Tsis tsuas yog tuaj yeem muaj cov ntxhiab tsw ntxhiab hauv koj cov hniav, tab sis nws kuj tuaj yeem ua rau muaj ntau yam teeb meem ntawm qhov ncauj xws li hniav rhiab heev.Ib qho txhuam hniav interdental, tseem hu ua txhuam hniav interdental, zoo ib yam hauv kev tsim kho rau cov txhuam hniav tsis tu ncua, muaj ob ntu: txhuam taub hau thiab txhuam txhuam.Txawm li cas los xij, qhov sib txawv loj tshaj plaws piv rau cov txhuam hniav ib txwm yog qhov tsim ntawm txhuam taub hau, uas yog lub khob hliav qab thiab muaj nyob rau hauv ntau qhov sib txawv rau qhov dav ntawm cov hniav.

Feem ntau ntawm cov txhuam hniav filaments ntawm lub khw siv nylon thiab PBT filaments.Cov khoom siv raw rau txhuam hniav nylon filaments feem ntau yog xaiv los ntawm nylon 610 thiab nylon 612, uas muaj qhov nqus dej tsawg thiab tuaj yeem tswj tau qhov kev ua tau zoo hauv chav dej ntub dej.Tsis tas li ntawd, nylon 610 thiab nylon 612 kuj tseem muaj kev hnav zoo heev thiab khoov rov qab, tshwj xeeb tshaj yog rau cov txhuam hniav hluav taws xob ntawm cov khoom siv txhuam hniav, ib qho filament rov qab yog siab dua 60%, 610 thiab 612 nylon filaments qhia zoo dua rigidity thiab tsis kam. rov qab cov plaub hau kev ua tau zoo, zoo resilience, toughness, tuaj yeem nkag mus tob rau hauv qhov sib txawv ntawm cov hniav, ua kom pom tseeb cov plaque thiab cov khoom noj seem, kev tu kom zoo.Kev tu kom zoo dua qub thiab cov txhuam hniav uas tsim muaj lub neej ntev dua.
