Laser Scanner (Vivid 9i® - Konica Minolta)was used to digitize the study casts. After scanning the dental casts a 3D virtual dental casts was used to realize all measurements (pre-treatment, 4 months and 10 months).
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.
Surgically Assisted rapid Maxillary Expansion -SARME was used for the treatment of transverse maxillary deficiency.This procedure is a combination of a surgical procedure and orthopedic expansion of the maxilla.
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.
