Orthodontics · single question

Orthodontic uprighting of a mesially tipped mandibular second molar (into a missing first-molar space) typically results in:

  1. Increased overbite
  2. Decreased overbite
  3. No change in the vertical occlusion
  4. Increased overjet
Show answer and explanation

Correct answer: B. Decreased overbite

  • A. Uprighting does not deepen the bite; it tends to open it.
  • B. Correct. Distal-crown movement/uprighting extrudes the molar and tends to DECREASE the overbite (open the bite slightly).
  • C. There is a predictable vertical effect.
  • D. Overjet (horizontal) is not the primary change.
