During extraction of a mandibular molar, which of the following steps is INCONSISTENT with proper technique?
Show answer and explanation
Correct answer: A. Place the beaks on the crown of the tooth
Forceps beaks should be placed as apically (subgingival) as possible — placing them on the crown only is a technique error that risks crown fracture and reduces control of the root. All other options describe correct principles: apical placement, alignment with long axis, and lingual/palatal surface engagement first.
- A. CORRECT ANSWER (the EXCEPTION). Placing forceps only on the crown — rather than as far apically/subgingivally as possible — is incorrect technique and risks fracturing the crown.
- B. Positioning along the lingual surface first is correct technique for mandibular molars — the lingual plate is thicker and provides a stable anchoring point.
- C. Placing the beak as apically as possible is CORRECT technique — it maximizes root control and prevents crown fracture.
- D. Orienting forceps along the long axis of the tooth is correct — it allows for proper luxation forces along the periodontal ligament space.
