Buku Lotsogolera Kusankha Waya wa Mano: Kodi Ma Arches Osiyana Amagwirira Ntchito Motani Pa Chithandizo cha Orthodontic?

Pa chithandizo cha mano, mawaya a orthodontic archwall amachita gawo lofunika kwambiri ngati "oyendetsa osawoneka". Mawaya achitsulo ooneka ngati osavuta awa ali ndi mfundo zenizeni za biomechanical, ndipo mitundu yosiyanasiyana ya mawaya a archwall amachita ntchito zapadera m'magawo osiyanasiyana owongolera. Kumvetsetsa kusiyana kwa ulusi wa mano awa kungathandize odwala kumvetsetsa bwino njira yawo yowongolera.

1, Mbiri ya Chisinthiko cha Zipangizo za Uta Waya: Kuchokera ku Chitsulo Chosapanga Dzimbiri mpaka ku Alloys Anzeru
Mawaya amakono a orthodontic arch amagawidwa m'magulu atatu a zipangizo:

Waya wosapanga dzimbiri: katswiri pa ntchito ya orthodontics, wamphamvu kwambiri komanso wokwera mtengo

Waya wa archwire wa Nickel titanium alloy: wokhala ndi mawonekedwe okumbukira komanso kusinthasintha kwabwino kwambiri

β - Waya wa Titanium Alloy Bow: Nyenyezi Yatsopano Yogwirizana Bwino Pakati pa Kusinthasintha ndi Kulimba

Pulofesa Zhang, Mtsogoleri wa Dipatimenti ya Orthodontics ku Peking University Stomatological Hospital, adayambitsa kuti, "M'zaka zaposachedwa, kugwiritsa ntchito mawaya a nickel titanium omwe amagwiritsidwa ntchito ndi kutentha kwafalikira kwambiri. Waya wa arch uwu ukhoza kusintha mphamvu ya orthodontic yokha kutentha kwa mkamwa, zomwe zimapangitsa kuti kuyenda kwa dzino kugwirizane ndi mawonekedwe a thupi.

2, magawo a chithandizo ndi kusankha waya wa archwire: luso lopita patsogolo
Gawo lolinganiza (gawo loyambirira la chithandizo)

Waya wozungulira wa titaniyamu wa hyperelastic nickel womwe umagwiritsidwa ntchito kwambiri (0.014-0.018 mainchesi)

Mawonekedwe: Mphamvu yowongolera yofatsa komanso yopitilira, yothandiza kuchepetsa kutsekeka kwa anthu

Ubwino wa zachipatala: Odwala amatha kusintha msanga ndipo amamva ululu wochepa

Gawo lolinganiza (chithandizo chapakati)

Waya wopangira titaniyamu wa nickel wozungulira (0.016 x 0.022 mainchesi)

Ntchito: Yang'anirani malo oyima a mano ndikukonza kutsekeka kwakuya kwa mano

Zatsopano zaukadaulo: Kapangidwe ka mphamvu ya gradient kuti mupewe kusungunuka kwa mizu

Gawo lokonzanso bwino (gawo lomaliza la chithandizo)

Kugwiritsa ntchito waya wachitsulo chosapanga dzimbiri (0.019 x 0.025 mainchesi)

Ntchito: Yang'anirani bwino malo a muzu wa dzino ndikukonza ubale wa kuluma

Kupita patsogolo kwaposachedwa: Waya wa digito wopangidwa kale umathandizira kulondola

3, Ntchito yapadera ya mawaya apadera
Waya wopindika kwambiri: wogwiritsidwa ntchito poyendetsa mano movutikira

Uta wa mpando wogwedezeka: wopangidwa mwapadera kuti akonze zophimba zakuya

Uta wa zidutswa: chida chosinthira bwino madera am'deralo

Monga momwe openta amafunikira maburashi osiyanasiyana, madokotala a mano amafunikanso mawaya osiyanasiyana kuti akwaniritse zosowa zosiyanasiyana za mano, "anatero Mtsogoleri Li wa Dipatimenti ya Mano

Chipatala chachisanu ndi chinayi cha Shanghai.

4, Chinsinsi cha Kusintha Waya wa Uta
Kusinthasintha kwa nthawi zonse:
Choyamba: Sinthani milungu 4-6 iliyonse
Pakati pa gawo mpaka kumapeto: sinthani kamodzi pa masabata 8-10 aliwonse
Zinthu zomwe zimakhudza:
Mulingo wotopa wa zinthu
Kupita patsogolo kwa chithandizo
Malo olankhulira odwala

5, Mafunso ndi Mayankho Omwe Amafunsidwa Kawirikawiri kwa Odwala
Q: N’chifukwa chiyani waya wanga wa archwire umandibaya pakamwa nthawi zonse?
Yankho: Zochitika zofala panthawi yoyamba yosinthira zitha kuchepetsedwa pogwiritsa ntchito sera ya orthodontic
Q: N’chifukwa chiyani waya wa archwall umasintha mtundu?
A: Chifukwa cha kuyika utoto wa chakudya, sichikhudza zotsatira za chithandizocho.
Q: Nanga bwanji ngati waya wa arch wasweka?
A: Lumikizanani ndi dokotala nthawi yomweyo ndipo musachite nokha

6, Zochitika Zamtsogolo: Nthawi ya archwire yanzeru ikubwera
Ukadaulo watsopano mu kafukufuku ndi chitukuko:
Waya wozindikira mphamvu: kuyang'anira mphamvu yokonza nthawi yeniyeni
Mankhwala otulutsa archwire: kupewa kutupa kwa genival
Waya wowola: chisankho chatsopano chosawononga chilengedwe

7, Malangizo a akatswiri: Kusankha mwamakonda ndikofunikira
Akatswiri amati odwala:
Musayerekezere nokha makulidwe a waya wa archwire
Tsatirani malangizo a dokotala mosamala ndipo konzani nthawi yokumana ndi dokotala pa nthawi yake
Gwirizanani ndi kugwiritsa ntchito zipangizo zina zochizira mano
Sungani ukhondo wabwino wa pakamwa

Ndi chitukuko cha sayansi ya zinthu, mawaya a orthodontic akupita ku njira zanzeru komanso zolondola. Koma ngakhale ukadaulowo utakhala wotani, njira zomwe munthu payekhapayekha zomwe zimagwirizana ndi vuto la wodwala aliyense ndiye chinsinsi chopezera zotsatira zabwino zowongolera. Monga momwe katswiri wamkulu wa orthodontic ananenera, "Waya wabwino uli ngati chingwe chabwino, koma m'manja mwa 'wochita' waluso ndi momwe konsati ya mano yabwino ingaseweredwere."
