mu CT分析显示，1周后HD组的髁突宽度显著大于SD组。4周后，HSD组的下颌骨长度和升支高度显著大于其他两组。4周后，SD组的骨体积显著低于其他两组。提示咀嚼运动的改变对髁突软骨的生长和下颌骨形态有明显影响。人们认为，为了防止下颌骨发育中断，在幼年时进行饮食教育很重要。
mu CT analysis showed that the condylar width was significantly greater in the HD group than in the SD group after 1 week. After 4 weeks, mandibular length was significantly longer and ramus height was greater in the HSD group than in the other two groups. Bone volume was significantly less in the SD group than in the other two groups after 4 weeks. These findings suggest that changes in mastication markedly affect mandibular condylar cartilage growth and mandibular morphology. It is considered that dietary education at an early age is important in order to prevent disruption of the development of the mandible.
