Which statement best describes eruptive movements in eruption?

• A. Both axial and occlusal movements occur
• B. Axial movement only
• C. Occlusal movement only
• D. Neither axial nor occlusal movements occur

Answer: (A)

Eruption involves two coordinated movements: a bodily rise along the tooth’s long axis toward the occlusal surface (axial eruption) and changes in the tooth’s position within the occlusal plane as the surrounding bone remodels and the opposing teeth come into contact (occlusal movement). Both processes work together so the tooth moves upward and seats properly in the bite. If only one type of movement occurred, the tooth wouldn’t achieve correct alignment or occlusion.
