Which imaging modality provides the most accurate assessment of bone around dental implants beyond two-dimensional imaging?

• A. Panoramic Radiography
• B. Periapical Radiographs
• C. Cone-Beam Computed Tomography (CBCT)
• D. Conventional CT

Answer: (C)

Three-dimensional assessment is essential when evaluating bone around dental implants because it reveals dimensions and defects that two-dimensional images miss. Panoramic and periapical radiographs flatten anatomy and suffer distortion and overlapping structures, so they can’t reliably show buccal–lingual bone thickness, hidden peri-implant defects, or precise spatial relationships with neighboring structures. Cone-beam CT provides isotropic voxels and multiplanar views (axial, sagittal, coronal), letting you measure bone height and width around the implant, detect dehiscence or fenestration, and assess proximity to critical anatomy in all directions. Compared with conventional CT, CBCT offers similar diagnostic detail with much lower radiation dose and is tailored for dental applications, making it the most accurate choice for evaluating bone around implants beyond 2D imaging.
