陶瓷材料在人假牙中的力学性能研究

成都学院学士学位论文（设计）陶瓷材料在人假牙中的力学性能研究专业：材料成型及控制工程学号：学生：指导老师：摘要：目的：陶瓷材料是牙齿缺损修复中应用最广泛的材料之一，但陶瓷材料的脆性和低的强度限制了其临床应用范围及使用可靠性，本研究利用三维光学扫描仪和计算机三维设计软件对陶瓷假牙进行力学性能的分析，寻求提高其韧性和强度，推广陶瓷材料的临床应用范围。方法：采用氧化锆陶瓷材料，利用三维光学扫描仪对正常人第一磨牙进行数据采集，GeomagicStudio11软件进行数据处理，计算机三维设计软件CATIAV5重构三维实体模型，Solidworks2010软件建立有限元分析模型，在此基础上分析陶瓷磨牙和树脂磨牙的力学性能。将分析结果进行对比，并与正常人下颌第一磨牙进行比较。结果：建立的模型可进行准确的力学分析，能有效的将氧化锆全瓷假牙与正常人磨牙及树脂假牙进行对比。结论：利用三维光学扫描仪和三维设计软件可以很好的分析陶瓷假牙的力学性能，为提高其强度和韧性提供了基础。关键字：陶瓷材料；三维光学扫描仪；力学性能；三维设计软件成都学院学士学位论文（设计）Mechanicalpropertiesstudyofceramicmaterialsfromhuman’sdentureSpecialty:MaterialFormingandControllingEngineeringStudentNumber:200910112202Student:YangYaoSupervisor:DongZhihongAbstact：Objective：Ceramicmaterialsareoneofthemostwidelyusedmaterialfordentaldefectrepairing，butbrittlenessandlowerstrengthlimititsapplicationrangeandreliabilityinclinic.Theresearchusingthree-dimensionalopticalscannerandcomputer3Ddesignsoftwaretoanalyzethemechanicalpropertiesofceramicdentureteeth，seekingtoimproveitstoughnessandstrengthandextendingitsclinicalapplicationofceramicmaterials.Method：ZrO2ceramicmaterialwasusedtocollectdataofnormalpeople’sfirstmolarbythree-dimensionalopticalscannerandtomanagedatabyGeomagicStudio11softwareandtoreconsitutes3Dsolidmodelbycomputer3DdesignsoftwareCATIAV5.Solidworks2010softwarebuiltthefiniteelementanalysismodelinordertoanalyzemechanicalpropertiesofceramicmolarandresinteeth.Andbythesimulationresults，comparedwithfirstmolaroflowerjawfromnormalhuman.Result：Theestablishedmodelcanaccuratelyanalyzethemechanicalproperties，andcaneffectivelycompareZrO2all-ceramicteethandnormalhumanmolarsandresindenture.Conclusion：Usingthe3Dopticalscannerand3Ddesignsoftwarecaneffectivelyanalyzemechanicalpropertiesofceramicdentureteethandprovidethebasisforimprovingthestrengthandtoughness.KeyWords:Ceramicmaterial；3Dopticalscanner；Mechanicalpropertie；3Ddesignsoftware成都学院学士学位论文（设计）I目录第一章绪论............................................................................................................................................11.1陶瓷材料在口腔修复领域中的的发展与前景........................................................................11.2陶瓷假牙力学性能的研究现状................................................................................................21.3本课题的选题背景与工作内容................................................................................................31.3.1选题背景.........................................................................................................................31.3.2工作内容.........................................................................................................................3第二章磨牙三维模型的建立................................................................................................................42.1材料与设备................................................................................................................................42.2下颌第一磨牙的制备...............................................................................................................42.3.三维光学扫描仪原理................................................................................................................52.4三维扫描前期准备....................................................................................................................52.4.2系统的标定......................................................................................................................62.4.3下颌第一磨牙的处理......................................................................................................62.5三维扫描过程............................................................................................................................62.5.1调整下颌第一磨牙的位置..............................................................................................62.5.2扫描下颌第一磨牙..........................................................................................................62.5.3导出云点图......................................................................................................................72.6云点数据处理............................................................................................................................72.6.1云点处理软件的特点......................................................................................................72.6.2云点处理的过程..............................................................................................................82.7曲面形成....................................................................................................................................92.8重构三维实体模型..................................................................................................................102.9本章小结..................................................................................................................................11第三章力学性能分析..........................................................................................................................123.1应力分析软件的特点.............................................................................................................1
