Summary

The objective of this study was to evaluate the effect of the orthodontic retainer on transverse maxillary dental and skeletal stability after SARME.

Conditions

  • Maxillary Hypoplasia

Interventions

PROCEDURE

Surgically Assisted Rapid Maxillary Expansion (SARME)

Surgical technique is performed with subtotal LeFort I osteotomy with separation of the pterygomaxillary fissure.The procedure was performed under general anesthesia using endotracheal intubation. Following the osteotomies, the expander screw was activated to 1.6 mm intraoperatively until a small diastema was observed between the upper central incisors. The incision was sutured along two planes.

OTHER

Laser Scanner

Laser Scanner Vivid 9i was used to digitize the study models. The 3d virtual dental casts is a reliable copy of the original dental casts. On this virtual casts all measurements (linear, area and volume of the palate) was done to evaluate the stability after SARME.
