Hauv kev ua haujlwm txhua hnub rau cov kws kho hniav thiab cov chaw kho mob txawv teb chaws, peb pom cov lus nug qub tuaj dua: qhov kev xaiv zirconia yuav ua tau tiag tiag hauv lub qhov ncauj - siab translucent zirconia lossis txheej zirconia? Ob qho khoom siv tseem ceeb niaj hnub CAD / CAM kho dua tshiab, tab sis lawv daws teeb meem sib txawv. Ib qho tseem ceeb ntawm kev ua tau zoo thiab kev ntseeg siab. Lwm qhov tseem ceeb tshaj plaws kev hloov kho ntawm tus nqi ntawm cov kauj ruam ntxiv thiab kev pheej hmoo.
Peb tau milled ntau txhiab units ntawm txhua hom. Ntawm no yog ib qho kev sib cais ncaj qha raws li qhov tshwm sim tiag tiag hauv kev tsim khoom thiab hauv kev tawm tswv yim kho mob.
Dab tsi yog High Translucent Zirconia?
High translucent zirconia, feem ntau sau npe HT zirconia lossis 5Y zirconia, hais txog monolithic lossis multilayer blocks nrog cov ntsiab lus yttria siab dua (feem ntau 4-5 mol% lossis ntau dua). Qhov no hloov ntau lub sij hawm siv lead ua mus rau cubic zirconia, uas cia lub teeb hla tau yooj yim dua.
Ntawm 1 hli thickness, cov ntaub ntawv no feem ntau ua tiav lub teeb kis tau tus mob siab tshaj 40%, qee zaum ncav cuag 43-57% hauv gradient multilayer versions. Flexural zog feem ntau tsaws nyob rau hauv 600-900 MPa ntau yam rau 5Y hom, txawm hais tias multilayer tsim kom muaj zog dua nyob rau hauv lub ncauj tsev menyuam / hauv paus cheeb tsam (txog 900-1200 MPa nyob rau hauv ib co gradient blocks) thaum nyob ntau translucent incisally.
Qhov txiaj ntsig zoo tshaj plaws yog kev ua haujlwm. Koj mills tag nrho contour los ntawm ib qho thaiv los yog ua ntej - txheej disc. Tsawg kawg phau ntawv staining los yog tsis muaj plooj (porcelain buildup) xav tau nyob rau hauv ntau zaus. Qhov no txiav lub sij hawm ntau lawm thiab tshem tawm cov interface uas tej yam yuav ua tsis tau tom qab.
Niaj hnub nimno multilayer siab translucent zirconia txhim kho nyob rau hauv cov niaj hnub niaj hnub versions los ntawm lub tsev nyob rau hauv cov xim thiab translucency gradients uas zoo dua mimic dentin-rau-enamel hloov. Qhov ntawd ua rau nws siv tau rau cov rooj plaub sab hauv ntau dua li cov qub monolithic blocks puas tau.
Txheej Zirconia yog dab tsi?
Txheej zirconia pib nrog lub siab - lub zog zirconia core, feem ntau 3Y-TZP. Cov tub ntxhais no muab lub zog flexural nyob rau hauv 1100-1500 MPa ntau yam thiab zoo heev tawg toughness. Cov kws kho mob tom qab ntawd siv thiab tua hluav taws porcelain veneer txheej rau saum toj los tsim cov duab kawg, xim, thiab cov teebmeem saum npoo.
Lub zirconia substructure nqa lub load. Cov plooj (porcelain) ua haujlwm feem ntau ntawm qhov pom kev zoo nkauj - opalescence, characterization, thiab xim zoo sib xws. Qhov kev tsim kho no muab cov kev hloov kho siab tshaj plaws vim tias tus kws kho mob tuaj yeem kho txhua yam ntawm tes lossis nrog kev txiav - rov qab cov txheej txheem.
Kev lag luam tawm - tawm yog pom tseeb hauv chav kuaj: ntau cov kauj ruam, ntau lub voj voog hluav taws xob, thiab qhov cuam tshuam ntawm zirconia thiab plooj (porcelain) uas tuaj yeem dhau los ua qhov tsis muaj zog hauv kev ntxhov siab lossis kev txhawb nqa tsis zoo.
Qhov sib txawv tseem ceeb ntawm High Translucent Zirconia thiab Txheej Zirconia
Qhov kev txiav txim siab tiag tiag feem ntau yog los ntawm peb yam: ntau npaum li cas lub teeb koj xav tau, ntau npaum li cas quab yuam kev kho dua tshiab yuav tsum tau ua, thiab ntau npaum li cas lub sij hawm thiab kev pheej hmoo koj xav kom txais hauv fabrication.
Nov yog qhov sib piv ncaj qha ntawm qhov tseem ceeb tsis peb taug qab hauv kev tsim khoom:

High -esthetic anterior lossis complex case |
High translucent versions, tshwj xeeb tshaj yog multilayer blocks, tau nqaim qhov esthetic sib txawv ho. Yav dhau los monolithic zirconia feem ntau ntsia tiaj tus los yog "dub" nyob rau hauv lub luag nyav cheeb tsam. Tam sim no gradient discs txo qhov teeb meem los ntawm kev sib txawv ntawm cov ntsiab lus yttria thiab ntxoov ntxoo los ntawm tuab.
Layered zirconia tseem yeej thaum ib rooj plaub xav tau tus cwj pwm ntawm tus kheej uas tsis muaj pre- txheej thaiv tuaj yeem rov ua dua. Tab sis qhov ntawd los nrog qhov tseeb ntawm kev tswj cov plooj (porcelain) txhawb nqa thiab tua.
Anterior vs Posterior: Qhov twg Txhua yam khoom ua tau zoo tshaj plaws
Kev kho sab nrauv (Incisors, Canines, Premolars - Smile Zone)
Lub teeb kis tau tus mob tseem ceeb tshaj ntawm no. Cov neeg mob pom qhov sib txawv me ntsis ntawm qhov sib txawv ntawm cov yas sib xyaw nrog cov hniav ntuj nyob rau hauv cov teeb pom kev sib txawv.
Multilayer siab translucent zirconia ua haujlwm zoo rau ntau lub anterior crowns thiab luv choj. Cov ua - nyob rau hauv gradient tuav lub ncauj tsev menyuam opacity thiab incisal translucency yam tsis muaj zog ntxiv. Chiping kev pheej hmoo nyob qis vim tias tsis muaj veneer txheej los delaminate.
Layered zirconia tseem yog qhov kev xaiv thaum tus kws kho hniav lossis tus neeg mob xav tau qhov siab tshaj plaws ntawm kev hloov kho - tshwj xeeb opalescence, mamelons, lossis tus cwj pwm tshwj xeeb uas phim cov hniav uas nyob ib sab zoo kawg nkaus. Lub sijhawm ntxiv thiab tus nqi tsuas yog ua rau kev txiav txim siab thaum esthetics tsav tag nrho cov ntaub ntawv.
Hauv peb qhov kev paub dhau los, niaj hnub multilayer HT zirconia tam sim no npog feem ntau ntawm kev ua haujlwm anterior yam tsis muaj kev cuam tshuam rau lub zog rau lub teeb occlusion zones.
Tom qab Restorations (Molars, Choj, Bruxers)
Occlusal rog txiav txim siab cov khoom ntawm no. Hnyav tom loads thiab parafunction rau txim rau cov ntsiab lus tsis muaj zog.
Lub siab - lub zog 3Y core hauv txheej zirconia tuav hnyav occlusion ntseeg tau, tab sis cov plooj (porcelain veneer) tseem muaj feem cuam tshuam yog tias kev txhawb nqa yog marginal lossis yog tias tus neeg mob grinds hnyav.
High translucent monolithic lossis multilayer zirconia txo qhov kev pheej hmoo loj vim tias tag nrho cov kev kho dua tshiab yog tib yam khoom tawv. Lub zog yog qis dua 3Y core, tab sis rau feem ntau tom qab ib lub kaus mom thiab ntau cov txuas hniav nws tseem muaj ntau tshaj qhov tsim nyog, tshwj xeeb tshaj yog nrog cov tuab tuab. Multilayer tsim ua kom zoo translucency thaum tiv thaiv lub hauv paus.
Rau cov bruxers hnyav lossis ntev - ncua txuas txuas, peb feem ntau ua rau siab dua - lub zog monolithic xaiv los yog ua tib zoo tsim txheej txheej nrog kev txhawb nqa zoo.
