[The effects of retention and adaptation of complete denture on masticatory efficiency].

There are many facts of effectiveness on complete denture.Retention and adaptation are very important to denture's function among them.This thesis used soft relining material for 22 complete denture's patients whose pain,non-retention and etc.resulted in the decline of masticatory efficiency to be treated.Masticatory efficiency is measured and analysed by light absorption method after treatment.The result shows there is closed relationship between full denture's retention and adaptation and masticatory efficiency.After relining,patient's masticatory efficiency is greatly improved due to increasing retention and adaptation.the masticatory efficiency after/before treatment is average 209%.Among these patients,mandibular changes are larger than maxilla.Author considers that soft relining is a good material for poor condition of alveolus dentis,mucosa and for old fragile man.
