Waya wa orthodontic arch

Pa chithandizo cha mano, waya wa orthodontic arch ndi chimodzi mwa zigawo zazikulu za zida zokhazikika za orthodontic, zomwe zimatsogolera kuyenda kwa mano pogwiritsa ntchito mphamvu yokhazikika komanso yowongoka. Izi ndi chiyambi chatsatanetsatane chokhudza mawaya a orthodontic:

1: Udindo wa mawaya odulira mano Kutumiza mphamvu yodulira mano:

Kugwiritsa ntchito mphamvu pa mano kudzera mu kusintha kwa elasticity kuti mukwaniritse zolinga monga kulinganiza, kulinganiza, ndi kutseka mipata. Kusunga mawonekedwe a arch ya mano: Kapangidwe ka mawonekedwe a arch komwe kamathandizira kukonzedwa kwa mano, kusunga m'lifupi ndi kutalika kwa arch ya mano. Kutsogolera kayendedwe ka 3D: Mogwirizana ndi kapangidwe ka bracket, lamulirani lilime la milomo, kuyima, ndi kuzungulira kwa mano.

2: Kugawa waya wa arch

2.1. Gawani malinga ndi zinthu zomwe zilipo Makhalidwe a mtundu wa zinthu, magawo ogwiritsidwa ntchito nthawi zambiri

Waya wa aloyi wa nickel titanium: wotanuka kwambiri, wokumbukira mawonekedwe, mphamvu yofatsa komanso yopitilira, yoyenera kulinganiza koyamba.

Waya wosapanga dzimbiri: wolimba kwambiri komanso wolimba, womwe umagwiritsidwa 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:

Kawirikawiri mainchesi 0.012-0.020 m'mimba mwake, poyamba ali ofanana ndi waya wozungulira: monga mainchesi 0.016 × 0.022, mainchesi 0.021 × 0.025, zomwe zimathandiza kuti pakhale mphamvu yolamulira mphamvu.

Ulusi wolukidwa: Ulusi wopyapyala wopangidwa ndi zingwe zingapo kuti akonze mano olakwika kwambiri.

2.3. Waya wapadera wa mano ozungulira waya:

chopindika kale, chomwe chimagwiritsidwa ntchito pokonza chophimba chakuya kapena kutsegula ndi kutseka.

3: Kugwirizana ndi machitidwe ena a orthodontic. Mabulaketi achikhalidwe:

dalirani pa kukhazikika kwa ligation, ndipo mulingo wofanana pakati pa waya wa archwire ndi bracket groove uyenera kuganiziridwa.

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

Kusankhidwa kwa mawaya a orthodontic kumakhudza mwachindunji zotsatira za chithandizo ndi zomwe wodwala akukumana nazo, ndipo kumafuna kapangidwe kathunthu kutengera mtundu wa malocclusion, gawo la orthodontic, ndi dongosolo la bracket. Ndipo tili ndi zinthu zonse zomwe zatchulidwa pamwambapa zomwe zimagwirizana ndi chithandizo. Ngati pakufunika, mutha kupita patsamba lathu lovomerezeka kudzera patsamba loyamba kuti muwone zinthu zomwe zimakusangalatsani.
