A PFM prosthesis is poorly adapted and cannot be re-cemented. What is the most appropriate next step?
Show answer and explanation
Correct answer: B. Take alginate impression for new study models
- A. ❌ Adjusting the internal surface without new models is not the standard approach when remaking is indicated.
- B. ✅ Correct. When a PFM is identified as poorly adapted and cannot be properly re-cemented, the next step is to take ALGINATE IMPRESSIONS for new study models — initiating the remake process with accurate current models.
- C. ❌ Re-cementing a poorly adapted prosthesis is contraindicated — it will fail and may harm the abutment.
- D. ❌ If the prosthesis is already identified as problematic, removal may occur but the question asks about the 'next step' in management.
