US Dental University Tsim Novel Antimicrobial Photocurable Denture Polymer
Oct 07, 2026
Cov kws tshawb fawb ntawm ib lub tsev kawm ntawv kho hniav hauv Asmeskas tab tom tsim cov duab tshuaj tiv thaiv kab mob tshiab- kho tau cov polymer uas haum rau kev tsim cov hniav cuav. Trace antibacterial additives yog incorporated ncaj qha mus rau hauv lub resin matrix thaum lub sij hawm 3D luam ntawv txheej txheem. Cov khoom tsim tshwj xeeb tuaj yeem tiv thaiv kev loj hlob ntawm cov kab mob thiab cov fungi nyob rau saum npoo ntawm cov ntawv luam tawm.
Cov ntaub ntawv zoo nkauj acrylic cov ntaub ntawv raug kev txom nyem los ntawm lub qhov dej -cov ntaub ntawv tsis zoo: lawv qhov chaw zoo li ntxiab cov khib nyiab hauv qhov ncauj thiab tsim cov ntaub ntawv biofilm dhau sijhawm. Rau cov neeg siv cov hniav nyiaj hniav kub, cov khoom siv biofilm yog qhov ua rau muaj ntau yam teeb meem ntawm qhov ncauj, nrog rau gingival irritation, halitosis tsis tu ncua thiab hniav stomatitis. Cov teeb meem no txo qhov kev nplij siab ntawm tus neeg mob thiab tuaj yeem ua rau rov qab kho dua tshiab -ups.
Los ntawm embedding cov tshuaj tua kab mob hauv cov resin es tsis yog siv cov txheej txheem saum npoo av, cov khoom tshiab zam kev pheej hmoo ntawm cov khoom xyaw nquag hnav los ntawm txhua hnub txhuam thiab mastication. Nws muab cov teebmeem inhibitory tiv thaiv kev loj hlob ntawm microbial thaum khaws cia cov khoom siv kho tshuab, xim ruaj khov thiab biocompatibility xav tau rau kev kho hniav prostheses.
Yog tias ua tiav kev lees paub los ntawm kev txuas ntxiv hauv - kev sim vitro thiab kev sim tshuaj, daim duab no -polymer kho tau yuav ua rau muaj txiaj ntsig zoo rau 3D luam tawm cov hniav cuav. Nws tuaj yeem txo qis qhov tshwm sim ntawm biofilm- ntsig txog kab mob hauv qhov ncauj ntawm cov neeg mob hniav thiab nthuav dav cov txiaj ntsig zoo ntawm kev tsim cov khoom siv digital additive hauv cov khoom siv tes taw tshem tau.
