“…Another method to record bite force is indirect evaluation by means of electromyography. It has been observed in various investigations that there is a linear relationship between direct force measurement and electromyographic activity potential [3,4].…”

“…As said above, these muscles are all connected to the particular disk [3]. Surface electromyography has been used for years to assess muscle output and to study the activity of most muscles of mastication [5][6][7][8][9][10][11]. This technique is generally used to evaluate the Masseter, Digastricus, Temporalis and Sternocleidomastoideus muscles during mandibular movements and mandibular rest position.…”

The controversy on dental occlusion has been an issue since the time dentistry was born. No other definition has been studied and written most then that regarding occlusion. With no doubt, initially, "occlusion" was seen as the result of technical and biomechanical applications: a static relationship of contact between two dental or prosthetic arches. Studies on anatomy of the dental arches and physiology of the stomatognathic system, have contributed to understanding how occlusion develops in a unique fashion for each individual. Nevertheless it's only with the study of the function of the stomatognathic system, along with progress in the development of new diagnostic technological instruments, that we can finally add precious information for a new, more modern definition of dental occlusion.Specifying an ideal occlusion is important because we can extrapolate precious information that could be applied when creating our smiles. The therapeutic information we gather comes as a result from what we define as a malocclusion and it's comparison to an ideal occlusion. Our ultimate goal, be it in general prosthetics or orthodontics, is to get as close as possible to achieving an ideal occlusion.

Objective: To evaluate variation of electromyographic (EMG) activity and sensitivity between different sites of anterior temporalis (AT) muscle. Material and methods:Sixteen healthy subjects (eight men: 28.8 ± 5.2 year old and eight women: 29.1 ± 3.9) participated in one experimental session. EMG activity during masticatory muscle contraction was recorded from nine sites at the AT muscle in 3 x 3 grid with 1 cm between. The subjects maintained steady 30% of maximal voluntary contraction (MVC) using visual feedback. The surface EMG electrode was moved sequentially between these nine test sites and the contractions were repeated. One site was tested four times to assess test-retest variability. The sensory threshold to electrical stimulation and impedance was also measured at the same sites as the placement of EMG electrodes. Results:The 30% MVC force values did not differ between sites (P = 0.863) or within the same site (P = 0.995) due to the feedback. The EMG activity during 30% MVC was highest at the anterior-superior site (P < 0.05) with a marginal difference within the same site (P = 0.044). Impedance was higher at the posterior-superior, posterior-middle, and posterior-inferior sites (P < 0.05). The sensory threshold was highest at the posterior-superior site (P < 0.05). Conclusions: These findings showed that electrodes close to the hairline have higher impedance and sensory thresholds and should be Acta Odontol Scand 13/03/2012 3 avoided. The anterior-superior site produces the highest EMG activity and lower sensory thresholds and can be recommended as the optimal site to place the electrode for contingent stimulation.
