Summary
This study introduces a simple hyrax expander for mandibular midline distraction osteogenesis, successfully creating 7.01 mm of space. The method is a viable option with minimal complications for mandibular arch expansion.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Regenerative Medicine
Background:
- Mandibular midline distraction osteogenesis offers a novel approach for increasing intra-arch space.
- Effective techniques are crucial for successful mandibular expansion and orthodontic treatment.
Observation:
- A simple hyrax expander was utilized as a symphyseal distractor in 24 patients.
- Distraction was performed at 1 mm daily, divided into two 0.5 mm increments.
- The mean distraction achieved was 7.01 mm across the mandibular midline.
Findings:
- Mandibular midline distraction using the hyrax expander was successful in all patients.
- The procedure resulted in significant intra-arch space creation.
- Minor complications included mild mucosal irritation and gingival recession, with no major adverse events.
Implications:
- This method provides a viable and effective technique for mandibular midline distraction osteogenesis.
- The hyrax expander offers a simple and predictable solution for mandibular arch space creation.
- Further research can explore long-term stability and patient-reported outcomes.
