An RPD patient with a partial metal framework returns with allergic contact dermatitis from the denture. What is the most appropriate management?

  1. Replace the RPD with a full denture
  2. Coat the metal framework with adhesive
  3. Prescribe antihistamines and continue use of the RPD
  4. Ask the lab which metal alloy was used and remake the RPD with a different, biocompatible alloy
Show answer and explanation

Correct answer: D. Ask the lab which metal alloy was used and remake the RPD with a different, biocompatible alloy

  • A. Full denture conversion is an extreme measure before investigating the specific metal allergy.
  • B. Coating the metal with adhesive does not address the allergy and the coating may wear away.
  • C. Antihistamines treat symptoms but do not address the causative metal allergy.
  • D. Correct. Contact dermatitis from an RPD indicates metal allergy (commonly nickel). The appropriate steps: (1) Identify which metal alloy was used by contacting the lab; (2) Allergy test or consult dermatologist to confirm the specific metal allergy; (3) Remake the RPD using a biocompatible alternative alloy (e.g., cobalt-chromium, titanium, gold alloy, or acrylic framework).
