Summary
This study shows that osteotomy-assisted maxillary posterior impaction significantly speeds up orthodontic treatment for severe open bite cases. This accelerated approach effectively corrects open bites with no adverse effects.
Area of Science:
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- Severe anterior open bite presents a significant orthodontic challenge.
- Traditional treatment methods for severe open bites can be lengthy and complex.
Observation:
- A 14-year-old patient with a severe anterior open bite underwent treatment involving osteotomy-assisted maxillary posterior impaction.
- Miniplates were used for anchorage, facilitating the intrusion of maxillary posterior teeth using nickel-titanium closed coil springs.
Findings:
- Maxillary molar intrusion of 4.0 mm was achieved in 2.5 months.
- The overall orthodontic treatment duration was reduced to 12 months.
- Optimal occlusion and correction of the anterior open bite were successfully obtained, with a counterclockwise autorotation of the mandibular plane by 3.0 degrees.
Implications:
- Osteotomy-facilitated orthodontic treatment offers a faster and effective solution for severe open bite cases.
- This one-stage osteotomy technique can be a valuable alternative for molar intrusion.
- The accelerated treatment shows no adverse effects, improving patient outcomes.
