Lub qhov ncauj Scan ua haujlwm li cas?

01. Keeb Kwm

Intraoral digital impression technology muaj keeb kwm ze li 40 xyoo. Thaum ntxov li 1980, Dr. Werner Mormann ntawm Switzerland thiab engineer Marco Brandestini ntawm Ltalis koom tes los tsim intraoral scanning technology.

Nyob rau hauv 1987, Sirona launched thawj tiam ntawm kev kho hniav kho hniav CAD/CAM system, CEREC kuv, thiab ntse tso tawm lub ntiaj teb no thawj coj mus muag intraoral 3D scanner.

iTero tau tsim thiab ua lag luam los ntawm Cadent (Israel) hauv xyoo 2007.

Trios system 3Shape (Denmark) tsim Trios system hauv 2010 thiab muab tso rau hauv kev ua lag luam hauv 2011.

Txog rau tam sim no, ntxiv rau yav dhau los tseem ceeb intraoral digital impression systems, kuj tseem muaj LavaC.OS system ntawm 3M lub tuam txhab, DWIO system ntawm Canada, peb lub tsev Langcheng system, thiab qee lub npe.

02. Txheej txheem txheej txheem

Muaj peb txoj hauv kev ua haujlwm tseem ceeb ntawm intraoral digital impression technology, uas yog confocal microscopy imaging technology, triangulation technology thiab active wavefront sampling technology. Lub iTero hom ntawm intraoral scanners siv confocal microscopy imaging technology. CEREC intraoral scanning system yog ib qho kev siv ntawm triangulation technology. Lub Lava COS (3M, USA) intraoral scanner yog ib qho uas twb muaj lawm uas siv lub tshuab ua haujlwm wavefront sampling technology

03. Muaj zog thiab kev txwv

Piv nrog rau cov txheej txheem kev xav ib txwm muaj, cov kev xav hauv nruab nrab ntawm lub cev kuj muaj qhov zoo hauv qab no:

Standard impression technology yuav tsum tau soj ntsuam impression ua thiab plaster qauv reproduction kom tau txais cov ntaub ntawv kho hniav thiab lub puab tsaig. Cov kauj ruam no yuav ua rau kev ua haujlwm yuam kev. Intraoral digital impression thev naus laus zis tuaj yeem ua kom yooj yim cov txheej txheem rau hauv ib kauj ruam. Qhov yuam kev ntawm qhov kev xav digital tsuas yog los ntawm kev ua yuam kev scanning, thiab kev tswj hwm ntawm qhov kev ua yuam kev tau txhim kho zoo heev;

Lub tswv yim intraoral digital tuaj yeem tau txais cov ntaub ntawv xim ntawm lub qhov ncauj mos thiab tawv nqaij thiab paub tseeb xim scanning;

Kev kho lub rooj zaum digital tuaj yeem ua tiav los ntawm intraoral digital scanning, txo tus neeg mob lub sijhawm tos. Txhim kho tus neeg mob siab;

Qee cov neeg mob uas muaj kev cuam tshuam loj heev yog qhov tsis txaus ntseeg rau cov ntaub ntawv xav tau siv rau hauv cov txheej txheem kev xav ib txwm muaj, thaum kev tshuaj ntsuam xyuas hauv lub cev tuaj yeem txhim kho kev nplij siab ntawm cov neeg mob;

Thaum kuaj intraoral, tus kws kho mob tuaj yeem soj ntsuam kev npaj kho hniav hauv lub qhov ncauj hauv lub sijhawm tiag tiag, uas yooj yim rau kev hloov kho raws sijhawm thiab hloov tau yooj yim.

Txawm li cas los xij, txwv los ntawm kev txhim kho thev naus laus zis tam sim no, intraoral digital impression technology kuj muaj qee yam kev txwv. Feem ntau nyob rau hauv cov nram qab no yam.

1. Rau lub puab tsaig edentulous uas tsis muaj qhov pom tseeb anatomical nta, nws yog qhov nyuaj kom tau txais cov kev xav digital thiab qhov tseeb scanning tsawg;

2. Tsis muaj nyob rau ib ntus; dynamic functional occlusion cov ntaub ntawv.

04. Daim ntawv thov kev kho mob

Tam sim no, intraoral digital impression technology tau siv dav hauv kev kho mob, suav nrog cov hauv qab no:

Chairside digital restoration: CEREC system yog ib qho kev kho lub rooj zaum digital. Tom qab cov ntaub ntawv kev npaj kho hniav nyob rau hauv tus neeg mob lub qhov ncauj sai sai tau los ntawm intraoral scanning, cov pa renovation tsim yog nqa tawm tam sim ntawd. Kev txiav thiab kev tsim khoom ntawm kev kho dua tshiab tuaj yeem ua tiav hauv 20-30min.

Digital Orthodontics: Lub I Tero intraoral scanner yog sib xws nrog Invisalign invisible aligner system, tshem tawm cov txheej txheem nyuaj ntawm kev tsim tawm thiab xa ntawv ntawm kev xav, paub txog kev siv tau zoo thiab yooj yim tsis pom kev tsim thiab txheej txheem tsim khoom.

Digital implant design: 3shape implant design software tuaj yeem koom ua ke nrog cov neeg mob CT tom qab xa cov ntaub ntawv hauv qhov ncauj, tsim cov phiaj xwm kev cog hniav digital, thiab tsim cov lus qhia kev phais digital.

05. Kev npaj ua ntej scanning

Ua ntej ua ib qho intraoral scan, cov khoom xav tau rau kev kuaj xyuas yuav tsum tau npaj. Ntxiv nrog rau cov cuab yeej sawv ntsug rau kev kuaj qhov ncauj, lub taub hau scanning thiab cov cuab yeej ntsuas ntsuas kuj tseem xav tau.

Ua ntej, nruab lub taub hau 3D calibration rau ntawm rab phom scan, thiab nyem rau ntawm lub scanner los teeb lub scanning 3D calibration scanner los ua 3D calibration. Intraoral scanners yog 3D calibrated ib hnub ib zaug.

Tom qab ntawd nruab cov hniav xim calibration lub taub hau thiab lub calibration thaiv ntawm lub scanner phom, kov lub scanner los teem lub scanning xim xim ntsuas xim calibration thiab ua raws li on-screen qhia kom ua cov xim calibration. Intraoral scanners yog calibrated txhua lub lim tiam

06. Cov txheej txheem luam theej duab

1. Nruab lub taub hau kom tsis muaj menyuam rau ntawm rab phom scan, coj mus rhaub Ntxiv Tus Neeg Mob ntawm lub scanner, thiab nkag mus rau cov ntaub ntawv tus neeg mob thiab kws kho mob. Nyem rau ntxiv ib rooj plaub, xaiv lub Hoobkas ua, cov hniav sib txuas thiab kho dua tshiab. Yog tias suav tias yog tus qauv tsim, koj tuaj yeem xaiv coj mus rhaub Xaiv Cov Qauv Kawm

2. Tus neeg mob txoj hauj lwm tuaj yeem xaiv tau ntawm 45 degree, lub intraoral scanner tau muab tso rau sab laug sab laug ntawm tus neeg mob, thiab tus kws kho mob sawv ntawm sab xis ntawm tus neeg mob los ua haujlwm scanning.

3. Cov qaub ncaug ntawm tus neeg mob cov hniav yuav cuam tshuam qhov tseeb thiab ceev ntawm kev tshuaj ntsuam xyuas, yog li so cov hniav nrog lub pob paj rwb qhuav ua ntej scan, thiab tom qab ntawd ziab cov hniav nrog rab phom cua.

4. Thaum kev kuaj xyuas, ua raws cov lus qhia kom scan occlusal nto ua ntej, tom qab ntawd lub lingual thiab buccal chaw, thiab thaum kawg, sau rau qhov khoob ntawm scan.

5. Thaum luam theej duab lub puab tsaig qis, lub taub hau scanning yog tig los, thiab thaum luam theej lub puab tsaig sab sauv, lub taub hau scan tuaj yeem raug tshem tawm thiab tig rov qab thiab ntsia rau ntawm rab phom scan rau scanning.

6. Tom qab txhua qhov scan, tus qauv scan yuav tsum tau muab txiav kom tshem tawm cov qauv mos mos uas tsis tsim nyog

7. Tom qab kuaj lub puab tsaig sab sauv thiab sab qis, pib tshawb xyuas thiab sau tus neeg mob ob sab occlusion kom paub tseeb tias tus neeg mob lub occlusion yog ruaj khov thiab zoo ib yam.

8. Tom qab occlusal scan tiav lawm, xyuas cov duab ntawm lub scanner

9. Tom qab kuaj xyuas, qhov kev txiav txim tuaj yeem xa mus rau cov khoom ua haujlwm sib raug
