Yog vim li cas Orthodontic Brackets Corrode nyob rau hauv lub qhov ncauj
Qhov Ncauj Qhov Ncauj Ib puag ncig
Lub qhov ncauj nthuav tawm ib puag ncig hnyav rau orthodontic brackets. Cov qaub ncaug muaj ntau yam ions thiab cov proteins. Cov tshuaj no niaj hnub cuam tshuam nrog cov khoom siv bracket. Cov kub hloov pauv tshwm sim ntau zaus. Cov neeg mob haus cov zaub mov kub thiab txias thiab dej qab zib. Cov no hloov kev ntxhov siab rau cov hlau. Cov khoom noj thiab dej haus sib txawv kuj qhia txog cov kua qaub. Cov kua qaub no tuaj yeem ua rau lub ntsej muag bracket. Cov kab mob hauv lub qhov ncauj tsim biofilms. Cov biofilms no tsim cov kab mob acidic hauv zos. Tag nrho cov xwm txheej no ua ke los txhawb kev txhim kho corrosion.
Qhov tshwm sim ntawm Bracket Material Degradation
Bracket khoom degradation ua rau ntau yam teeb meem. Corroding brackets tso cov hlau ions rau hauv lub qhov ncauj. Cov ions no tuaj yeem ua rau muaj kev tsis haum rau qee tus neeg mob. Lawv kuj tuaj yeem cuam tshuam cov ntaub so ntswg ib puag ncig. Corrosion tsis muaj zog lub bracket qauv. Lub bracket tsis muaj zog tuaj yeem tawg lossis deform. Qhov no cuam tshuam txoj kev kho mob. Nws tuaj yeem ncua sijhawm kho. Corroded brackets kuj saib unsightly. Lawv tuaj yeem stain cov hniav lossis tshwm tsis muaj xim. Qhov no cuam tshuam rau tus neeg mob zoo nkauj thiab txaus siab.
Yuav ua li cas Fluoride cuam tshuam Corrosion
Fluoride plays lub luag haujlwm nyuaj hauv bracket corrosion. Cov kws kho hniav feem ntau pom zoo fluoride rau kev tiv thaiv kab noj hniav. Fluoride txhawb cov hniav enamel. Txawm li cas los xij, fluoride qee zaum tuaj yeem cuam tshuam cov khoom siv bracket. High concentrations ntawm fluoride yuav ua rau kom tus nqi corrosion ntawm tej alloys. Qhov no tshwm sim los ntawm cov tshuaj tiv thaiv tshwj xeeb. Cov kws tshawb fawb tshawb fawb txog cov kev sib cuam tshuam no kom zoo. Lawv tsom mus tsim cov ntaub ntawv uas tiv thaiv fluoride-induced corrosion. Qhov no ua kom ob qho tib si tiv thaiv hniav thiab bracket kev ncaj ncees.
Txhim khu kev ruaj ntseg nrog hlau-raws li txheej
Hlau-raws li txheej txheej muaj cov tshuaj muaj zog rau kev txhim kho orthodontic bracket durability. Cov txheej nyias no tiv thaiv cov khoom siv hauv qab. Lawv ua rau kom tsis txhob hnav thiab corrosion. Tshooj lus no tshawb txog qee cov txheej txheem hlau uas nrov.
Titanium Nitride (TiN) daim ntawv thov
Titanium Nitride (TiN) yog cov khoom siv tawv tawv heev. Nws feem ntau tshwm raws li nyias, kub-xim txheej. Cov neeg tsim khoom siv TiN rau ntau yam cuab yeej thiab khoom siv kho mob. Cov txheej no ua rau kom muaj zog ntawm qhov chaw. Nws kuj txhim kho kev hnav tsis kam. Rauorthodontic brackets, TiN tsim kev tiv thaiv kev tiv thaiv. Qhov kev thaiv no tiv thaiv cov hlau los ntawm cov ntsiab lus corrosive hauv lub qhov ncauj.
TiN coatings txo kev sib txhuam ntawm cov archwire thiab lub bracket qhov. Qhov no tuaj yeem pab cov hniav txav tau yooj yim dua. Cov neeg mob yuav muaj sij hawm kho mob luv dua.
TiN kuj qhia tau hais tias zoo biocompatibility. Qhov no txhais tau tias nws tsis ua mob rau cov ntaub so ntswg. Nws txo qis kev tsis haum tshuaj. Nws du nto resists kab mob adhesion. Qhov no yuav pab tswj kev huv ntawm qhov ncauj kom zoo nyob ib ncig ntawm lub bracket.
Zirconium Nitride (ZrN) rau kev tiv thaiv corrosion
Zirconium Nitride (ZrN) yog lwm qhov kev xaiv zoo tshaj plaws rau cov txheej txheem bracket. Nws qhia ntau yam txiaj ntsig nrog TiN. ZrN kuj muab siab hardness thiab hnav tsis kam. Nws cov xim feem ntau yog lub teeb daj lossis bronze. Cov txheej no muaj kev tiv thaiv corrosion zoo tshaj. Nws tsim ib txheej ruaj khov uas tiv taus acids thiab lwm yam tshuaj 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.
Pob zeb diamond zoo li Carbon (DLC) Cov txiaj ntsig
Pob zeb diamond zoo li Carbon (DLC) txheej yog tshwj xeeb. Lawv muaj cov khoom zoo ib yam li pob zeb diamond. Cov khoom no muaj xws li qhov nyuaj hardness thiab tsis tshua muaj kev sib txhuam. DLC txheej yog nyias heev. Lawv kuj zoo heev rau hnav thiab corrosion. Lawv cov tsos dub lossis grey tsaus tuaj yeem muab cov txiaj ntsig zoo nkauj.
DLC coatings tsim ib tug incredibly du nto. Qhov no smoothness txo kev sib txhuam ntawm lub bracket thiab archwire. Kev sib txhuam qis tso cai rau cov hniav txav tau zoo dua. Nws kuj tuaj yeem txo cov neeg mob tsis xis nyob. Tsis tas li ntawd, DLC coatings yog biocompatible heev. Lawv tsis ua rau muaj kev phiv hauv qhov ncauj. Lawv qhov xwm txheej tsis zoo tiv thaiv cov hlau ion tso tawm. Qhov no ua rau lawv xaiv zoo rau cov neeg mob uas muaj hlau rhiab heev. DLC kuj tiv thaiv kab mob colonization. Qhov no yuav pab kom lub bracket nto huv si.
Polymer Txheej rau Biocompatibility thiab Flexibility
Polymer txheej muaj qhov tshwj xeeb zoo rauorthodontic brackets.Lawv muab biocompatibility zoo heev. Lawv kuj muab tau yooj yim. Cov txheej txheem no tiv thaiv cov hlau hauv qab. Lawv kuj cuam tshuam zoo nrog cov ntaub so ntswg ntawm qhov ncauj.
Polytetrafluoroethylene (PTFE) hauv Orthodontics
Polytetrafluoroethylene (PTFE) yog ib tug paub zoo polymer. Ntau tus neeg paub tias nws yog Teflon. PTFE muaj cov khoom tshwj xeeb. Nws muaj qhov sib txhuam coefficient tsawg heev. Nws kuj yog chemically inert. Qhov no txhais tau tias nws tsis hnov mob nrog ntau yam tshuaj. PTFE yog biocompatible heev. Nws tsis ua rau muaj kev phiv tshwm sim hauv lub cev.
Cov neeg tsim khoom siv PTFE ua ib txheej nyias ntawm orthodontic brackets. Cov txheej no txo cov kev sib txhuam ntawm cov archwire thiab lub bracket slot. Kev sib txhuam qis tso cai rau cov hniav kom txav tau yooj yim dua. Qhov no tuaj yeem txo lub sijhawm kho. PTFE's non-stick nto kuj pab. Nws tiv thaiv plaque buildup. Nws kuj ua rau kev ntxuav yooj yim rau cov neeg mob. Cov txheej tiv thaiv cov khoom siv bracket los ntawm corrosion. Nws tsim ib qho kev tiv thaiv tiv thaiv acids thiab enzymes hauv lub qhov ncauj.
