Which imaging modality can provide 3D evaluation of dental implants' osseointegration when needed?

• A. Intraoral bitewing radiography.
• B. Periapical radiography.
• C. CBCT.
• D. Panoramic radiography.

Answer: (C)

Understanding how the bone surrounds an implant in three dimensions is essential when evaluating osseointegration. Cone-beam computed tomography provides a volumetric dataset that can be explored in axial, sagittal, and coronal planes, giving you true 3D visualization of the peri-implant bone. This lets you assess bone height and thickness around the implant, buccal–lingual bone, and any defects such as dehiscences or fenestrations, as well as the spatial relationship to nearby anatomy. While 2D radiographs look at structures flat and can miss or distort features due to overlap, CBCT renders the area in 3D and reduces ambiguity. Therefore, when a 3D assessment of implant integration is needed, CBCT is the best choice.
