Abstract
The study of the efficiency of removable prosthetic therapy was
carried in 143 patients. The electromyographic method and the test of masticatory efficiency were simultaneously applied. The sample was divided in two groups. The experimental group consisted of 51 patients with the partial lower and the total upper prosthesis. The control group consisted of 92 subjects with preserved natural teeth. Two methods were applied in the electromyographic registration of the biopotential of both m. maseter and both m. temporalis: the serioelectromyogram method and the centra! occlusion electromyogram method. The masticatory efficiency test was carried out by the serioelectromyogram. On the basis of the obtained results it can be concluded that the patients with the partial lower and total upper prosthesis show a considerably lower masticatory efficiency. In subjects with natural teeth there is a higher correlation between the masticatory efficiency variables and the variables of the central occlusion electromyogram, while in patients with the partial lower and the total upper prosthesis there is a higher correlation between the masticatory efficiency variables and the serioelectromyogram variables.
