摘要

Background

Controlled mobilization of the maxilla is essential in Le Fort I osteotomies, particularly in selected skeletal Class III cases and situations involving difficult or complex mobilization. Traditional methods using Tessier mobilizing retractors may be associated with uncontrolled force application, slippage, and dentoalveolar injury.

Technique

This technical note describes an adjunctive technique using a 2.0 mm × 10 mm self-tapping screw (Synthes/KLS Martin) placed at the anterior nasal spine (ANS) to provide stable and controlled traction during maxillary mobilization.

Clinical Experience

The technique was applied in a small, non-comparative case series of seven skeletal Class III patients. Improved intraoperative control was observed, with satisfactory correspondence between planned and achieved maxillary positioning assessed clinically using occlusal splint seating and intraoperative verification, along with stable outcomes during 6–12 months of follow-up.

Conclusion

The ANS traction screw is a simple, safe, and cost-effective technical adjunct that enhances control during maxillary mobilization in selected orthognathic cases. It is intended to complement, not replace, established mobilization techniques. The technique has a short learning curve and requires minimal instrumentation.
