Impression materials, in the fluid or plastic state, are carried to the mouth in a suitably sized tray. Hardening of the material takes place either on cooling or through a chemical reaction.
There is no clear line between mucostatic and mucodisplacing impression materials.
Mucodisplacive : compound, high viscosity alginates, high viscosity elastomers.
These viscous impressions materials are called mucocodisplacive impression materials. These record an impression of the mucosa under load. This results in a wider distribution of load during function, making it more stable it also compensates for the differing compressibility of the denture bearing area reducing the risk of a fracture due to flexion. However the retention of the dentures may be compromised as the soft tissues wish to return to their original position at rest.
