Bonded Rapid Maxillary Expansion
Bonded-hyrax with a 7mm expansion screw activated a full turn twice daily
Bonded-Hyrax
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
Bonded Rapid Maxillary Expansion and low-Level Laser
Bonded-hyrax with a 7mm expansion screw activated a full turn twice daily with 10 sessions of Indium Gallium Arsenide Phosphoride (940nm) semiconductor diode laser
Bonded-Hyrax
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
Bonded Rapid Maxillary Expansion and low-Level Laser therapy
Ten sessions of 0.5 watts for 20 seconds at 4 points along the mid-palatal suture
