A standard CT scan may be used to determine size and placement location for implants.

• A. A standard CT scan cannot be used for implant planning.
• B. A standard CT scan may be used to determine size and placement location for implants.
• C. A standard CT scan is only used for root canal analysis.
• D. A standard CT scan is performed without the patient lying down.

Answer: (B)

Computed tomography provides a 3D view of the jaw, allowing precise measurement of bone height, width, and density, as well as the location of important structures like the inferior alveolar canal and the maxillary sinus. This information is essential for implant planning because it guides the choice of implant size—length and diameter—and the exact placement angle and position to maximize stability and avoid complications. The data from a CT scan also helps determine whether bone grafting or sinus augmentation might be needed before placing an implant. Because of these capabilities, a standard CT scan is well suited to determine both the size and placement location for implants.

It’s not limited to root canal analysis, and while patient positioning can vary with equipment, the essential point is that CT imaging provides the detailed anatomical and dimensional information necessary for implant planning, not a restriction on how the patient is positioned.
