The most appropriate flap design for a SURGICAL tooth extraction is:
Show answer and explanation
Correct answer: B. Full-thickness (mucoperiosteal) flap
- A. A partial-thickness (split-thickness) flap preserves the periosteum on bone — used for mucogingival surgery (e.g., free gingival graft), NOT surgical extractions where bone access is needed.
- B. Correct. A full-thickness (mucoperiosteal) flap reflects the epithelium, connective tissue, and periosteum together, providing direct access to the underlying bone. It is the standard flap design for surgical tooth extractions because it: (1) provides maximum visibility and access, (2) allows bone removal if needed, (3) heals well with primary closure.
- C. The Neumann flap is a periodontal full-thickness flap variation — not the standard for surgical extraction.
- D. The modified Widman flap is a periodontal surgical technique for root debridement access — not used for tooth extraction.
