The recommended extraction sequence in the maxillary segment begins with the 3rd molars and progresses anteriorly to the canines to facilitate surgical access and minimize trauma. Removing posterior teeth first (3rd molars, 2nd molars, then premolars) creates the necessary space and visibility for subsequent extractions of more anterior teeth. Extracting anterior teeth prematurely can complicate flap design and healing. Additionally, this order helps preserve alveolar bone and soft tissue contours for potential prosthetic or orthodontic procedures. Overall, the sequence optimizes surgical efficiency and patient outcomes.
