“…It is intriguing to hypothesize that when opposing occlusal contacts occur, the central nervous system directly receives refined peripheral inputs from periodontal, muscular, oral receptors and a strict motor control of the mandibular movement, with very little freedom, is established to avoid the occlusal contacts 21,25 .…”

“…When they are represented in high percentage during chewing on one side only, as it happens in patients with unilateral posterior crossbite 21 , the activity of the masseter of the crossbite side, is reduced in comparison with the normal side, resulting a functional asymmetry. The reduction in the percentage of reverse sequencing chewing cycles is of utmost importance for decreasing the altered muscular activity and the functional asymmetry 13 .…”

“…It is well established that patients with a unilateral posterior crossbite, when chewing on the affected side, show an increased frequency of reverse sequencing chewing cycles in the frontal plane [20][21][22][23] . Reverse chewing cycles are characterized by altered muscular activation corresponding to altered kinematics and altered pattern morphology 24 .…”

In most cases authors Materials and methods:Twenty children, (9 boys, 11 girls; age, mean ± SD, 7.5 ± 1.1), 10 with a right and 10 with a left posterior unilateral crossbite were selected. Mandibular movements during chewing soft and hard boluses were measured with a kinesiograph (K7 -I, MyotronicsInc. Tukwila, Washington, USA). Results:The results showed a significant difference when comparing the percentage of reverse chewing patterns, before and after therapy with FGB, during chewing on the crossbite side both with soft and hard bolus (p < 0.0001). No significant differences were observed during chewing on the non-crossbite side. Discussion:The results of this study confirmed that FGB corrects both the dental and functional asymmetries. Knowing that the rapid palatal expansion does not correct the masticatory function, it is of clinical relevance, for the orthodontists, the knowledge and the understanding of the functional outcomes with different therapies. Conclusions:The type of treatment and the biomechanics of the appliance used are of great importance for the correction of the reverse chewing cycles and for rebalancing the functional asymmetry of children with unilateral posterior crossbite.

“…This allowed a more comprehensive analysis of the mandibular motion compared to that allowed by studies that focused on the jaw movement at the incisor point. 19,20 During the movements of opening and closing with manual retrusion of the mandible, the 1-pixel points that suffered least spatial dislocation were those closest to the TMJ region. This localization could provide support for the debate about terminal axis rotation (Bisagra axis) as being situated in the condyles.…”

This study aimed to present a wireless mandibular motion tracking device and optoelectronic data acquisition system developed to analyze the real-time spatial motion of the entire mandible during mouth opening and closing with no restriction of any movement. The procedures were divided into three phases: confection of a kinematic arch, dynamic digital video image acquisition, and image processing and analysis by using graphic computation. Four sequences of jaw opening/closing movements were recorded in lateral view: two from the maximum intercuspation (MIC) and the other two from a forced mandibular retruded position. Jaw motion was recorded by a digital video camera and processed as spatial coordinates corresponding to the position variation of the markers in the kinematic arch. The results showed that the method was capable of recording and processing the dynamics of the mandibular movements during jaw opening/closing using pixel-magnitude points. The mandible showed points with less displacement located near the temporomandibular joint during the opening/closing movements from the mandibular retruded position. When the jaw movements were recorded from MIC, these points were located near the mandibular foramen.

“…ND can be defined as a diagnostic and treatment procedure in which the triad of the teeth, temporomandibular joint (TMJ), and masticatory muscles, is considered clinically. Dr. Bernard Jankelson introduced this methodology in the late 1970s [1][2][3][4][5][6][7] , although there has been limited application of neuromuscular dentistry for orthodontic purposes. Such combinatorial approaches not only increase the amount of physiological data that can be obtained, but also allow for relationships between different systems to be inferred; i.e., how a defect in the mandibular ramen influences joint congruity and masticatory function.…”
