Yuav ua li cas kho zirconia crowns
Nov 30, 2018| 
Zirconia restorations yog cov khoom siv kho kom zoo tshaj plaws, muab kev sib xyaw ua ke ntawm lub zog, durability, biocompatibility thiab esthetics. Zirconia yog ib qho nyuaj thiab muaj zog dua li cov hlau feem ntau siv rau cov txheej txheem yas thiab choj. Yog li ntawd, nws tuaj yeem nyuaj tshwj xeeb los kho kom haum nrog kev ntsuas ntsuas.
Rau cov txiaj ntsig zoo tshaj plaws thaum ua haujlwm nrog zirconia, koj yuav tsum tso siab rau cov cuab yeej ua kom zoo rau cov khoom siv muaj zog. Cov cuab yeej txheem feem ntau ua tsis tiav hauv cov xwm txheej no, xav kom tus neeg teb xov tooj siv ntau lub burs los kho lossis polish ib qho kev kho dua tshiab. Nyob rau hauv lem, yog hais tias tus instrumentation tsis ua tiav ib tug siab luster nyob rau hauv lub restoration, lub zirconia yuav heev unforgiving thiab antagonistic rau cov opposing hniav; Yog li ntawd, cov khoom siv tshwj xeeb tshwj xeeb rau siab-lub zog ceramics muab cov kev daws teeb meem zoo tshaj plaws. Cov khoom siv muaj ntau yam cuab yeej tshwj xeeb tsim los txiav, ua kom tiav thiab polish tag nrho-contour restorations fabricated ntawm zirconium oxide, lithium disilicate, aluminium oxide thiab lwm yam pressed ceramics.
Txhawm rau rov ua kom pom, kho lossis ua tiav lub zirconia crown, siv cov pob zeb diamond bury uas yog tsim tshwj xeeb nrog kev sib koom ua ke mus tas li, ntim pob zeb diamond txheej. Cov pob zeb ntxhib-grit muab qhov tshwj xeeb rau kev ua haujlwm-rau-kev pabcuam lub neej piv, thiab cov qauv nruab nrab-grit tshwj xeeb yog tsim rau ntau yam kev hloov kho.
Kho occlusal contacts kuj tseem xav tau ntau zaus thaum lub sijhawm sim thiab / lossis tom qab tso. Yog tias muaj kev hloov kho me me occlusal xav tau, tsuas yog siv cov roj hmab abrasive polishing log thiab tsis yog pob zeb diamond. Lub pob zeb diamond tsuas yog xav tau yog tias muaj kev hloov pauv tseem ceeb yuav tsum tau ua. Yog tias lub pob zeb diamond siv rau hauv cov txheej txheem no, kev polishing kom zoo yog qhov tsim nyog kom ua tiav qhov chaw du. Lub polished ceramic nto yog abrasive tsawg dua li ib qho uas yog glazed, yog li yuav tsum tsis muaj qhov yuav tsum tau rov qab glazing ntawm kev kho dua tshiab Qhov loj ntawm txoj kab uas hla ntawm polishing log siv, ntau npaum li cas thiab cov txheej txheem. Ib qho tseem ceeb yuav tsum tau nkag mus rau hauv qhov tob ntawm lub cev, txawm li cas los xij nws yog qhov ua tau zoo tshaj plaws vim nws qhov loj me.
