Yuav ua li cas xaiv cov neeg cog pom kev tshem tawm

Kev cog lus rov qab kho cov kev txom nyem (ntawm no xa mus rau "abutment")Feem ntau hais txog cov qauv nruab nrab uas txuas rau txoj kev cog hniav thiab cov ntawv thov. Cov kev ntxub ntxaug ua haujlwm zoo ib yam li cov qauv npaj kho hauv cov kev hloov kho cov pa. Nws muab kev txhawb nqa thiab khaws cia rau cov insthesis thaum tseem muab los tiv thaiv kev sib hloov thiab muab cov nta. Cov kev txom nyem tuaj yeem cuam tshuam rau cov yam ntxwv ntawm cov nqaij mos mos thiab cov ntaub so ntswg ntawm cov hniav cog qoob loo. Xaiv Kev Ua Kom Tsim Nyog Kev Txom Nyem ua lub luag haujlwm tseem ceeb tshaj plaws hauv kev txhim kho cov muaj sia nyob ua kom tsis muaj sia nyob.

Nrog kev nce qib sai ntawm moj tej hniav tsev kho hniav, cov tuam txhab txuas ntxiv rau kev ua haujlwm thiab kho lawv cov khoom. Txawm hais tias ntau yam ntawm abutments tuaj yeem ntsib cov kws kho mob muaj kev sib txawv thaum xaiv cov kev xaiv tsim nyog tshaj plaws. Txawm li cas los xij, muaj cov ntaub ntawv xov xwm tseem ceeb hais txog kev tsis pom zoo npaj abutments. Kab lus no ua kom paub cov qauv tsim, kev faib tawm, thiab xaiv cov qauv rau cov kws pov thaiv kom pab txiav txim siab.

 

1. Cov hom phiaj tsim ntawm cov abutment

Lub hom phiaj tsim nyog ntawm kev teeb meem xws li:

Kev sib txuas nruj nrog cov cog hniav kom txo cov microgaps ntawm kev cog qoob loo ntawm kev cog qoob loo thiab txo qis kev coj noj coj ua;

Tsis kam rau kev sib hloov rau ob qho tib si kev ntxub ntxaug thiab cov prosthesises;

Kev qhia txog qhov tseeb rau cov kev teeb meem thiab prosthesis;

Ib lub xub pwg tsim uas sib haum nrog kev sib deev contolity los tsim kev hloov pauv zoo tshaj plaws;

Kev Kho Mob ntawm kev ua kom zoo tshaj plaws occhlalal kev sib kis thiab faib;

Yooj yim ntawm kev tuav tshuaj kho thiab saib xyuas ntawm kev cog lus / prosthesis.

 

2. Hom ntawm kev cog lus abutments

Raws li kev tsim qauv, abursips tuaj yeem faib ua ntej ua ntej kev ua haujlwm thiab kev ua haujlwm raug cais.

 

2.1 preabricated abutments

Prefabricated abutments tau npaj-ua cov khoom lag luam tsim los ntawm cov tuam ntxhab rau cov ntawv thov kev kho mob yooj yim. Hom Hom muaj xws li cov kev ua kom pom tseeb, kho tau cov nyiaj txiag kub, pob txha me, Locator® abutments, thiab hybrid abutments.

 

2.1.1 Kev ua kom zoo nkauj

Cov no mimic lub ntuj bingively contour, nrog lub dab tshos siab dua piv rau lub labial sab, pab txo kom txo cov hlau kis. Lawv feem ntau yog siv nyob rau hauv ib cheeb tsam anterior vim lawv qhov txiaj ntsig zoo.

 

2.1.2 Kho cov kev hloov kho

Cov no tuaj yeem hloov kho cov rooj zaum ua kom haum rau tus neeg mob edite. Lawv yooj yim rau cov kws kho mob thiab cov kws tshaj lij thaum lub sij hawm twv yuav luag. Lawv feem ntau siv nyob rau hauv cov chaw phem thiab cov ntshav.

 

2.1.3 Cov nyiaj kub

Cov paub zoo rau cov kws kho zoo heev, lawv tsim nyog rau cov rooj plaub nrog qhov chaw muaj tsawg. Raws li kev hloov mus, lawv tau muab faib ua los tiv thaiv kev sib hloov thiab tsis tiv thaiv hom. Anti-rachoration abutments yog tsuas yog siv rau ib leeg-hniav lossis cement-reting hom retororations, thaum tsis-hom tshuaj tiv thaiv tau siv rau ntau chav tsev.

 

2.1.4 pob thiab Locator® abutments

Feem ntau siv rau overdentures. Lub transmucosal qhov siab yuav tsum tau tshaj li pawg sib koom ua ke, nrog Locator® Cov me nyuam yaus yuav tsum muaj 1.5 lub hli saum toj no Gingiva.

 

2.1.5 hybrid abutments

Cov no suav nrog cov qauv zoo thiab cov angled, nyob ntawm lawv cov kab mob txheeb ze rau kev cog lus. Angled abutments pab ua tiav ib txoj kev ntawm kev ntxig rau ntau kev cog hniav thiab feem ntau siv nyob rau hauv choj rov qab. Lawv tseem tuaj yeem ua cov platform rau kev tsoos tsho me ntsis.

Thaum preabricated abutments raug nqi-ua tau zoo thiab ntau yam, lawv muaj kev txwv. Lawv cov qauv transmucosal qhov siab thiab contour yuav tsis haum tus neeg mob cov nqaij mos kom haum, thiab lawv qhov kev txwv tsis pub siv nyob rau hauv cov teeb meem uas muaj qhov txawv txav lossis cov tsiaj.

 

2.2 kev txiav txim siab rau kev cai

Kev txiav txim abutments yog ua kom haum rau cov kev cog lus tshwj xeeb, kev sib tw morphology, thiab chaw editaw tod. Lawv suav nrog kev ua me me thiabCad / Cam Abutments.

Cylindrical abutments tso cai rau kev kho kom rov qab kho dua tshiab thiab tuaj yeem tsim los ntawm tus kws kho mob.

Cad / Cam Abutmentsyog tsim thiab tsim siv khoos phis tawj-kev tsim qauv computer thiab tsim khoom siv tshuab. Tom qab kev txheeb xyuas cov qauv digital, lub eleputment xub pwg yog concisely milled los ntawm cov ntaub ntawv xws li titanium alloy lossis zirconia. CAD / Cam Abutments muaj cov qauv siab, cov nqi qis dua, ua rau lawv muaj kev xaiv qis dua hauv cov aesthetic aones [^ 5].

 

3. Xaiv cov txheej txheem

Thaum xaiv los ntawm ntau yam kev tshem tawm, cov kws kho mob yuav tsum xav txog tus neeg mob tshwj xeeb cov kev mob tshwj xeeb. Ceg Tseem Ceeb Xaiv yog cummarized hauv qab no:

 

3.1 sib xyaw thiab kev sib txuas nrog cog hniav

Cov kev tshem tawm txuas mus rau kom tawg nyob rau ntau txoj kev, thiab cov tshuab sib txawv muaj kev cuam tshuam tshwj xeeb. Piv txwv li, Strebann siv ib qho kev sib txuas hla, Nobelactive siv ib lub conical hex sab hauv hex, thiab Bicon siv Morse taper. Kev xaiv xaiv yuav tsum phim cov moj khaum pluaj lub platform ua kom pom tseeb, thiab cov micbap muaj zog, thiab cov microgap tsawg, uas yog qhov tseem ceeb rau kev vam meej mus ntev. Niaj hnub no, sab hauv kev sib txuas siv platform-hloov cov txheej txheem (piv txwv li, morse taper lossis tapered ntsia hlau sib txuas) muaj ntau. Txij li thaum cov cog hniav ntawm lub platform sau cov hom kev txuas, qhov no yuav tsum tau txiav txim siab thaum npaj phiaj xwm kev phais.

 

3.2 Xaiv cov kev xaiv tshem tawm raws li kev cog lus

Kev xaiv abutment yuav tsum muaj kev cuam tshuam txog kev cog hniav qhov kev sib raug zoo thiab nws txoj kev sib raug zoo rau cov crown uas nyob ze.

Zoo tagnrho txoj hauj lwm: Preabricated abutments yuav ua rau muaj kev txaus, muab cov txiaj ntsig zoo ntawm tus nqi qis.

Kev ntsuas pa tsis zoo(Xws li, buccal dhau los yog lingual): kev txiav txim siab raug txiav txim siab yuav tsum tau them rau kev sib txawv.

Yog hais tias kev cog lus ntawm axis yog oxis yog oxis, nws cuam tshuam txawm tias cov ntsia hlau lossis rov qab khaws cia, nrog rau cov neeg xav tau rau kev ua pov thawj abred. Piv txwv li, yog tias cov ntsia hlau nkag mus rau hauv lub labent ntawm lub labial sab hauv cov aaventhetic ib qho, cov cement-khaws tseg yog nyiam. Angled Abutments (piv txwv li, 17 degree lossis 30 degree hauv "txhua-plaub" tus neeg mob) tuaj yeem kho cov kev tiv thaiv me ntsis. Txawm hais tias Angled Abutments nce kev ntxhov siab yav dhau los, kev tshawb fawb qhia cov tseem tshuav no tsis pub dhau lub plawv txwv. Ceev faj yog qhia thaum siv.

 

3.3 Raws li cov muag muag morphology

Qhov no suav nrog cov ntaub mos mos muag tuab thiab contour siab dua cov cog hniav cog.

Xaiv lub transmucosal qhov siab uas haum cov nqaij tuab rau kev nyiam huv thiab loog.

Hauv cov aesthetic aav, cov npoo ntawm cov nyom yuav tsum tau dag 1-2 hli subgingivally. Hauv cov chaw pom tsawg, zoo nkauj siab yuav ua rau muaj kev txaus siab.

Kev cai abutments tuaj yeem xa cov kev sib tsoo ntawm cov kev sib tw sib txawv, tsim kom muaj qhov profile zoo tshaj plaws profile. Cov qauv txheej txheem nrog ib lub nroog uas haum rau txoj kab cervical kuj tseem yuav muaj lub ntsej muag muag muag zoo.

 

3.4 Raws li qhov chaw muaj kev

Qhov chaw muaj peev xwm suav nrog cov interarch thiab MesiOnistal qhov ntev. Qhov chaw sib xyaw ua ke yuav tsum muaj kev txhim kho thiab kev kho tshiab zaum kawg. Txaus qhov tsis txaus (1.5-2. {{0 hli saum toj no cov teeb meem) yog xav tau rau cov khoom hloov chaw. Yog tias muaj cov kab mob ploj mus ntev, cov kaus hniav nyob ib sab yuav qaij, nqaim ntawm sab saum toj, dav hauv qab). Nws yog qhov tseem ceeb rau kev ntsuam xyuas seb puas muaj qhov chaw txaus ntawm cov kev txom nyem thiab cov hniav uas nyob ib sab.

3.5 Raws li hom kev kho

Kev kho kom pom kev tuaj yeem yog feem ntau categorized rau implant-txhawb thiab cog-mucosa-txhawb nqa rov qab
