项目摘要

X-ray TV (videofluorography) is useful apparatus for evaluating the function of mastication by the visual interpretation in the multiple phase of mastication using test food containing contrast medium. The purpose of this study is to clarify whether unilateral removable partial denture contribute to the function of shortened dental arch patients using this system. In this study unilateral shortened dental arch patients voluntarily cooperated.The results were as follows : 1. As a result of the visual analysis the volus formation trouble was observed. During chewing a part of food leaked through the defect of dental arch without denture. 2. The frequency of chewing increased without denture compared to with wearing denture. This showed that shortened dental arch patients without denture increased the frequency of chewing until swallowing. The condition of the dental arch might be inefficient for mastication.Shortened dental arch (SDA) concept started as one of the goals of treatment. It was the reason for SDA that the risk of wearing denture and sacrifice of comfort and little functional advantage. But these studies about analysis of mastication of SDA patients mainly focused on the crushing ability, and little focused on the volus formation and transportation ability.From the results of this study, it was thought that the dynamic evaluation of food control overall, for example volus formation and transportation, might be necessary to evaluate an appropriate function of mastication.

X射线电视（视频摄影）是使用含有对比介质的测试食物在咀嚼性多个阶段通过视觉解释来评估咀嚼功能的有用设备。这项研究的目的是阐明单方面可移除的部分义齿是否有助于使用该系统缩短牙科弓患者的功能。在这项研究中，单方面缩短的牙科弓患者自愿合作。结果如下：1。由于视觉分析，观察到了Volus形成故障。在咀嚼一部分食物的过程中，由于牙齿拱形的缺陷而没有义齿。 2。与穿着义齿相比，咀嚼的频率没有牙齿的频率。这表明，缩短了没有义齿的牙科拱门患者会增加咀嚼的频率，直到吞咽为止。牙齿拱门的状况可能效率低下。牙齿拱门（SDA）概念始于治疗的目标之一。 SDA的原因是，穿着义齿和牺牲舒适性和几乎没有功能优势的风险。但是，这些关于分析SDA患者咀嚼的研究主要集中在粉碎能力上，几乎没有集中于沃尔斯的形成和运输能力。从这项研究的结果，人们认为对食物控制的动态评估总体上，例如Volus，例如Volus形成和运输对于评估适当的咀嚼功能可能是必要的。
