Abstract

This study was conducted to investigate the effect of weight change of upper complete denture on masticatory function in case of five maxillary edentulous patients who had adequate retention and stability. Duplicates of dentures were used as experimental dentures. In the denture, the groove was made buccally from right second molar to left second molar for the weight. Denture weight was changed to 20g of Pt-Au alloy and the area was covered with wax (H denture), or the weight removed and the whole area was covered with wax (L denture). Masticatory movements of Gumi chewing, denture vibration of tapping, patients estimate were recorded. These were recorded whether or not the subject recognized the denture weight.<BR>The results were as follows:<BR>1. When the subject did not recognize the denture weight, there was no significantly difference of masticatory movement and no distinction of comfortableness.<BR>2. When the subject recognized the denture weight, there were increased variations among subjects as to the coefficient variation and average variation of masticatory movements. Furthermore, only one patient complained about the H denture.<BR>3. There were no significant differences in duration of denture vibration.<BR>The above results indicated that the weight of upper complete denture does not affect masticatory movements, denture vibrations and patient estimate, if suitable retention and stability of the denture are maintained.
