Electromyographic analysis of the buccinator mechanism in human beings

Electromyography of the muscles of the "buc-cinator mechanism " was undertaken, utilizing inzdwelling fine-wire electrodes. Electromyo-grams wvere made of 14 subjects with normal occlusion during various oral activities. Several activities elicited simultaneous contraction of all muscles. Simultaneous activity represents a potential restraining force of this muscular band on the dentition. J Dent Res 56(7): 783-794 July, 1977. An clectromyographic investigation of the mus-cles forming the buccinator mechanism was initiated to define the normal functional rela-tionships of the components of this muscular unit: the orbicularis oris, the buccinators, an
