When planning implant placement, which imaging modality provides the most comprehensive assessment of bone quality and quantity?

• A. CBCT, often with bone density assessment.
• B. Panoramic radiography.
• C. Intraoral periapical radiographs.
• D. MRI.

Answer: (A)

For implant planning, you need imaging that shows bone in three dimensions so you can judge both how much bone is there and how solid it is. Cone-beam computed tomography provides a true 3D view of the alveolar bone, letting you measure bone height and width accurately, assess cortical bone thickness and trabecular pattern, and see the exact spatial relationship to important structures like nerves or sinuses. This 3D detail is what makes it far more reliable than 2D panoramics or intraoral periapicals, which can distort or miss the true bone volume and don’t reliably show buccolingual width. MRI can image soft tissues and bone marrow, but it’s not well suited for evaluating cortical bone quantity and density for implant planning and isn’t the standard tool for this purpose. When available, CBCT data can be paired with bone density assessment to give a density estimate, though the exact values depend on the machine and calibration. The important idea is that CBCT offers the most complete view of bone quality and quantity for planning implants.
