Kev siv niobium hauv orthodontics

Hlau orthodontic archwires muaj lawv cov cuab yeej cuab tam yooj yim, xws li kev ua kom txaus, tsis muaj zog, zoo formability, thiab zoo biocompatibility thiab ib puag ncig stability. Feem ntau siv cov ntaub ntawv rau hlau orthodontic archwires yog stainless hlau, drilled chromium alloys, nickel-titanium alloys, thiab titanium-molybdenum alloys. Kev siv niobium hauv orthodontic hneev xov hlau tsis tshua muaj ntaub ntawv zoo, thiab nws tau pom tias niobium feem ntau yog siv los ua ib feem ntawm B-titanium alloy hneev hlau txhawm rau txhawm rau txhim kho cov khoom siv hluav taws xob ntawm hneev xov hlau thiab txo cov modulus ntawm elasticity. Niobium-muaj titanium alloy hneev xov hlau muaj qhov sib npaug ntawm cov khoom siv zoo, xws li kev ua haujlwm nruab nrab, sib npaug nruj, zoo formability, thiab muaj peev xwm yuav welded rau attachments.Suzuki li al. piv rau qhov sib txawv ntawm cov khoom sib txawv ntawm Ti-Nb-Al alloy hneev nti thiab cov pa Ni-Ti alloy hneev nti, thiab pom tau tias thawj zaug resilience ntawm Ti-Nb-Al alloy hneev nti yog ib nrab ntawm Ni-Ti alloy hneev hlau. , uas qhia tau hais tias thawj zaug resilience ntawm alloy hneev hlau yog tsuas yog ib nrab ntawm cov hlau hneev nti, thiab qhov no yog qhov sib txawv tseem ceeb hauv cov khoom siv kho tshuab. Cov txiaj ntsig tau pom tias thawj zaug rov qab quab yuam ntawm Ti-Nb-Al alloy hneev taw tsuas yog ib nrab ntawm Ni-Ti alloy hneev hlau, uas qhia tau hais tias yav dhau los tuaj yeem siv zog ntau dua thiab ruaj khov. Tsis tas li ntawd, Ti-Nb-Al alloy cov xov hlau tau pom tias ua rau cov hniav sib luag thiab txuas ntxiv mus, thiab Kuroda li al. tau pom tias Ti-Nb-Al alloy xov hlau yog tsawg dua torquey tshaj titanium-molybdenum alloy thiab cov pa Ni-Ti hlau hlau.

Nrog rau kev txhim kho txuas ntxiv ntawm cov ntaub ntawv tshawb fawb, cov ntaub ntawv siv rau orthodontic archwires tau hloov kho tas li, thiab ntau cov ntaub ntawv tsis yog xim hlau rau archwires tau tsim thiab siv hauv tsev kho mob. Clinically, cov ntaub ntawv sib txawv thiab cov qauv ntawm archwires yuav tsum raug xaiv raws li hom kev kho hniav tsis zoo thiab cov phiaj xwm kev kho hniav ntawm tus kheej.
