Summary
Multisegmentation for transverse maxillary widening shows a slight tendency to relapse (0.3-0.8 mm) but yields highly satisfactory clinical outcomes in long-term studies.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Dental Research
Background:
- Transverse widening of the maxilla is a common orthodontic and surgical procedure.
- Assessing long-term relapse tendencies and clinical outcomes is crucial for treatment efficacy.
Purpose of the Study:
- To evaluate the long-term relapse and clinical outcomes of multisegmentation for transverse maxillary widening.
- To determine the stability of surgically achieved maxillary expansion.
Main Methods:
- A long-term prospective study involving 36 patients followed for 30 months and 13 patients for 60 months postoperatively.
- Multisegmentation technique applied to the palatal bone posterior to the canine teeth for transverse widening.
- Measurement of transverse widening (2 mm to 1.5 cm) and assessment of relapse and complications.
Main Results:
- No complications were reported following the maxillary operations.
- A tendency for relapse was observed, ranging from 0.3 mm to 0.8 mm.
- Significant transverse widening was achieved in the posterior maxilla.
Conclusions:
- Multisegmentation for transverse maxillary widening is a safe procedure with no reported complications.
- While a minor degree of relapse is expected, the overall clinical results are highly satisfactory.
- The technique provides stable and effective transverse maxillary expansion for long-term outcomes.
