Intraoral Scanner: Illustrated Scanning Trajectory & Cov txheej txheem ua haujlwm
Ntau hom tshuaj intraoral scanner muaj nyob rau hauv kev ua lag luam tam sim no, tab sis lawv cov kev ua haujlwm ua haujlwm zoo sib xws.
Tsab ntawv xov xwm no qhia txog cov txheej txheem kev khiav hauj lwm rau intraoral scanning trajectories. Nws muab cov lus qhia ua haujlwm tau zoo rau cov kws kho hniav uas twb tau siv lub tshuab nqus pa hauv lub cev, thiab muaj kev nkag siab zoo rau cov kws kho mob xav txog kev siv cov cuab yeej digital no.
Pre-scan Preparation Notes
Ua ntej pib scanning, ua raws li cov hauv qab no ua ntej kev kuaj xyuas:
Txheeb xyuas qhov xwm txheej scanner txuas. Kev sib txuas cov txheej txheem sib txawv ntawm ntau hom intraoral scanner hom.
Tshem lub hau tiv thaiv thiab ua kom tsis muaj menyuam kom tsis muaj menyuam. Lus Cim: Cov kaus mom tiv thaiv tsis tau nruab nrog cov tsom iav tsom iav.
Ua kom sov lub scanning tswv yim. Lub sijhawm ua kom sov yog li ntawm 20 vib nas this mus rau 2 feeb, raws li qhov ntsuas kub ntawm chav tsev.
Cov txiaj ntsig ntawm scanning lub taub hau ua ntej ua kom sov: nws txo cov neeg mob tsis xis nyob thaum lub taub hau muab tso rau hauv lub qhov ncauj kab noj hniav, thiab tiv thaiv pos huab los ntawm intraoral exhaled ua pa, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm scanning thiab cov ntaub ntawv raug.
Kev Tshawb Fawb Txoj Kev 1: Ntau ntu S-Shaped Trajectory Scanning
Scanning sequence: Occlusal nto → Labial / Buccal nto (los yog Lingual nto) → Lingual nto (los yog Labial / Buccal nto). Nruab nrab qaij thiab tig lub scanner sojntsuam thoob plaws qhov tau txais.
Raws li tau piav qhia hauv daim duab, pib los ntawm qhov chaw occlusal ntawm ib sab ntawm cov hniav arch. Ua raws li txoj kev S-shaped: occlusal nto → lingual nto → labial-buccal nto. Tig lub scanning ntsis me ntsis kom ntes txhua tus hniav, thiab ua kom tiav tag nrho-arch scanning zuj zus.
Ua lub hom phiaj ntxiv kev tshuaj ntsuam xyuas tom qab ntawd: qhov chaw ntawm qhov chaw nruab nrab ntawm cov molar feem ntau, qhov sib txuas sib txuas sib txuas thoob plaws lub qhov rooj hniav, cov ntaub so ntswg hauv zos, thiab cov cheeb tsam uas tau teeb tsa los ntawm software scanner.
Pasing yog tso cai thaum scanning. Thaum rov pib qhov kev yuav khoom, rov qab mus rau lossis mus ze rau thaj chaw uas tau txheeb xyuas yav dhau los ze ntawm qhov chaw nres. Tsis txhob dhia dhia mus rau qhov chaw nyob deb.
Txoj Kev Scanning 2: Segmented Sequential Scanning
Kev Ua Haujlwm: Tshawb xyuas qhov chaw occlusal ua ntej, tom qab ntawd taug kev mus rau qhov chaw hais lus, thiab thaum kawg ntes cov chaw labial-buccal. Txoj kev no muaj peb qhov sib txawv scanning passes:
Occlusal pass: Pib ntawm qhov kawg ntawm cov molars tom qab. Tshawb xyuas qhov chaw occlusal, ua tus Z-shaped sway hla incisors ntawm cov hniav anterior (canine-to-canine), txuas ntxiv mus rau sab nraud occlusal koov, thiab xaus ntawm cov molar distal.
Lingual-surface pass: Muab cov lus qhia scanning nyob ib ncig ntawm lub ces kaum distal molar kom nkag mus rau sab lingual. Tshawb xyuas cov molars tom qab, cov hniav anterior, thiab cov molars ntawm sab contralateral.
Labial-buccal-surface pass: Tig lub taub los ntawm lub lingual distal molar mus rau qhov chaw buccal. Ntws cov molars tom qab molars, anterior labial nto, thiab cov molars ntawm sab nraud.
Ua kev soj ntsuam ntxiv rau cov molars tom qab, thaj chaw gingival, thiab software-highlighted qhov chaw.
Kev tshuaj ntsuam xyuas yuav raug nres. Thaum rov pib dua, rov qab los ze rau qhov qub-scanned ncua txoj haujlwm. Tsis txhob ua dhia scanning.
Bite Registration Scanning Protocol
Tau txais 3-4 qhov zoo sib cais tom cov ntsiab lus ntawm kev tshuaj xyuas qhov chaw.
Cov kev siv tom-scanning workflow txawv ntawm cov qauv scanner; ib txwm ua raws li cov qauv qhia tshwj xeeb. Multi-point bite sau npe muab kev yooj yim dua, kev sib raug zoo dua thiab muaj txiaj ntsig zoo dua rau kev sib tw tsis siv neeg tom.
Clinical tips for tom scanning:
Qhia cov neeg mob kom tom ib txwm tsis muaj clenching ntau dhau, thiab tswj kom ruaj khov occlusion thoob plaws kev ntes.
Ntxig lub scanning sab xis rau hauv lub qhov ncauj kab noj hniav. Tshem tawm cov ntaub so ntswg nrog rau sab nraud ntawm qhov kev sojntsuam, kho lub lens mus rau tom cov neeg sib cuag, tom qab ntawd nias lub pob khawm kom pib scanning.
Txheeb xyuas qhov tseeb occlusal thaum scanning tiav.
Cov txheej txheem scanning tseem ceeb & Cov kev coj ua zoo tshaj plaws
Thaum hloov ntawm qhov chaw occlusal mus rau qhov chaw ntawm lub lingual los yog labial-buccal, qaij thiab tig lub scanning lub taub hau raws tus nkhaus nkhaus. Tsis txhob tig lub kaum sab xis ntse, uas ua rau cov ntawv sau npe tsis sib haum thiab cov ntaub ntawv scan tsis raug.
Ua ntej tshaj qhov kev tshuaj ntsuam xyuas ntxiv rau cov cheeb tsam uas muaj qhov tseem ceeb tshaj plaws:
Distal nto ntawm qhov kawg molars
Interproximal qhov chaw
Gingival thaj chaw nrog cov ntaub so ntswg qhov siab tsawg dua 3-4 mm
Intraoral scanners reconstruct 3D qauv los ntawm stacking sequential intraoral dluab. Txhawm rau sib npaug scanning precision thiab workflow efficiency, ntes tsuas yog cov duab txaus rau kev npaj cov hniav morphology, ntshiab interproximal hu, thiab ua tiav kev siv lub cev ntawm cov hniav uas nyob ib sab thiab tawm tsam; cov thav duab tsis tsim nyog yuav tsum tau txo qis.
Feem ntau intraoral scanner manufacturers pom zoo kom txwv tag nrho-arch scan thav duab rau kwv yees li 1000 dluab.
Lus Cim: Kev ua tiav tom qab yuav tsum tshem tawm cov khoom siv tsis tu ncua xws li qhov tsis sib xws ntawm qhov nruab nrab thiab cov gingival margins, txwv tsis pub tus qauv precision yuav raug cuam tshuam. Muaj ntau cov khoom siv hauv lub cev scanning txhawb nqa qhov tsis siv neeg lub qhov ntim thiab qhov kawg qauv optimization ua haujlwm.
Tsim qhov kawg 3D Digital Model
Cov kws kho hniav tuaj yeem xa cov ntaub ntawv scan hauv STL cov ntaub ntawv. Cov ntaub ntawv tuaj yeem muab faib los ntawm huab platforms lossis email nrog cov kws tshaj lij hauv chav kuaj. Kev sib tham sib tham hauv online digital cov hniav tuaj yeem ua tiav kom tiav cov phiaj xwm kho hniav.
