What term refers to refitting a denture by replacing the base material?

• A. Rebase
• B. Reline
• C. Interim denture
• D. Suture

Answer: (A)

Rebasing a denture is the process of replacing the denture base material while keeping the existing teeth intact. This restores the supporting base and fit when the base resin has worn, degraded, or become porous, without changing the position of the teeth or the bite. It differs from relining, which adds or replaces material on the tissue-facing surface to improve fit but does not replace the base itself. An interim denture is a temporary prosthesis used during transition, not a base replacement procedure. Suture relates to closing wounds and isn’t involved in denture base procedures.
