Brief Summary
The posterior crossbite is a common type of malocclusion that might affect the normal growth pattern. Early treatment is recommended by rapid maxillary expansion with different appliances. This line of treatment needs a sufficient retention period to decrease the rate of relapse. The low level laser therapy has been used to enhance tissue regeneration. This study aims to compare the effect of rapid maxillary expansion with low level laser versus rapid maxillary expansion in children with posterior cross bite malocclusions.

Study Arms (2)
Bonded Rapid Maxillary Expansion
ACTIVE COMPARATORBonded-hyrax with a 7mm expansion screw activated a full turn twice daily
Bonded Rapid Maxillary Expansion and low-Level Laser
EXPERIMENTALBonded-hyrax with a 7mm expansion screw activated a full turn twice daily with 10 sessions of Indium Gallium Arsenide Phosphoride (940nm) semiconductor diode laser
Interventions
The expansion screw of the bonded-hyrax will be activated until the palatal cusps of the permanent maxillary first molars are opposing the buccal cusps of the permanent mandibular first molars
Ten sessions of 0.5 watts for 20 seconds at 4 points along the mid-palatal suture
