Figure 1.

(A) After the miniplates were placed into the zygomatic buttress areas, three self-tapping type screws per side were used to fix the miniplates. (B) The distal end of the miniplate was exposed through the attached gingiva between the maxillary deciduous canine and deciduous first molar or between the maxillary permanent canine and first premolar to control the vector of elastic traction. Four to eight weeks after miniplate placement, their mobility was assessed and the distal end hole of the miniplate was cut to make a hook for elastics. (C) A conventional banded or bonded RME appliance was used as a tooth-borne anchorage for extraoral elastics.
