Rebases and Relines
There are two different types of denture rebases and relines commonly available, hard relines and soft relines. Both types of relines can either be performed in office or chairside or by a denture laboratory; there are advantages and disadvantages to both methods. Since your mouth and the dental ridges change or shrink over time, a denture reline is necessary to keep your denture fitting well and to prevent your dental ridges from "shrinking" more rapidly.
Reasons for a Denture Rebases and Relines:
Better fit, a relined denture "stays in better"
A better fitting denture helps the dental ridges stay healthy
Helps a denture last longer
Helps with proper nutrition and health
