Yuav Siv Daim Ntawv Kho Hniav Li Cas?
Daim Ntawv Kho Hniav Cov Ntawv Ua Ntej Ib lub luag haujlwm tseem ceeb hauv kev kho hniav txoj kev kho hniav rov qab, tshwj xeeb yog nyob rau hauv kev kho ntawm cov neeg txhais lus. Ntawm no yog cov kauj ruam tshwj xeeb rau kev siv daim ntawv kho hniav:
I. Npaj Theem
Xaiv cov khoom tsim nyog matrix: Xaiv cov kev sib tw loj uas haum raws li qhov chaw thiab qhov loj ntawm cov hniav tsis xws luag los yog caries. Cov ntawv zoo li xws li suav nrog puag ncig, xwm txheej, thiab sawb-puab cov ntawv txheeb.
NPAJ cov cuab yeej: sib sau cov cuab yeej thiab cov khoom siv xws li cov khoom siv hluav taws xob, cov khoom siv noo noo, cov tshuaj pleev lub teeb ci, thiab lwm yam.
Ii. Cov kauj ruam kev ua haujlwm
Qhib lub nplhaib retainer: Siv cov ntawv siv rau lub nplhaib khaws cia ntawm matrix sawb, kom zoo nkauj clamped ntawm lub plav.
Tso lub nplhaib rau cov hniav sib cais: ntxig taw hauv qhov chaw sib cais (buccal lossis lub cev nrov nrov tig mus rau sab mesial lossis sab distal. Yog tias ntsib Mesial, koj tuaj yeem tso koj cov ntiv tes rau kev txhawb nqa. Lub nplhaib pab cais cov hniav, npaj rau qhov kev tso kawm ntawm matrix sawb.
Tshem cov neeg saib xyuas thiab npaj kab noj hniav: nrog kev pab ntawm lub nplhaib, cais cov hniav thaum tshem cov khoom noj thiab npaj kab noj hniav. Xyuas kom meej tias txhua tus neeg caries yog muab tshem tawm kom muab qhov chaw tsim nyog rau cov khoom siv.
Kho cov duab ntawm matrix sawb: maj mam kho cov duab ntawm matrix satip kom haum tus hniav contour. Qhov no pab tswj cov duab kom yog ntawm cov khoom siv uas tau txig thaum kho.
Tso cov matrix sawb: Siv cov ntaub paj rwb lossis lwm cov pob zeb los tuav lub matrix sawb thiab tso nws nyob rau hauv lub tsev kab noj hniav. Ruaj huam lub matrix satip nrog ib tug neeg txhais lus ntawm wedge kom ntseeg tau tias muaj kev nruj haum nrog cov npoo sib dhos. Tus woofe kaw lub pob tawb margin sib cav kom tsis txhob overhangs.
Txhim kho cov matrix sawb: Tso tus taw ntawm lub nplhaib ntawm Matrix Sawb thiab tus neeg sib cais los kho cov lej matrix thiab txuas ntxiv mus sib cais. Xyuas kom cov matrix satip yog ruaj ntseg txuas rau tus hniav.
Tswj kev sib cuag cov ntsiab lus: maj mam muab thawb thiab rub lub matrix sawb kom ntseeg tau tias nws haum kom nruj nreem tiv thaiv tus hniav. Thaum kho cov kab noj hniav (mesio-occluso-distal kab noj), loj dua cov kab ke lossis ob lub nplhaib yuav siv los xyuas kom lub matrix sawb.
III. Kev ua haujlwm tom ntej
Sau cov khoom siv: nrog kev tiv thaiv ntawm matrix sawb, txhaj cov khoom lag luam rau hauv kab noj hniav. Xyuas kom cov khoom ntim tau tag nrho.
Tshem cov matrix sawb: Tom qab cov khoom lag luam yog kho tau, siv cov cuab yeej tsim nyog kom tshem cov matrix sawb thiab txhais lus npuav.
Polish thiab tshuaj xyuas: Siv cov khoom siv yaug thiab tshawb xyuas lub teeb polish rau polish thiab tshawb xyuas cov hniav rov qab, ua kom muaj kev txaus siab rov qab los.
Cov kev ceev faj
Kev ua lag luam tshaj lij: kev siv daim ntawv kho hniav kos yuav tsum tau ua los ntawm kws kho hniav kom ntseeg tau tias kev kho kom zoo dua qub thiab kev nyab xeeb kev nyab xeeb.
Qhov ncauj nyiam huv: Tom qab txoj kev kho kom rov kho dua los tiv thaiv qhov ncauj kom tiv thaiv cov neeg ua haujlwm theem nrab.
Kev xav txog kev noj haus kom tsis txhob haus cov khoom noj uas nyuaj dhau los tiv thaiv kev puas tsuaj rau txoj kev rov qab.
