Cov txiaj ntsig ntawm TPU dua lwm cov ntaub ntawv (piv txwv li, PETG) hauv Orthodontics

Cov txiaj ntsig ntawmTPUdhau lwm yam khoom siv (piv txwv li, PETG) hauvKev Kho Hniav

Hauv kev kho hniav, peb hom thermoplastic polymers - TPU, PETG, thiab PCTG - muaj cov yam ntxwv sib txawv. Hauv ntej: TPU zoo heev hauv "kev ua siab ntev" thiab "kev tawv"; PETG zoo dua hauv "kev pom tseeb siab"; PCTG paub txog nws "mos thiab ruaj khov elasticity". Qhov sib txawv thiab qhov zoo tshwj xeeb yog raws li nram no:

TPU piv rau PETG piv rau PCTG: Kev Sib Piv Txog Kev Ua Tau Zoo

1. Cov Khoom Tseem Ceeb: Txij Li Qhov Ruaj Khov Mus Rau Qhov Pom Tseeb

2. Qhov Txawv Tseem Ceeb ntawm Kev Siv Tshuab: Lub Zog Sib piv rau Lub Zog Hnyav

• Kev Nyuaj Siab Thaum Pib (Kev Tiv Thaiv Kev Hloov Pauv): TPU > PETG > PCTG
  TPU muab lub zog pib loj tshaj plaws rau cov hniav; PCTG muab qhov tsawg tshaj plaws, ua rau nws haum rau ntau theem kev kho mob.
• Kev Khaws Lub Zog (Kev So Kom Nyuaj Siab): Tom qab 14 hnub, PCTG qhia txog kev poob qis qeeb tshaj plaws, xa lub zog "me me tab sis ruaj khov".
• Lub Zog Tsim Tawm: TPU > PETG > PCTG. Qhov sib txawv tseem ceeb qhia tau tias TPU yog qhov tiv taus tshaj plaws rau kev tsim kua muag lossis kev puas tsuaj nyob rau hauv lub zog sab nraud - qhov qhia tseem ceeb ntawm kev ruaj khov.

3. Kev Hloov Pauv Lub Zog Mus Ntev (Kev Txo Kev Nyuaj Siab)

• PCTG: Kev ntxhov siab ruaj khov tom qab 1 hnub hnav.
• TPU thiab PETG: Kev ntxhov siab txo qis ntawm hnub 1 thiab hnub 7, tom qab ntawd ruaj khov.
  Lub voj voog hloov kho uas pom zoo: 3–7 hnub kom ntseeg tau tias lub zog orthodontic txuas ntxiv mus thiab ua haujlwm tau zoo.

4. Kev sib haum xeeb thiab kev ruaj khov

• Kev sib haum xeeb ntawm lub cev: Cov kev tshawb fawb tam sim no xav txog tag nrho peb yam khoom siv uas sib haum xeeb ntawm lub cev. Cov neeg hnav nyiam TPU rau kev nplij siab thaum xub thawj thiab PETG rau kev pom tseeb thiab kev ruaj khov.
• Kev Cuam Tshuam Ib Puag Ncig rau Cov Kab Mob Hauv Qhov Ncauj: PETG qhia tau tias muaj kev cuam tshuam loj dua. Cov kev tshawb fawb qhia tau tias tom qab 4 teev ntawm kev hnav tas li, PETG ua rau pom tseeb hauv pH salivary, thiab tom qab 8 teev, kev hloov pauv meej meej hauv cov kab mob hauv cov hniav. TPU cov teebmeem qeeb dua (12-24 teev), tej zaum yuav muab "lub qhov rais kev nyab xeeb" ntev dua rau kev tswj cov kab mob ntawm cov khoom siv.

Cov Lus Qhia Txog Kev Xaiv thiab Cov Lus Qhia Txog Kev Xaiv

Yog li ntawd,TPUmuaj cov txiaj ntsig sib txawv hauv kev kho hniav orthodontics:

• Kev ruaj khov thiab ua tau ntev tshaj plaws: Kev tiv taus siab tshaj plaws rau kev rhuav thiab tawg - cov aligners yuav tsis tawg thaum hnav thiab tshem tawm txhua hnub.
• Lub zog orthodontic pib siab tshaj plaws: Muaj peev xwm siv lub zog ntau dua rau cov hniav, tsim nyog rau theem pib ntawm kev kho mob.
• Tus nqi tsim nyog: Kev ruaj khov siab txo qhov kev pheej hmoo ntawm kev puas tsuaj; kev ruaj khov zoo yuav xav tau tsawg dua qhov hloov pauv.

Qhov sib txawv, PCTG muaj lub zog pib qis dua tab sis lub zog khaws cia ruaj khov, tsim nyog rau cov theem kho tom qab lossis kev hloov kho me me. PETG muab qhov sib npaug zoo ntawm kev pom tseeb thiab kev ua tau zoo tag nrho.
