Chingwe cha mano: chipangizo chofunikira chomangirira mano pochiza mano

1. Tanthauzo la malonda ndi malo ogwirira ntchito

Chingwe cha orthodontic ndi chipangizo chapadera chomwe chimagwiritsidwa ntchito pokonza molar mu machitidwe okhazikika a orthodontic, chomwe chimapangidwa kuchokera ku chitsulo chosapanga dzimbiri chachipatala. Monga gawo lofunikira la kukhazikika mu dongosolo la orthodontic mechanics, ntchito zake zazikulu ndi izi:
Perekani thunthu lokhazikika la mphamvu ya orthodontic

Tengani zinthu monga machubu a buccal
Gawani katundu wa occlusal
Tetezani minofu ya mano

Lipoti la msika wapadziko lonse wa zida zamano la 2023 likuwonetsa kuti zinthu zogwiritsidwa ntchito ndi band-on zikugwiritsabe ntchito 28% pakati pa zowonjezera za orthodontic, makamaka pazifukwa zovuta zomwe zimafuna kukhazikika mwamphamvu.

2. Magawo Aukadaulo Apakati

Makhalidwe a zinthu
Kugwiritsa ntchito chitsulo chosapanga dzimbiri chachipatala cha 316L
Makulidwe: 0.12-0.15mm
Mphamvu yotulutsa ≥ 600MPa
Chiŵerengero cha kutalika ≥ 40%

Kapangidwe ka Kapangidwe
Dongosolo la kukula lomwe lapangidwa kale (lomwe limagwiritsidwa ntchito kwambiri pa nambala 18-32 mu molars yoyamba)
Kapangidwe ka pamwamba kozungulira bwino
Kapangidwe ka mafunde pamphepete mwa gingival
Batani la chubu cha buccal/chilankhulo cholumikizidwa kale

Chithandizo cha Pamwamba
Kupukuta kwamagetsi (kukhwima kwa pamwamba pa Ra≤0.8μm)
Chithandizo chopanda nikeli
Chophimba choletsa ma plaque (ngati mukufuna)
3. Kusanthula Ubwino Wachipatala

Katundu wabwino kwambiri wamakina
Wokhoza kupirira mphamvu ya orthodontic ya 500-800g
Kukana kusintha kwa zinthu ndi kokwera katatu kuposa kwa mtundu wa mgwirizano
Yoyenera kugwiritsa ntchito makina amphamvu monga kugwirira ntchito pakati pa maxillary

Kukhazikika kwa nthawi yayitali
Nthawi yogwiritsira ntchito ndi zaka 2-3
Kugwira ntchito bwino kwambiri potseka m'mphepete (kutuluka kwa madzi pang'ono <50μm)
Kukana dzimbiri kwapadera

Kusintha kwa milandu yapadera
Mano okhala ndi enamel hypoplasia
Kukonzanso malo akuluakulu opukutira molar
Kufunika kwa opaleshoni ya orthognathic yokhazikika
Milandu yomwe imafuna anthu oyenda mwachangu

4. Kusintha kwa ukadaulo wamakono

Ukadaulo wosintha zinthu pa digito
Kupanga chitsanzo cha pakamwa ndi kusindikiza kwa 3D
Kusintha kwa makulidwe opangidwa ndi munthu payekha
Kubwerezabwereza kolondola kwa mawonekedwe a pamwamba pa occlusal

Mtundu wokonzedwa bwino mwachilengedwe
Mphete yotulutsa fluoride
Chophimba cha ayoni yasiliva chotsutsana ndi mabakiteriya
Mphepete mwa galasi logwira ntchito

Dongosolo lothandizira losavuta
Chitoliro cha buccal cha torque chokhazikitsidwa kale
Chipangizo chokokera chochotseka
Kapangidwe kodzitsekera

"Ukadaulo wamakono wopangira mabande wasintha kuchoka pa kungokonza makina kupita ku njira yothetsera mavuto yomwe imagwirizanitsa kugwirizana kwa thupi, kuwongolera makina, ndi chisamaliro chaumoyo chodzitetezera. Posankha zachipatala, ndikofunikira kuganizira bwino za matenda a mano, mapulani a orthodontic, ndi malo olankhulirana a wodwala. Ndikofunikira kugwiritsa ntchito zinthu zomwe zapangidwa mwamakonda kuti zikwaniritse zotsatira zabwino kwambiri."
– Pulofesa Wang, Wapampando wa Bungwe la Madokotala a Mano a ku China
Ma bandeji a mano, monga ukadaulo wakale wotsimikiziridwa kwa zaka zoposa makumi asanu, akupitilizabe kukonzedwanso ndi mphamvu ya digito ndi ukadaulo wa biomaterial. Ubwino wake wosasinthika wamakina umapangitsa kuti ikadali ndi udindo wofunikira pa chithandizo cha mano chovuta, ndipo ipitilizabe kutumikira zipatala za mano kudzera m'njira zolondola komanso zosawononga kwambiri mtsogolo.
