Prosthodontics & Occlusion · patient case question
He also reports localised burning beneath the denture. This is most likely due to:
Patient case: Denture wearer with uncontrolled systemic disease requiring extraction
Patient: Adult denture wearer requiring an extraction
Chief complaint: Requests removal of a broken-down tooth; also reports burning under the upper denture.
Background: Hypertension and diabetes, both treated with medication. Has worn the same maxillary prosthesis for many years and does not remove it at night.
Vital signs / labs: Blood pressure 150/100 mmHg. HbA1c 7.5%
Current findings: On removing the prosthesis, the palatal mucosa in the bearing area shows a pebbly, cobblestone appearance.
Show answer and explanation
Correct answer: C. Excessive occlusal force
- A. An over- or under-extended post dam causes retention problems or gagging, not localised burning.
- B. An unpolished or rough intaglio surface causes generalised soreness and traps plaque, but the recall specified a localised burning attributable to overload.
- C. Localised burning under a denture base most commonly reflects a focal pressure or overload area, where excessive occlusal force is concentrated on a limited area of mucosa. Relief of the pressure spot and occlusal correction resolve it.
- D. True acrylic allergy is genuinely rare. Residual monomer in an inadequately cured base can cause a burning sensation, but this is uncommon and typically generalised.
