Active Comparator
Experimental
Conventional anchorage
Skeletal anchorage
Buccal tubes will be bonded on the lower first molars, an alginate impression will be taken for the lower arch with the buccal tubes in place, and a cast will be poured. A hard vacuum sheet of 1.5- mm thickness will be used to fabricate the Essix appliance. The posterior end of the buccal surface will be trimmed in each lower first molar region, creating a window to allow for attachment of the elastics. Class II elastics will be attached from the maxillary canine to the mandibular first molar bilaterally. During the first month, 1/4-inch heavy elastics will be used. In the following months, 3/16-inch heavy elastics will be used. The patients will be instructed to wear the elastics 24 hours per day, except during mealtimes, and to change them daily.
Closing coil springs will be attached from the maxillary canine to the infrazygomatic miniscrews bilaterally
