A patient has remaining teeth #22-27 only. What prosthetic finding is most expected?

  1. Loss of interarch space
  2. Flabby ridge in the posterior region
  3. Loss of intraarch space
  4. Flabby ridge anteriorly with bone loss
Show answer and explanation

Correct answer: B. Flabby ridge in the posterior region

With only lower anterior teeth remaining against a full upper denture, chronic occlusal pressure on the posterior maxillary ridge from the denture causes fibrous replacement of bone — a flabby posterior ridge.
