Nyob rau hauv cov teb ntawm edentulous kev kho kom rov kho dua, cov kab txhab kev tshem tawm cov hniav looj kab (feem ntau hu ua cov kab mob uas tshem tau) yog cov qauv siv feem ntau. Lawv siv cov hniav thiab cov mucosa thiab pob txha npog lub hauv paus rau kev txhawb nqa, cia siab rau ntawm cov ntawv qhia chaw thiab lub hauv paus rau kev khaws cia. Cov hniav cuav rov qab tsim daim foos thiab ua haujlwm ntawm cov hniav, thaum lub hauv paus khoom siv rov qab kho cov morphology ntawm alveolar disgris thiab mos nqaij ntswg tsis zoo. Cov neeg mob tuaj yeem tshem tawm thiab hnav cov pob txha cajqheej, muab kev xaiv kho kom yooj yim rau cov neeg mob.
Bracket kev faib tawm thiab cov yam ntxwv
Raws li cov khoom siv, cov khoom siv uas nquag muaj nyob ntawm lub khw muaj peek, ntshiab titanium, thiab cobalt-chromium. Txhua cov ntaub ntawv muaj nws tus kheej zoo thiab qhov tsis zoo. Peek thiab dawb huv Titanium tau zoo intraoral compatibility, tab sis yog tus nqi. Cobalt-chromium braces muaj ntau tus nqi pheej yig, tab sis tuaj yeem muaj lub zog txawv teb chaws lub cev hnov. Nrog kev ua lag luam kev txhim kho thiab kev txhim kho hauv cov khoom siv thev naus laus zis, titanium alloy braces yog ua kom paub tab zuj zus thiab muaj koob npe nrov ntawm cov neeg siv khoom. Kev siv thoob plaws ntawm titanium alloys hauv kev kho hniav
Titanium alloys tau siv dav hauv daim teb kho hniav. Lawv tuaj yeem siv rau hauv kev tsim cov khoom sib xyaw ua ke ntawm ntau yam khoom siv dag, cov pob txha ua pob, cov hniav looj, kho hniav, thiab txuas ntxiv. Titanium Alloy tau hais hauv cov kab lus no muaj cov tshuaj lom neeg muaj pes tsawg ntawm titanium (89%), uas tau ze rau Titanium. Cov seem ntawm cov khoom thiab lawv cov ntsiab lus yog kwv yees li ntawm: Allection (Al): 5.5-6.5%; Vanadium (v): 3.5-4.5%; Cov pa (O): tsawg dua lossis sib npaug rau 0.13%; hlau (FE): tsawg dua lossis sib npaug rau 0.25%; nitrogen (n): tsawg dua lossis sib npaug rau 0.03%; Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0.08%; Hydrogen (H): Tsawg dua lossis sib npaug nrog 0.008% (cov tsis sib txawv raws li qhov tseeb tiag).
Qhov zoo ntawm titanium alloys raws li tib neeg kev cog lus
Titanium alloys muaj ntau yam tseem ceeb ua tib neeg kev cog lus:
Lub teeb yuag: nrog qhov ceev ntawm 4.5 g / cm³ (ntawm 20 degree), cog kom txo lub cev thauj khoom thiab muab kev nplij siab dua rau tus neeg mob. Qis Elastic Modulus: Tom qab cog qoob loo, nws zoo dua li lub cev pob txha, pab txhawb cov pob txha uas thaiv cov pob txha ntawm cov pob txha ntawm kev noj qab haus huv.
Tsis muaj sib nqus: tsis muaj kev sib nqus los ntawm hluav taws xob teb thiab cua hlob heev, kom muaj kev nyab xeeb thaum siv cov kev pheej hmoo tshwj xeeb hauv ib puag ncig tshwj xeeb.
Tsis muaj tshuaj lom: cog hniav tsis muaj tshuaj lom cov kev mob tshwm sim, muab kev tiv thaiv kom tau kev tiv thaiv rau tus neeg mob.
High corrosion Kuj: raws li bioinert hlau cov khoom, ua rau tib neeg cov ntshav, ua rau tib neeg cov ntshav thiab cov nqaij, thiab nthuav tawm lub neej ntawm kev cog lus.
Lub zog siab thiab tawv: Kev cog tawm sab laug hauv tib neeg lub cev ntev thiab muaj kev khoov, nyem, thiab cov leeg leeg. Lub zog siab thiab tawv ntawm titanium alloys tau raws li cov tseev kom muaj thiab ua kom pom tseeb tias cog neeg ruaj khov.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
