Evaluation of mandibular rest position in subjects with diverse dentofacial morphology

Effect of hypnosis on masseter EMG recorded during the ‘resting’ and a slightly open jaw posture

“…It is thought that the viscoelastic forces in soft tissues are responsible for sustaining the mandible in the rest position . On the other hand, many consider the mandibular rest position to be actively maintained by the masticatory muscles, and therefore, it should be possible to record EMG activity from these muscles . The present study involved the recording of EMG activity at resting posture and a slightly open position and supports the latter school of thought.…”

Kinesiographic study of the mandible in young patients with unilateral posterior crossbite

“…Different authors have stated that the vertical dimension is smaller in dolicofacial patients than in brachyfacial subjects. [24][25][26] Other possible sources of variation are the position of the head, the loss of teeth, emotional tension, aging, and breathe pattern. 23,27,28 The results confirm that the UPCB does not affect the vertical dimension of the freeway space.…”

Skeletal Sagittal and Vertical Facial Types and Electromyographic Activity of the Masticatory Muscle

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Also, craniofacial morphology is known to be related with biting force 2,9,10,15,19 or with resting activity of the masticatory muscle. 14,[20][21][22][23] In the study of the relationship between Angle classification of malocclusion and the masticatory muscle activity, Miralles et al 14 reported that resting activity for masticatory muscle was higher in subjects with Class III malocclusion than in subjects with Class I and II malocclusion. However, during maximal voluntary clenching (MVC), activity was not different among Class I, II, and III malocclusions.…”
