In Frankel appliances, a small pad is placed against which structure to stimulate mandibular repositioning?

• A. Labial Mucosa
• B. Lingual Mucosa
• C. Buccal Mucosa
• D. Palatal Mucosa

Answer: (D)

FrankeI appliances work by guiding muscle function to change how the jaw is postured, not just by moving teeth. A small pad placed against the palatal mucosa acts as a tongue-positioning aid. It creates a space and gentle resistance that encourages the tongue to rest on the palate rather than pressing against the upper teeth. This altered tongue posture reduces forward pressure on the maxilla and helps balance the perioral muscular forces, allowing the mandible to assume a more forward position as the neuromuscular system re-educates itself. Pads on other mucosal sites mainly influence lips or cheeks and don’t nudge the mandible forward in the same direct, neuromuscular way, making the palatal pad the key structure for stimulating mandibular repositioning.
