Which extraoral radiographic view is used to evaluate bone height, width, and quality for implants?

• A. Cephalometric
• B. Lateral oblique
• C. Panoramic
• D. Tomographic

Answer: (D)

To plan implants you need cross‑sectional information about the jawbone that shows exact dimensions and density. Tomographic imaging provides sectional views of the jaw, allowing precise measurement of vertical bone height, buccolingual (width) thickness, and the quality of the bone (cortical vs. cancellous patterns). This level of detail is essential for determining if there is enough bone to place an implant safely and predictably, and for avoiding nearby structures.

Panoramic radiographs can reveal the general anatomy but have magnification and distortion and don’t reliably show true width or bone density at a specific site. Cephalometric radiographs are used for skeletal relationships, not local implant planning. Lateral oblique views offer limited cross‑sectional detail. In contrast, tomographic views (including cone‑beam CT) deliver the cross‑sectional information that directly addresses height, width, and quality for implants.
