PMMA Dental yog dab tsi

PMMA hniav dawb paug yog qhov ruaj khov thiab ruaj khov PMMA (polymethyl methacrylate) milling thaiv rau kev kho ib ntus. Nws muaj qhov nqus dej tsawg thiab solubility, muab siab ntev -lub sij hawm stability thiab homogeneity. PMMA block tsis muaj tshuaj lom lossis ua xua, tuaj yeem siv rau hauv lub qhov ncauj ntev, yooj yim rau zom thiab txhuam, thiab tuaj yeem pleev xim los yog txheej rau kev zoo nkauj tshaj plaws. Cov txheej txheem kho dua tshiab ib ntus yog tsim los ntawm CAD txheej txheem nrog cov ntaub ntawv intraoral lossis impression thiab tom qab ntawd tsim los ntawm milling system.

Polymethylmethacrylate (PMMA) feem ntau yog siv rau hauv daim ntawv thov kho hniav. Feem ntau xav txog nyob rau hauv kev tsim cov hniav cuav, orthodontic retainers, ib ntus yas, thiab cov hniav hauv qab. Tab sis tsis txwv rau qhov kev thov no. PMMA muaj cov khoom tshwj xeeb ntawm kev ceev faj qis, kev ua kom zoo nkauj, thiab cov kws kho tshuab lossis cov ntaub ntawv zoo thiab nrov rau kev kho hniav.

Kev ua haujlwm ntawm PMMA:

• Kev ua haujlwm thermal

• nqus dej

• Solubility

• Kev cuam tshuam lub zog

• Khoov zog

Thawj qhov kev siv ntawm polymethyl methacrylate (PMMA) ua cov cuab yeej kho hniav yog rau kev tsim cov hniav cuav. Nws cov txiaj ntsig ntawm biocompatibility, kev ntseeg tau, txheeb ze yooj yim ntawm kev tswj hwm, thiab tsis muaj tshuaj lom tau sai sai tau ntes thiab koom nrog ntau yam kev kho mob tshwj xeeb.
