Tsis ntev tas los no, ib qho tshiab tshwm sim hauv kev kho hniav - kev ua txhaum. Kab lus no yuav pab koj paub tias nws yog dab tsi.
Ib tug abutment yog ib qho txuas uas txuas rau kev cog hniav thiab hniav hniav.
Ob peb lub hlis thiab rau lub hlis tom qab kev ua haujlwm no, raws li, ntawm lub puab tsaig sab sauv thiab sab sauv, siv kev sojntsuam, qhov chaw ntawm qhov chaw intraosseous ntawm cov implants nyob rau hauv lub mucous membrane yog txiav txim siab. Cov kws tshaj lij saum lawv excise lub mucous daim nyias nyias, unscrewing lub plug thiab screwing nyob rau hauv cov pos hniav shaper. Tom qab ob peb lub lis piam, qhov tsim no yog hloov los ntawm kev txhawb nqa abutment (titanium taub hau), uas protrudes rau hauv qhov ncauj kab noj hniav. Lub abutment yog ntsia tsuas yog tom qab txhim khu kev qha thiab zaum kawg engraftment ntawm qhov cog.
Txoj Cai Ua Haujlwm
Lub implant abutment yog screwed rau hauv, tab sis cov txheej txheem no tsis yog sai thiab tsis mob li nws zoo nkaus li. Qhov no yog vim tias tom qab cov txheej txheem kev cog qoob loo, nws yuav siv sij hawm tsawg kawg 3 lub hlis los kho.
Tseem muaj lub hauv paus abutment. Nws yog dab tsi, lawv tuaj yeem piav qhia ntawm kev sab laj nrog kws kho mob. Qhov no yog ib qho cog uas muaj peev xwm ua tau zoo ib yam li cov hauv paus hniav, thiab rau qhov no nws yuav tsum yognws qhov chaw zoo sib xws: cov hauv paus hniav cog yuav tsum nyob ib puag ncig ntawm cov pob txha, thiab tib lub sijhawm nws yuav tsum tsis txhob tawm ntawm cov pos hniav. Lub crown ntawm cov hniav nyob rau tib lub sij hawm yuav tsum yog saum cov pos hniav. Tsuas yog rau nws qhov kev teeb tsa, muaj qhov "txuas hloov pauv", uas yog qhov kev tshem tawm, yuav xav tau.
Ntse & Cov txiaj ntsig
- Tus tsa abutment yog 2.5mm siab.
- Tus tsim yog tus kheej-localizing.
- Nws muaj peev xwm los them rau cov hniav misalignment mus txog 40 °.
- Abutment placement yog txais tau rau cov neeg mob uas tshem tau cov hniav cuav.
- Kev yooj yim nkag ntawm cov pob qij txha, uas txo cov kev sib tham thiab kev phais.
- Tseem tuaj yeem siv rau hauv qhov chaw kho mob uas muaj teeb meem nrog kev cog angulations (qhov kev ncua deb tsis raug).
Paj theem
Thaum mus ntsib kws kho hniav, feem ntau muaj kev xav tsis tau rov qab los tsev sai li sai tau. Kev ntxhov siab tuaj yeem tshwm sim tom qab ntsuas cov kev hloov pauv tom ntej. Txhawm rau tiv thaiv koj tus kheej, koj yuav tsum tau npaj ua ntej, tshwj xeeb tshaj yog, nyeem txog qhov abutment, nws yog dab tsi, nrhiav kom paub, vim tias cov txheej txheem no ntev heev thiab hnyav, txhua yam ntawm qhov txawv txav ntawm tus neeg mob yog qhov tsis xav tau thaum lub sijhawm nws.
Kev Kho Hniav tau muab rau txhua qhov no, nrog rau qhov tseem ceeb tshaj plaws - kev txom nyem ntawm tus neeg mob. Txhawm rau tiv thaiv lawv, muaj tshuaj loog, uas tso cai rau koj los ua kom tus kws kho mob tshwj xeeb ua rau mob heev. Kuj muaj mob tom qabinstallation, tab sis qhov no yog ib tug kiag li phenomenon. Tom qab tag nrho, kev ncaj ncees ntawm lub cev tau ua tiav kev phais mob, thiab yog li ntawd, cov txheej txheem ntawm kev kho thiab kho yuav tsum muaj qhov chaw. Ua tib zoo saib xyuas qhov mob thiab tsis xis nyob tsuas yog tom qab ib lub lim tiam ntawm kev kho mob.
Nyob ntawm abutments
Muaj ntau hom kev abutments, tab sis feem ntau yog Kho Abutment, Uni-abutment, Pob Abutment thiab Angled Abutment.
Kev kho mob abutments yog siv thaum kho cov nqaij mos kom ntseeg tau tias qhov ntev ntawm cov pa abutment yog qhov tseeb.
Standard (zoo ib yam) abutment muaj rau qhov ntev kev xaiv, uas yog ntsuas los ntawm qhov loj ntawm lub cylindrical ntsug ib feem ntawm cog, thiab ob txoj kev xaiv rau lub kaum sab xis ntawm lub khob hliav qab (45 thiab 20 °).
Angled abutments muab lub kaum sab xis ntawm inclination los ntawm longitudinal axes ntawm kev txuas. Nws yog sib npaug rau 30 °. Tsuas muaj ob txoj kev xaiv ntev. Upper cone - nrog lub kaum sab xis ntawm 20 °, raws li nrog rau tus qauv abutment. Lub abutment yog ib qho kev tivthaiv uas tsis muaj qhov sib cais hauv nruab nrab. Kev teeb tsa tau yooj yim heev kom ntseeg tau tias cov khoom nyob hauv txoj haujlwm raug, nrog rau kev tiv thaiv micro-tawg ntawm cov cement slurry los ntawm qhov ncauj mus rau thaj tsam subgingival.
Kev cai abutment lossis standard?
Los ntawm lub npe nws tus kheej, koj tuaj yeem nkag siab tias thawj hom abutment yog tsim los ntawm tus kheej thiab tsuas yog hauv ib daim qauv xwb. Nws yog tus cwj pwm los ntawm daim ntawv nruj, tsim nyog rau ib rooj plaub tshwj xeeb. Ib tus neeg siv zirconium yog ua nruj me ntsis raws li cov duab, uas feem ntau lub hauv paus incisor yuav tsum muaj. Yog li ntawd, cov pos hniav zoo dua kev txhawb nqa. Tsis muaj qhov chaw tob hauv qab cov pos hniav rau "streaks" ntawm cement.
Feem ntau, cov qauv abutments yog titanium, lawv tau nruab rau hauv qhov ncauj kab noj hniav. Lub titanium abutment muaj cov duab ntawm "lub tog raj kheej", thaum lub ntsej muag ntawm cov hniav tiag tiag tsis rov ua dua, thiab tsis yog qhov tseeb ntawm cov pos hniav khaws cia. Tsis tas li ntawd, thaum lub sij hawm txhim kho lub crown rau xws li abutment, hais txog ntawm cov cement tuaj yeem nkag mus rau hauv qhov sib txawv ntawm cov pos hniav thiab nws.
Abutments raug txuas rau hauv txoj kev no:
- Screw method: lub crown yog screwed rau ntawm abutment. Txoj kev txuas no yooj yim heev uas nws muaj peev xwm tshem tawm cov qauv rau kev kho dua tshiab.
- Cementing: cov pob qij txha yog tsau rau ntawm abutment siv cov cementing tshwj xeeb. Qhov yooj yim ntawm hom kev kho no yog qhov zoo nkauj zoo nkauj thiab kev nplij siab thaum lub sijhawm ua haujlwm ntawm cov qauv tau nce.
Nyob zoo ntawm kev cai abutment
Nws qhov txiaj ntsig tseem ceeb tshaj plaws yog ua tiav tus kheej thiab lub cev. Qhov no tsis yog tsuas yog ib qho tseem ceeb ntawm kev zoo nkauj, nws tseem pab tiv thaiv cov cement los ntawm cov pos hniav thaum lub sij hawm fixation rau lub crown abutment. Qhov no yog ib qho tseem ceeb heev, txij li thaum lub tsim ntawm txawm ib tug imperceptible zaj duab xis ntawm cov pos hniav thiab tus txheej txheem abutment tom qab ib pliag tuaj yeem ua rau peri-implantitis (pob txha poob ib ncig ntawm cov implants).
Nws tshwm simvim lub fact tias xws li ib tug dog dig abutment yog nqaim tshaj lub crown nws tus kheej, yog li ntawd lub fixation ntawm lub tom kawg nrog xis mas tshwm sim nyob rau hauv xws li ib txoj kev uas nws yog cia pressed ntawm lub abutment thiab cov pos hniav. Qhov teeb meem no yog aggravated los ntawm qhov tseeb hais tias nyob rau hauv tus txheej txheem ntawm masking lub abutment, tus kws kho mob muab ib tug ledge hauv qab no cov pos hniav theem nyob rau hauv thiaj li yuav nkag mus rau hauv lub ntug ntawm lub crown thiab tag nrho cov hlau txhawb nqa. Qhov no tuaj yeem ua rau qhov kev nkag tsis tau ntawm cov cement rau hauv thaj chaw uas nws yuav tsis tuaj yeem tau txais nws. Kev mob tshwm sim tsis tshwm sim tam sim ntawd.
Kev saib xyuas tom qab ua haujlwm thiab teeb meem
Kev saib xyuas tshwj xeeb tom qab yuav tsum tau ua tiav tom qab qhov kev tso kawm tiav. Kev saib xyuas tshwj xeeb yog dab tsi?
Lub sijhawm no yog lub hauv paus tseem ceeb ntawm kev kho kom rov zoo. Feem ntau nws mob me ntsis, tab sis tsuas yog thaum xub thawj. Kev tu tag nrho nrog tus txhuam hniav mos yuav ua tau ob peb hnub tom qab ua haujlwm. Tus kws kho hniav tus kheej tuaj yeem piav qhia txog txoj hauv kev saib xyuas, hais txog kev kho mob, nws yog dab tsi, pom zoo ntxiv cov khoom siv tu cev ntawm qhov ncauj.
Koj yuav tsum mus ntsib kws kho mob yog:
- Cov pos hniav uas nyob ib puag ncig tus qauv tseem o thiab mob tom qab ib lub lim tiam.
- Cov kua dej tawm ntawm cov pos hniav nyob ib ncig ntawm lub abutments.
- Mob persists los yog rhiab nyob ib ncig ntawm ib qho ntawm cov implants.
Qhia tus nqi
Nyob rau hauv kev lag luam ntawm kev kho hniav prosthetics, txoj cai nqi yog ntau haiv neeg. Tus nqi nruab nrababutment yog los ntawm 30 euros thiab siab dua. Xws li tus nqi nyob ntawm cov ntaub ntawv ntawm kev ua tiav thiab qib ntawm lawv qhov zoo, txij li cov cuab yeej tau nyob hauv ib puag ncig hnyav rau ntau lub hlis. Lub abutment yuav tsum tsis txhob ua phem rau tus neeg hnav hauv txhua txoj kev. Yog li ntawd, tus nqi tsim nyog. Kev kho hniav niaj hnub no ua tib zoo xav txog kev tsim cov qauv no, yog li tsis muaj laj thawj txhawj xeeb.
