A crossbite is which type of malocclusion?
Show answer and explanation
Correct answer: A. Transverse
- A. Correct. A crossbite represents a transverse (width) discrepancy between the maxillary and mandibular arches, whether anterior or posterior.
- B. Sagittal/horizontal discrepancies describe anteroposterior relationships, classified as Class I, II, or III malocclusion — not crossbite.
- C. Vertical/axial discrepancies describe open bite or deep bite relationships, not crossbite.
Note: Horizontal = Sagittal (Class I, II, III) | Vertical = Axial (open bite/deep bite) | Transverse = Crossbite.
