Orthodontic arch hlau

Hauv kev kho hniav orthodontic, orthodontic arch wire yog ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv kho hniav ruaj khov, uas coj cov hniav txav los ntawm kev siv lub zog ruaj khov thiab tswj tau. Hauv qab no yog cov lus qhia ntxaws ntxaws txog cov hlau orthodontic:

1: Lub luag hauj lwm ntawm orthodontic wires Transmitting orthodontic force:

Siv dag zog rau cov hniav los ntawm elastic deformation kom ua tiav cov hom phiaj xws li kev sib tw, qib, thiab kaw qhov sib txawv. Kev tuav cov hniav arch zoo li: Lub arc-zoo li tus qauv uas txhawb cov kev npaj ntawm cov hniav, tswj qhov dav thiab ntev ntawm cov hniav arch. Kev taw qhia 3D txav: Ua ke nrog kev tsim qauv bracket, tswj lub di ncauj tus nplaig, ntsug, thiab kev sib hloov ntawm cov hniav.

2: Classification ntawm arch hlau

2.1. Muab faib los ntawm cov khoom siv Cov yam ntxwv ntawm cov khoom siv, cov txheej txheem kev siv

Nickel titanium alloy hlau: super elastic, zoo lub cim xeeb nyhuv, maj mam thiab nruam quab yuam, haum rau thawj zaug sib dhos.

Stainless hlau xaim: siab hardness thiab rigidity, siv rau kev tswj kom meej ntawm cov hniav txoj hauj lwm.

TMA: Lub elastic modulus yog nruab nrab ntawm nickel titanium thiab stainless hlau, thiab nws tuaj yeem khoov nrog lub zog me me, haum rau nruab nrab lub sijhawm hloov.

2.2. Faib raws li cov duab ntawm qhov seem. Hlau voj voog:

Feem ntau 0.012-0.020 ntiv tes nyob rau hauv txoj kab uas hla, pib dlhos Rectangular hlau: xws li 0.016 × 0.022 ntiv tes, 0.021 × 0.025 ntiv tes, muab torque tswj.

Braided xov: Ntau cov xov ntawm cov xov zoo woven rau thawj zaug kho cov hniav tsis zoo.

2.3. Tshwj xeeb muaj nuj nqi kho hniav arch hlau Rov qab nkhaus hlau:

ua ntej nkhaus, siv rau kev kho ntsug ntawm kev npog tob lossis qhib thiab kaw.

3: Kev koom tes nrog lwm cov kab ke orthodontic Cov kab ke ib txwm:

cia siab rau ligation fixation, thiab qhov sib txuam degree ntawm archwire thiab bracket zawj yuav tsum tau xav txog.

Self ligating bracket: txo ligation kev sib txhuam thiab ua kom yooj yim rau swb.

Kev xaiv ntawm cov xov hlau orthodontic ncaj qha cuam tshuam rau cov txiaj ntsig kev kho mob thiab cov neeg mob kev paub dhau los, thiab yuav tsum muaj kev tsim qauv zoo raws li hom malocclusion, orthodontic theem, thiab bracket system.Thiab peb muaj tag nrho cov khoom uas tau hais los saum toj no uas haum rau kev kho mob. Yog tias xav tau, koj tuaj yeem mus saib peb lub vev xaib official los ntawm lub vev xaib los saib cov khoom uas koj nyiam.
