Summary

Maxillary expansion was performed for adult female patients suffering from maxillary constriction with bilateral posterior cross-bite using fixed Quad-helix appliance, for about 8 months. The appliance was delivered and activated at the day of corticotomy and bone graft. The activation was made half-molar unit each side. The patient was scheduled each month to activate the appliance or reactivate if needed. Corticotomy was performed at area of maxillary 1st premolar, 2nd premolar and first molar. Cone beam computed tomography was performed, before appliance activation and corticotomy, at the end of expansion (8 months) and after finishing orthodontic treatment (average 2.5 years from start of treatment).

Conditions

  • Posterior Cross Bite

Interventions

PROCEDURE

flap with corticotomy and bone allograft

A maxillary expansion with quad helix appliance was placed on the posterior teeth with cross bite. A Luebke buccal flap was opened in the area of maxillary 1st premolar, 2nd premolar and first molar with a no. 15 scalpel. Corticotomy procedure was performed using low speed round bur size 3, holes to create a 0.5 mm deep hole penetrating the cortical bone. Multiple holes were performed leaving 1.5 mm distance in between. The defects were covered with demineralized freeze-dried bone allograft and the flap was sutured in its original position with 3-0 black silk suture.
