Microprosthetics ntawm cov hniav yog ib qho kev kho hniav tshiab, lub hom phiaj yog los khaws cov hniav puas, rov ua haujlwm thiab txhim kho lawv cov tsos.
Nov yog ib txoj hauv kev niaj hnub los kho cov hniav thiab cov hniav, uas siv cov fiberglass thiab ceramics tshiab.
Txoj kev ncaj thiab ncaj qha ntawm kev kho hniav
Nyob rau hauv kev kho hniav zoo nkauj, txoj kev tsis ncaj thiab ncaj qha ntawm kev kho hniav yog siv los kho cov neeg mob. Txoj kev ncaj nraim yog to taub raws li kev ua haujlwm kho dua tshiab hauv tib neeg lub qhov ncauj. Txoj kev tsis ncaj qha cuam tshuam nrog kev tsim cov kev kho kom rov zoo los ntawm kev xav hauv chav kuaj hniav. Microprosthetics yog ib txoj kev kho tsis ncaj.
Nws txawv ntawm lwm txoj hauv kev. Cov txheej txheem ntawm kev kho cov hniav siv hauv microprosthetics yog maj mam thiab ua kom tsis txhob cuam tshuamfeem ntau, cov hniav uas nyob ib sab.
Onlays thiab inlays (siv rau kev kho hniav kho hniav) yog kev cai tsim nyob rau hauv lub chaw kuaj thiab yog tshwj xeeb ruaj ruaj piv rau cov yas thiab cov duab ntim siv hauv kev kho hniav.
Kev nce qib, kev kho hniav kom hniav zoo nkauj yog siv cov tswv yim siv hauv micro-prosthetics kom cov hniav tsis zoo, uas yog, tsim kom muaj "Hollywood luag nyav".
Hauv qab no, xav txog cov hom ntawm cov txheej txheem no ntawm prosthetics.
Hom ntawm cov txheej txheem no prosthetic
Muaj ntau hom microprosthetics hauv qab no:
Adhesive prosthetics. Cov txheej txheem no ua rau nws tuaj yeem hloov tau ib lossis ob tus hniav uas ploj lawm nrog prostheses. Rau prosthetics, fiberglass feem ntau yog siv, uas muaj lub zog tshwj xeeb. Cov cuab yeej no ua rau nws tuaj yeem ua cov txuas hniav nrog lub neej ua haujlwm ntev. Ntawm lwm yam, microprosthetics ntawm cov hniav nrog fiberglass ua rau nws ua tau rau nruab ib tug choj prosthesis nyob rau hauv ib tug mus ntsib kws kho mob. Lub fiberglass beam yog txuas rau cov hniav uas nyob ib sab nrog cov nplaum tshwj xeeb, thiab cov hniav yog tsim los ntawm cov kab hluav taws xob los ntawm cov khoom siv kho kom zoo nkauj. Cov hniav uas nyob ib sab tsis depulped. Microprosthetics ntawm cov hniav uas ploj lawm siv fiberglass tshwj xeeb yog qhia rau cov neeg uas tsis haum rau cov hlau ntawm cov hniav hniav. Tus nqi ntawm tus choj ua nrog fiberglass yog tsawg dua piv rau lwm tustxoj kev ntawm prosthetics
- Microprosthetics nrog overlays (veneers). Veneers yog nyias daim hlau uas txuas rau sab nrauv ntawm cov hniav thiab txhim kho cov hniav zoo nkauj. Siv hom no, koj tuaj yeem txhim kho cov xim thiab cov duab ntawm koj cov hniav, nrog rau zais cov chips, thaj chaw ntawm qhov tsaus ntuj thiab puas ntawm cov enamel. Cov ntaub qhwv no tseem ua haujlwm tiv thaiv, tiv thaiv cov hniav enamel los ntawm kev quab yuam ntawm tshuaj yej, kas fes, haus luam yeeb thiab lub cev muaj zog. Thaum prosthetics ntawm cov hniav pem hauv ntej los ntawm kev overlays, qhov tsis zoo ntawm cov hniav tuaj yeem muab zais.
- Siv tabs. Micro-prosthetics ntawm cov hniav nrog inlays hais txog kev siv cov khoom tshwj xeeb ua hauv chav kuaj. Lawv ua kom zoo nkauj thiab muaj zog ntau dua thiab muaj zog dua li cov teeb pom kev yooj yim.
Pins. Nyob rau hauv cov kev tshwm sim hais tias tus hniav crown raug rhuav tshem, tab sis lub hauv paus noj qab haus huv, micro-prosthetics ntawm cov hniav yog siv los ntawm cov pins. Ib tus pin yog muab tso rau hauv lub hauv paus ntawm cov hniav thiab ces ib tug crown yog tsim los ntawm nws lub hauv paus. Cov txheej txheem ntawm cov khoom siv no ua rau nws tuaj yeem txhim kho cov hniav ntawm cov hniav uas puas lawm yam tsis tig cov hniav uas yog los ntawm cov ntsia hlau ntsia ntawm ob sab
theem tsim thiab txhim kho microprostheses
Muaj ntau theem ntawm kev tsim thiab txhim kho micro-prosthesis. Feem ntau ib tug neeg yuav tsum tau mus ntsib kws kho hniav ob zaug.
Thaum mus ntsib thawj zaug, cov hniav raug kho: cov ntaub so ntswg tuag raug tshem tawm ntawm qhov pom ntawm caries, kab noj hniav raug tsim, uas tom qab kaw.tab.
Yog hais tias muaj kab noj hniav tsim nyob rau hauv cov hniav, ib tug hardening muab tshuaj txhuam yog siv rau cov hniav ntawm txhua lub puab tsaig ntawm ib tug tshwj xeeb diav ntawm ib sab kom impressions. Ib qho kev xav ntawm cov hniav uas cuam tshuam yog siv los ua micro-prosthesis, thiab los ntawm lwm lub puab tsaig - kom haum rau cov micro-prosthesis, tshwj xeeb tshaj yog nws zom zaws, mus rau cov hniav zoo li cov kab lus ntawm cov hniav.
Cov xim ntawm tib neeg cov enamel thiab cov cam khwb cia ntawm cov hniav raug xa mus rau chav kuaj, qhov chaw microprosthesis yuav ua los ntawm cov kws kho hniav.
Thaum lub sijhawm ua microprosthesis mus tas li (ib mus rau ob lub lis piam), cov kab noj hniav raug kaw nrog ib ntus txhaws.
Thaum mus ntsib zaum ob, tus kws kho mob yuav tshuaj xyuas seb qhov ua tiav micro-prosthesis yuav zoo li cas hauv cov xim thiab cov duab, thiab nruab rau hauv cov kab noj hniav uas tau npaj ua ntej.
Raws li tib lub algorithm, cov hniav cuav yog tsim rau kev teeb tsa ntawm veneers, pins thiab ib ntus "npauj npaim" hom.
microprosthetics ntawm cov hniav yog dab tsi, daim duab hauv qab no qhia.
Kev pab cuam lub neej ntawm onlays, txhaws, hniav hniav thiab crowns
Qhov tseem ceeb ntxiv yog tias txhua yam khoom uas hloov kho hniav tsis xws luag thaum lub sijhawm txheej txheem yog ua nyob rau hauv xws li kuaj mob uas tsim tsis tau nyob rau hauv tus neeg mob lub qhov ncauj.
Cov xwm txheej tshwj xeeb ntawm kev ua thiab kev tsim cov veneers thiab inlays muab lub zog ntau dua, ib puas feem pua polymerization, yooj yim ntawm kev tsim kho (thaum nws los txog rau kev tsim cov choj-hom prostheses). Tag nrho cov no yog qhov lojdegree nce kev pab cuam lub neej ntawm microprostheses.
Fiberglass txuas hniav muaj qhov nruab nrab lifespan ntawm tsib xyoos, inlays 10-12 xyoo thiab veneers ntev tshaj 20 xyoo.
Cov ntsiab lus no tuaj yeem sib txawv ntawm qhov nce thiab nqis, nyob ntawm tus kheej tus yam ntxwv ntawm lub cev.
Indications rau microprosthetics
Microprosthetics tau qhia nyob rau hauv cov xwm txheej hauv qab no:
- yog tias muaj qhov tsis xws luag ntawm cov hniav uas tsis yog-carious thiab carious keeb kwm (ntawm 30 txog 50% ntawm cov ntaub so ntswg saum cov pos hniav);
- txhawm rau txo cov hniav thiab xoob thaum muaj cov kab mob hauv lub cev;
- kom tiv thaiv cov hniav ntau dhau;
- yog tus neeg mob xav txhim kho cov xim thiab cov hniav kom zoo nkauj.
Qhia qhov no, ua ntej thiab tom qab duab, thaum tib neeg tau txais lub ntsej muag luag ntxhi zoo li cov hnub qub nrov.
Contraindications rau cov txheej txheem prosthetic
Txoj kev no muaj qee yam contraindications. Cov no suav nrog:
- txheej txheem ntau thiab nquag carious;
- tsis zoo qhov ncauj;
- tsis tuaj yeem ua kom tiav qhov ziab ntawm qhov chaw kho hniav;
- kab tob tob.
Qhov no yuav tsum tau coj mus rau hauv tus account.
Tus nqi ntawm microprosthetics hauv St. Petersburg
Tus nqi ntawm ntau hom micro-prosthetics yuav txawv tsis yog nyob ntawmcuam tshuam cov hniav zoo li cas, tab sis kuj nyob ntawm qhov tsim nyog ntawm tus kws kho hniav, cov khoom zoo.
Tus nqi sib txawv ntawm kev ua haujlwm ntawm qhov xwm txheej no hauv St. Petersburg yog li ntawm plaub mus rau nees nkaum tsib txhiab rubles. Txawm li cas los xij, qhov zoo ntawm microprostheses, cov khoom zoo nkauj zoo nkauj, kev saib xyuas yooj yim thiab kav ntev ua rau tag nrho cov nqi ntawm fabrication thiab installation.
Kev tshuaj xyuas ntawm micro prosthetics
Microprostheses txawv los ntawm kev txhaws hauv qhov uas lawv tau tsim hauv chav kuaj, thiab yog li lawv yuav luag zoo tag nrho cov duab thiab xim ntawm tib neeg cov ntaub so ntswg. Cov ntaub ntawv, ntxiv rau qhov ua kom zoo nkauj tseem ceeb, zoo nkauj heev, yooj yim thiab siv tau yooj yim.
Microprosthetics ntawm cov hniav yog sau rau kev puas tsuaj loj ntawm cov hniav enamel, ua tsaug uas koj tuaj yeem rov ua kom zoo nkauj ntawm koj luag ntxhi thiab zom cov haujlwm.
Qhov laj thawj rau kev txhim kho micro-prostheses txawv. Yog li, piv txwv li, hauv qee tus neeg mob, tsuas yog "rau" raug rhuav tshem, thaum lub zom zom tau puas lawm. Cov hniav uas nyob ib sab tau noj qab nyob zoo, yog li tsis tas yuav tsum muaj tus choj. Tus kws kho hniav nyob rau hauv rooj plaub no qhia tab. Nws yog ib qho kev xaiv zoo uas tso cai rau kuv tsis txhob nruab ib qho yooj yim sau. Lub inlay tau tsim nyob rau hauv lub chaw soj nstuam raws li cov cam khwb cia, nws merged nrog enamel nyob rau hauv kev ntxhib los mos thiab xim, thiab yog li ntawd yog tsis pom nyob rau hauv lub qhov muag prying.
Dab tsi yog qhov tsis zoo ntawm txoj kev no?
Ntawm qhov tsis zoo ntawm microprosthetics, cov neeg mob paub qhov txawv hauv qab no:
- siab duatus nqi piv rau cov pa filling;
- mus ntsib kws kho hniav ob lossis peb zaug.
Qhov tseem ceeb tshaj plaws yog ua cov txheej txheem hauv tsev kho mob uas ntseeg siab, feem ntau vim yog kev tsis saib xyuas ntawm cov kws kho mob, cov neeg mob tau ntsib qhov tsis zoo ntawm microprosthetics: mob ib ce, kev puas tsuaj ntawm cov pob txha thiab cov pos hniav.
