Cov kev loj hlob ntawm zirconia ceramic thaiv
Mar 26, 2018| Cov kev loj hlob ntawm zirconia ceramic thaiv
Puas yog peb nrhiav tau cov porcelain uas muaj zog ntawm cov khoom siv los ua cov hlau?
Ib qho zoo ntawm ntau cov tuam txhab coj lawv tus kheej rau qhov no, thiab tau tsim thiab tso tawm qee cov khoom siv.Txawm li ntawd los, tsis yog lithium niobate porcelain, tiam sis tseem Alumina, cov khoom siv tes ua thiab cov khoom siv zog ntawm cov khoom tsuas yog tsim kho txhim kho ib los yog ob qho tib si. circumstance, zirconia uas muaj 10000Mpa tuaj rau peb pom.
Tsis tau muaj cov ntaub ntawv zoo li zirconia uas muaj laj lim tswv yim txhawb rau kev tsim kho cov tshuab fais fab. Peb muaj hmoo heev kom muaj peev xwm siv nws. Thiab nws nkawd hais tias tag nrho cov teeb meem yog smoothly daws tau.Ua zoo, muaj ntau cov hniav sib txuas ua ke, lub luv yog loj heev. Muaj tsis muaj cov khoom porcelain mus hloov nws thiab nws tau rivals lub hlau. Lub translucency ntawm lub zirconia cia cov hniav cuav tau txais qhov kev xa tawm ntawm cov hniav cov hniav.Thiab xim thiab kev ntxhib los mos yog lifelike.
Tus thawj coj ntawm Eberhard Karls Universität Tübingen, Martin Groten, said nyob rau hauv nws daim ntawv qhia hais tias raws li kev tshawb fawb ntawm German dental ceramic daim ntawv thov kev pab neeg, nyob rau hauv xyoo 2007, 2.7 lab ceramic cement tau ua.Qhov kev xyaum qhia tau hais tias zirconia zoo heev rau cov khoom siv ntawm cov kev siv cov txheej txheem siab.Cov ntaub ntawv zoo qhia tau hais tias cov zirconia porcelain muaj qhov tsis zoo ntawm kev defection zoo. Tom qab 10 xyoo kev pab, qhov kev qaug zog kuj yog tseem zoo nkauj heev.
Raws li ib yam khoom ntawm porcelain, zirconia yuav luag txhua qhov zoo ntawm cov khoom ua si khoom siv.Thiab nws yog siv los ua ceramic riam rau nws lub zog muaj zog thiab solidity.Nws tib lub sij hawm, raws li cov khoom kom ua joint protthesis, muaj tsis muaj chaw tsis txaus ntseeg tias nws muaj siab biocompatibility.Thaum kev sib xyaw nrog kev kho hniav kev lag luam, nthuav nws ntau nyob rau hauv daim ntawv thov ntawm cov hniav restoration.Tiam sis, lub siab zog (7.5) thiab high melting kub (2900 ℃) coj peb lo lus nug tshiab: yuav ua li cas rau nws?
Lub feature ntawm lub zirconia txiav txim tias tsis tuaj yeem ua tiav los ntawm tes los yog los ntawm cast.The precision ntawm cov hniav restoration thiab ib tus neeg kuj yog ib qho teeb meem rau cov procession.Yog li siv lub computer tswj cov cuab yeej xws li yog qhov tsuas daws ntawm qhov teeb meem .Yog li ntawd. los ntawm thawj hnub uas zirconia yog siv hauv kev kho hniav, nws yog indissolubly ua txhua yam nrog CAD CAM.
