Frontal projection teleradiography is indicated for evaluating which malocclusion?

• A. hypodontia
• B. sagittal malocclusions
• C. transverse malocclusions
• D. vertical malocclusions

Answer: (D)

Frontal projection teleradiography is valuable because it shows the vertical relationships and symmetry of the midface in the frontal plane. In vertical malocclusions, the key concerns are the vertical dimension of the face, the tilt of the occlusal plane, and any asymmetry in height between the two sides. This view lets you compare vertical heights on the left and right, assess how the occlusal plane relates to the mandibular plane, and quantify vertical discrepancies that contribute to a deep bite or open bite pattern. Other malocclusion dimensions are better assessed with different views: sagittal (AP) relationships are more clearly evaluated on lateral cephalograms, transverse width issues are better seen on PA or intraoral/posteroanterior assessments, and hypodontia is typically evaluated with panoramic or periapical imaging in addition to clinical exam. The frontal projection teleradiograph specifically highlights vertical dimensional discrepancies, making it the most appropriate choice for evaluating vertical malocclusions.
