The Only Anterior Open Bite Treatment That Is Predictable in the Absence of Myo Issues

Dr. Amanda from Straight Smile Solutions explains why anterior open bite (AOB) is one of the least predictable orthodontic problems unless the case is selected correctly. The key to success is identifying the true etiology of the open bite and understanding when orthodontics alone can, and cannot, deliver stable results.

• Identify the True Cause First
  • Every anterior open bite must be classified as skeletal, myofunctional, or both.
  • Myofunctional issues (tongue posture, cheeks, airway) often cause skeletal changes.
  • A full diagnostic workup is mandatory: CBCT, ceph analysis, airway screening, and formal myofunctional therapy evaluation (not just in-office screening).
• Why Most AOB Treatments Fail
  • Treating the teeth without addressing myo or airway issues leads to instability and relapse.
  • Posterior intrusion and anterior extrusion are slow, unpredictable, and can devitalize teeth.
  • Fixing skeletal relationships does not automatically resolve underlying myofunctional habits.
• When Orthodontics Becomes Predictable
  • The only predictable scenario is when all myo and airway issues have been fully resolved.
  • The patient presents with:
    • Class I skeletal and transverse relationships
    • No sagittal or anterior interferences
    • A mild residual anterior open bite
  • In select cases with significant incisor flaring, the wedge effect (retraction mechanics) can close the bite only if airway considerations allow.
• The Most Stable Solution
  • Instead of forcing extrusion or intrusion, Dr. Amanda recommends:
    • Aligning teeth conservatively
    • Preserving tooth vitality
    • Using restorative dentistry (veneers or additive restorations) to finalize incisal display and closure
  • This hybrid ortho–restorative approach offers the highest predictability and stability.

Conclusion

Anterior open bite cases should be approached with extreme caution. Unless myofunctional and airway issues are fully corrected, orthodontic treatment alone is unlikely to succeed. The most predictable option when biology allows is conservative alignment followed by restorative correction. Without this clarity, Dr. Amanda’s advice is simple: do not treat anterior open bites; they will disappoint you.
