic is particularly advantageous when performing delicate surgical procedures on bony structures, as it minimizes the risk of fractures or unwanted damage to surrounding tissues.

In contrast, a chisel is designed with a more robust shape and is often sharper on both sides, providing the versatility to cut through materials more aggressively. The angled edge of a chisel gives it the capability to remove material with more force or to perform different types of cuts depending on the angle of application.

Therefore, the understanding of an osteotome being sharp on both sides is not accurate in the context of its defined role and function, which is why that choice clearly supports the relationship and distinction between these two surgical instruments. This specificity in design makes the osteotome a vital tool in orthopedic and craniofacial surgeries where precision and control are paramount.
