The aim of this work was to analyse the presence of Temporomandibular Disorders (TMD) in subjects with dental prosthesis and compare their craniocervical posture the following conditions: without dental prosthesis, with the old dental prosthesis, with a new dental prosthesis and one month after placement of the new dental prosthesis. Electromyographic activity changes of the trapezius - descendents fibers, longissimus the beam lumbar after replacement of dental prosthesis was also evaluated. Prospective experimental study. Thirty one subjects with dental prosthesis, both genders, with a mean age of 62.5±9.42 years, mean body mass of 63±11 kg and average height of 1.6±0. 09 m. were analyzed. The instruments were the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), photogrammetry (craniocervical posture) and electromyography (EMG). There was a sample loss of eight individuals in the EMG evalubation group. EMG of trapezius descendents fibers muscles and longissimus the beam lumbar were registered. The relative frequency was used to statistical analysis of RDC/TMD results; Levene test followed by Tukey test was performed for photogrammetry analysis and multivariate Hotteling (T2) for EMG results. Results: The RDC/TDM results indicate that 48.38% (n = 15) of individuals analyzed were classified in group I, 22.56% (n = 7) classified as mixed TMD and 29.03% (n = 9) without TMD. There was no statistically significant difference in the conditions of the study in the photogrammetry results. For electromyography, statistical difference when comparing group I with group II in the assessment and reassessment. There was no statistical difference in comparison within the group I and II within the group. The presence of TMD in edentulous subjects using dental prosthesis is quite high. The craniocervical posture has not changed one month after the substitution of prosthesis. The results show that the EMG signals of the trapezius - descending fibers and longissimus thoracis - lumbar part is different between the groups with and without TMD and that the exchange of prostheses EMG pattern did not change in both groups.
