Dab tsi yog Feldspathic Veneer? Cov txiaj ntsig, txheej txheem, thiab thaum twg los xaiv

Lub feldspathic veneer yog ib qho ultra-thin porcelain veneer ua los ntawm feldspathic ceramic, feem ntau yog siv hauv kev kho kom zoo nkauj sab hauv. Nws yog feem ntau fabricated los ntawm ib txhais tes - txheej txheej txheej es tsis nias los yog milling, uas tso cai rau meej tswj ntawm translucency, ntxoov ntxoo, thiab nto nthuav dav.

Hauv cov ntsiab lus kho mob, feldspathic veneers raug xaiv thaum qhov tseem ceeb tshaj plaws yog rov ua cov hniav zoo nkauj kom ze li sai tau, tsis yog ua kom muaj zog.

Dab tsi yog Feldspathic Veneer? Thiab Nws Ua Li Cas?

A feldspathic veneeryog lub plhaub nyias nyias, feem ntau 0.3-0.7 hli tuab, sib txuas rau lub ntsej muag ntawm tus hniav kom txhim kho kev zoo nkauj. Nws yog tsim los ntawm tes- txheej txheej porcelain hmoov thiab kua rau ntawm lub refractory tuag los yog platinum ntawv ci, ces firing ntau zaus nyob rau hauv lub qhov cub porcelain.

Cov khoom siv hauv paus yog feldspar porcelain- feem ntau hauv av feldspar (potassium feldspar KAlSi₃O₈ los yog sodium feldspar NaAlSi₃O₈), ua ke nrog quartz, kaolin, thiab lwm yam fluxes. Tom qab tua hluav taws, cov qauv ua ib lub iav matrix nrog me me ntawm leucite crystals. Cov ntsiab lus iav siab no muab cov khoom siv nws qhov tshwj xeeb translucency, opalescence, thiab fluorescence, ze ze replicating ntuj enamel optics.

Tsis zoo li lithium disilicate (e.max), uas tso siab rau lub crystalline reinforcement rau lub zog, feldspathic porcelain nyob ntawm yuav luag tag nrho ntawm nws cov iav iav. Tias yog vim li cas nws kis lub teeb li ib txwm muaj tab sis kuj yog vim li cas nws yuav tsum tau ceev faj xaiv cov ntaub ntawv.

Hauv kev xyaum, qhov kev sib xyaw no tso cai rau cov kws tshaj lij los tsim cov teebmeem dentin me me, incisal halos, thiab txheej txheej zoo nkauj los ntawm txheej -qee yam CAD/CAM blocks tawm tsam kom rov tsim dua ntawm tib theem ntawm kev nthuav dav.

Qhov zoo ntawm Feldspathic Veneers

Peb pom cov kws kho mob xaiv feldspathic thaum esthetics trump txhua yam ntxiv. Nov yog cov txiaj ntsig zoo uas peb pom hauv kev tsim khoom txhua hnub:

• Siab tshaj translucency thiab optical mimicry ntawm cov hniav ntuj. Lub teeb hla dhau thiab xav txog txoj hauv kev uas xav tias muaj sia nyob, tshwj xeeb tshaj yog nyob rau hauv cov ntu nyias.
• Tsawg lossis tsis muaj kev npaj cov hniav hauv ntau qhov xwm txheej. Peb niaj hnub tsim 0.3-0.4 hli veneers rau additives -tsuas yog txoj hauv kev.
• Superior xim txuam thiab characterization. Tes-txheej txheej cia cov ceramist zoo-hloov xim, chroma, tus nqi, thiab cov teebmeem sab hauv kom sib txuas nrog cov hniav uas nyob ib sab.
• Yooj yim rau kev tawm tsam kev kho hniav. Cov ntaub ntawv hnav zoo ib yam li cov enamel, txo qhov ntev - lub sij hawm puas tsuaj piv rau cov ceramics nyuaj.
• Cov ntaub ntawv pov thawj hauv anterior esthetics. Kev tshawb fawb soj ntsuam qhiaciaj sia nyob ib ncig ntawm89-96% ntawm 9-10 xyoothaum sib raug zoo rau enamel.

Cov ntsiab lus no tuav tau zoo tshaj plaws nyob rau hauv qis -kev ntxhov siab anterior daim ntawv thov qhov twg tus neeg mob muaj qhov zoo occlusion thiab tsis hnyav parafunction.

Kev txwv ntawm Feldspathic Veneers

Tsis muaj cov khoom zoo meej. Feldspathic plooj (porcelain) muaj cov yam ntxwv meej meej.

• Flexural zog zaum ntawm 60-90 MPa. Qhov ntawd ua rau nws yooj yim rau chipping los yog tawg nyob rau hauv hnyav occlusal load, bruxism, los yog ntug - mus rau - ntug tom.
• Tsis zoo tagnrho rau hnyav discoloration. Cov txheej nyias nyias muaj qhov txwv tsis pub, yog li qhov hnyav tetracycline staining lossis tsaus preps feem ntau xav tau ntau lub npog ntsej muag.
• Cov txheej txheem-sensitive. Kev vam meej nyob ntawm qhov kev txawj ntse ntawm ceramist, cov txheej txheem meej, thiab tswj kev tua hluav taws. Cov kev sim tsis sib xws ua rau cov txiaj ntsig tsis sib xws.
• Kev pheej hmoo siab dua ntawm kev teeb meem kev siv sijhawm. Ntev - cov ntaub ntawv lub sij hawm qhia tau hais tias chipping thiab tawg tus nqi siab dua lithium disilicate.

Hauv peb qhov kev paub dhau los, cov kev txwv no dhau los ua teeb meem feem ntau yog thaum kev kho dua tshiab tau muab tso rau sab nraum nws qhov chaw zoo tshaj -cov hniav tom qab, kev ua haujlwm hnyav, lossis cov neeg mob uas clench hnyav.

Feldspathic Veneers vs E.max: Qhov txawv yog dab tsi?

Cov kws kho mob feem ntau hais kom peb sib piv ob. Qhov kev txiav txim siab feem ntau yog los rau esthetics piv rau durability.

Ntawm no yog ib sab ncaj nraim -los ntawm- sab:

Feldspathic yeej thaum lub hom phiaj yog qhov txiaj ntsig zoo tshaj plaws nrog kev npaj ua ntej. E.max yuav siv sij hawm thaum rooj plaub yuav tsum muaj zog ntau dua los yog npog cov substrates tsaus.

Thaum twg Koj Yuav Tsum Xaiv Feldspathic Veneers?

Peb pom zoo feldspathic hauv cov xwm txheej no:

• Cov hniav sab nrauv xav tau cov duab, qhov ntev, lossis kev kho me me uas tsis muaj qhov hnyav.
• Cov xwm txheej uas qhov siab tshaj plaws translucency yog qhov tseem ceeb- cov neeg mob hluas, cov kab luag nyav siab, nyias gingiva.
• Tsawg heev -prep lossis tsis muaj-prep luag ntxhi makeovers qhov uas khaws cov enamel tsis yog- sib tham.
• Cov neeg mob uas ib txwm occlusion thiab tsis muaj qhov tseem ceeb parafunction.

Zam nws rau tom qab kho dua tshiab, bruxism hnyav, sib sib zog nqus xim uas yuav tsum tau muaj qhov pom tseeb, lossis thaum tus neeg mob muaj ntug - mus rau - ntug incisal tiv tauj yam tsis muaj kev taw qhia.

Nyob rau hauv cov xwm txheej ciam teb, qee zaum peb hais qhia ib qho kev sib xyaw: feldspathic layering hla e.max core rau ntxiv zog yam tsis muaj kev txi ntau dhau esthetics.

Yuav Ua Li Cas Feldspathic Veneers?

Cov txheej txheem yog kev ua haujlwm- hnyav thiab kev txawj ntse- nyob ntawm - yog vim li cas qhov zoo sib txawv ntawm cov chaw sim.

1. Qauv thiab kev npaj tuag - Tsim kom muaj qhov tuag refractory (los yog siv cov ntawv ci platinum) los ntawm tus tswv cam khwb cia kom tiv taus hluav taws xob shrinkage.
2. Txheej - Sib tov cov hmoov plooj (porcelain) nrog kua. Cov ceramist siv cov txheej nyias nyias: opaque dentin lub cev ua ntej, tom qab ntawd cov teebmeem incisal, mamelons, halo, thiab qhov chaw zoo nkauj. Txhua txheej yog raug rho tawm haujlwm cais los tswj qhov shrinkage thiab tsim qhov tob.
3. Kev tua ntau yam - Feem ntau 5-8 lub voj voog ntawm 900-950℃. Txhua qhov hluav taws xob fuses txheej txheej thiab tso cai rau kom zoo contouring.
4. Tiav - Txiav rov qab, ntxiv cov stains extrinsic yog xav tau, glaze, thiab polish rau ntuj luster.

Cov kev ua haujlwm niaj hnub no muab cov qauv tsim digital rau daim ntawv raug nrog tes- txheej txheej rau tus cwj pwm. Ntawm ADS, peb siv 3D- cov qauv luam tawm thiab cov qauv digital-ups los coj tus kws kho mob, tab sis cov txiaj ntsig zoo nkauj tseem yog los ntawm phau ntawv tsim.

Qhov no tsis yog ceev ntau lawm. Nws yuav siv sij hawm vim shortcuts cuam tshuam qhov kev tshwm sim ntawm optical.

Yuav Ua Li Cas Xaiv Lub Chaw Kho Hniav Kho Hniav rau Veneers?

Thaum outsourcing veneers-tshwj xeeb tshaj yog feldspathic- tsom rau cov ntsiab lus no:

• Kev ua pov thawj nrog tes- txheej feldspathic. Nug cov duab tsis ntev los no uas qhia txog kev sib xyaw ua ke thiab cov teebmeem incisal.
• Clear kev sib txuas lus raws tu qauv. Cov duab ntxoov ntxoo nthuav dav, cov duab hauv qab lub teeb sib txawv, thiab cov lus tawm tswv yim ceev nrawm txo cov remakes.
• Kev tswj xyuas zoo ntawm cov khoom siv thiab kev tua hluav taws. Labs uas siv cov khoom sib xws, ntawv pov thawj feldspathic hmoov thiab calibrated ncu xa tuaj yeem ua kom lub ntsws thiab haum.
• Hloov pauv thiab txhawb nqa. Cov chaw kuaj mob txawv teb chaws zoo li peb muab cov nqi sib tw thiab cov ntaub ntawv hloov pauv digital, tab sis paub meej tias lawv tswj kev kho kom zoo.
• Hybrid muaj peev xwm. Lub chaw kuaj mob zoo tuaj yeem hloov mus rau e.max lossis txheej txheej txheej yog tias qhov kev npaj hloov pauv.

Peb tsim ADS nyob ib puag ncig ntev - kev koom tes nrog cov kws kho mob txawv teb chaws. Peb tswj hwm tag nrho cov digital-rau- tes ua haujlwm kom koj tau txais kev zoo nkauj zoo ib yam yam tsis muaj nyiaj siv ua haujlwm hauv - tsev ceramist.
