The influence of denture changes, occurring during a period of use ranging from one to 15 years, was studied in a group of 35 complete denture subjects. Clinical and electromyographic data were collected. N0 correlation was found between denture serviceability on the one hand and masticatory performance and muscular coordination during chewing of test food on the other. However, a significant correlation was found between a subject's satisfaction and his masticatory performance, as well as his muscular coordination during chewing of test food. It appears that, as soon as the time-linked and insidious imperfections of complete dentures are compensated for by feedback-controlled neuromuscular adaptation, the subject's adjusted pattern of function does not affect his performance and comfort and consequently his satisfaction. Despite the obvious differences among the respective subjects, the number of masticatory strokes in the same individual was rather constant. Obviously, a subject's satisfaction may easily camouflage lack of denture fit, including its potential concomitant pathologic sequelae. Therefore, periodic examinations and adequate corrections are essential to successful complete denture treatment.
