Which instrument is a bone ronguer?

• A. Warwick James Elevator
• B. Bone Ronguers
• C. Couplands Chisel
• D. Rake Retractor

Answer: (B)

Bone rongeurs are the tools specifically designed to cut and shape bone. They work like sturdy pliers with sharp, beaked jaws that bite into hard tissue, allowing precise removal or contouring of bone in the jaw, around tooth sockets, or at implant sites. This focus on hard tissue trimming distinguishes them from the other instruments listed: an elevator loosens and elevates teeth or soft tissues, a chisel removes or sections bone with a hammer blow, and a rake retractor holds back soft tissue to improve visibility. In this context, the instrument whose primary function is cutting and trimming bone is the bone rongeur.
