Study on compensatory function expression of masticatory muscles after the selective masticatory muscle restraint

本研究的目的是通过动物模型，通过对选择性肌肉的抑制和对每一块咀嚼肌的详细分析，阐明每一块咀嚼肌的功能。日本大耳白兔一侧咬肌注射A型肉毒毒素(BTXA)，制作咬肌功能抑制模型。BTXA注射的咬肌的厚度约为对照侧肌肉厚度的60%。并将肌电遥测系统植入兔体内。电极被插入咬肌和颞肌，递质被插入肩部皮下。

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.
