Vim li cas koj lub zirconia tawg?

Milling tseem yog qhov tsim nyog tshaj plaws thiab siv dav siv hauv kev kho hniav niaj hnub no. Muaj ob lub laj thawj tseem ceeb uas nws tseem yog lub hauv paus ntawm kev lag luam. Ua ntej, milling tshuab thiab software tau txhim kho loj heev hauv 10 xyoo dhau los; thiab qhov thib ob, kev loj hlob ntawm ntau yam ntawm cov ntaub ntawv millable muaj yog staggering,zirconia pmma ua, lithium disilicate... koj tab tom ntsib ntau dua 10 hom khoom txhua hnub. Cov tshuab milling tam sim no txawm tias muaj ntau yam kev siv tshuab, xws li hloov cov cuab yeej tsis siv neeg, raws li lub tshuab xam zauv lub neej. Raws li nyob rau hauv ib qho kev lag luam, txawm tias cov kev nce qib hauv kev siv tshuab, yuav muaj teeb meem los daws teeb meem. Nws yog ib qho tseem ceeb rau lub chaw soj nstuam kom kawm paub yuav ua li cas txheeb xyuas cov teeb meem nrog lawv cov tshuab yam tsis muaj kev cia siab rau cov yam ntxwv tsis siv neeg.

Ib qho ntawm cov lus nug uas nquag nug txog milling yog, "Vim li cas kuv zirconia tawg?". Muaj, ntawm chav kawm, ib lub roob ntawm variables. Piv txwv li, leej twg lossis ib qho kev sib xyaw ua ke ntawm cov hauv qab no tuaj yeem raug liam tias: tsim tsis zoo; kev ua zes tsis raug; phem connectors los yog ncej tsim; zirconia tsis qhia rau lubKev kho hniav CADCAM milling tshuab/kev kho hniav milling bur/zirconia milling disc; tsis zoo milling tshuab txij nkawm; tsis zoo milling tswv yim; ntsuab xeev mishandling; tsis zoo infiltration kua; kev ua kom qhuav tsis zoo; sintering qhov cub cov kev pab cuam; tsis zoo pob zeb diamond thiab rotaries tom qab sintering; txheej txheem tiav; thiab qhov cub voj voog. Cov teeb meem tib yam no tuaj yeem tshwm sim txawm tias lub chaw kuaj mob siv zirconia thiab burs uas tau qhia los ntawm cov chaw tsim khoom siv lub tshuab milling.

Xav txog txhua yam uas tuaj yeem ua rau muaj kev tawg thaum lub sijhawm tsim khoom, qhov teeb meem yog qhov nyuaj heev los kuaj xyuas yam tsis pom zirconia thiab lub tshuab hauv nqe lus nug. Cov kws tshaj lij feem ntau tau ntsib thiab paub tias lawv ua dab tsi, yog li cov neeg siv yuam kev tsis tshua muaj qhov teeb meem. Txhawm rau pab txheeb xyuas qhov teeb meem, ua ntej xav txog seb qhov kev kho kom rov zoo li cas. Yuav luag txhua zaus nws yog tag nrho-on-X lossis qee yam kev cog lus-txhawb nqa. Qhov no ua rau muaj kev nkag siab zoo vim tias cov neeg tsim khoom tuaj yeem tawm mus nrog cov kev coj ua tsawg dua li qhov zoo tshaj plaws thaum ua ib chav, tab sis cov tib txoj kev no yuav ua rau muaj teeb meem loj dua. Qhov thib ob, kev tshuaj xyuas qhov kev tsim khoom zoo li cas yuav qhia tau tias nws tau raug tsim raug thiab tau txais kev txhawb nqa zoo. Feem ntau, cov no tsis yog lub hauv paus ntawm qhov teeb meem tawg, tab sis lawv yuav tsum tau hais ua ntej kom tshem tawm. Tom ntej no, nws yog ib qho tseem ceeb rau ib tus neeg tshiab los saib cov txheej txheem infiltration, txawm tias tus kws tshaj lij tau dhau los ntawm tag nrho cov khoom no ob peb zaug lawm.

Nrog rau qhov pom tseeb tshaj plaws ua rau tawm ntawm txoj kev, muaj ib qho kev ua txhaum loj. Qhov teeb meem tsis pom zoo tshaj plaws tuaj yeem pib txheeb xyuas los ntawm kev nug tus kws tshaj lij, "Puas yog koj lub zirconia ci iab?" Txawm hais tias muaj kev tsis ntseeg txog qhov siv tau ntawm cov lus nug ntawd, tus sau tau pom tias "shininess" yog ib qho tsos mob ntawm qhov teeb meem tshwm sim.

Piv txwv li, ob daim duab hauv qab no qhia ob daim duab ntxoov ntxoo los ntawm daim ntawv qhia ntxoov ntxoo.

Hauv txhua daim duab, lub tab ntawm sab laug yog smoother thiab shinier dua tab ntawm sab xis. Thaum xub thawj siab ib muag, tus kws tshaj lij yuav xav tias nws yog qhov zoo kom muaj qhov chaw zoo li ncaj tawm ntawm lub zeb, tab sis qhov tseeb, nws tsis yog. Qhov saum npoo yog du vim tias cov milling burs tau pib npub thiab poob lawv ntug. Yog tias tus kws tshaj lij tsis tu ncua mills singles, lawv tsuas pom tias cov yas yog ci iab thiab tej zaum muaj qee qhov chipped margins. Qhov tseeb, hauv thawj daim duab, lub crown yog qhov tseeb muaj qee qhov me me ntawm cov npoo.

Qhov teeb meem nrog kev khiav dull burs ntawm qhov cog cog loj-txhawb rooj plaub yog qhov kev cog lus cog lus thiab nkag mus rau qhov. Qhov kev ntxhov siab tshaj plaws ntawm cov txheej txheem yog qhov zoo li thaum lub cuab yeej npub pib tho lub qhov rau hauv zirconia. Thaum twg qhov pib qhov tob tiav lawm, cov kab noj hniav sab hauv tau yooj yim dua milled, tab sis qhov pib qhov tob yuav ua rau microfractures thiab kev ntxhov siab tawg. Ntawm tag nrho cov yas, xws li inconsistencies tau milled tam sim ntawd, tab sis nrog ib tug implant interface los yog nkag mus rau lub qhov, tsis muaj ntau npaum li cas tshaj cov khoom.

Cov ntaub ntawv pov thawj ntxiv ntawm qhov teeb meem no yog tias feem ntau cov xwm txheej zoo li no yuav tawg ntawm lossis dhau ntawm qhov abutments. Qhov no tsis yog vim zirconia yog nyias; Nws yog feem ntau vim yog microfracture. Lub zog ntawm cua sov thiab cua txias siv lub microfracture kom nws loj hlob mus rau ib yam dab tsi phem heev.

Raws li cov txheej txheem ua ntau dua automated thiab tswj tus kheej, nws yog ib qho yooj yim rau cov kws kho mob kom forego kawm yuav ua li cas los soj ntsuam zoo los yog tswj qhov zoo ntawm lawv cov cuab yeej. Feem ntau cov tshuab milling muaj cov cuab yeej lub neej txee lossis cov kwv yees, tab sis lawv yuav tsum tsis txhob suav hais tias yog lo lus kawg hauv lub neej cuab yeej. Qhov teeb meem tsis yog tias lawv yuam kev; es, nws yog yuav luag tsis yooj yim sua xav txog tag nrho cov variables. Piv txwv li, txawm tias ib lub chaw soj nstuam siv cov cuab yeej tsim nyog rau lub zeb, cov cuab yeej no yuav kav ntev npaum li cas nyob ntawm ntau yam ntawm zirconia siv, cov tswv yim milling ua haujlwm, bur manufacturers, thiab lwm yam. Qhov kev sib npaug no hloov tas li, yog li feem ntau qhov kev hloov pauv hloov pauv hloov pauv tuaj yeem ua tsis raug raws li qhov tshwm sim. Txij li qhov ci ntsa iab ntawm milled zirconia tuaj yeem qhia tau tias muaj qhov tsis zoo ua ntej lub tshuab lub cuab yeej saib xyuas lub neej, qhov "cov tsos mob" no yog qhov qhia tau zoo dua ntawm qhov xav tau hloov pauv. Cov chaw soj nstuam nrog cov kws tshaj lij uas paub saib xyuas lawv cov cuab yeej milling tuaj yeem ua haujlwm zoo dua cov ntaub ntawv tshiab thiab thev naus laus zis, tsis yog cia siab rau cov khoom lag luam thiab cov khoom lag luam.

Txhawm rau txiav txim siab qhov ua rau tawg zirconia, muaj tag nrho cov tswv cuab ntawm cov teeb meem thiab cov kev hloov pauv los xav thiab nkag siab; tab sis dull burs yog tus naj npawb ib. Raws li thev naus laus zis txhim kho, cov chaw kuaj mob yuav tsum tau tawm tsam qhov kev xav kom lees paub tias kev kuaj mob ntawm lub tshuab yog ib txwm muaj tseeb. Paub txog yuav ua li cas ntsuas cov cuab yeej siv hauv lawv lub chaw soj nstuam, cov kws tshaj lij yuav tswj hwm lawv cov txheej txheem thiab lawv cov khoom kawg.
