  1. Gums slowly change shape over months and years, and a denture that fit before can loosen
  2. It's lifted off so the fitting surface can be reached
  3. New material is added inside to match the new shape of the gums
  4. A soft reline can be done right there in the chair
  5. A bigger reline or a rebase instead means leaving it at the lab for a day
  6. Either way, it sits snugly again once it goes back in

general dentist. Done in any general office.

One question worth asking

Will I be without the denture while this is done?

Chairside reline, lower partial

DenturesBasicD5741

D5741. Same-day reline of a lower partial.

Gums change shape over time and a denture loosens. A reline adds new material to the inside of the denture so it fits again; a rebase replaces the whole pink base. Codes differ by full or partial denture and by whether it is done in the office or sent to a lab.

New material is added to the fitting surface so the denture meets the changed shape of the gums again. A soft reline can be done in the chair in one visit; a lab reline or a rebase means leaving the denture for a day or so. A rebase replaces the whole pink base and keeps the teeth. Most plans file this as Basic. What they actually pay varies by plan.
