Summary
Symphyseal distraction using a dental-anchored device effectively treats mandibular deficiency, increasing inter-canine width without complications. This simplified technique offers a reliable alternative to tooth extraction for severe crowding.
Area of Science:
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- Severe mandibular incisor crowding with bone insufficiency often requires dental extractions.
- Symphyseal distraction is an alternative but considered invasive and complex.
- This study evaluates a simplified symphyseal distraction protocol.
Purpose of the Study:
- To clarify indications for symphyseal distraction.
- To propose a simplified surgical protocol for mandibular expansion.
Main Methods:
- Six patients underwent symphyseal distraction (3 bone-anchored, 3 dental-anchored).
- Pre- and postoperative inter-canine measurements and occlusal stability were analyzed.
Main Results:
- Inter-canine width increased by a mean of 5.2mm (3.4mm to 6.8mm).
- All patients achieved Angle class I occlusion without complications.
- Dental-anchored devices simplified the surgical procedure.
Conclusions:
- Dental-anchored symphyseal distraction is a simple, efficient, and reliable method for severe transverse mandibular deficiency.
- Orthodontists can manage this procedure independently.
- The technique allows controlled expansion based on specific patient needs.
