Dab tsi yog Hom Dental Implants?

Cov qauv kev txhawb nqa ruaj khov rau kev cog hniav-txhawb nqa hniav sib txawv ntawm cov khoom siv kho hniav ib txwm muaj.

Lawv tuaj yeem muab faib ua cov khoom siv kho hniav uas txhawb nqa cov hniav, npog cov hniav cog hniav, thiab tshem tau ib feem ntawm cov hniav nyiaj hniav kub txhawb nqa raws li txoj kev kho.

Fixed dentures yog ib txoj hauv kev nrov los kho cov implants. Sab saum toj ntawm cov hniav cog-txhawb nqa cov hniav yog txuas rau lub abutment siv cov nplaum los yog cov ntsia hlau.Qhov no restores cov hniav uas ploj lawm daim ntawv anatomical thiab physiological muaj nuj nqi.

Cov neeg mob tsis tuaj yeem tshem cov hniav cuav ntawm lawv tus kheej tom qab implantation. Txoj kev no muaj ntau yam kev siv, zoo ib yam li cov hniav ntuj, muab kev hnav zoo, ruaj khov, thiab kev txhawb nqa.

Cov txheej txheem no tuaj yeem siv los hloov ib lossis ntau cov hniav uas ploj lawm lossis txawm tias tag nrho cov hniav hniav.

Hom kev cog-txhawb nqa prosthesis no yog siv nyob rau hauv cov ntaub ntawv uas muaj cov pob txha loj heev resorption nyob rau hauv tag nrho cov koov (los yog ib nrab koov) vim hniav poob.

Nws yog siv nyob rau hauv lub puab tsaig edentulous uas yuav tsum tau 2 mus rau 4 hniav implants. Txij li thaum siv cov cog cog ib leeg tsis txaus los txhawb nqa qhov ruaj khov-arch prosthesis nyob rau hauv cov nqe lus ntawm kev ruaj ntseg thiab zom ua haujlwm, thiab vim yog cov pob txha tseem ceeb ntawm cov ntaub so ntswg nqus, lub hauv paus resin yog siv los kho cov pob txha uas ploj lawm thiab txhim kho lub ntsej muag zoo nkauj hauv qhov no. implant-txhawb prosthetic restoration.

Nyob rau hauv cov ntaub ntawv ntawm tag nrho-arched implant-txhawb prostheses, lub implant abutments yuav tsim nrog ntau yam attachments, xws li clasps, bar attachments, pob caps, sib nqus attachments, thiab lub tes tsho crowns.

Covered hniav hniav yog qhov tseem ceeb tshem tawm cov hniav nyob rau hauv uas lub moj khaum ntawm cov hniav uas tshem tau npog cov hauv paus hniav, crowns, thiab implants thiab tso siab rau cov qauv no rau kev txhawb thiab stability.Cov neeg mob tuaj yeem tshem tawm thiab hnav lawv tus kheej, ua rau lawv haum rau cov neeg uas muaj cov hniav ploj tag los yog dav heev.

Hom kev kho dua tshiab no tsis tshua muaj siv thiab feem ntau pom nyob rau hauv cov xwm txheej uas qhov chaw cog qoob loo tau sib txawv ntawm qhov chaw qub los yog thaum muaj cov khoom cog tsis txaus.

Hauv cov xwm txheej uas cov neeg mob tsis txaus siab lossis tsis tuaj yeem ua tiav qhov kev cog qoob loo, cov khoom cog uas twb muaj lawm yog siv los ua cov qauv kev txhawb nqa rau cov hniav uas tshem tau ib nrab.

Txoj kev no yog tsim los tshem tawm qhov mob uas cuam tshuam nrog lub dab dej ntawm cov hniav uas tshem tau.

Kev xaiv cov txheej txheem kho kom tsim nyog yog qhov tseem ceeb tshwj xeeb raws li cov xwm txheej tshwj xeeb thiab qhov twg ntawm cov hniav ploj.Muaj ntau yam los xav txog, thiab hauv kev sib tham yav tom ntej, peb yuav maj mam txheeb xyuas cov xwm txheej no.

Kev cog hniav yog ib feem muab tso rau hauv cov pob txha alveolar thiab tsuas yog cov khoom tso rau hauv tib neeg lub cev thaum cog hniav. Yog li ntawd, kev xaiv cov khoom yog qhov tseem ceeb. Cov khoom siv cog qoob loo yuav tsum tsis muaj tshuaj lom, tsis yog-allergenic, tsis yog carcinogenic, thiab tsis-teratogenic.

Lawv yuav tsum muaj biocompatibility zoo, corrosion kuj, hnav tsis kam, thiab zoo heev mechanical zog.

Kev cog hniav tuaj yeem raug cais raws li lawv cov khoom siv rau hauv cov khoom siv hlau, cov khoom cog cog qoob loo, cov pa roj carbon implants, cov cog cog polymer, thiab cov cog cog qoob loo.

Txij li thaum Branemark tau tshaj tawm txoj kev xav ntawm osseointegration, ntshiab titanium thiab titanium alloys yog cov khoom siv zoo tshaj plaws rau kev cog hniav hauv qhov ncauj. Kev tshawb fawb tau pom tias cov titanium ntshiab muaj biocompatibility zoo heev thiab corrosion kuj, nrog rau cov khoom zoo heev, xws li hardness, tensile zog, yield zog, thiab qaug zog zog. Cov khoom no ua tau raws li qhov yuav tsum tau ua ntawm kev cog hniav, thiab cov titanium ntshiab tau siv dav los ua cov khoom cog hauv cov chaw kho mob nrog cov txiaj ntsig zoo.

Qhov tsis zoo: Txawm hais tias kev siv tshuaj kho mob ntawm cov ntshiab titanium thiab titanium alloy implants, tseem muaj kev txwv. Hlau thiab nws cov alloys muaj lub zog siab, tab sis lawv cov Young's modulus yog qhov loj, uas ua rau muaj kev ntxhov siab tiv thaiv.

Feem ntau yog tsim los ntawm cov ntaub ntawv xws li zirconium oxide. Ceramics muaj qhov zoo nkauj zoo nkauj, nrog cov xim zoo ib yam li cov hniav ntuj, thiab pom zoo biocompatibility. Cov kws tshawb fawb tau tshawb fawb txog kev siv cov ceramics ua cov khoom cog hauv kev kho mob. Cov chav kawm ntawm cov ntaub ntawv no yog tus cwj pwm los ntawm kev ua haujlwm siab, kev tiv thaiv corrosion, tsis ua rau khaus, tsis muaj tshuaj lom, thiab cov ntaub so ntswg compatibility.

Qhov tsis zoo: Cov ntaub ntawv kho mob mus sij hawm ntev tseem tsis muaj cov ntaub ntawv ceramic xws li zirconia. Muaj kev tsis sib haum xeeb txog cov teeb meem xws li hnav, crystalline degradation, tawg propagation, thiab brittle fracture thaum siv los ua cov khoom cog hniav.

Cov qeb no feem ntau suav nrog cov ntaub ntawv xws li cov iav iav thiab cov pa roj carbon isotropic qis. Cov ntaub ntawv no muaj cov tshuaj lom neeg ruaj khov thiab tsis yooj yim biodegradable. Txawm li cas los xij, lawv yog nkig thiab yooj yim rau discoloration.

Cov ntaub ntawv polymeric muaj xws li acrylate thiab polytetrafluoroethylene. Cov qauv tshuaj ntawm cov ntaub ntawv no zoo ib yam li ntuj polymers pom nyob rau hauv tib neeg lub cev, ua rau lawv ntau biocompatible. Txawm li cas los xij, kev tshawb fawb ntxiv yog xav tau los tshawb xyuas lawv lub zog thiab kev ua haujlwm osteoconductive. Tsis tas li ntawd, lawv muaj kev cuam tshuam rau biodegradation, uas yuav ua rau gingival irritation.

Cov ntaub ntawv sib xyaw feem ntau sib xyaw ua ke ntau yam ntaub ntawv hais los saum toj no kom ua tiav lawv cov txiaj ntsig zoo thiab ua tau raws li qhov xav tau ntawm tib neeg lub cev.

Kev cog hniav muaj xws li ntau yam kev cog hniav, suav nrog Kauslim Dentium thiab Osstem systems, Swedish Nobel system, German Bego system, American 3I system, Swiss ITI system, thiab domestically tsim tshuab xws li Bacomed hauv Suav teb.

Lub hom phiaj ntawm kev cog qoob loo yog qhov kev sib tham ntau hauv ib tsab xov xwm dhau los-Dab tsi yog Hom Tshuaj Kho Hniav Zoo Tshaj Plaws? Vim li cas?

Lwm qhov kev faib tawm ntawm cov cog cog yuav raug tham los ntawm Kev Coj Tus Cwj Pwm hauv qhov teeb meem tom ntej.
