Abstract

This study was performed to offer convenience to determine the vertical dimension of occlusion of edentulous patients by investigating the interocclusal distances at physiologic rest position, at speaking of /m/ sound, and some korean short sounds, that is, /mem/ and /beb/ sounds, which were found in our previous study with dentulous subjects. Ten edentulous subjects - 6 men and 4 women - were selected for this study. The frequencies at speaking of /m/, /mem/, and /beb/ sounds were analyzed with Computerized speech lab($CSL^{TM}$, Model 4300B, Software version 5.X, Kay Elemetrics Co. U.S.A.). And the interocclusal distances at physiologic rest position and at speaking of /m/, /mem/, and /beb/ sounds were measured with K6 diagnostic system(Myo-tronics, Inc. U.S.A.). The results of this study were as follows ; 1. In the acoustic analysis by Computerized speech lab, frequencies of sounds of edentulous subjects with complete denture at speaking of /m/, /mem/, and /beb/ were similar to those of dentulous subjects. 2. In the linear correlation by Pearson's correlation coefficient, the interocclusal distance at physiologic rest position was most similar to those of speaking /mem/ sound, secondly /m/ sound, and thirdly /beb/ sound(p<0.05). In reliability by Cronbach's alpha, the results were reliable with alpha value 0.97. 3. It was found by Levene's test for equality of variance that the difference between men and women in the interocclusal distances at physiologic rest position and at speaking of /m/, /mem/, and /beb/ sounds was not statistically significant(p>0.05).
