Kev coj zoo nyob rau hauv lub neej niaj hnub yog muab ntau xim. Tsis yog lub ntsiab lus kawg yog muab rau luag nyav. Nws tsim thawj lub tswv yim ntawm ib tug neeg thiab muab nws lub siab ntawm kev ntseeg siab. Txawm li cas los, tsis yog txhua leej txhua tus yuav khav txog Hollywood luag nyav. Txhawm rau kho qhov teeb meem qub tib si yuav pab tau cov khoom ua si. Cov tshuaj niaj hnub no muaj peev xwm tsim tau tiag tiag txuj ci tseem ceeb.
Dab tsi yog qhov veneer nyob rau hauv kev kho hniav?
Cov no yog microprostheses uas zoo li nyias daim hlau. Lawv raug siv los muab cov hniav ib hom thiab xim. Vim yog qhov tseeb tias cov cuab yeej siv yees siv hauv kev ua cov tshuab ua lag luam, cov ntawv no yuav pom qhov ntuj. Cov kws kho mob nrog cov kab xaum qhuav - qhov no yog qhov txawv txav rau cov khoom siv nrog cov tshuaj tua hluav taws xob.
Lub tswv yim zoo li no raug samfwm kom ua rau cov hauv qab no:
- Qhov xim ntawm tus hniav txha hniav tau pauv lawm. Vim yog siv tej yam tshuaj, lub incisors tuaj yeem pleev xim rau hauv cov xim liab los yog liab hawj. Ntxiv rau, cov xim ntawm cov hniav pauv nrog cov ntsiab lus ntawm cov tshuaj fluoride hauv dej.
- Ntau dhau ntawm lub incisors. Tib lub microprosthesis pab rau theem qhov siab ntawm cov hniav.
Lawv muaj cov khoom siv zas thiab cov khoom siv ua kom siv. Cov no suav nrog cov hauv qab no:
- kev puas tsuaj ntau;
- tsis raug tom ;
- tus hniav fluoridation;
- qhov muaj cov cwj pwm phem (gnaw tes, khoom txom ncauj thiab lwm yam);
- inflammatory txheej txheem nyob rau hauv lub qhov ncauj kab noj hniav;
- muaj zog ua kom hniav tsis tau "cov ntaub so ntswg".
Qhov sib txawv ntawm cov khoom sib xyaw thiab cov pam cav sib txawv yog dab tsi?
Cov microprosthetics txawv ntawm ib leeg. Cov ntsiab lus yog "ncaj". Lawv raug ntsia hauv ib qho mus ntsib kws kho mob. Cov txheej txheem ntawm restoration ntawm cov hniav muaj nyob rau hauv txheej txheej-los-txheej daim ntawv thov ntawm ib tug composite on ib tug saum npoo. Vim li ntawd, qhov microprosthesis tau muab sib txuas nrog rau "cov ntaub so ntswg" thiab cov khoom ntiag tug tsis ua. Cov ntaub ntawv admirably emits enamel, yog li cov veneers yog kiag li sib txawv los ntawm lwm cov hniav.
Ceramic micro-prostheses (lawv kuj hu ua porcelain) yog tsim nyob hauv cov chaw kuaj ntshav tshwj xeeb, kev xav txog kev ntsuas ua ntej tus neeg mob. Cov ntawv cog hniav tiav tas yog cov nplaum ntawm cov hniav rov qab los nrog kev pab ntawm ib qho "nplaum" tshwj xeeb. Thaum xaiv cov kabmob sib xyaw los yog ceramic vuas, tus neeg mob yuav tsum nug tus kws kho mob kom paub meej txog qhov zoo thiab qhov tsis zoo ntawm cov microproseses. Tom qab ntsuam xyuas cov ntaub ntawv tau txais thiab mloog cov lus pom zoo ntawm tus kws kho hniav, nws yuav yooj yim rau nws kom txiav txim siab tshaj.
Cov khoom sib txuam thiab qhov txua ntoo - nws zoo dua?
Lub hom phiaj kev soj ntsuam ntawm cov kev sib piv ntawm cov microprocthes yuav pab txhawm rau txheeb xyuas lo lus nug no. Txij li thaum lub advent ntawm composite veneers lawv tau raug siv raws li ib qho lwm txoj rau ceramic daim hlau. Txawm li cas los xij, xws li microprosthes tau visually nkaum tsuas yog me ntsis teeb meem. Lawv tuaj yeem raug siv raws li hauv qab no:
- hloov nyob rau hauv tus qauv ntawm cov hniav pem hauv ntej vim nws cov raug lossis raug mob me;
- tsis sib haum xeeb ntawm lub caj dab ntawm lub cuab tam;
- pigmentation ntawm enamel, uas tsis txais nws tus kheej mus rau bleaching;
- darkening dhau lub sij hawm sau cov khoom.
Txawm li cas los xij, tsuas yog kho dua tshiab nrog cov khoom siv ua xua (ceramic veneers) thiaj li yuav pab tau zais cov nram no:
- thinning lossis hypoplasia ntawm tus txiv roj ;
- kev puas tsuaj ntxiv ntawm incisors los ntawm kev mob bruxism lossis lwm yam kev mob;
- pathological tom.
Veneers - tus tshaj lij thiab cov av
"Ncaj nraim" microprosthetics muaj xws li cov yam ntxwv zoo:
- txuag cov neeg mob lub sij hawm (kev txhim kho ntawm cov ntawv teeb duab uas tau ua rau nws tsuas yog 1 mus ntsib tus kws kho hniav);
- cov nqi ntawm kev kho kom rov zoo dua yog pheej yig dua nrog cov kab xaum qhwv;
- Cutters undergo tsawg noj ua ntej decorating.
Hom microprosthesis no nws cov teeb meem. Qhov tseem ceeb tshaj plaws yog cov nram qab no:
- Ntev mus, lawv tuaj yeem hloov xim;
- lawv muaj zog nyob rau hauv kev sib piv nrog cov kab xev;
- kev pab cuam luv luv (ntawm 3 txog 7 xyoo);
- hnov mob cawv (lawv raug rhuav tshem hauv dej cawv thiab rinsers, uas muaj ethanol).
Cov phom kub muaj qhov zoo nram no:
- lub zog thiab kev ua haujlwm;
- resistant rau ntau cov khoom noj xim, thiaj li tsis muaj deg stains thiab cov quav hniav tshwm sim;
- pab kom rov tsim kho tus qauv ntawm tus hniav, uas yog rov qab los.
Qhov tsis zoo ntawm cov phom txiv hmab txiv ntoo yog cov tsawg dua cov lus tshaj tawm hauv qhov "ncaj" microprostheses. Qhov tseem ceeb tshaj ntawm cov no yog cov nqi ntawm kev kho kom zoo siab. Nyob rau hauv tas li ntawd, qhov tsis zoo yog qhov tseeb tias lub installation ntawm cov yas daim hlau tsis tuaj yeem ua rau ib lub sij hawm. Thaum mus ntsib thawj zaug, tus kws kho hniav npaj tau cov hniav thiab ua rau lub tswv yim, thiab ib qho veneer ib ntus txuas nrog rau ntawm lub pob txha. Thaum tus kws kho mob mus ntsib tus kws kho mob dua, qhov muab lub microprosthesis tshem tawm, thiab qhov ruaj khov kho ruaj khov kho hauv nws qhov chaw.
Kev nruab ntawm cov khoom siv ua xaum
Tag nrho cov txheej txheem ntawm microprosthesis yuav tsum conditionally muab faib ua ntau theem:
- Soj ntsuam. Tus kws kho hniav ua tus txheej txheem kuaj xyuas pom (kuaj cov kab noj hniav hauv qhov ncauj) thiab xaiv lub suab ntawm microprostheses. Hniav nws tus kheej muaj 3 qhov sib txawv me ntsis: basal, yooj yim thiab txiav cheeb tsam. Txhua tus ntawm lawv muaj nws tus kheej ntxoov ntxoo, yog li ntawm txoj hauj lwm ntawm tus kws kho hniav yog xav nrhiav kev xaiv dav dav.
- Kuaj. Raws li cov khoom ua tau luam tawm cov ntawv tais diav. Qhov no ua rau cov cuab yeej siv ntawm cov tais diav (ceramic veneers) ua ze rau cov hniav thiab cov khoom zoo.
- Soj ntsuam. Nyob rau qib no, lub microprosthesis yog thawj zaug sim thiab tom qab ntawd.
Taws ntawm cov hniav nyob rau hauv qhov ceramic veneer
Cov txheej txheem no yog ua tiav nrog rau kev txhim kho ntawm cov nyiaj tso ncaj thiab tsis ncaj nraim. Npaj cov khoom ua noj ua ke, uas yog sawv cev los ntawm cov theem nram qab no:
- Thov mus rau saum npoo ntawm transverse furrows.
- Xaws approximally sab.
- Kev tsim ib ntug kev. Nyob rau theem no, qhov kev sib tsuam yog nqa tawm ntawm ib qhov tob ntawm 1-2 hli.
- Kev kho mob ntawm thaj chaw khiav nkaum.
- Kev rhuav tshem, uas tshem tag nrho cov npoo ntse.
Kho cov khoom siv ua xua
Tom qab tig cov hniav, tus kws kho mob pib txhim kho qhov microprostheses. Fixation ntawm veneers ib txhij cuam tshuam 3 qhov chaw:
- tawv cutter ntaub;
- ceramic phaj;
- "Lub nplhaib".
Cov chaw no sib txawv ntawm ib leeg hauv cov tshuaj lom neeg muaj pes tsawg leeg, yog li ntawd, rau qhov kev kho kom muaj zog, kev kho tshwj xeeb ntawm lawv txhua tus yuav tsum tau ua. Lub veneer yog fastened raws li nram no:
- Lub phaj paj yog them nrog hydrofluoric acid. Raws li ib qho ntawm cov haujlwm no, cov pores tshwm nyob rau ntawm qhov microprosthesis, uas yav tom ntej yuav muab ib qho kev sib koom tes zoo.
- Cov hniav qub txeeg qub tes yog kho nrog ib qho khoom plig.
- Ib cov kua qaub av tshwj xeeb yog siv rau cov nplais ntawm lub hau kom txog 15 feeb.
- Tus hniav yog them nrog ib tug primer thiab qhuav. Tom qab ntawd nws yog siv "kua nplaum".
- Sab nraub qaum ntawm cov ntawv phaj yog them nrog tus kho lub hau, thiab cov veneer txuas nrog cov hniav rov qab. Tus neeg hais lus "kua nplaum" muab tshem tawm.
- Kev sib tsoo deg thiab polymerization yog nqa tawm.
Cov Peeb Zaum Plaub Hlis - kev pab cuam lub neej
Kev khiav hauj lwm lub sij hawm ntawm cov ntaub ntawv zoo li no ntev tshaj li ntawm cov kua microprostheses . Qhov kev pab cuam lub neej ntawm ceramic veneers yog ntau tshaj 20 xyoo. Txawm li cas los, tsuas yog cov neeg mob uas ua raws li cov tswv yim nram no tuaj yeem suav tau rau ntawm qhov no:
- ob zaug ib xyoos ntsib tus kws kho hniav;
- soj ntsuam tus kheej kev tu cev;
- tiv thaiv cov hniav ntawm kev quab yuam (tsis txhob gnaw ceev, tsis txhob qhib lub raj mis).
Puas yog nws ua tau txhim kho tau qhov teeb meem ntawm ceramic?
Tus kws kho mob tuaj yeem ua tau ib feem ntawm txoj kab ntawv cov hniav, tab sis peb tham txog kev kho me me. Tag nrho cov kev kho yuav tsum tau ua ua ntej kev teeb tsa (nyob rau ntawm cov theem tsim nyog). Muab hais tias tus kws kho hniav yog ib lub koob yees duab tiag tiag, nws tsis muaj kev kho ntxiv tom qab kev txhim kho. Qhov no yog vividly los ntawm ceramic veneers - cov duab ua ntej thiab tom qab.
