Denture Relines

Denture Reline/Rebase

With time, shrinkage of denture supporting bone and gums occurs. Most rapid and pronounced shrinkage happens within 6-12 months after tooth extractions, and then it slows down and continues gradually throughout the patient’s life. This creates empty space between the denture and patient’s gums, which results in poor fit and problems with function. Denture relines can be done to fill in the empty space and adapt the denture to the current condition of the gums. There are two types of relines. Soft relines are performed during the healing process within the first 6-12 months after extractions. Hard relines are done in permanent dentures which have been worn for a long time during which the gums have gradually shrunk away. An examination of the patient’s oral cavity and the denture is needed prior to reline to ensure that the denture is not excessively damaged/worn out and that the bite is correct.

Rebasing is recommended when the teeth of the denture are still in good condition and have not worn out in comparison to the denture base material. Rebasing is the process of replacing the entire acrylic denture base providing a stable denture without replacing the denture teeth. A rebase for a denture maybe required if your denture is old or is cracked. A rebase is very similar to relining, the difference being that, a rebase replaces all the pink-acrylic denture base material instead of just the lining.
