1. Kev txhais lus ntawm cov khoom thiab kev ua haujlwm ntawm qhov chaw
Cov hlua khi orthodontic yog ib lub cuab yeej tshwj xeeb siv rau kev kho cov hniav molar hauv cov kab ke orthodontic ruaj khov, uas yog ua los ntawm cov hlau tsis xeb kho mob. Ua ib qho chaw tseem ceeb hauv cov txheej txheem orthodontic, nws cov haujlwm tseem ceeb suav nrog:
Muab lub zog ruaj khov rau lub zog orthodontic
Nqa cov khoom siv xws li cov raj buccal
Faib cov khoom thauj occlusal
Tiv thaiv cov ntaub so ntswg hniav
Daim ntawv qhia txog kev lag luam khoom siv kho hniav thoob ntiaj teb xyoo 2023 qhia tau tias cov khoom siv khi hniav tseem khaws cia 28% ntawm kev siv ntawm cov khoom siv kho hniav, tshwj xeeb tshaj yog rau cov teeb meem nyuaj uas xav tau kev khi ruaj khov.
2. Cov Txheej Txheem Tseem Ceeb
Cov yam ntxwv ntawm cov khoom siv
Siv 316L kho mob stainless hlau
Tuab: 0.12-0.15 hli
Lub zog tawm los ≥ 600MPa
Tus nqi ntev ≥ 40%
Tsim Qauv
Cov txheej txheem loj ua ntej (feem ntau siv rau # 18-32 hauv thawj cov molars)
Kev ua kom pom tseeb ntawm qhov chaw occlusal
Tsim qauv wavy ntawm gingival margin
Lub raj xa dej buccal / khawm lingual uas tau vuam ua ntej
Kev Kho Mob Nto
Kev siv hluav taws xob (qhov roughness ntawm qhov chaw Ra≤0.8μm)
Kev kho mob tso tawm tsis muaj nickel
Txheej tiv thaiv cov plaque (xaiv tau)
3. Kev Tshawb Fawb Txog Cov Kev Zoo ntawm Kev Kho Mob
Cov khoom siv kho tshuab zoo heev
Muaj peev xwm tiv taus 500-800g orthodontic zog
Qhov tsis kam rau kev hloov pauv yog 3 npaug siab dua li ntawm hom kev sib txuas
Haum rau cov kev xav tau kho tshuab muaj zog xws li kev sib txhuam ntawm cov leeg nqaij
Kev ruaj khov mus sij hawm ntev
Lub voj voog siv nruab nrab yog 2-3 xyoos
Kev ua tau zoo heev ntawm ntug sealing (microleakage <50μm)
Kev tiv thaiv xeb zoo heev
Kev hloov kho rau cov xwm txheej tshwj xeeb
Cov hniav uas muaj enamel hypoplasia
Kev kho dua tshiab ntawm thaj chaw loj ntawm cov hniav sib tsoo
Kev xav tau rau kev phais mob orthognathic anchoring
Cov xwm txheej uas xav tau kev txav mus los sai
4. Kev hloov pauv ntawm cov thev naus laus zis niaj hnub
Kev siv tshuab digital los hloov kho
Kev luam theej qhov ncauj thiab kev luam ntawv 3D
Kev hloov kho qhov tuab ntawm tus kheej
Kev rov ua dua qhov tseeb ntawm cov qauv ntawm qhov chaw occlusal
Hom kev txhim kho biologically
Lub nplhaib uas tso cov tshuaj fluoride tawm
Cov txheej txheem tiv thaiv kab mob silver ion
Ntug iav bioactive
Lub kaw lus siv tau yooj yim
Lub raj xa dej buccal uas tau teeb tsa ua ntej
Cov cuab yeej rub tawm tau
Kev tsim tus kheej xauv
"Cov thev naus laus zis niaj hnub no tau hloov zuj zus los ntawm kev kho kom yooj yim mus rau kev daws teeb meem uas suav nrog kev sib raug zoo ntawm cov khoom siv, kev tswj hwm, thiab kev kho mob tiv thaiv. Thaum ua kev xaiv kho mob, nws yog ib qho tsim nyog yuav tsum xav txog cov mob hniav, cov phiaj xwm kho hniav, thiab tus neeg mob qhov ncauj ib puag ncig. Nws raug pom zoo kom siv cov khoom lag luam uas tsim los ntawm digital kom ua tiav cov txiaj ntsig zoo tshaj plaws."
– Xibfwb Wang, Tus Thawj Coj ntawm Lub Koom Haum Orthodontic Suav
Cov hlua khi hniav, ua ib yam thev naus laus zis qub uas tau lees paub ntau tshaj ib nrab xyoo pua, tseem niaj hnub rov ua dua tshiab nrog kev siv digital thiab biomaterial technology. Nws cov txiaj ntsig kho tshuab uas tsis muaj qhov hloov pauv tau ua rau nws tseem nyob hauv txoj haujlwm tseem ceeb hauv kev kho mob orthodontic nyuaj, thiab nws yuav txuas ntxiv pab cov chaw kho mob orthodontic los ntawm cov qauv meej dua thiab tsawg kawg nkaus yav tom ntej.
