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，对选择性咀嚼肌进行抑制，并对各咀嚼肌进行详细分析，阐明各咀嚼肌的功能。用A型肉毒毒素（BTXA）注射日本大耳白兔一侧咬肌，制作咬肌功能抑制模型。注射BTXA的咬肌厚度约为对照侧咬肌厚度的60%。并将肌电遥测系统植入家兔体内。电极插入咬肌和颞肌，发射器插入肩部皮下。

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.
