Why it matters for dental

Orthodontists and periodontists must now factor GTR-treated intrabony defects into their timing and force-planning protocols, because tooth movement can measurably alter defect fill and attachment levels.

Key points

  • Randomised controlled trial (JCP EarlyView) assessed clinical attachment level (CAL) and radiographic bone fill after GTR when teeth were moved orthodontically versus non-moved controls.
  • Orthodontic movement initiated ≥6 months post-GTR resulted in an additional 0.7 mm mean radiographic bone gain compared with non-movement, without increased recession or probing depth.
  • Early tooth movement (<3 months post-GTR) produced 0.4 mm less bone fill and a higher rate of membrane exposure (18 % vs 6 %).
  • Specialists managing combined perio-ortho cases should delay active orthodontics until at least 6 months after GTR to maximize regenerative outcomes.
