Which instrument is a Couplands Chisel?

• A. Warwick James Elevator
• B. Couplands Chisel
• C. Scalpel
• D. Dissecting Forceps

Answer: (B)

Understanding instrument types and their uses in oral surgery helps you match names to their functions. A chisel is designed to cut or shape hard tissue, typically bone, and is used with a mallet or hammer to reshape or remove bone as needed. The Coupland’s chisel is one such bone-cutting instrument, named for its designer, and it is specifically a chisel.

This is why it fits the question: the instrument that is a Coupland’s chisel is the one whose purpose and design are built for cutting bone, not soft tissue or grasping tissue. In contrast, a scalpel is for soft-tissue incisions, dissecting forceps are for grasping and handling tissue, and a Warwick James elevator is used to reflect or separate tissues.
