Hauv kev kho hniav kho hniav, qhov tsis zoo ua rau muaj kev hloov kho, rov ua dua tshiab, thiab lub neej luv dua. CAD/CAM technology hloov qhov ntawd. Nws muab cov precision zoo sib xws ntawm qib micron. Ntau lub tsev kho mob thiab chaw kuaj mob tam sim no tso siab rau nws rau cov yas yas, txuas hniav, veneers, thiab cog kev kho dua tshiab.
Kab lus no piav qhia tias CAD / CAM yog dab tsi, yog vim li cas cov txheej txheem ib txwm poob qis, yuav ua li cas cov kev ua haujlwm digital ua tiav qhov raug zoo dua, kev sib piv ncaj qha nrog cov ntaub ntawv, thiab vim li cas thiaj li outsourcing rau ib qho chaw tshwj xeeb CAD / CAM feem ntau ua rau kev nkag siab zoo.
Dab tsi yog CAD / CAM Technology hauv Kev Kho Hniav?
CAD/CAM sawv cev rau Computer-Aided Design and Computer-Aided Manufacturing. Hauv kev kho hniav, nws tsim kev kho dua tshiab los ntawm cov ntaub ntawv digital es tsis txhob siv cov kauj ruam.
Cov txheej txheem tawg mus rau hauv peb qhov tseem ceeb:
- Digital scanning captures qhov kev npaj thiab occlusion.
- CAD software tsim kev kho kom zoo dua qub.
- CAM cov cuab yeej mills lossis luam tawm qhov kawg ntawm cov ntaub ntawv xws li zirconia, lithium disilicate, lossis cov khoom sib xyaw.
Intraoral scanners lossis lab scanners muab siab - cov ntaub ntawv daws teeb meem, feem ntau nqes mus rau microns. Tsim software tso cai rau kev tswj hwm lub cev, tuab, thiab kev sib cuag. CAM siv 5-axis milling tshuab rau cov duab nyuaj nrog qhov yuam kev tsawg heev.
Qhov no siv tau rau ib leeg crowns, txuas hniav, veneers, inlays, onlays, thiab cog abutments. Cov ntaub ntawv nyob sib xws nyob rau hauv lub system.
Qhov tshwm sim yog repeatable precision uas phau ntawv qhia tawm tsam kom phim.

Cov txheej txheem ib txwm cia siab rau lub cev kev xav, qauv pob zeb, thiab tes- ua qauv.
Cov dej ntws mus zoo li no: coj lub tswv yim silicone, ncuav pob zeb qauv, tsim cov quav ciab- nce, nqis peev, cam khwb cia hlau moj khaum, txheej porcelain, sinter.
Txhua kauj ruam qhia txog qhov yuam kev:
Impression khoom shrinks los yog distorts.
- Pob zeb nthuav me ntsis thaum teeb tsa.
- Wax qauv warp nrog kub hloov.
- Tes waxing los yog casting accumulates tib neeg variation.
Cov no ntxiv. Marginal gap feem ntau muaj li ntawm 80 mus rau 200 microns lossis ntau dua. Sab hauv haum raug kev txom nyem ib yam nkaus, nrog cov cement tsis sib xws.
Cov teeb meem kev kho mob raws li nram no: tsis zoo marginal foob ua rau muaj kev pheej hmoo ntawm cov kab mob caries, ntau cov cement ua rau mob, nquag hloov kho occlusal, ntau dua remake tus nqi.
Cov kev tshawb fawb qhia pom qhov sib txawv ntawm qhov sib txawv feem ntau tshaj 100 microns, qee zaum ncav cuag 200+ microns hauv qhov tseeb.
Cov kev txwv no thawb kev lag luam mus rau cov kev daws teeb meem digital.
Yuav ua li cas CAD/CAM Workflow ua tiav siab dua Precision
CAD/CAM tshem tawm feem ntau qhov yuam kev los ntawm kev mus rau digital ntxov.
Kev ua haujlwm tiav:
- Luam theej duab qhov kev npaj ncaj qha rau hauv lub qhov ncauj nrog ib qho intraoral scanner los yog luam theej duab tus qauv hauv chav kuaj. Kev daws teeb meem ncav cuag 10-20 microns, tsis muaj cov khoom sib txawv.
- Import cov ntaub ntawv rau CAD software. Tsim cov kev kho dua tshiab nrog cov npoo npoo, occlusion, thiab lub cev. Kev hloov kho virtual ntes teeb meem ua ntej tsim khoom.
- Xa cov ntaub ntawv mus rau CAM. Lub 5-axis zeb txiav qhov khoob qhov tseeb, lossis lub tshuab luam ntawv 3D tsim nws txheej los ntawm txheej. Automation tshem tawm tes variability.
Cov neeg tsav tsheb tseem ceeb ntawm qhov tseeb:
- Tsis muaj kev xav shrinkage lossis qauv nthuav dav.
- Cov qauv tsim digital tswj txhua micron ntawm cov npoo thiab sab hauv.
- Precise machining tuav kam rau siab tshaj 50 microns nyob rau hauv ntau rooj plaub.
Cov tshuab niaj hnub tsim cov qhov sib txawv ntawm 20-70 microns niaj hnub. Sab hauv haum ua kom zoo ib yam, txo cov voids thiab txhim kho cement tis.
Qhov kev ua haujlwm no muab qhov sib xws ntawm cov xwm txheej thiab cov kws tshaj lij.
CAD/CAM vs. Traditional: Qhov tseeb sib piv
Cov ntaub ntawv los ntawm ntau qhov kev tshawb fawb qhia meej qhov sib txawv. Nov yog cov ntsiab lus sib piv raws li kev tshawb fawb luam tawm:

Kev tshawb fawb (egPhau ntawv Journal of Prosthetic Dentistry, PubMed tshuaj xyuas) qhia txog cov kev xav digital thiab CAD/CAM cov yas yas nrog qhov sib txawv ntawm 26-60 µm, piv rau 49-209 µm rau cov pa. Tsib-axis tshuab thawb cov npoo txawm qis dua, qee zaum qis dua 20 µm hauv kev teeb tsa zoo.
Direct digital scans outperform indirect ones nyob rau hauv ntau rooj plaub. Zuag qhia tag nrho, CAD / CAM haum nyob rau hauv kev kho mob tau txais kev ntseeg siab dua.
Kev txo qhov sib txawv txhais tau tias muaj kev hloov kho tsawg dua, kev ua neej zoo dua, thiab cov neeg mob zoo siab dua.
Vim li cas Outsource mus rau Tshwj Xeeb CAD/CAM Dental Lab?
Ntau qhov kev coj ua tsis txaus siab los nqis peev hauv tag nrho hauv -house CAD/CAM. Scanners, mills, software, thiab cov neeg ua haujlwm cob qhia raug nqi hnyav. Volume tej zaum yuav tsis pom zoo rau nws.
Outsourcing rau ib lub chaw kuaj mob siab daws qhov no.
Cov txiaj ntsig muaj xws li:
Nkag mus rau sab saum toj- cov cuab yeej siv qib siab thiab pab pawg kws tshaj lij yam tsis muaj peev nyiaj siv.
- Tsawg dua ib -unit nqi thaum ua kom siab precision.
- Qhov zoo ib yam los ntawm kev ua haujlwm tshwj xeeb thiab kev kuaj xyuas zoo.
- Kev hloov pauv sai ntawm cov ntaub ntawv hloov pauv (STL cov ntaub ntawv xa tam sim).
- Tsom ntsoov rau kev saib xyuas tus neeg mob tsis yog kev tsim khoom.
Rau cov kws kho mob txawv teb chaws, cov chaw sim hauv Suav teb nrog cov kev teeb tsa digital muaj zog muaj kev xaiv txhim khu kev qha. Lawv siv thoob ntiaj teb- cov tshuab thiab cov khoom siv. Precision qhov sib tw lossis tshaj qhov chaw sim hauv zos hauv ntau qhov ntsuas. Turnaround nyob twj ywm kev sib tw, feem ntau 5-10 hnub ua haujlwm.
NtawmADS Dental Laboratory Ltd, peb tsom mus rau lub sijhawm ntev - outsourcing rau cov neeg siv khoom txawv teb chaws. Peb cov txheej txheem CAD/CAM muab cov khoom ruaj khov, siab - raug kho kom raug. Cov ntaub ntawv digital ua kev sib koom tes ncaj nraim.
