Ubwino wa TPU poyerekeza ndi Zida Zina (monga PETG) mu Orthodontics

Ubwino waTPUpa Zida Zina (monga PETG) muMadokotala a mano

Mu gawo la orthodontics, ma polima atatu akuluakulu a thermoplastic - TPU, PETG, ndi PCTG - ali ndi makhalidwe osiyanasiyana. Mwachidule: TPU imachita bwino kwambiri pa "kupirira" ndi "kulimba"; PETG ndi yabwino kwambiri pa "kuwonekera bwino kwambiri"; PCTG imadziwika ndi "kulimba kwake kofewa komanso kosatha". Kusiyana kwake ndi ubwino wake ndi motere:

TPU vs. PETG vs. PCTG: Kuyerekeza Magwiridwe Abwino Kwambiri

1. Katundu Woyambira: Kuyambira Kulimba mpaka Kuwonekera

2. Kusiyana Kwakukulu kwa Zaukadaulo: Mphamvu Zopepuka ndi Zolemera

• Kuuma Koyamba (Kukana Kusintha): TPU > PETG > PCTG
  TPU imapereka mphamvu yoyambirira kwambiri pa mano; PCTG imapereka mphamvu zochepa kwambiri, zomwe zimapangitsa kuti ikhale yoyenera pazigawo zosiyanasiyana za chithandizo.
• Kusunga Mphamvu (Kupumula Kupsinjika): Pambuyo pa masiku 14, PCTG imasonyeza kuchepa kwa kupsinjika pang'onopang'ono, kupereka mphamvu "yopepuka koma yokhazikika".
• Mphamvu Yong'ambika: TPU > PETG > PCTG. Kusiyana kwakukulu kukusonyeza kuti TPU ndi yolimba kwambiri kung'ambika kapena kuwonongeka ndi mphamvu zakunja - chizindikiro chachikulu cha kulimba.

3. Kusintha kwa Mphamvu Kwa Nthawi Yaitali (Njira Yopumulira Kupsinjika)

• PCTG: Kupsinjika maganizo kumakhazikika pambuyo pa tsiku limodzi logwiritsidwa ntchito.
• TPU ndi PETG: Kupsinjika maganizo kumachepa kwambiri pakati pa tsiku loyamba ndi lachisanu ndi chiwiri, kenako kumakhazikika.
  Nthawi yosinthira yomwe ingaperekedwe: Masiku 3-7 kuti muwonetsetse kuti mano akugwira ntchito bwino komanso mosalekeza.

4. Kugwirizana kwa Zamoyo ndi Kukhalitsa

• Kugwirizana kwa zinthu: Kafukufuku waposachedwa akuwona kuti zinthu zonse zitatuzi zimagwirizana ndi zinthu zina. Ovala amakonda TPU kuti ikhale yomasuka komanso PETG kuti ikhale yowonekera bwino komanso yolimba.
• Zotsatira Zachilengedwe pa Tizilombo Tosaoneka ndi Matupi Opakamwa: PETG ikuwonetsa zotsatira zazikulu. Kafukufuku akusonyeza kuti patatha maola 4 ogwiritsidwa ntchito mosalekeza, PETG imayambitsa kuchepa kwakukulu kwa pH ya malovu, ndipo patatha maola 8, kusintha kwa microflora ya mano kumaonekera. Zotsatira za TPU zimachedwa kwambiri (maola 12-24), zomwe zingapereke "chitetezo" cha nthawi yayitali pakuwongolera tizilombo pamwamba pa zinthuzo.

Chidule & Malangizo Osankha

Chifukwa chake,TPUUbwino waukulu wa orthodontics ndi awa:

• Kulimba kwambiri komanso kulimba: Kulimba kwambiri polimbana ndi kusweka ndi kusweka - ma aligners satha kusweka nthawi iliyonse akamawonongeka ndi kuchotsedwa tsiku ndi tsiku.
• Mphamvu yoyambira kwambiri yopangira mano: Ikhoza kugwiritsa ntchito mphamvu yochulukirapo pa mano, yoyenera gawo loyamba la chithandizo.
• Kusunga ndalama: Kulimba kwambiri kumachepetsa chiopsezo cha kuwonongeka; kukhazikika bwino kwa mawonekedwe kungafunike kusintha pang'ono.

Mosiyana ndi zimenezi, PCTG ili ndi mphamvu yochepa yoyambira koma mphamvu yokhazikika yosungira, yoyenera kugwiritsidwa ntchito pambuyo pake pochiza kapena kusintha bwino. PETG imapereka mgwirizano wabwino pakati pa kuwonekera bwino ndi magwiridwe antchito onse.
