Simulation in 3D-model of skeletal forms of sagittal malocclusion revealed tendency in tonus' modification of muscles of mastication in formation of distal and mesial occlusion. It's shown that distal occlusion is characterized by hypotonic condition of muscles of mastication, except posterior fibers of temporal muscle. Mesial occlusion is characterized by complex combination of muscle tone with prevalence of hypotonic condition of anterior fibers of temporal muscle, superficial portion of masseter muscle and medial pterygoid muscle. We have detected that using of myofunctional devices in treatment of sagittal malocclusion, temporomandibular joint dysfunction promotes of tone increasing of muscles of mastication.
矢状错颌骨骼形态三维模型的模拟显示，在远中及近中咬合形成过程中，咀嚼肌紧张度有改变的趋势。结果表明，除颞肌后纤维外，远中咬合的特征是咀嚼肌张力减退。近中咬合的特征是肌张力的复杂组合，以颞肌前纤维、咬肌浅层和翼内肌张力减退为主。我们发现，在矢状错颌、颞下颌关节功能紊乱的治疗中使用肌功能矫治器可促进咀嚼肌张力增加。
