A 70-year-old patient with controlled hypertension, who drinks half a glass of wine nightly, presents with a red lesion with a 'pebbly' appearance and has worn the same prosthesis for 50 years. What do you do BEFORE redoing a new prosthesis?

Correct answer: B. Resolve the pathological issue

• A. Taking impressions before addressing active pathology risks incorporating/aggravating the lesion and is premature.
• B. Correct. Any active oral pathology (here, an inflammatory/papillary hyperplastic 'pebbly' lesion likely from chronic ill-fitting denture use) must be diagnosed and resolved BEFORE proceeding with prosthetic treatment.
• C. Final impressions are even further along in the prosthetic workflow and inappropriate before treating the pathology.
