Tsis muaj qhov "zoo tshaj" cov khoom siv kho hniav, tsuas yog cov khoom tsim nyog rau koj tus kheej qhov ncauj. Nyob ntawm koj qhov ncauj qhov ntswg, qhov chaw ntawm cov hniav uas ploj lawm, koj qhov kev xav tau occlusal, thiab koj cov peev nyiaj, cov ntaub ntawv sib txawv muaj lawv tus kheej zoo.
1. Cov hniav sab nrauv: Kev zoo nkauj ua ntej → Zirconia ceramic pom zoo
Qhov zoo: Ntuj thiab translucent xim, tsis muaj xim hlau grey kab, haum rau cov neeg mob uas muaj cov pos hniav nyias los yog cov neeg uas nthuav tawm ntau thaum luag ntxhi.
Haum rau: Cov neeg uas xav tau kev zoo nkauj zoo nkauj lossis hlau tsis haum.
Ceebtoom: Cov tawv nqaij me me, tsis haum rau qhov chaw molar.
2. Cov hniav tom qab: Ua haujlwm ua ntej → Qib 5 titanium alloy (Ti-6Al-4V) pom zoo
Qhov zoo: Lub zog muaj zog ntau dua 30% siab dua cov titanium ntshiab, muaj zog qaug zog, thiab tuaj yeem tiv taus ntev - lub sij hawm zom zom.
Haum rau: Cov neeg uas muaj zog tom heev, cov pob txha mos, lossis cov uas xav tau kev thauj khoom tam sim.
3. Rau cov pob txha tsis txaus → Hydrophilic qib 4 titanium los yog titanium-zirconium alloy yog pom zoo.
Qhov zoo: ceev osseointegration, zoo pib ruaj khov, thiab txo qhov xav tau rau pob txha grafting phais.
Cov neeg sawv cev hom: Swiss ITI (Straumann), Swedish Nobel Biocare.
Cov ntaub ntawv txhawb nqa: Hydrophilic nto kev kho mob tuaj yeem ua rau lub sijhawm osseointegration luv mus rau 3-4 lub lis piam.
4. Rau cov neeg uas muaj hlau tsis haum lossis biocompatibility rhiab heev → Xaiv zirconia lossis PEEK.
Zirconium oxide: Txhua yam -ceramic khoom, tsis muaj ion tso tawm, biocompatibility zoo heev.
PEEK (polyetheretherketone): Elastic modulus ze rau cov pob txha cov ntaub so ntswg, buffers occlusal rog, tab sis feem ntau yog siv rau kev kho ib ntus.
5. Rau cov neeg siv nyiaj tsawg → Hauv tsev / Kaus Lim Kauslim qib 4 titanium yog tus nqi - kev xaiv zoo.
Hauv tsev ntshiab titanium: Nqe kwv yees li 5000-8000 RMB / hniav, kev kho mob siab npaum li cas, haum rau cov neeg uas muaj pob txha alveolar zoo.
Kauslim hom (xws li Dentium thiab Osstem): 7,000-10,000 yuan ib thooj, nrog rau cov cuab yeej paub tab thiab kev ua lag luam dav dav.
