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（荧光显像）是一种评价咀嚼功能的有用仪器，利用含有造影剂的试验食品，通过视觉解释来评价咀嚼的多阶段功能。本研究的目的是阐明单侧可摘局部义齿是否有助于使用该系统的短弓患者的功能。在本研究中，单侧缩短牙弓患者自愿配合。实验结果如下：1.实验结果表明：目视分析的结果是观察到体积形成问题。咀嚼过程中，部分食物通过无义齿牙弓缺损渗漏。2. 不戴假牙的咀嚼次数比戴假牙的咀嚼次数增加。结果表明，无假牙的短弓患者咀嚼次数增加，直至吞咽。牙弓的状况可能不利于咀嚼。缩短牙弓（SDA）的概念是作为治疗的目标之一而开始的。采用SDA的原因是由于佩戴义齿存在风险，牺牲了义齿的舒适性，而且功能优势很小。但这些关于SDA患者咀嚼功能分析的研究主要集中在咬碎能力方面，而对体积形成和运输能力的研究较少。从本研究的结果来看，可能有必要对食物控制的整体动态评估，例如体积的形成和运输，以评估咀嚼的适当功能。
