There are several forces that try to displace the denture away from the path of insertion. If extension of denture is too far in the sulcus than the muscular movement can result in displacement of denture along with sulcus ulceration.If it is less extended into sulcus there is less retained saliva and the loss of retention.The upper denture is extended as far as possible but not on the soft palate.This shows that the posterior seal is not present.It is obtained if the displaced tissue also move with the denture during function.This can be done by making post dam area by creating raised grooves on posterior surface.
