Variation in Anterior Temporal Muscles’ Electromyogram in Accordance With Herbst in Situ

摘要: Orthodontists need to inform patients of different appliance alternatives, extent expected success during the consultation stages. However they still could not predict degree treatment success. Power spectral density (PSD), energy power and area under signals may be an index evaluate effect these appliances. For this aim, variations in features anterior temporal muscle’s electromyogram are analyzed. Because having non stationary character EMG signals, PSD graphics derived using AR method. The study sample consisted 10 patients, 7 13 years old. These treated orthodontically with a Herbst which is one oral recordings without situ were obtained when was started use. When we look at findings values, maximum muscles’ placed smaller than their all patients.
