Medial pterygoid muscle activity during chewing and clenching.
Specific activity of the human medial pterygoid muscle in relation to jaw movements and occlusion during mastication and clenching tasks is unclear. EMG activity of the medial pterygoid, masseter, anterior, and posterior temporal muscles was recorded simultaneously with three dimensional incisor point movement of the mandible. Data were sampled and analyzed by an on-line computer system. Patter...
متن کاملAn anatomical study of a muscle bundle separated from the medial pterygoid muscle.
When mandibular dentures are fabricated, marginal sealing should be taken into consideration for the stability of the denture. We selected specimens of the medial pterygoid muscle showing insertion of an independent small muscle bundle at its insertion site, and evaluated the anatomical relationship between the morphology of the insertion site and the denture. The insertion of the pterygoid mus...
متن کاملMyositis ossificans traumatica of the medial pterygoid muscle: a case report.
In this report, we present a case of myositis ossificans traumatica (MOT) of the medial pterygoid muscle that had developed after mandibular block anesthesia administered for endodontic treatment of the lower right second molar, demonstrating typical features of this condition. MOT should be considered as a differential diagnosis when there is severe limitation of jaw opening and an associated ...
متن کاملCo-activation of sternocleidomastoid muscles during maximum clenching.
In an attempt to determine the degree of co-activation present in selected cervical muscles during clenching, we instructed 12 male subjects to produce four brief maximum voluntary contraction (MVC) efforts (clenching) in a position of maximum intercuspation. Surface EMG activity was recorded bilaterally from the masseter and sternocleidomastoid (SCM) muscles. The contraction level for the SCM ...
متن کاملmyositis ossificans of the medial pterygoid muscles: a case report
myositis ossificans (mo) is a pathologic bone formation in soft tissue with unknown pathogenesis. in this article, we reported a case of long standing mo of right medial pterygoid muscle with severe limitation of mouth opening.
