Manufacturing Workflow of Traditional Dental Full Crowns
Dental Impression AcquisitionTus kws kho hniav sau cov hniav zoo nkauj los ntawm kev siv cov kev xav hauv qhov ncauj nrog cov ntaub ntawv zoo siab.
Gypsum Model FabricationQhov kev xav tiav yog xa mus rau chav kuaj hniav. Cov kws kho hniav kho hniav ncuav gypsum thiab tsim lub cev plaster qauv ntawm tus neeg mob cov hniav.
Kev npaj ciabCov kws kho mob kos duab thiab tsim cov khoom siv quav ciab ua tiav ntawm cov qauv plaster.
Peev Casting thiab High-temperature DewaxingCov qauv siv quav ciab yog embedded hauv cov khoom siv peev. Cov cua kub kub kub kub hnyiab tawm ntawm cov quav ciab thiab tawm ntawm cov kab noj hniav hollow.
Khoom siv CastingMolten hlau los yog ceramic raw khoom yog poured rau hauv lub hollow kab noj hniav. Lub crown blank yuav zoo li tom qab txias thiab solidification.
Kev kho kom tiavCov yas yas yog stripped los ntawm cov khoom siv peev. Cov neeg ua haujlwm hauv chaw ua haujlwm txiav, sib tsoo, polishing thiab zoo haum yog li qhov kev kho kom rov zoo zoo haum rau tus neeg mob cov hniav npaj.
Txheej Txheem Flow rau Digitally-fabricated Full Crowns
Peb-dimensional Digital ScanningCov kws kho mob ntes cov hniav 3D cov ntaub ntawv ncaj qha los ntawm lub qhov ncauj scanner. Hybrid scanning combining intra-oral scanning thiab plaster-model scanning kuj muaj rau complex qhov ncauj.
Computer-aided Crown DesignScan-acquired digital files yog imported rau hauv CAD/CAM software. Cov kws kho hniav ua tiav kev tsim qauv virtual thiab tsim kho lub ntsej muag tag nrho ntawm lub computer.
CNC Tsis Siv Neeg MillingUa tiav cov ntaub ntawv tsim tau raug xa mus rau tus lej-tswj milling tshuab. Cov cuab yeej txiav thiab ua cov khoom nyoos ceramic lossis hlau thaiv rau hauv lub cev lub cev tau txais.
Post-processing thiab Occlusion AdjustmentMilled crowns mus los ntawm kev sib tsoo, nto polishing thiab cov ncauj lus kom ntxaws occlusal hloov kho kom ua tau zoo, meej intra-oral adaptation.
