CIT CIT Radiography & Imaging

Question 1

Which radiographic view is most commonly used for initial implant site screening because it captures both jaws in a single image?

Accepted Answer

Panoramic radiograph (OPG)

Answer

A panoramic radiograph provides a broad overview of both jaws, bone levels, sinus floors, and anatomical structures, making it the standard initial screening tool for implant planning.

Question 2

What is the primary diagnostic advantage of cone beam computed tomography (CBCT) over conventional 2D radiography for implant planning?

Accepted Answer

Three-dimensional visualization of bone volume, density, and anatomy

Answer

CBCT provides three-dimensional images that allow clinicians to precisely measure bone height, width, and density while identifying critical anatomical structures before implant placement.

Question 3

What does a radiolucent area surrounding an implant on a periapical radiograph most likely indicate?

Accepted Answer

Possible peri-implant bone loss, infection, or failed osseointegration

Answer

A radiolucent zone around an implant indicates a lack of bone contact, suggesting peri-implantitis, failed osseointegration, or progressive bone loss around the implant.

Question 4

What is the recommended minimum safety margin of bone between the apex of a mandibular implant and the mandibular canal?

Accepted Answer

2 mm

Answer

A safety margin of at least 2 mm above the mandibular canal is recommended to protect the inferior alveolar nerve from implant encroachment or vibration during drilling.

Question 5

Which CBCT measurement is most critical when selecting the appropriate implant diameter for a planned site?

Accepted Answer

Buccolingual bone width at the implant site

Answer

The buccolingual bone width determines whether sufficient bone exists to accommodate the implant diameter while maintaining adequate facial and lingual cortical bone walls.
