THE EFFECT OF RELINING ON THE FIT AND STABILITY OF COMPLETE DENTURES -AN IN VITRO AND IN VIVO STUDY

SUMMARY: A technique for estemating in vitro the accuracy of denture bases , using a low-viscosity impression material for determing the space between the die and the dentures upon it was developed. The measurements showed that relining denture bases with autopolymerizing acrylic resin improved their adaptation to the ridges. The in vivo study showed no statistically significant change in stability after relining , but the trend was toward increased stability with the relined dentures.
