HOSA Chairside Assisting & Dental Instruments Practice Test 2026 – Complete Exam Prep

The correct choice is a chisel, as it is specifically designed for the removal of bone and works effectively when combined with a mallet. The chisel's sharp edge allows for precise cutting and sculpting of bone tissue. When used in conjunction with a mallet, the force applied with the mallet helps drive the chisel through the bone, making the procedure more efficient and manageable.

Rongeurs, while also used in surgical procedures, are designed for grasping and cutting soft tissue or removing small pieces of bone, rather than the precise bone shaping that a chisel provides. The mallet is only a tool that aids the chisel in its function but is not the main instrument used for bone removal. Sutures are unrelated to the process of bone removal, as they are used for closing incisions and securing tissue together after surgical procedures. Thus, the chisel is the best choice for this task.
