Kub yog ib qho ntawm thawj cov hlau uas siv los ua tshuaj. Nws yog nrog nws cov kev siv uas prosthetics nyob rau hauv kev kho hniav pib, cov hniav kub nyob rau hauv ancient sij hawm tau suav hais tias yog ib qho khoom kim heev thiab cim lub siab tshaj plaws ntawm tib neeg kev noj qab nyob zoo, nws txoj hauj lwm tseem ceeb hauv zej zog.
Kev thov kub hauv kev kho hniav
Nyob hauv kev kho hniav niaj hnub no, nws tau siv dav hauv kev tsim ntau yam kev kho hniav:
- khoom cog;
- ib leeg abutments;
- stump thiab kho hniav;
- braces;
- prostheses nrog clasp thiab telescopic fixation system;
- metal-ceramic crowns.
Cov khoom ntawm kev kho hniav kub alloys
Prosthetics nrog kub tau dhau los ua dav vim yog cov khoom tshwj xeeb ntawm noble hlau:
- Cov hlau nws tus kheej thiab nws cov alloys tuaj yeem yooj yim polished, uas yog qhov tseem ceeb tshwj xeeb tshaj yog thaum tsim cov npoo ntawm cov pob qij txha, uas tso cai rau lawv kom haum snugly tiv thaiv cov pos hniav yam tsis muaj kev pheej hmoo ntawm kev puas tsuaj rau cov ntaub so ntswg thiab kev loj hlob ntawm cov pos hniav. cov txheej txheem carious hauv qhov chaw sib cuag nrog cov hniav noj qab haus huv.
- Cov hniav kub tsis oxidize thiabtsis pleev xim rau, tiv taus corrosion.
- Cov hlau no tsis ua rau tus neeg intolerance thiab galvanic effect.
- Nws tsis ua rau cov quav hniav hauv cov hniav.
- Ntau fluidity ntawm kub-bearing alloys ua rau nws muaj peev xwm ua tau siab precision nyob rau hauv kev tsim ntawm prosthesis designs.
- Thaum siv kub, qhov zoo nkauj ntawm lub puab tsaig txhim kho, nws muab cov txheej txheem ceramic ua lub ntuj ntxoov ntxoo uas tsis txawv ntawm cov xim ntawm cov hniav noj qab haus huv.
Indications thiab contraindications
Kev cog hniav yog xav tau nyob rau hauv cov xwm txheej hauv qab no:
- thaum kho lawv cov duab anatomical thiab ua haujlwm;
- thaum kho qhov mob hnyav heev thiab yuav tsum tau ntxiv dag zog rau cov hniav;
- muab qhov zoo nkauj ntawm qhov ncauj;
- thaum kho cov hniav tom qab;
- nyob rau hauv lub xub ntiag ntawm parafunctional cwj pwm - sib tsoo, nyuaj clenching.
Kev txhim kho prostheses tsis ua ntawm:
- kuaj mob hlwb;
- kuaj pom tus kab mob mob ntev;
- thaum cev xeeb tub;
- tus neeg mob qis dua 16 xyoo.
Kev tsim cov kaus mom
Cov khoom zoo nkauj ntawm cov khoom siv zoo li no tau nce ntau vim yog siv cov khoom siv ceramic. Yog hais tias kub crowns yuav tsum tau muab tso rau ntawm cov hniav anterior, ces lub moj khaum ua los ntawm ib tug alloy uas muaj nuj nqis hlau yuav tsum tau veneered nrog ib tug ceramic loj los txhim kho lub zoo nkauj zog. Translucent los ntawm qhov txias dawb ntawm cov ceramic, cov kub muab cov hniav sov thiab yellowish tint, tsim kom muaj sia nyob thiab zoo nkauj.
Thaum nrum cov yas, cov kub ntshiab tsis siv. Txhawm rau muab lub zog uas yuav tsum tau ua rau cov pob qij txha, palladium thiab platinum tau ntxiv me me rau cov hlau. Cov yas zoo li no tuaj yeem siv tau ntev yam tsis poob lawv cov khoom.
Tsis ntev los no, cov kaus mom dai kom zoo nkauj nrog cov pob zeb zoo nkauj lossis cov duab kub, nrog rau lawv cov qauv tsim tawm, uas yog tshiab hauv kev kho hniav, tau txais txiaj ntsig loj heev. Prosthetics nrog cov yas tshem tau yog txiav txim siab, es, los ntawm kev xav ntawm tus neeg mob dua li qhov tsim nyog. Cov qauv zoo li no tau nruab rau ntawm tus hniav noj qab haus huv, thiab yog li ntawd lawv muaj qhov tuab me me.
txiaj ntsig ntawm cov hniav nyiaj hniav kub
Kev teeb tsa ntawm cov hniav thiab cov yas ua los ntawm cov kub muaj nws qhov txiaj ntsig tsis zoo tshaj lwm cov ntaub ntawv tseem siv hauv cov hniav hniav:
- kev sib raug zoo nrog cov ntaub so ntswg ntawm qhov ncauj, uas tshem tawm qhov tshwm sim ntawm kev ua xua thiab khaus;
- tsis muaj txawm tias me ntsis impurities ntawm ib qho carcinogenic compounds;
- muaj zog alloy, ua cov hniav kub yuav luag tsis tuaj yeem tawg lossis puas;
- vim qhov muag ntawm cov hlau, cov hniav antagonist tsis raug puas tsuaj, vim tias ob qho tib si cov hniav hniav thiab cov hniav uas nyob ib puag ncig yuav raug tshem tawm yuav luag ib txhij;
- coefficient ntawm thermal expansion ntawm hlau thiab dentintag nrho coincides, muaj yuav luag tag "coagulation" ntawm prosthesis thiab hniav.
Qee cov kws tshawb fawb nyiam ua cov kab mob bactericidal rau kub, txawm tias tsis muaj pov thawj tshawb fawb txog qhov no, txawm li cas los xij, nrog rau kev tawm tsam.
Disadvantages of Precious Metal Dentures
Ntxiv rau qhov tseem ceeb, kev cog hniav ua los ntawm kub kuj muaj qhov tsis zoo:
- nrawm txaus abrasion;
- tus nqi siab ntawm cov khoom siv thiab kev teeb tsa ntawm prostheses;
- hloov tswv yim txog kev zoo nkauj ntawm kub prosthetics.
Cov tswv yim niaj hnub hais txog kev zoo nkauj thiab kev zoo nkauj ntawm lub qhov ncauj kab noj hniav hais txog kev teeb tsa cov hniav nyiaj hniav kub tsuas yog hauv qhov tob ntawm lub qhov ncauj. Nws ntseeg tau tias ntawm cov hniav pom thaum lub luag nyav lossis kev sib tham, cov hlau no zoo li tsis zoo thiab tsis zoo.

Cov hniav kub tsis tas yuav muaj kev saib xyuas tshwj xeeb, tab sis muaj qee qhov yuav tsum tau ua:
- txhuam lawv tsawg kawg ob zaug hauv ib hnub nrog txhuam hniav thiab tshuaj txhuam hniav.
- Txhawm rau tiv thaiv cov kab mob tartar ua rau cov pos hniav thiab kab noj hniav, nws raug nquahu kom siv cov tshuaj txhuam hniav los ntxuav qhov sib txuas ntawm cov pos hniav thiab cov hniav.
- khoom noj khoom haus, noob thiab txiv ntseej yuav tsum zam, thiab yuav tsum zam kom txhob raug ntsia thawv tom.
- Nws yog txwv tsis pub coj koj cov hniav thiab zom lawv. Yog hais tias qhov no tshwm sim involuntarily nyob rau hauv ib tug npau suav, ces thaum hmo ntuj nws yog pom zoo kom hnav tiv thaivkhoom siv.
Tus nqi ntawm cov hniav kub yog dab tsi?
Nyob rau hnub no, kev cog qoob loo yog ib qho kev xaiv zoo rau cov neeg uas xav rov qab los ntawm lawv qhov qub zoo nkauj luag ntxhi thiab zam qhov teeb meem zom.
Tus nqi ntau npaum li cas los txhim kho cov hniav kub? Lawv tus nqi nyob ib txhij ntawm ntau yam, ob qho tib si rau txhua tus neeg thiab ntau rau txhua tus, thiab tuaj yeem nyob ntawm 7 txog 55 txhiab rubles Lavxias.
Yog peb tham txog cov txheej txheem prosthetic nws tus kheej, ces nws tus nqi nyob ntawm:
- nyuaj hauv kev phais kev teeb tsa;
- tus nqi ntawm tus prosthesis nws tus kheej. Nws yuav tsum to taub tias tus nqi ntawm ib gram ntawm kub yog kwv yees li 65 euros, ceramics thiab cov khoom uas ua rau cov hlau kuj tsis yog pheej yig;
- tus yam ntxwv ntawm tus qauv ntawm cov hniav uas lub kaus mom lossis cov hniav yog tsim - nws qhov loj me, cov duab thiab, yog li ntawd, loj.
Kuj, yam ntxiv, xws li:
- xwm txheej thiab koob meej ntawm chaw kho hniav, nws qhov chaw;
- qib kws kho mob tsim nyog;
- tsim lub teb chaws ntawm cov khoom siv rau kev tsim cov prostheses thiab lawv qhov zoo. Lub geography yog dav heev - los ntawm lub teb chaws Yelemees los yog Ixayees mus rau Kauslim Teb thiab lub teb chaws USA, muaj txawm Russia manufacturers.
Tsuas yog suav nrog tag nrho cov xwm txheej no, nws tuaj yeem kwv yees tus nqi ntawm kev tsim khoom thiabinstallation ntawm kub hniav los yog crowns. Nws yuav muaj txiaj ntsig kom paub tias kev teeb tsa ntawm ib tus hniav tsuas yog kim heev, thiab thaum xaj ntau lossis tag nrho cov hniav ib zaug, koj tuaj yeem tau txais luv nqi ntawm ob qho tib si cov ntaub ntawv thiab kev ua haujlwm ntawm tus kws kho mob.
Txawm li cas los xij, ua ntej txiav txim siab, koj yuav tsum paub ua ntej tus nqi hauv ntau lub tsev kho mob thiab, piv cov ntsiab lus, tus nqi thiab kev tsim nyog ntawm tus kws tshaj lij, xaiv ib qho ntawm lawv.
