ABSTRACT
Objective:To evaluate the subjective feeling and the objective chewing effect of the patients with the prosthesis made for upper jaw defect by altered cast impression technique.Methods:A self-control experiment was conducted for 30 patients with the pros-thesis made for upper jaw defect by specific tray impression technique and altered cast impression technique respectively.As soon as the impression was finished,the patients were required to finish 2 questionnaires,one was about their self-comfortable sensation and the other one was the STAI(State-Trait Anxiety Inventory)about their feeling of anxiety.Then the chewing-effect was tested.Data were analysed by SPSS 20.0 software (T-test and Rank-sum test).Results:Most prosthesis made by altered cast impression technique showed increased masticatory function(P <0.05).The subjective-felling evaluation indicated that the altered cast impression technique was more comfortable but there was no difference between the 2 methods in the whole course of the impression(P =0.051).STAI score showed that the patients suffered lower anxiety with altered cast impression.Conclusion:The altered cast impression technique can en-hance masticatory efficiency and increase the satisfaction of patients for preparation of the posthesis for upper jaw defect.
