Removable Denture Assisting · CDA

Why is periodic relining of a removable denture sometimes necessary after delivery?

To change the colour of the acrylic denture base
Because the acrylic teeth wear down very quickly
To re-adapt the base to the changed ridge
To convert a partial denture into a complete one

Show answer and explanation

Correct answer: To re-adapt the base to the changed ridge

Over time, alveolar ridge resorption or tissue changes can lead to poor denture fit; relining re-adapts the base to the current tissue contours, improving retention and comfort.
