Ultra-Zoo Zirconia Debinding-Sintering Technology Qhib Lub Sijhawm Tshiab Ntawm Tib -Hnub Kho Hniav

Ib qho kev txiav-ntev thev naus laus zis los ntawm University of Texas ntawm Dallas tau rhuav tshem lub sijhawm ntev - lub sijhawm ua haujlwm ntawm 3D luam tawm zirconia kho dua tshiab, coj cov kev hloov pauv rau kev tsim kho hniav digital. Pab neeg tshawb fawb tau ua tiav lub hom phiaj kev ua kom zoo rau cov txheej txheem kev debinding thiab sintering siv rau cov khoom siv zirconia ntxiv, txhim kho tag nrho cov txheej txheem thermal ua haujlwm rau kev kho hniav ceramic.

Tsoos 3D luam tawm zirconia crowns thiab txuas hniav yuav tsum tau ted heev thiab sij hawm -siv cov txheej txheem thermal. Cov txheej txheem ua tiav ntawm kev tshem tawm cov ntaub ntawv polymer los ntawm kev debinding thiab ua tiav cov ntaub ntawv densification ntawm siab - kub sintering yav dhau los yuav siv sij hawm ntau tshaj 100 teev nyob rau hauv tag nrho. Xws li ultra- lub voj voog ntau lawm ib txwm yog qhov teeb meem tseem ceeb txwv kev kho hniav hauv lub rooj zaum, ua tib yam -hnub xa cov zirconia mus tas li rov qab ua tsis tau thiab yuam cov neeg kho mob feem ntau cia siab rau tawm ntawm- chaw soj ntsuam ntau lawm nrog ntau- lub sijhawm tos sijhawm.

Cov txheej txheem ua kom zoo dua tshiab tau ua tiav qhov kev ua tau zoo txaus ntshai los ntawm kev ua kom zoo dua qhov ntsuas kub, lub voj voog cua sov thiab kev tswj hwm huab cua. Lub sijhawm ua haujlwm thermal tag nrho rau cov ntawv luam tawm zirconia yog luv luv los ntawm ntau dua 100 teev mus rau tsawg dua 30 feeb, uas txo qis lub sijhawm tsim khoom, txo cov khoom siv thiab txo cov nqi ua haujlwm tag nrho. Qhov tseem ceeb, cov thev naus laus zis tshiab ruaj khov tswj cov khoom siv zoo heev, cov qauv ntom ntom, biocompatibility thiab kev ua kom zoo nkauj ntawm siab -tus qauv kho hniav zirconia, kom ntseeg tau qhov chaw kho mob siv tau thiab ua haujlwm ntev ntawm kev kho tiav tiav.

Lub hom phiaj tseem ceeb ntawm kev tshawb fawb ntawm cov thev naus laus zis no yog kom paub txog cov rooj zaum uas paub tab tib yam -hnub tsim cov zirconia crowns thiab txuas hniav. Nyob rau hauv lub neej yav tom ntej, cov chaw kho hniav tuaj yeem ua tiav intraoral scanning, digital design, 3D printing thiab integrated ceev thermal post- ua tiav hauv ib qho kev mus ntsib, ua rau cov neeg mob tau txais kev kho kom ruaj khov rau ntawm qhov chaw yam tsis muaj kev rov mus xyuas dua lossis lub sijhawm tos ntev.

Tam sim no, qhov no ultra- nrawm debinding-sintering innovation tseem nyob rau theem kev lag luam loj hlob. Cov pab pawg muaj feem cuam tshuam txuas ntxiv ua cov kev sim tshuaj, cov txheej txheem kev kuaj xyuas tus qauv thiab txhawb nqa cov cuab yeej siv los daws cov teeb meem sib txuam ntawm cov khoom tsim tawm thiab kev kho mob nrov. Thaum tag nrho kev lag luam thiab kev txhawb nqa, thev naus laus zis yuav hloov kho tag nrho cov kev tsim kho ntawm cov zirconia ruaj khov kho, txhim kho kev ua haujlwm zoo ntawm kev kho hniav niaj hnub, thiab muab kev yooj yim dua, muaj txiaj ntsig thiab siab -kev kho mob zoo rau cov chaw kho hniav thoob ntiaj teb thiab cov neeg mob.
