Oral Surgery · single question

When performing a routine dental extraction, all of the following are correct EXCEPT one. Which is the EXCEPTION?

  1. The beaks should be placed as apically as possible on the root
  2. The beaks of the forceps should be placed on the crown of the tooth
  3. A buccal-lingual rocking motion is used to expand the alveolus
  4. The beaks should be positioned along the long axis of the tooth
Show answer and explanation

Correct answer: B. The beaks of the forceps should be placed on the crown of the tooth

  • A. Placing beaks as apically as possible on the root improves mechanical advantage and reduces the risk of crown fracture.
  • B. CORRECT. The beaks of extraction forceps should NEVER be placed on the crown — they should be placed apically on the root, grasping as far apically as possible below the CEJ. Placing beaks on the crown risks fracture of the crown, especially in compromised teeth.
  • C. Buccal-lingual rocking motions progressively expand the alveolar socket, stretching the periodontal ligament and allowing controlled tooth removal.
  • D. Positioning the beaks along the long axis of the tooth ensures proper force application and reduces the risk of root fracture.
