正常(牙合)的建立有赖于牙齿的正常发育、正常萌出与正常功能,而牙齿的正常萌出与功能又与牙齿周围软组织产生的压力有密切关系。早在19世纪,人们就认为唇颊舌肌肉活动产生的力可能影响牙齿的位置与牙弓的形态。基于此观点,许多学者观察分析了软组织功能与硬组织形态之间的关系,肯定了肌肉压力对牙弓形态的作用,提出了牙弓内外唇颊舌肌肉压力平衡及唇颊舌肌压力决定牙弓形态的假
Normal occlusion depends on the normal development of teeth, normal eruption and normal function, while the normal eruption and function of teeth are closely related to the pressure generated by soft tissue around the tooth. As early as the 19th century, people think that the force generated by the labial buccal muscles may affect the position of the teeth and the shape of the dental arch. Based on this view, many scholars observed and analyzed the relationship between soft tissue function and hard tissue morphology, affirmed the effect of muscle pressure on dental arch morphology, put forward the pressure balance between buccal and lingual muscles of the dental arch and lip buccal muscle pressure, Bow shape of the fake
