What major connector do you use for a patient with a gag reflex for a Removable Partial Denture (RPD)?
Show answer and explanation
Correct answer: A. U-shape (horseshoe) connector
A) U-shape (horseshoe) connector — CORRECT.
The U-shaped (horseshoe) palatal connector is preferred in patients with a gag reflex because it avoids coverage of the posterior palate, which is the area most sensitive to triggering the gag reflex. It leaves the posterior palate open.
B) Double bar: Used for stability but covers the mid-palate and can still stimulate the gag reflex. Not first choice for this indication.
C) Palatal strap / D) Single palatal bar: Both span the palate and may contact the sensitive posterior region, making them less ideal for gag-prone patients.
