A rectangular artificial tooth root placed in the jawbone to support a prosthesis?

• A. Impression tray
• B. Desensitizer
• C. Alginate
• D. Implant

Answer: (D)

The concept being tested is identifying the device that replaces a tooth root by anchoring into the jawbone to support a prosthetic tooth. That device is a dental implant. It is surgically placed into the jawbone and, once integrated with the bone (osseointegration), provides a stable foundation for crowns, bridges, or dentures. This sets it apart from other items like an impression tray (used to hold impression material), alginate (an impression material), or a desensitizer (used to reduce tooth sensitivity). Implants are designed to mimic natural root function and offer long-term support for prostheses.
