Sažetak
The activity of anterior et posterior temporal muscle was studied in 35
subjects with natural teeth and 30 subjects with full dentures, employing the method of surface electromyography by means of a device supplied with built-in digital integrators. Records were taken in all occlusal positions (i.e. retrusiion, incisal position, d extra- and sinistro-lateral occlusion, maximal intercupation). The results obtained were processed by the method of variance analysis and are presented as percentage of maximal interciuspation. A relatively higher activity of m. temporalis anterior in retrusion and lateral occlusion on the working side was found in the subjects with full dentures (p < 0 ,0 1 ), which was attributed to more frequent contacts on the lateral teeth in dentures in theise positions. In these subjects, a higher activity of m. temporalis posterior was also found in the incisal position and lateral occlusion on the -contralateral side (p < 0 .0 1 ), which was ascribed to less steep incisad angle in full denture wearers, as well as an upward and forward rotation of the mandible due to resonption of residual ridges .
