烧结次数对CAD/CAM可切削陶瓷修复体性能的影响吴岩珠刘茜*河北医科大学第三医院口腔修复科河北石家庄050000[摘要]作为一种新兴的口腔修复技术,计算机辅助设计和计算机辅助制作(computeraideddesignandcomputeraidedmanufacture,CAD/CAM)因其高效、精确的优点,近年来被广泛应用于临床。尽管该修复技术拥有较高的临床成功率,其临床效果还是会受多种因素的影响。除机械和美学等自身性能因素外,材料的加工工艺也会影响其成功率。在加工生产过程中,不同环节会对修复体的性能产生不同程度的影响。临床实践中医生常常会因为改色、邻接等问题增加烧结次数,这使得切削后烧结成为关注点之一。本文针对烧结次数对CAD/CAM可切削材料修复体性能的影响做一综述,以期对技工及临床工作有所帮助。[关键词]计算机辅助设计和计算机辅助制作;陶瓷;烧结次数;性能[文献标识码]A[文章编号]1671—7651(2023)06—0483—04[doi]10.13701/j.cnki.kqyxyj.2023.06.003EffectsofSinteringTimesonPropertiesofCAD/CAMMachinableCeramicRestorations.WUYanzhu,LIUQian*.DepartmentofProsthodontics,TheThirdHospitalofHebeiMedicalUniversity,Shijiazhuang050000,China.[Abstract]Duetoitshighefficiencyandaccuracy,CAD/CAM,asanoveldentalrestorationtechnology,hasbeenwidelyappliedinclinics.Althoughthisrestorationtechniqueexhibitshighsuccessrate,theresultscouldstillbeaf-fectedbyseveralfactors,suchasmechanicalandaestheticproperties.Inaddition,thesuccessratecouldalsobein-fluencedbytheprocessingtechniqueofmaterials.Intheproductionprocess,differentstepsmayaffecttherestora-tionperformancetovariousdegrees.Inclinicalpractice,thenumberofsinteringmaybechangedfromcasetocaseforthepurposeofcolorchangeandadjacencycontact,whichcausesthepost-cuttingsinteringtobeasignificantcon-cern.Inthispaper,anextensiveandcomprehensivereviewisconductedontheeffectsofsinteringtimesontheCAD/CAMmachinablematerialrestorationtosummarizeusefulinformationtodentaltechniciansaswellasclinicalwork.[Keywords]computeraideddesignandcomputeraidedmanufacture;ceramic;sinteringtimes;performance计算机辅助设计和计算机辅助制作(computeraidedde-signandcomputeraidedmanufacture,CAD/CAM)作为一种新兴口腔修复技术具有修复体精度高、修复周期短等优点,...
