CAD/CAM全瓷冠在后牙种植体修复中的应用3汪振华33,王建青(乌鲁木齐市口腔医院修复科,新疆乌鲁木齐830000)摘要:目的:对采用CAD/CAM与传统方法制作后牙种植体冠的修复效果进行回顾性调查,评价不同制作方法的临床效果,以探讨更有利于种植体修复的全瓷修复技术。方法:选取采用CAD/CAM方法制作全瓷冠修复的种植体病例30例作为实验组,采用传统方法制作32例作为对照组,修复6个月后复查,填写修复体满意度调查表,依照改良的USPHS标准对修复体进行评价。结果:在费用方面,实验组患者的满意度为33%,对照组为78%;在就诊时间和次数上实验组患者的满意度为100%,对照组为63%;在外形方面实验组明显优于对照组(P<0.05);而在边缘适合性、表面质地及颜色匹配3方面2组差异无统计学意义(P>0.05)。结论:CAD/CAM系统操作简便,制作修复体快捷且外形美观,与传统方法相比更有利于种植体的修复。关键词:种植体;CAD/CAM;全瓷冠中图分类号:R781.05;R783文献标识码:A文章编号:100925551(2007)1121249203TheapplicationofCAD/CAMallceramiccrownintheposteriorteeth′simplantWANGZhen2hua,WANGJian2qing(DepartmentofProsthetics,UrumqiStomatologyHospital,Urumqi830000,China)Abstract:Objective:Toevaluatetheclinicaleffectivenessoftheallceramiccrownintheposteriorteeth′simplantmanufacturingwithCAD/CAMandclassicmethod.Andtodiscusswhichwasthebetterallce2ramicrestoration′stechniquetotheimplant.Methods:Sixty2tworestorationswereinvolvedinthestudy.Thefabricationtimewasrecordedandsatisfactoryformwasfilledbypatientoneweekaftertreatment.TherestorationqualitywasevaluatedusingmodifiedUSPHSstandardaftersixmonths.Results:Inthedirec2tionofcost,thepatients′satisfactoryformtoCAD/CAMwas33%,thecontrolgroupwas78%.Inthedirectionofvisitingtimeandfrequence,CAD/CAMwas100%,thecontrolgroupwas63%.Twogroupshadstatisticalvariationinthedirectionofcontour(P<0.05),butnotinthedirectionsofcervicalmargin′sdenseandfitnature,colormatchingandsurfacetexture(P>0.05).Conclusions:CAD/CAMsystemof2ferseasyandquickmanufactoryofrestorations,andbettertotheimplantthanclassicmethod.Keywords:implant;CAD/CAM;allceramiccrown牙种植术被称为是20世纪牙科史上最令人瞩目的一大进展,也是近年口腔医学领域中发展速度最快的一项技术。在西方发达...
