Kapangidwe ndi ntchito wamba

Ma ligature a elastomeric amapangidwa ngati mphete za O zomwe zili ndi mbali imodzi, zosiyana. Nthawi zambiri zimakhala ndi mainchesi akunja kuyambira 0.110 mpaka 0.120, mainchesi amkati pafupifupi 0.040 mpaka 0.050, ndi makulidwe a mainchesi 0.030 mpaka 0.035. Ntchito yawo yayikulu ndikulumikiza mapiko anayi omangira a bracket yokhazikika, ndikugwirizira waya wa arch pamalo ake. Nthawi zambiri amaperekedwa pamitengo yowumbidwa kapena ndodo, yokhala ndi ma module 10 mpaka 24 iliyonse, zomwe zimathandiza kugwiritsa ntchito mwachangu pogwiritsa ntchito hemostat kapena director wapadera wa ligature.

Koma maunyolo amphamvu, kumbali ina, amakhala ndi mzere wopitilira wa ma module olumikizidwa a elastomeric. Nthawi zambiri amatulutsidwa kuchokera ku spool ya mamita 15. Kapangidwe kake kamalola dokotala kudula kutalika komwe kumafunika kuti kudutse mano angapo. Mwa kutambasula unyolo kuchokera pa bulaketi imodzi kupita ku ina, elastomer imasunga mphamvu zomwe zingatheke, zomwe zimatulutsidwa pang'onopang'ono kuti zikoke mano pamodzi.

Makhalidwe a zinthu ndi mphamvu

Zinthu zoyambira pa zinthu zonsezi nthawi zambiri zimakhalapolyurethane ya thermoplastic ya digiri ya zamankhwala, yosankhidwa chifukwa cha kulimba kwake kwakukulu, kukana kung'ambika, komanso kuuma kwa Shore A kwa 80 mpaka 90. Komabe, makhalidwe a mphamvu amadalira kwambiri kapangidwe ka zinthu ndi mawonekedwe enieni a chinthucho. Zambiri zokhudzana ndi zofunikira za chinthucho nthawi zambiri zimapezeka poyang'ana zolemba kuchokera kwa opanga aMa Ligature a Elastomeric.

Chizindikiro chofunikira cha elastomer iliyonse ya orthodontic ndi momwe imawola mphamvu yake. Ikatambasulidwa, ma polyurethane bond amayamba kumasuka. Kutengera makulidwe ndi njira yokhazikika yophikira ya chinthucho, unyolo wamagetsi wamba ukhoza kupereka mphamvu yoyambirira ya magalamu 300 mpaka 400 ikatambasulidwa kuwirikiza kawiri kutalika kwake kopumulira. Ma ligature amodzi amakhala ndi mphamvu yochepa kwambiri yokhala, nthawi zambiri pakati pa magalamu 100 ndi 200, zomwe zimakhala zokwanira kugwira waya popanda kumumangirira kwathunthu.

Kusiyana kwakukulu mwachidule

Kusiyana kwakukulu kuli pa mtunda wa ma module. Ma ligature amodzi ndi amodzi alibe mtunda, chifukwa salumikizidwa. Maunyolo amphamvu amapangidwa m'magawo atatu ofanana a filament: otsekedwa (palibe malo pakati pa mphete, pafupifupi 2.8mm kuchokera pakati kupita pakati), afupi (filament yaying'ono yolumikizira, pafupifupi 3.5mm), ndi yayitali (filament yayitali yolumikizira, pafupifupi 4.0mm).

Madokotala amasankha mtunda kutengera mtunda pakati pa mabulaketi ndi kuchuluka kwa mphamvu yomwe ikufunika. Unyolo wotsekedwa pa mabulaketi akuluakulu umatambasuka kwambiri, kupereka mphamvu zazikulu, pomwe unyolo wautali pa mano omwewo umapereka mphamvu yopepuka komanso yopitilira. Ma ligatures a munthu aliyense, opanda kulumikizana pakati pa mabulaketi, alibe mphamvu pakati pa mabulaketi.

Momwe Power Chains vs Elastomeric Ligatures Zikufananizira

Kuwunika momwe njira ziwirizi zomangira thupi zimagwirira ntchito kumafuna kusanthula kuwonongeka kwa mphamvu pakapita nthawi, mawonekedwe a chithandizo kuchipatala, komanso ndalama zogulira. Popeza nthawi zambiri ma orthodontics amasiyana ndi milungu 4 mpaka 8, zinthu zomwe zasankhidwa ziyenera kugwira ntchito bwino nthawi yonseyi popanda kufunikira kusinthidwa msanga.

Ngakhale kuti zinthu zonsezi zimakhala ndi zofooka za polyurethane m'malo onyowa, kugwiritsa ntchito kwawo kosiyanasiyana kumatanthauza kuti zofookazi zimaonekera mosiyana m'machitidwe azachipatala. Kuyerekeza kwathunthu kukuwonetsa kusiyana pakati pa kusunga mphamvu, kutsatira malamulo a odwala, ndi kayendetsedwe ka zinthu.

Kusunga ndi kugwira ntchito molimbika

Ma unyolo amphamvu ndi ma elastomeric ligatures onse amawola mphamvu mwachangu. Kafukufuku wa zachipatala nthawi zonse amasonyeza kuti ma polyurethane elastomer amataya pakati pa 50% ndi 70% ya mphamvu yawo yoyamba mkati mwa maola 24 oyamba atagwiritsidwa ntchito mkamwa. Pambuyo pa kuchepa koyamba kumeneku, mphamvuyo imachepa, ndikusunga pafupifupi 30% mpaka 40% (pafupifupi magalamu 100 mpaka 150) a mphamvu yake yoyambirira kwa milungu itatu mpaka inayi yotsalayo.

Popeza unyolo wamphamvu umayendetsa mano mwachangu, kuwola kwa mphamvu kumeneku kuyenera kuyang'aniridwa mosamala. Ngati unyolo utatambasulidwa kwambiri poyamba kuti ugwirizane ndi kuwola, ukhoza kuyambitsa hyalinization ya ligament ya periodontal, ndikuletsa kuyenda kwa dzino. Ma ligature amodzi, omwe amagwiritsidwa ntchito makamaka ngati zida zosungira, sakhudzidwa kwambiri ndi kuwola kumeneku, bola ngati asunga mphamvu zokwanira kuti archwire igwire bwino ntchito mu bracket slot.

Kusamalira, kupirira, ndi kuganizira za odwala

Kusamalira ndi kulimba kwa thupi kumakhudzidwa kwambiri ndi zakudya za wodwalayo komanso ukhondo wa mkamwa. Zinthu zonsezi zimatha kupakidwa utoto kuchokera ku khofi, tiyi, turmeric, ndi utsi. Komabe, chifukwa chakuti unyolo wamagetsi umaphimba malo akuluakulu ndipo umafalikira m'malo oyandikana, zimakhala zosavuta kugwira zotsalira za chakudya poyerekeza ndi ma ligatures osiyana.

Kulimba kwake ndi chifukwa chinanso, ndipo kuchuluka kwa kusweka kwa dzino nthawi zambiri kumakhala pansi pa 2% mpaka 3% pamwezi pa ma elastomer apamwamba. Ligature yosweka imakhudza dzino limodzi lokha, mwina kulola waya kutuluka mu bulaketi imodzi. Komabe, unyolo wamagetsi wosweka umasokoneza kwambiri njira yotsekera malo kwa gawo lonse, zomwe zimapangitsa kuti pakhale ulendo wadzidzidzi kuti apewe kubwereranso.

Zoganizira za mtengo ndi kupezeka

Poganizira za kugula, kapangidwe ka mtengo kamasiyana kwambiri. Ndi nthawi yokhazikika yoperekera chithandizo ya masabata awiri mpaka anayi, spool yokhazikika ya unyolo wamagetsi wa mapazi 15 nthawi zambiri imadula pakati pa $10 ndi $18, kutengera wopanga ndi mtundu wa zida. Spool imodzi imatha kutumikira odwala ambiri. Mosiyana ndi zimenezi, ma ligature a elastomeric nthawi zambiri amagulitsidwa m'mapaketi a 1,000 (nthawi zambiri ndodo 100 za 10), kuyambira $5 mpaka $12 pa paketi iliyonse.

Ngakhale mtengo wa wodwala aliyense pazinthu zonse ziwiri ndi wotsika (nthawi zambiri wochepera $0.50 pa arch), zipatala zambiri ziyenera kuganizira mtengo wonse, chifukwa ma elastomer amatha kukhala 5% mpaka 8% ya ndalama zonse zomwe zimagwiritsidwa ntchito. Kukhazikitsa zinthu zomwe zili m'gulu ndi mitundu yodalirika kungachepetse kwambiri ndalama zomwe zimagwiritsidwa ntchito komanso kupangitsa kuti zinthu zisamayende bwino.

Zimene Ogula ndi Madokotala Ayenera Kuwunika

Oyang'anira zogula ndi oyang'anira zachipatala ayenera kulinganiza bwino momwe zinthu zilili komanso momwe zinthu zilili komanso kutsatira malamulo. Kupeza ma elastomer a orthodontic si nkhani yongofuna kupeza mtengo wotsika kwambiri; kumafuna kuwunika mosamala zomwe zafotokozedwa mu malonda, chitetezo cha zinthu, komanso kudalirika kwa ogulitsa.

Kukhazikitsa njira zogulira zinthu kumaonetsetsa kuti ogwira ntchito zachipatala nthawi zonse amakhala ndi mwayi wopeza zinthu zomwe zimagwira ntchito bwino. Izi zimafuna njira yolongosoka yowunikira zinthu zatsopano musanagule zinthu zambiri m'mabungwe.
