The tilt of the curve of Spee increases the crush/shear ratio of the force produced on food between the posterior molars. The parallel tilt of superficial masseter maximizes the efficiency with which this muscle contributes to the crush component of the bite force in the sagittal plane. ? 1993...
(maxillary) region of the zygomatic arch, level with the premolars, and runs obliquely backward to insert on the ventral margin of the mandible, including the angular process. The temporal muscle originates over a wide region of the cranium and inserts on the coronoid process. As the mandible...
The MMC was observed only in the electrically stimulated masseter muscle, and almost constant bite force without variation was generated in both molars (n = 6, Ipsilateral: 224.7 ± 11.08 g, Contralateral: 99.7 ± 11.08 g) (Fig.s 1A and 1B). Therefore, the electrical stimulation method used...
The facilitatory masseteric muscle response (FMR) elicited by polyurethane foam strip application between the opposing molars during cortically-induced rhythmic jaw movements (CRJMs) was induced earlier than masticatory force onset. The occurrence of this early response of the FMR (e-FMR) could not...
