Abstract
In comparison with the typical four first premolar extraction for protrusive and severe crowding cases, atypical extraction was more frequently used in borderline cases and cases with tooth size asymmetry, unfavorable tooth impaction, tooth dysplasia, premature tooth missing, severe malpositioned tooth, periodontal problems, etc. When atypical extraction happened, which teeth will we put the XBT on? Should first premolar be bonded or not? This chapter will introduce the flexible application of PASS technique in complicated atypical extraction cases.
