Relationship between oral soft tissue and craniofacial morphology to the function of feeding and deglutition

为了研究整个咀嚼阶段，本研究对咀嚼的各个阶段进行了调查。结果表明，骨骼ⅰ类和骨骼ⅱ类受试者在吞咽前将花生捣碎，咀嚼次数增加，而骨骼ⅲ类受试者咀嚼时间短，咀嚼次数少，花生捣碎不够。正常咬合组按咀嚼20次将花生捣碎。

In order to study the entire mastication stage, the present study investigated all stage of mastication. The results suggested that subjects with skeletal Class I and II groups mashed the peanuts by just before swallowing by the increase in the number of times in mastication, while subjects with skeletal Class III group did not mashed sufficiently the peanuts with the short duration of mastication and the small number of times in mastication. Normal occlusion group mashed the peanut by the 20 timesof mastication.
