Which of the following is NOT a principle of atraumatic (minimally invasive) tooth extraction?

Atraumatic extraction (also called minimally invasive extraction) aims to preserve the alveolar bone and soft tissues to optimize healing and facilitate future implant placement or immediate implant protocols. The principles include: using periotomes and micro-elevators to sever the periodontal ligament, sectioning multi-rooted teeth to facilitate individual root removal, avoiding excessive force, and preserving the buccal cortical plate. Removing buccal bone is CONTRARY to the goals of atraumatic extraction — removal of buccal bone causes significant ridge resorption and compromises future implant esthetics, particularly in the anterior region.
