Which type of x-ray is NOT recommended during an implant procedure?

The bite-wing x-ray is typically not recommended during an implant procedure because it primarily focuses on capturing the details of the crowns of posterior teeth and the interproximal spaces, which may not provide the necessary information about the surrounding bone structure and the precise location for implant placement.

In contrast, panoramic x-rays are useful because they provide a broad view of the entire dental arch and surrounding structures, which is valuable for assessing the overall anatomy and planning for implant placement. Periapical x-rays are often used to focus on specific teeth and surrounding bone, providing detailed images that assist in evaluating the site for an implant. Occlusal x-rays also serve a different purpose by providing views of the occlusal surfaces and can help in assessing the space available for an implant.

Thus, while bite-wing x-rays are excellent for diagnosing caries and periodontal conditions, they don't contribute the critical information needed during implant procedures, making them the least appropriate choice in this context.
