“…10 The 11 This study evidenced more force in the masseter muscles of men, which the authors attributed to muscle size, although this gender-related asymmetry has not been observed in previous studies. 6 Therefore, in confirmation of the conclusions of the authors and others, 5,[7][8][9] it seems that the muscular electrical activity recorded by surface EMG provides a useful and reproducible functional guide to mandibular mechanics in healthy subjects. EMG can assist in understanding variations in muscular behavior 8 in patients with prostheses, malocclusion, craniomandibular syndromes or muscular diseases.…”

“…La evaluación electromiográfica ha sido utilizada por diferentes autores en los últimos años no solo para el conocimiento de la mecánica mandibular: 3-6 estudios centrados en la actividad de reposo, actividad en el esfuerzo máximo, balance muscular y simetría muscular sino también para el conocimiento de las alteraciones que producen numerosos síndromes craneomandibulares de origen muscular: 7,8 …”

“…11 En este estudio se evidencia una mayor fuerza en los músculos maseteros de los hombres relacionada por los autores con el tamaño muscular, aunque esta asimetría en relación al sexo no es objetivada en otros trabajos previos. 6 Parece por lo tanto y apoyando las conclusiones de los autores, como las de otros autores previamente, 5,7-9 que la actividad eléc-trica muscular registrada mediante EMG de superficie aporta una guía funcional útil y reproducible de la mecánica mandibular en sujetos sanos y puede ayudar a entender las variaciones del comportamiento muscular de estos músculos en pacientes portadores de prótesis, 8 con maloclusiones, síndromes craneomandibulares o enfermedades musculares.…”

Abstract:The Lucia jig is a technique that promotes neuromuscular reprogramming of the masticatory system and allows the stabilization of the mandible without the interference of dental contacts, maintaining the mandible position in harmonic condition with the musculature in normal subjects or in patients with temporomandibular dysfunction (TMD).This study aimed to electromyographically analyze the activity (RMS) of the masseter and temporal muscles in normal subjects (control group) during the use of an anterior programming device, the Lucia jig, in place for 0, 5, 10, 20 and 30 minutes to demonstrate its effect on the stomatognathic system. Forty-two healthy dentate individuals (aged 21 to 40 years) with normal occlusion and without parafunctional habits or temporomandibular dysfunction (RDC/TMD) were evaluated on the basis of the electromyographic activity of the masseter and temporal muscles before placement of a neuromuscular re-programming device, the Lucia jig, on the upper central incisors. There were no statistically significant differences (p < 0.05) in the electromyographic activity of the masticatory muscles in the different time periods. The Lucia jig changed the electromyographic activity by promoting a neuromuscular reprogramming. In most of the time periods, it decreased the activation of the masticatory muscles, showing that this device has wide applicability in dentistry. The use of a Lucia jig over 0, 5, 10, 15, 20 and 30 minutes did not promote any statistically significant increase in muscle activity despite differences in the data, thus showing that this intra-oral device can be used in dentistry.

“…This is likely due to bone and muscular changes in the stomatognathic system of individuals with malocclusion. [1011] In habitual gum chewing and dental clenching, there was a statistically significant difference in the activities before and after SARME ( P < 0.01). In mouth opening and closing and at rest, just for the right temporal muscle, the data was statistically significant ( P < 0.05).…”

Background:The aim of the present study was to analyze the electromyographic (EMG) activity of masseter and temporal muscles of adult patients submitted to surgically assisted rapid maxillary expansion (SARME) before and after the surgery.Materials and Methods:The sample consisted of 19 adults, with ages ranging from 20 to 47 years (mean 25.4 years), with bilateral posterior cross bite requiring SARME treatment. The electromyographic activity of masseter and temporal muscles was analyzed before treatment (T1) and after the surgical procedure (T2). The mean interval between the two electromyographic analyses was 15 days.Results:The muscular active was electromyographically analyzed during the clinical situation of habitual gum chewing (10 sec), dental clenching (4 sec), mouth opening and closing (10 sec), rest (10 sec), protrusion (10 sec), and right and left laterality (10 sec). The measured differences between T1 and T2 data were evaluated using the paired t-test (SPSS 17.0 for Windows). The electromyographic analysis showed that the activity of the masseter and temporal muscles decreased significantly after the SARME in all the clinical situations after the surgery.Conclusion:According to the results of the present study, individuals after SARME surgery presented patterns of electromyographic contraction similar to those developed by dentate individuals during the movements of mandibular excursion.

Electromyographic evaluation of masseter and anterior temporalis muscles in rest position of edentulous patients with temporomandibular disorders, before and after using complete dentures with sliding plates

Abstract: The sliding plates allowed the process of neuromuscular deprogramming, contributing to muscular balance of the masticatory system, and are therefore indicated to be used before the fabrication of definitive complete dentures in patients with TMD.
