Due to severe crowding (Fig.4), four of the 1st bicuspids are extracted prior to separator placement.  It appears that spaces are easier to open up for molar bands with extraction first. Choose 2nd molar bands with lingual cleats so that 2nd molar cross bite will be corrected immediately post banding.  In fact, it is not feasible because of limited space posteriorly.  Instead brackets are placed for the upper, lingual buttons are placed for the lower.
