Nkhaniyi ndi malangizo okonzekera muyezo wa diaphragm womwe umagwiritsidwa ntchito kwa Aligners.Mukatha kuwerenga, mutha kumvetsetsa mafunso otsatirawa: Kodi mfundo ya orthodontics yosaoneka ndi yotani?Kodi ubwino wa orthodontics wosaoneka ndi wotani?Ndi kuchuluka kwa zingwe zomangira zosaoneka pa wodwala aliyense?Zomwe zimapangidwa ndi zinthuzomangira zosaoneka?

1. Chiyambi
Pochiza mano, mphamvu iliyonse yogwiritsidwa ntchito pa mano kuti asunthe, mosakayikira idzatulutsa mphamvu yosiyana ndi kukula kwake panthawi imodzi.Ntchito ya orthodontic appliance ndikupereka mphamvu iyi.Kuphatikiza pamankhwala ochiritsira opunduka a mano ndi waya wa orthodontic ndi mabatani a orthodontic, m'zaka zaposachedwa, chifukwa cha kusintha kwa zofunikira za odwala kukongola ndi chitonthozo, zida zamagetsi zopanda bulaketi zidayamba kugwiritsidwa ntchito kwambiri kuchipatala.Njira yochizira iyi ndikugwiritsa ntchito nembanemba ya thermoplastic kupanga chida chamunthu payekha.Chifukwa chakuti chipangizochi nthawi zambiri sichikhala ndi mtundu komanso chimaonekera, chimakwaniritsa zofunikira za tsiku ndi tsiku za wodwalayo.Komanso, chida chamtundu uwu chikhoza kuchotsedwa ndi kuvala ndi odwala okha, zomwe zimakhala zosavuta kuti odwala akwaniritse zosowa za kuyeretsa mano ndi kukongola kusiyana ndi zipangizo zamakono, choncho amalandiridwa ndi odwala ndi madokotala.
Chida chopanda bulaketi ndi chipangizo chapulasitiki chowonekera chopangidwa ndikupangidwa ndi makompyuta kuti chiwongolere mano.Zimakwaniritsa cholinga cha kayendedwe ka dzino mwa kusuntha mano mosalekeza pang'ono.Nthawi zambiri, ndi mtundu wa zingwe zowonekera zomwe zimagwiritsidwa ntchito kukonza mano.Mukasuntha dzino lililonse, sinthani chida china mpaka dzino lisunthike pomwe limafunikira komanso ngodya.Choncho, wodwala aliyense angafunike 20-30 awiriawiri a zipangizo pambuyo njira ya mankhwala 2-3 zaka.Ndi chitukuko ndi kupititsa patsogolo teknolojiyi m'zaka zapitazi za 20, milandu yambiri yosavuta yomwe imatha kumalizidwa ndi teknoloji yokhazikika ya orthodontic (zitsulo zachitsulo) zimatha kumalizidwa ndi mabulaketi opanda teknoloji ya orthodontic.Pakali pano, luso lopanda bulaketi limagwiritsidwa ntchito makamaka pakupunduka kwa dzino pang'onopang'ono, monga kudzaza dzino mpaka kalekale, danga la mano, odwala omwe amakonda kudwala, odwala omwe amabwereranso pambuyo pa chithandizo cha orthodontic, odwala omwe ali ndi ziwengo zitsulo, kusuntha kwa dzino, kuphatikizika kwapatsogolo. , etc. Zokhudzana ndi mano achitsulo
Setiyi imagwiritsa ntchito waya wa arch ndi bracket kukonza mano.Ukadaulo wa orthodontic wopanda bulaketi umawongolera mano kudzera pazida zowonekera, zodzichotsa zokha komanso zosawoneka bwino zopanda bulaketi.Choncho, palibe chifukwa cha zipangizo zamakono za orthodontic kuti zigwiritse ntchito waya wachitsulo wachitsulo wokhazikika pa mano popanda zingwe za mphete ndi mabatani, zomwe zimakhala zomasuka komanso zokongola.Chida chopanda bulaketi sichikuwoneka bwino.Chifukwa chake, anthu ena amachitcha chida chosawoneka.
Pakali pano, zida za orthodontic zopanda bulaketi nthawi zambiri zimapangidwa ndi nembanemba ya thermoplastic panjira yapakamwa ya wodwala potenthetsa ndi kukanikiza.Thermoplastic polima amagwiritsidwa ntchito ngati diaphragm.Amagwiritsa ntchito kwambiri copolyesters, polyurethane ndi polypropylene.Enieni omwe amagwiritsidwa ntchito kwambiri ndi: thermoplastic polyurethane (TPU), mowa-modified polyethylene terephthalate (PETG): zambiri polyethylene terephthalate 1,4-cyclohexanedimethanol ester, polyethylene terephthalate (PET), polypropylene (PP), polycarbonate (PC).PETG ndiye filimu yodziwika bwino kwambiri pamsika ndipo ndiyosavuta kupeza.Komabe, chifukwa cha njira zosiyanasiyana akamaumba
Kuchita kwa diaphragm kuchokera kwa opanga kumasiyananso.Thermoplastic polyurethane (TPU) ndi chinthu chotentha kwambiri pakugwiritsa ntchito kuwongolera mwachinsinsi m'zaka zaposachedwa, ndipo zinthu zabwino kwambiri zakuthupi zitha kupezeka kudzera mumitundu ina.The zipangizo paokha opangidwa ndi wosaoneka kudzudzulidwa kampani makamaka zochokera thermoplastic TPU ndi kusinthidwa ndi PET/PETG/PC ndi zikuphatikiza zina.Chifukwa chake, magwiridwe antchito a diaphragm pazida za orthodontic ndizofunikira kwambiri pakugwiritsa ntchito chida chopanda bracket.Popeza mtundu womwewo wa diaphragm ukhoza kukonzedwa ndikupangidwa ndi opanga osiyana orthodontic (makamaka mabizinesi opangira mano), ndipo zida zambiri zamakina opangidwa ndi orthodontic zimakhala zovuta kuwunika, ngati diaphragm yomwe imagwiritsidwa ntchito popanga chipangizo cha orthodontic sichinagwire ntchito komanso kuunika kwachitetezo, kungayambitse vuto lomwe wopanga zida za orthodontic aliyense amafunikira kuwunika mozama komanso mobwerezabwereza kachipangizo ka orthodontic, makamaka kuwunika kwachitetezo.Chifukwa chake, kuti tipewe vuto lomwe opanga zida zamagetsi zosiyanasiyana amawunika mobwerezabwereza mawonekedwe, mankhwala ndi chilengedwe cha diaphragm yomweyo (zofanana ndi zida zomwe zimagwiritsidwa ntchito popanga mano, monga utomoni wa mano, ndi zina), ndikusunga zothandizira, ndikofunikira kuyimitsa magwiridwe antchito ndi kuwunika kwa diaphragm yomwe imagwiritsidwa ntchito pazida zama orthodontic ndikupangamiyezo.,

Malinga ndi kafukufukuyu, pali mitundu 6 yazinthu zokhala ndi chiphaso cha orthodontic diaphragm cholembera zida zachipatala, kuphatikiza 1 yanyumba ndi 5 yochokera kunja.Pali mabizinesi pafupifupi 100 omwe amapanga zida zamagetsi zopanda mabulaketi.
Zizindikiro zazikulu za kulephera kwachipatala kwa diaphragm kwa chipangizo cha orthodontic popanda bracket ndi: kuthyoka / kung'ambika, kumasula pambuyo pogwiritsira ntchito mphamvu ya orthodontic, zotsatira za chithandizo chamankhwala kapena nthawi yayitali ya chithandizo, etc. Komanso, odwala amamva kupweteka kapena kupweteka nthawi zina.
Chifukwa zotsatira za chithandizo cha orthodontic popanda m'mabulaketi sizingokhudzana ndi momwe diaphragm imagwiritsidwira ntchito, komanso zimakhudza kwambiri kulondola kwa dokotala akutenga malingaliro a pakamwa a wodwalayo kapena kusanthula mkhalidwe wapakamwa, kulondola kwa chitsanzo, mawonekedwe a dongosolo lamankhwala a dotolo pagawo lililonse, makamaka pa chipangizo chopangidwa ndi mapulogalamu apakompyuta, kulondola kwa chipangizocho, malo omwe amathandizira mphamvu, komanso kutsatira kwa wodwala ndi dokotala, Zotsatirazi sizingawonekere. mu diaphragm yomwe.Chifukwa chake, tidayesetsa kuwongolera mtundu wa diaphragm yomwe imagwiritsidwa ntchito pazida zama orthodontic, kuphatikiza magwiridwe antchito ndi chitetezo, ndikupanga zizindikiro 10 zogwirira ntchito kuphatikiza "mawonekedwe", "fungo", "kukula", "kuvala kukana", "kukhazikika kwamafuta" , "pH", "heavy metal content", "evaporation residue", "Shore hardness" ndi "mechanical properties".
