Young Children Mandibular Movement Recording Apparatus Chewing E.M.G.Stomatognathic System Clinical Examination

项目摘要

In Pedodontic clinic,the aim is to bring about the normal growth of dentition. There has been an increasing need for comprehensive examination and diagnosis for child patient that are based on the functional apset of information in addition to the morphological one. For adult patients, the examination on the mandibular movement or the chewing efficiency has been already practiced,but for child patients, especially younger patients with deciduous dentition, it has been so much burden to them, against their mental and physical condition, to apply the apparatus for adults to children that we can not obtain any correct data concerning children. So the invention of apparatus and the establishment of clinical examination system for young child patient has long been desired.Our project team started inventing the apparatus for young children,which can be used after 3 years of age, and have efforted to make the original apparatus and improved it many times. Now, we have been able to complete the apparatus carrying out our purpose,and to analyze the mandibular movement of normal children with deciduous dentition, and, moreover, also to diagnose child patients functionally before and after treatment who have anomalies about their dentition,interocclusal relation and temporomandibular joint. We are also able to record and to analyze the electromyogrm of masticatory muscles, and now, we could establish the examination system of stomatognathic function of young children. There are many problems concerning the system yet, but we have obtained a large amount of information beyond expectation as to the clinical examination and diagnosis of young child patients.

在儿科临床中，其目的是使牙列正常发育。越来越需要对儿童患者进行全面的检查和诊断，这些检查和诊断除了基于形态信息外，还基于功能信息集。对于成人患者，已经进行了下颌运动或咀嚼效率的检查，但对于儿童患者，特别是年龄较小的乳牙期患者，针对他们的心理和身体状况，将成人设备应用于儿童，我们无法获得任何关于儿童的正确数据。因此，发明婴幼儿仪器和建立幼儿临床检查系统一直是人们渴望的事情。我们项目组开始发明3岁以后可以使用的婴幼儿仪器，并努力制作了原来的仪器，并对其进行了多次改进。现在，我们已经能够完成我们的目的的仪器，分析正常的乳牙期儿童的下颌运动，并对治疗前后有牙列异常、咬合关系异常和颞下颌关节异常的儿童患者进行功能性诊断。我们还可以记录和分析咀嚼肌的肌电，现在我们可以建立幼儿口腔颌面功能的检测系统。该系统还存在许多问题，但我们在幼儿患者的临床检查和诊断方面获得了大量意想不到的信息。
