Which term describes maintaining the erupted tooth position during jaw growth?

• A. Posteruptive tooth movement
• B. Preeruptive
• C. Eruptive
• D. Orthodontic movement

Answer: (A)

After a tooth has erupted, it can still adjust its position as the jaws grow. This ongoing adjustment is called posteruptive tooth movement. It describes natural changes in the position of erupted teeth to maintain proper occlusion and contact as the mandible and maxilla increase in size and change shape during growth.

This is different from preeruptive movement, which occurs before a tooth erupts while it is still within the bone, and eruptive movement, which happens as the tooth moves from the eruption path into its functional place in the mouth. Orthodontic movement, by contrast, refers to deliberate tooth movement caused by applied forces from appliances, not natural adjustments during growth.
