Yuav ua li cas koom ua ke intraoral scanner cov ntaub ntawv nrog CAD / CAM thiab 3D tshuab luam ntawv?

Ⅰ. Cov ntaub ntawv yooj yim ntawm cov ntaub ntawv los ntawm intraoral scanners

Intraoral scanners muab cov qauv kho hniav digital uas feem ntau tau txais kev cawmdim raws li cov ntaub ntawv 3D. Qee hom qauv yog:
STL (Standard Tessellation Language)
Lub ntiaj teb no hom uas yog siv ntau tshaj
Siv daim duab peb sab mesh los qhia qhov chaw ntawm cov hniav thiab cov nqaij mos thiab tawv hauv lub qhov ncauj
Ua haujlwm nrog feem ntau CAD / CAM thiab 3D luam ntawv daim ntawv thov
PLY (Polygon File Format / Polygon Library)
Txhawb kev ntxhib los mos hauv cov xim thiab cov ncauj lus kom ntxaws ntxiv
Qee zaum siv hauv orthodontic simulations lossis kho kom zoo nkauj los qhia tawm cov xim ntawm cov pos hniav thiab kev ntxhib los mos ntawm cov hniav.
OBJ (Wavefront Object)
Pab nrog cov ntaub ntawv xim thiab cov ntaub ntawv
Qee lub CAD lossis rendering systems siv nws los qhia tawm qhov pom kev.
Cov ntsiab lus: STL yog cov ntaub ntawv dav dav thiab muaj zog tshaj plaws yog tias koj xav tsim kho kho dua lossis 3D luam tawm qauv.

Ⅱ. Yuav ua li cas txuas cov ntaub ntawv los ntawm intraoral scanner rau CAD / CAM

Cov kev kho hniav digital yog qhov tseem ceeb ntawm cov ntaub ntawv kev sib koom ua ke ntawm intraoral scanners nrog CAD / CAM systems. Feem ntau, cov txheej txheem mus zoo li no:

1. Tau txais cov ntaub ntawv thiab ua qee qhov kev ua tiav
Siv lub tshuab ntsuas intraoral kom tau txais 3D cov ntaub ntawv ntawm cov hniav thiab cov ntaub so ntswg hauv qhov ncauj
Siv lub tshuab scanner tsim -hauv software los ntxuav cov ntaub ntawv, sau cov khoob, thiab ua kom lub ntsej muag du tom qab luam.
Koj tuaj yeem ua cov kab ua ntej ntawm kev sib txuas tom qab siv los ua cov lus qhia thaum tsim hauv CAD.

2. Exporting cov ntaub ntawv
Export 3D cov ntaub ntawv uas tau ua tiav raws li STL, PLY, lossis OBJ cov ntaub ntawv
Txheeb xyuas cov ntaub ntawv kom pom tias nws ua tiav thiab yog tias muaj cov qhov lossis cov duab peb sab txawv.
Qhov loj thiab kev daws teeb meem ntawm cov ntaub ntawv yuav txiav txim siab seb CAD / CAM machining ua haujlwm zoo npaum li cas tom qab.

3. Tsim nyob rau hauv CAD
Koj tuaj yeem xa cov ntaub ntawv STL rau hauv CAD cov kev pab cuam xws li Exocad, 3Shape Dental System, thiab CEREC CAD.
Ua kom rov kho dua nyob ntawm txoj kev npaj kho mob:
Ib tug crown los yog multi crown choj
Lub cev embedded, veneer
Muab tso rau hauv lub sab sauv qauv
Kev kho hniav ib ntus lossis kev ua haujlwm
Hauv CAD tsim, koj tuaj yeem ua cov hauv qab no:
Hloov cov kab npoo npoo
Hloov hauv occlusion
Tsim kom zoo nkauj (morphology thiab ntxoov ntxoo)

4. CAM machining

Tom qab koj ua tiav CAD tsim, nqa cov qauv lossis cov ntaub ntawv kho dua tshiab rau hauv CAM program.
CAM software tsim cov ntaub ntawv rau txoj kev milling los yog hlais rau 3D luam ntawv.
Tshawb nrhiav seb cov khoom siv thiab cov txheej txheem siv li cas:
Aluminium zirconia, tag nrho cov ceramic, hlau porcelain PMMA, cob, thiab lwm yam.
Xaiv qhov raug luam ntawv, txheej tuab, thiab cov cuab yeej txiav.

Ⅲ. Yuav ua li cas txuas cov ntaub ntawv los ntawm intraoral scanner mus rau 3D tshuab luam ntawv

Cov ntaub ntawv digital kuj yog qhov tseem ceeb tshaj plaws ntawm 3D luam ntawv.

1. Importing thiab dicing cov ntaub ntawv
Load STL cov ntaub ntawv rau hauv 3D luam ntawv program (Slicer)
Teem lub precision ntawm kev luam ntawv (feem ntau 25 txog 100 microns)
Xaiv hom khoom siv luam ntawv:
Photosensitive resin rau cov hniav hniav, txuas hniav, thiab cov ntawv qhia
Kev kho hniav ib ntus resin
Clear resin (cov lus qhia kho hniav los yog cov cuab yeej orthodontic)

2. Tsim kev txhawb nqa
Software ua kev txhawb nqa ntawm nws tus kheej lossis los ntawm tes.
Xyuas kom cov txheej txheem luam ntawv ruaj khov kom tsis txhob ua tsis tiav lossis deformation.

3. Kev luam ntawv thiab ua tiav
Tso tawm rau lub tshuab luam ntawv los ua cov khoom
Tom qab luam ntawv tiav:
Ntxuav cov seem resin
Kev kho mob siv UV
Polishing thiab sib tsoo

Yog tias nws yog kev kho dua tshiab, nws tuaj yeem siv tam sim ntawd hauv tsev kho mob lossis muab rau cov kws tshaj lij rau kev ua haujlwm ntxiv.

Ⅳ. Tej yam yuav tsum nco ntsoov thaum docking

1. Compatibility ntawm cov ntaub ntawv
Xyuas kom tseeb tias lub tshuab nqus tsev intraoral tuaj yeem nyeem STL, PLY, thiab OBJ cov ntaub ntawv hauv txhua hom ntawv.
Nco ntsoov tias CAD/CAM thiab 3D luam ntawv software tuaj yeem nyeem hom ntawv no ib txwm muaj.
Txhawm rau kom cov chaw tsim khoom kaw - lub voj kaw tsis ua rau nws tsis tuaj yeem nqa cov ntaub ntawv mus rau lwm yam khoom siv

2. Qhov tseeb ntawm cov ntaub ntawv
Cov ntaub ntawv STL yuav tsum muaj tseeb txaus rau kev kho uas yuav tsum tau ua nyob rau theem micrometer.
Poob lossis suab nrov thaum luam theej duab yuav ua rau cov npoo ntawm kev kho dua tshiab tsis haum.
Qhov sib npaug zoo ntawm kev ceev thiab qhov tseeb tuaj yeem pom nrog siab - scanning precision thiab cov ntaub ntawv zoo compression piv.

3. Lub software ecosystem
Yuav ua li cas zoo CAD software thiab scanners ua haujlwm ua ke
Puas muaj kev lees paub ntawm cov npoo thiab cov cim tom, nrog rau lub peev xwm los cog Scanbodies?
Puas yog slicing software rau 3D luam ntawv ua haujlwm nrog cov ntaub ntawv koj siv hauv koj lub tsev kho mob?

4. Cov ntaub ntawv ntawm kev sib raug zoo tom
Thaum docking CAD, tom cov ntaub ntawv yog qhov tseem ceeb heev.
Xyuas kom tseeb tias lub scanner sau li cas lub puab tsaig sab sauv thiab sab qis muaj feem xyuam rau ib leeg.
Xyuas kom tseeb tias cov ntawv luam tawm rov qab tsis raug tom thiab yuav tsum tau kho dua.

5. Khaws thiab tiv thaiv cov ntaub ntawv
Yuav tsum muaj ib txoj hauv kev rau thaub qab cov ntaub ntawv.
Tsis txhob cia poob cov ntaub ntawv digital nkag mus rau hauv txoj kev kho cov neeg mob.
Xav txog kev siv huab cia lossis khaws cov ntaub ntawv ntawm lub server hauv zos.

Ⅴ. Tej teeb meem thiab kev daws teeb meem
