Atraumatic extraction — which of the following is EXCEPT (should NOT be done)?

  1. Use surgical flap to improve access
  2. Separate roots before extraction
  3. Remove buccal bone
  4. Use periotome to sever PDL fibers
Show answer and explanation

Correct answer: C. Remove buccal bone

  • A. Raising a surgical flap (when necessary for impacted or ankylosed teeth) is an accepted surgical technique — it is NOT the exception in this context.
  • B. Separating multi-rooted teeth into individual roots IS part of atraumatic extraction — it allows each root to be removed along its own path of withdrawal, minimizing buccal plate fracture.
  • C. REMOVING BUCCAL BONE is NOT part of atraumatic extraction technique — it is the OPPOSITE of atraumatic. Atraumatic extraction aims to preserve alveolar bone by using periotomes, luxators, and careful sectioning of teeth to minimize bone trauma. Removing buccal bone causes ridge resorption and compromises implant placement and aesthetics.
  • D. Using periotomes to carefully sever PDL fibers IS part of atraumatic extraction — it loosens the tooth without requiring excessive force.
