Cov kab nrib pleev yog hu ua non-removable structures, uas yog siv los txhim kho kev ua txhaum ntawm tib neeg tom. Cov no yog cov khoom siv ua kom ruaj ruaj ntawm cov hniav nrog cov kua nplaum tshwj xeeb, thiab tom qab ntawd muaj kev sib txuas ntawm ib qho uas "muaj lub cim xeeb", uas yog, lawv rov qab mus rau lawv daim ntawv thaum muaj cua sov. Cov kev hloov ntawm qhov chaw ntawm cov hniav nyob hauv lub qhov ncauj kab noj yog ua tiav kev siv lub zog ntawm lub zog tawv. 15 xyoo dhau los, kev zawm hniav yog ib qho tshiab thiab paub ua li cas, tab sis tam sim no qhov kev xaiv yog qhov zoo - hlau lossis sapphire - rau txhua lub hnab.
Dab tsi ua sapphire braces zoo li?
Ntawm chav kawm, thawj kev nyuaj siab nyob deb ntawm zoo meej nyob rau hauv tsos. Tsheej lab ntawm cov neeg tsis tau twv kom raug kho tom los ntawm qhov zoo nkauj vim tsis zoo nkauj zoo nkauj. Ntau txhiab leej menyuam yaus tau txais cov khoom ntxiv, siv ob peb xyoo xws li cov hluas nyuaj rau lub sijhawm nrog cov txhaws hlau rau ntawm lawv cov hniav. Tab sis, qhov zoo tshaj plaws, kev kho hniav ncaj nraim los ntawm kev xa tawm thiab cov ciaj ciam thiab cov kev zoo nkauj niaj hnub tuaj yeem tsis pom ntawm cov hniav.
Qhov zoo nkauj tshaj plaws ntawm lawv yog sapphire braces. Rau lawv cov khoom siv, tib cov iav ci ntawm sapphire yog siv, vim li ntawd, kev zawm hniav yuav luag pob tshab thiab imperceptible thaum mounted rau cov hniav. Ntaus ntawm sapphire bracket-systems yog cov nram qab no:
- lawv yog pob tshab;
- Tsis txhob xaub thaum noj mov lossis xim dej;
- ntawm lawv qhov chaw tsis muaj pob txob, uas txo txoj kev pheej hmoo ntawm kev sib tw ntawm cov hniav uas muaj kev sib koom tes (txawm tias, tsis tas yuav tsim nyog rau cov khoom txom ncauj);
- kev hnyav siab ua haujlwm;
- tsis txhob cuam tshuam nrog kev ua haujlwm ntawm kev hais lus;
- tsis txhob ua rau tsis kaj siab nyob hauv qhov ncauj;
- me me, zoo tsim, hloov npoo;
- txhim khu kev qha system ntawm fastening mus rau enamel.
Qhov feem ntau pom yog sapphire braces nrog ib tug dawb Arc. Feem ntau, txoj kev kho qhov teeb meem yog xim, xim hlau thiab, txawm tias thaum sapphire pob tshab kev sib txuas, nws pom ntawm cov hniav. Tab sis niaj hnub orthodontics tsim tshwj xeeb arcs nrog ib tug zoo nkauj dawb txheej, uas ua rau tus tsim yuav luag imperceptible rau tag nrho cov sij hawm hnav.
Disadvantages ntawm kev zawm hniav
Ntawm chav kawm, tsis muaj dab tsi yog zoo meej, thiab transparent sapphire braces, hmoov tsis, ib yam nkaus thiab. Lawv qhov teeb meem loj tshaj plaws yog kev tsis sib haum xeeb. Yog li ntawd, tag nrho tib yam, nws tsim nyog yuav tsum tau ceev faj thaum lub sij hawm khoom noj kom tsawg thiab tsis txhob siv zog ntau dhau thaum muab tom tej zaub mov. Qhov thib ob qhov teeb meem loj ntawm cov hlua khi no yog lawv cov nqi siab. Alas, ntshiab monocrystalline sapphire tsis yog kim Library. Tab sis tag nrho lwm qhov zoo tseem dua lub installation ntawm sapphire kev zawm hniav.
Yuav ua li cas muaj ntau npaum li cas sapphire braces yuav tsum tau hnav yog ib qho tseem ceeb uas yog kev txhawj xeeb rau txhua tus neeg uas tau txiav txim siab los kho qhov tom. Yuav tsis muaj ib qho lus teb uas tsis muaj tseeb, txhua yam nyob ntawm qhov xwm txheej. Tab sis feem ntau yog lub sij hawm ntawm hnav cov tsiaj txhu zoo nkauj
Txawv ntawm cov zuag ntsis plaub hau thiab zas ntsej muag
Thawj qhov sib txawv nruab nrab ntawm ob feem nrov bracket systems nyob rau hauv tsos. Cov zuag paj nruag yog dawb, thiab sapphire, raws li peb twb pom tawm - pob tshab. Ceramic txhaj cov polycrystalline aluminium oxide, uas muab dua lub dag lub zog ntawm xws li kev zawm hniav nyob rau hauv kev sib piv nrog sapphire. Ib qho tseem ceeb sib txawv yog tus nqi - cov ntxhuav sawv daws yuav pheej yig tshaj li sapphire ones. Yog li sapphire braces zoo nkauj zoo nkauj ntawm cov hniav dawb zoo, ua ntej lawv siv, ntau tus neeg mob tau pom zoo kom ua hniav dawb . Lub zuaj zawg yuav ua rau pom ntawm qhov txig ntawm txhua qhov ntxoov ntxoo, vim hais tias qhov ntxoov ntxoo ntawm ceramics yuav raug kho dua.
