Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Regenerative Medicine

Background:

  • Mandibular hypoplasia presents a significant challenge in pediatric patients.
  • Conventional orthodontic treatments may be insufficient for severe cases.
  • Distraction osteogenesis offers a surgical alternative for mandibular reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of distraction osteogenesis for correcting mandibular hypoplasia in adolescents.
  • To assess the outcomes of intraoral distraction in patients resistant to traditional orthodontic therapy.

Main Methods:

  • Bilateral intraoral distractors were used in 14 adolescent patients with mandibular hypoplasia.
  • Corticotomy was performed near the third molar, followed by a 6-day latency period.

  • A 6-week stabilization period was implemented post-distraction.

    • Main Results:

    • All patients achieved the planned mandibular lengthening and Class 1 occlusion.
    • Seven patients required adjunctive elastic band traction for open-bite correction.
    • Early technical issues (broken rods, incomplete distraction) were resolved with improved surgical mobilization.

    Conclusions:

    • Distraction osteogenesis is a viable and effective method for correcting mandibular hypoplasia in adolescents.
    • Careful surgical technique, particularly adequate mobilization, is essential to prevent complications.
    • The procedure can lead to timely orthodontic treatment completion.
