Hauv txoj kev mus rau lub luag nyav zoo meej, cov brackets thiab cov xov hlau tsuas yog ib nrab ntawm kev sib ntaus sib tua xwb.Cov roj hmab kho hniav, feem ntau hu uacov roj hmab orthodontic, yog cov phab ej uas tsis muaj npe nrov ntawm kev kho hniav. Thaum cov xov hlau sib dhos cov hniav hauv lub qhov nkhaus, cov roj hmab muab lub zog sib txuas uas tsim nyog los sib dhos lub puab tsaig sab saud thiab sab qis.
Technically hu uacov roj hmab intermaxillary, cov khoom siv kho mob no yog tsim los siv qhov siab sib xws hauv cov kev taw qhia tshwj xeeb. Raws li cov qauv kho mob orthodontic, cov hlua no pab txhawb "lub zog sib txuas," uas yog lub hauv paus tseem ceeb rau kev kho qhov tsis sib xws (tom misalignments). Tsis muaj qhov nro uas muab los ntawm cov khoom zoocov roj hmab orthodontic, kev kho cov teeb meem xws li overbites, underbites, lossis crossbites yuav luag tsis yooj yim sua los ntawm cov khoom siv kho tas li.
Txhais Cov Cheebtsam Tseem Ceeb ntawm Elastic Therapy
- Khoom siv:Feem ntau yog ua los ntawmroj hmab kho mob qib orthodonticlos yog cov roj hmab zoo. Rau cov neeg mob uas muaj kev tsis haum tshuaj,cov roj hmab kho hniav uas tsis muaj latexyog tus qauv kev lag luam los tiv thaiv kev ua xua.
- Lub Hom Phiaj:Txhawm rau muab lub zog "active" uas xav tau raucov khoom siv kho tomua haujlwm hla lub maxillary (sab saud) thiab mandibular (qis dua).
- Kev Ntsuas Zog:Ntsuas hauv ounces (oz) lossis grams (g), uas sawv cev rau qhov kev nruj uas siv thaum txoj hlua raug ncab mus txog peb npaug ntawm nws txoj kab uas nws xoob.
Cov Khoom Siv Kho Hniav Kho Tau Qhov Overbite lossis Underbite Li Cas?
Cov txheej txheem ntawmcov khoom siv kho tomvam khom rau qhov kev teb ntawm lub cev ntawm kev kho pob txha. Thaum tus kws kho hniav txuas ib daim roj hmab los ntawm tus dev sab saud mus rau tus hniav hauv qab, qhov kev nruj tas mus li ua rau cov hlwb ua haujlwm hauv lub puab tsaig, ua rau cov hniav hloov mus rau hauv qhov chaw noj qab haus huv.
Chav Kawm II vs Chav Kawm III Elastics: Kev Sib Piv ntawm Cov Qauv
Yuav kom nkag siab txog koj txoj kev kho mob li cas, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov kev teeb tsa sib txawv ntawmcov roj hmab intermaxillary.
| Feature | Chav Kawm II Cov Khoom Siv Uas Siv Tau Zoo | Chav Kawm III Cov Khoom Siv Uas Siv Tau Zoo |

Los ntawm kev siv cov txheej txheem tshwj xeebCov theem ntawm lub zog elastic ntawm orthodontic, koj tus kws kho mob tuaj yeem hloov kho qhov vector ntawm kev txav mus los. Qhov kev meej no yog vim li cascov roj hmab kho hniavraug suav hais tias yog "lub cav" ntawm theem kev ua kom zoo hauv kev kho mob orthodontic.
Vim li cas kuv tus kws kho hniav Orthodontist siv cov Elastics sib txawv?
Yog tias koj tau saib koj lub hnab roj hmab, tej zaum koj yuav pom cov npe zoo li "Hma liab," "Lav muag," lossis "Dais," nrog rau kev ntsuas zoo li3/16 nti orthodontic elasticsCov no tsis yog qhov tsis raws cai; lawv sawv cev rau cov lus qhia tshwj xeeb uas xav tau rau ntau theem ntawm kev txav hniav.
Kev suav lej ntawm kev ntxhov siab
Lub zog uas ib txoj hlua khi ua yog qhov tshwm sim ntawm nws txoj kab uas hla thiab qhov tuab ntawm cov khoom siv (phab ntsa tuab).
- Txoj kab uas hla:Cov qhov loj feem ntau suav nrog 1/8", 3/16", 1/4", 5/16", thiab 3/8".
- Cov Qib Zog:Muab faib ua pawg sib zog (kwv yees li 2.5 oz), Nruab nrab (kwv yees li 4.5 oz), thiab Hnyav (kwv yees li 6.5 oz).
Piv txwv li, ib3/16 nti orthodontic elasticmuab kev nruj ntau dua li txoj hlua 5/16 nti thaum ncab ntawm ob qho tib si. Siv qhov loj me tsis raug tuaj yeem ua rau kev nce qib tsis zoo lossis siv zog ntau dhau uas ua rau cov hauv paus hniav puas tsuaj (cov hauv paus hniav puas).
Yuav ua li cas yog tias kuv tsis nco qab hnav kuv cov Orthodontic Elastics rau ib hnub?
Kev sib xws yog qhov tseem ceeb tshaj plaws hauv kev sib raug zoolub sijhawm hnav elastic rau cov bracesKev txav mus los ntawm kev kho hniav yuav tsum tau "nias lub teeb tas li." Thaum koj tshem koj cov roj hmab, cov hniav pib "rov qab" lossis rov qab mus rau lawv qhov chaw qub yuav luag tam sim ntawd.
Txoj Cai "Ib Hnub So, Ob Hnub Rov Qab"
Hauv zej zog orthodontic, nws feem ntau hais tias rau txhua hnub koj nco hnav koj licov roj hmab orthodontic, nws yuav siv sijhawm ob hnub ntawm kev hnav tas li kom rov qab tau qhov av uas ploj lawm.
- Kev Ncua Sij Hawm Txog Kab Mob:Cov hlwb kho pob txha (osteoclasts thiab osteoblasts) siv sijhawm los ua haujlwm.
- Kev Kho Mob Tsis Tu Ncua:Kev hnav tsis sib xws ua rau cov hniav "jiggling," uas ua rau cov pob txha tsis ruaj khov.
- Lub Sijhawm Ntev:Cov neeg mob uas tsis ua raws li qhov tau teev tseg 22+ teev ntawm kev hnav feem ntau pom lawv lub sijhawm kho mob ntev dua 6 txog 12 lub hlis.
Kuv puas siv tau ob npaug rau cov Elastics kom txav kuv cov hniav sai dua?
Cov neeg mob feem ntau yuam kev tias hnav ob txoj hlua es tsis yog ib txoj yuav "ua kom sai dua". Qhov no tsis yog lus dag xwb tab sis kuj txaus ntshai thiab.
Vim li cas kev ua ob npaug thiaj li muaj teeb meem:
- Lub zog ntau dhau:Kev muab cov hlua khi ob npaug ua rau muaj lub zog "hnyav" uas cov leeg nqaij periodontal tsis tuaj yeem ua haujlwm.
- Kev Txwv Kev Ntws Ntshav:Yog muaj kev nyem ntau dhau ces yuav txiav tsis tau cov ntshav mus rau cov qauv txhawb nqa ntawm cov hniav.
- Kev puas tsuaj rau cov hauv paus hniav:Nws tuaj yeem ua rau cov hauv paus hniav luv dua (resorption), uas ua rau cov hniav tsis muaj zog mus tas li.
- Kev Txav Tsis Xav Tau:Lub zog ntau dhau tuaj yeem rub cov hniav mus rau hauv qhov chaw uas tus kws kho hniav tsis xav kom ua, ua rau muaj teeb meem tom hniav tshiab.
Ib txwm ua raws li qhov tshwj xeebCov theem ntawm lub zog elastic ntawm orthodonticuas koj tus kws tshaj lij tau sau tseg.
Cov Kev Xyaum Zoo Tshaj Plaws rau Kev Siv Cov Khoom Siv Kho Hniav Kom Raug
Kev siv kom raug yog qhov tseem ceeb rau kev txo qisqhov mob los ntawm cov hlua khi orthodonticthiab xyuas kom meej tias muaj txiaj ntsig zoo tshaj plaws. Ua raws li cov kauj ruam no kom tau txiaj ntsig zoo tshaj plaws:
