| Research Abstract |
The purpose of this research was to elucidate the each masticator muscle function, according to suppressing the selective muscle and analyzing each masticator muscle in detail, with animal model. One side of the masseter muscle of Japanese rabbit was injected botulinum toxin type A (BTXA), and the model rabbit for masseter muscle function restraint was made. The BTXA injected masseter muscle was observed atorophy of about 60% thickness of the control side muscle. And the telemetry system for electro myography was implanted in the rabbit. The electrode was inserted to the masseter muscle and temporal muscle, and the transmitter was inserted shoulder area subcutaneously.
