Zotsatirazi ndizofotokozera mwatsatanetsatane za mawaya a orthodontic:

1: Udindo wa mawaya a orthodontic Kutumiza mphamvu ya orthodontic:

Kugwiritsa ntchito mphamvu m'mano kudzera m'mapindika otanuka kuti mukwaniritse zolinga monga kuyanjanitsa, kusanja, ndi kutseka mipata. Kusunga mawonekedwe a arch a mano: Kapangidwe kamene kamakhala ngati arc komwe kamathandizira dongosolo la mano, kusungitsa m'lifupi ndi kutalika kwa khosi la mano. Kuwongolera mayendedwe a 3D: Molumikizana ndi mapangidwe a bulaketi, wongolera lilime la milomo, kuima, ndi kuzungulira kwa mano.

2: Gulu la waya wa arch

2.1. Sankhani motengera zinthu zamtundu wa zinthu, magawo omwe amagwiritsidwa ntchito nthawi zambiri

Waya wa Nickel titanium alloy: wapamwamba zotanuka, mawonekedwe amakumbukidwe, mphamvu yofatsa komanso yopitilira, yoyenera kuyanjanitsa koyambirira.

Waya wachitsulo chosapanga dzimbiri: kuuma kwakukulu komanso kulimba, komwe kumagwiritsidwa ntchito powongolera bwino malo a dzino.

TMA: Modulus yosalala ili pakati pa nickel titanium ndi chitsulo chosapanga dzimbiri, ndipo imatha kupindika ndi mphamvu yofatsa, yoyenera kusinthidwa pakati pa nthawi.

2.2. Gawani mawonekedwe ake pogwiritsa ntchito waya wozungulira:

nthawi zambiri mainchesi 0.012-0.020 m'mimba mwake, poyambira amalumikizana ndi waya wamakona anayi: monga mainchesi 0.016 × 0.022 mainchesi, 0.021 × 0.025 mainchesi, kupereka mphamvu zowongolera makokedwe.

Ulusi wolukidwa: Ulusi wambiri wolukidwa kuti uwongolere mano osokonekera kwambiri.

2.3. Waya wapadera wamano arch wire Reverse curve waya:

chopindika, chomwe chimagwiritsidwa ntchito posintha moyima chophimba chakuya kapena kutsegula ndi kutseka.

3:Kugwirizana ndi machitidwe ena a orthodontic Mabulaketi Achikhalidwe:

kudalira kukhazikika kwa ligation, ndipo digiri yofananira pakati pa archwire ndi poyambira bracket iyenera kuganiziridwa.

Chitseko chodzimanga: chimachepetsa kukangana kwa chitseko ndipo chimapangitsa kuti chikhale chosavuta kutsetsereka.

Kusankhidwa kwa mawaya a orthodontic kumakhudza mwachindunji zotsatira za chithandizo ndi zochitika za odwala, ndipo zimafuna mapangidwe athunthu okhudzana ndi mtundu wa malocclusion, orthodontic stage, ndi bracket system.Ndipo tili ndi zinthu zonse zomwe tazitchula pamwambapa zomwe zimagwirizana ndi chithandizo. Ngati pakufunika, mutha kupita patsamba lathu lovomerezeka kudzera patsamba lofikira kuti muwone zomwe zimakusangalatsani.
