A patient with an RPD complains of burning sensation in the mandibular buccal area near the premolars. What is the most likely reason?
Show answer and explanation
Correct answer: A. Overextension of the borders
- A. Burning in the buccal vestibule near premolars is classic for border overextension — the RPD flange extends too far into the movable buccal mucosa/vestibule, causing irritation and burning.
- B. Allergy causes diffuse burning over the entire contact area, not localized to the buccal premolar region.
- C. A high pressure point on the internal surface would cause a localized ulcer directly under the denture base.
- D. Unpolished surfaces cause general tissue irritation; the specific buccal/premolar burning pattern indicates border overextension.
