Which radiographic technique is preferred for evaluating dental implants' osseointegration?

• A. Panoramic radiography.
• B. Occlusal radiographs.
• C. Periapical radiographs using a parallel technique.
• D. CBCT.

Answer: (D)

Evaluating how the bone surrounds an implant in three dimensions is essential to assessing osseointegration. Cone beam computed tomography provides volumetric, high-resolution images that let you inspect the bone-implant interface in all directions, measure peri-implant bone height and width, and detect defects or bone remodeling that might be hidden on 2D views due to superimposition. This 3D view makes it possible to identify subtle changes around the implant, such as buccal–lingual bone loss, dehiscences, or fenestrations, and to evaluate proximity to adjacent structures. In contrast, panoramic radiographs flatten the anatomy and distort relationships; periapical radiographs with a parallel technique, while good for a sharp view of a single plane, still provide only a two-dimensional snapshot and can miss changes out of that plane; occlusal radiographs offer limited scope and resolution for the implant-bone interface. Because osseointegration involves the complex spatial relationship between implant surface and surrounding bone, the three-dimensional assessment that CBCT provides is the most informative option for evaluating implant integration and planning any further treatment.
