Raws li cov cuab yeej tshwj xeeb tu rau lub qhov ncauj ib puag ncig thaum kho orthodontic, qhov kev xaiv ntawm cov khoom siv rau orthodontic floss picks ncaj qha cuam tshuam rau lawv txoj kev nyab xeeb, tu kom zoo, thiab kav ntev. Ib puag ncig uas lawv tau siv yog tus cwj pwm los ntawm cov av noo, qhov kub thiab txias, thiab rov sib txhuam, thiab qee cov txheej txheem xav tau kev sib cuag nrog lub qhov ncauj mucosa. Yog li ntawd, cov khoom siv yuav tsum tsis yog tsuas yog ua tau raws li cov txheej txheem kev siv tshuab thiab kev tu, tab sis kuj ua raws li cov kev qhia xws li biocompatibility, tshuaj lom neeg ruaj khov, thiab cov txheej txheem tsim nyog.
Cov ntsiab lus tseem ceeb ntawm kev siv cov hlua khi orthodontic suav nrog cov hlua khi nws tus kheej thiab tus kov, txhua tus nrog nws cov khoom siv thiab kev ua haujlwm tseem ceeb. Floss nws tus kheej feem ntau yog ua los ntawm siab- lub zog polymer fibers lossis cov fibers sib xyaw, xws li ultra- siab molecular hnyav polyethylene (UHMWPE), polyester (PET), thiab nylon. Cov ntaub ntawv no muaj lub zog tensile zoo heev thiab kev puas tsuaj, tso cai rau lawv rov qab los ntawm qhov khoob ntawm archwires thiab brackets yam tsis yooj yim tawg lossis fraying. Qee cov khoom lag luam muaj cov micro-textured lossis qis- cov coatings kev sib txhuam ntawm cov ntaub nplaum los txhim kho nws cov cuab yeej cuab yeej tshem tawm cov quav hniav thiab txo cov kev mus los. Kev xaiv cov khoom yuav tsum sib npaug hardness thiab yooj; hardness ntau dhau tuaj yeem ua rau cov pos hniav los yog cov khoom siv orthodontic, thaum cov softness ntau dhau ua rau lub zog tu tsis txaus thiab deformation yooj yim.
Tus kov yog lub luag haujlwm rau kev tuav thiab tswj, yuav tsum muaj qhov sib npaug ntawm cov khoom tiv thaiv- plam, dej tsis kam, thiab xis nyob. Cov khoom siv feem ntau suav nrog cov yas engineering xws li acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), thiab thermoplastic elastomers (TPE). ABS thiab PC muab cov qauv zoo thiab qhov ruaj khov, haum rau ib qho -daim molding ntawm txoj kev tuav cov duab; TPE muab qhov muag kov thiab tiv thaiv- cov khoom plam, tuav ruaj khov txawm tias nyob hauv qhov chaw ntub dej. Cov khoom siv tes yuav tsum muaj peev xwm tiv taus cov tshuaj tua kab mob thiab tshuaj tua kab mob, tiv thaiv kev laus, tawg, lossis nto tev vim tshuaj lom neeg corrosion.
Biosafety yog ib qho tseem ceeb hauv kev xaiv cov khoom siv tshuaj txhuam hniav. Vim hais tias cov suture yuav luv luv los rau hauv kev sib cuag nrog cov pos hniav, buccal mucosa, thiab lwm yam, thaum lub sij hawm tus txheej txheem, thiab tus kov yuav kis tau los ntawm txhais tes hws los yog qaub ncaug, cov ntaub ntawv xaiv yuav tsum tau raws li kev kho mob los yog zaub mov tiv tauj cov qauv thiab xeem dhau cov kev ntsuam xyuas xws li cytotoxicity, daim tawv nqaij khaus, thiab rhiab heev kom tsis txhob muaj teeb meem Cheebtsam migrate. Rau cov khoom uas yuav tsum tau siab -kub sterilization, cov khoom yuav tsum kuj muaj cua sov ua hauj lwm zoo thiab muaj kev ruaj ntseg kev ua tau zoo nyob rau hauv rov qab chav los yog ultraviolet hluav taws xob.
Tshuaj compatibility kuj muaj feem xyuam rau cov khoom lifespan thiab ntxuav cov hauj lwm zoo. Orthodontic ib puag ncig feem ntau siv nruab nrab lossis tsis muaj zog alkaline ntxuav kev daws teeb meem thiab cov tshuaj fluoride lub qhov ncauj rau kev pab tu; tus kov thiab cov ntaub ntawv suture yuav tsum tiv thaiv cov teebmeem corrosive ntawm cov xov xwm no, tsis muaj o, fading, lossis kev ua haujlwm tsis zoo. Rau cov xwm txheej tshwj xeeb uas sib cuag nrog cov quav hniav orthodontic, resin adhesives, thiab lwm yam, cov khoom siv los tiv thaiv - adhesion thiab yooj yim- rau - cov khoom huv si yuav tsum tau soj ntsuam kom txo tau cov kab mob seem.
Txheej txheem compatibility yog ib qho kev txiav txim siab txuas ntxiv hauv kev xaiv cov khoom. Yog hais tias lub suture muaj ib tug braided los yog multi-strand twisted qauv, nws yog tsim nyog los xyuas kom meej muaj zog bonds ntawm fibers thiab ruaj khov kub; Yog hais tias tus kov siv ob - xim txhaj tshuaj molding los yog overmolding txheej txheem, nws yog ib qho tsim nyog los xyuas kom meej kev sib raug zoo ntawm cov khoom sib txawv thiab tsis muaj kev pheej hmoo ntawm tev. Kev xaiv cov khoom yuav tsum tau koom tes nrog cov txheej txheem molding kom tsis txhob muaj qhov tsis xws luag los ntawm kev tsis sib haum xeeb hauv cov ntsiab lus melting, shrinkage tus nqi, los yog cov khoom sib txuas.
Feem ntau, kev xaiv cov ntaub ntawv rau orthodontic floss picks yuav tsum tau coj los ntawm daim ntawv thov ib puag ncig, kev ntsuam xyuas txhua yam muaj zog, yoog raws, biocompatibility, tshuaj lom neeg ruaj khov, thiab cov txheej txheem tsim nyog. Kev xaiv cov khoom tsim nyog thiab tsim nyog tsis yog tsuas yog txhim kho kev ua haujlwm huv thiab kev nplij siab ntawm cov neeg siv xwb tab sis kuj tseem txuas ntxiv lub neej kev pabcuam thiab ua kom cov neeg mob muaj kev nyab xeeb, muab cov khoom siv txhim khu kev qha rau kev saib xyuas qhov ncauj orthodontic thiab tso lub hauv paus rau kev tsim qauv thiab txhim kho cov khoom muaj feem xyuam.
