Vim li cas Orthodontic Brackets thiaj xeb hauv qhov ncauj
Ib puag ncig qhov ncauj uas nruj heev
Lub qhov ncauj muaj ib puag ncig nyuaj rau cov hniav orthodontic. Cov qaub ncaug muaj ntau yam ions thiab protein. Cov tshuaj no sib cuam tshuam tas li nrog cov khoom siv bracket. Kev hloov pauv kub tshwm sim ntau zaus. Cov neeg mob noj cov khoom noj kub thiab txias thiab dej haus. Cov kev hloov pauv no ua rau cov hlau ntxhov siab. Cov khoom noj thiab dej haus sib txawv kuj ua rau muaj cov kua qaub. Cov kua qaub no tuaj yeem tawm tsam qhov chaw ntawm bracket. Cov kab mob hauv lub qhov ncauj tsim cov biofilms. Cov biofilms no tsim cov xwm txheej acidic hauv zos. Tag nrho cov yam no ua ke los txhawb kev xeb.
Cov txiaj ntsig ntawm kev puas tsuaj ntawm cov khoom siv bracket
Kev puas tsuaj ntawm cov khoom siv bracket ua rau muaj ntau yam teeb meem. Cov hlau kho hniav uas xeb yuav tso cov hlau ions rau hauv qhov ncauj. Cov hlau ions no tuaj yeem ua rau muaj kev tsis haum tshuaj rau qee tus neeg mob. Lawv kuj tseem yuav cuam tshuam rau cov ntaub so ntswg nyob ib puag ncig. Kev xeb ua rau lub qauv hlau kho hniav tsis muaj zog. Lub hlau kho hniav uas tsis muaj zog tuaj yeem tawg lossis puas. Qhov no ua rau kev kho mob tsis zoo. Nws tuaj yeem ncua sijhawm kho mob. Cov hlau kho hniav uas xeb kuj zoo li tsis zoo nkauj. Lawv tuaj yeem ua rau cov hniav puas lossis zoo li tsis muaj xim. Qhov no cuam tshuam rau tus neeg mob qhov zoo nkauj thiab kev txaus siab.
Fluoride Cuam Tshuam Li Cas Rau Kev Xeb
Fluoride ua lub luag haujlwm tseem ceeb hauv kev xeb ntawm lub bracket. Cov kws kho hniav feem ntau pom zoo kom siv fluoride los tiv thaiv qhov lwj. Fluoride ua rau cov hniav enamel muaj zog. Txawm li cas los xij, qee zaum fluoride tuaj yeem cuam tshuam rau cov khoom siv bracket. Cov tshuaj fluoride ntau dhau yuav ua rau cov hlau alloys xeb ntau dua. Qhov no tshwm sim los ntawm cov tshuaj lom neeg tshwj xeeb. Cov kws tshawb fawb kawm txog cov kev sib cuam tshuam no kom zoo zoo. Lawv lub hom phiaj yog tsim cov khoom siv uas tiv taus kev xeb los ntawm fluoride. Qhov no ua kom ntseeg tau tias ob qho tib si kev tiv thaiv cov hniav thiab kev ruaj khov ntawm lub bracket.
Txhim Kho Kev Ruaj Ntseg Nrog Cov Txheej Txheem Hlau
Cov txheej hlau ua rau muaj kev daws teeb meem zoo rau kev txhim kho qhov ruaj khov ntawm lub bracket orthodontic. Cov txheej nyias no tiv thaiv cov khoom siv hauv qab ntawm lub bracket. Lawv ua rau muaj kev tiv thaiv kev hnav thiab xeb. Ntu no tshawb nrhiav qee cov txheej hlau nrov.
Cov Kev Siv Titanium Nitride (TiN)
Titanium Nitride (TiN) yog ib yam khoom siv ceramic uas tawv heev. Nws feem ntau zoo li ib txheej nyias nyias, xim kub. Cov chaw tsim khoom siv TiN rau ntau yam cuab yeej thiab cov khoom siv kho mob. Cov txheej no ua rau qhov chaw tawv dua. Nws kuj tseem txhim kho kev tiv thaiv kev hnav. Raucov hlau kho hniav, TiN tsim ib daim thaiv kev tiv thaiv. Daim thaiv no tiv thaiv cov hlau ntawm cov khoom corrosive hauv qhov ncauj.
Cov txheej TiN txo qhov kev sib txhuam ntawm cov hlau archwire thiab qhov bracket. Qhov no tuaj yeem pab cov hniav txav tau zoo dua. Cov neeg mob yuav muaj lub sijhawm kho mob luv dua.
TiN kuj qhia tau tias nws sib haum zoo. Qhov no txhais tau tias nws tsis ua rau cov nqaij mos muaj sia puas tsuaj. Nws txo qhov kev ua xua. Nws qhov chaw du thiab tiv taus cov kab mob sib txuas. Qhov no pab tswj kev huv ntawm qhov ncauj zoo dua nyob ib puag ncig lub bracket.
Zirconium Nitride (ZrN) rau Kev Tiv Thaiv Kev Sib Tsoo
Zirconium Nitride (ZrN) yog lwm txoj kev xaiv zoo heev rau cov txheej txheem bracket. Nws muaj ntau yam zoo ib yam li TiN. ZrN kuj muaj qhov nyuaj thiab tiv taus kev hnav. Nws cov xim feem ntau yog daj daj lossis tooj liab. Cov txheej txheem no muaj kev tiv thaiv kev xeb zoo heev. Nws tsim ib txheej ruaj khov uas tiv taus cov kua qaub thiab lwm yam tshuaj lom neeg hnyav.
Cov kws tshawb nrhiav pom tias ZrN muaj txiaj ntsig zoo rau qhov chaw hauv qhov ncauj. Nws tiv taus kev raug cov qaub ncaug thiab cov kua qaub hauv zaub mov tas li. Qhov no tiv thaiv kev tso tawm cov hlau ions los ntawm lub bracket. Kev tso tawm ion tsawg dua txhais tau tias muaj kev tsis haum tshuaj tsawg dua. Nws kuj tseem tswj tau qhov kev ua haujlwm ntawm lub bracket dhau sijhawm. Cov txheej txheem ZrN pab txhawb rau kev kho hniav kom ruaj khov thiab txhim khu kev qha dua.
Cov txiaj ntsig ntawm Cov Pa roj carbon zoo li pob zeb diamond (DLC)
Cov txheej txheej uas zoo li pob zeb diamond (DLC) yog cov tshwj xeeb. Lawv muaj cov yam ntxwv zoo ib yam li pob zeb diamond ntuj. Cov yam ntxwv no suav nrog kev tawv heev thiab kev sib txhuam tsawg. Cov txheej txheej DLC yog nyias heev. Lawv kuj tiv taus kev hnav thiab xeb heev. Lawv cov tsos dub lossis grey tsaus kuj tseem tuaj yeem muab qhov zoo nkauj.
