After the Benex extraction, there are no fracture lines on the bucco-labial alveolar wall.

Only in rare cases (such as bridge abutment extraction, immediate implant placement) does mucosa-flapping occur in Benex extractions, thus enabling the alveolar wall to be seen from a vestibular direction:

After a Benex extraction the buccal wall is usually only visible from an intra-alveolar direction.
