Dab tsi yog qhov txawv ntawm kev kho hniav hlais tshuab, kho hniav panorama tshuab thiab kho hniav CBCT?
Thaum cov hniav muaj cov kab mob sib sib zog nqus, nws tsis tuaj yeem paub qhov tob ntawm cov kab noj hniav, qhov deb ntawm cov hlab ntsha ntawm cov hniav, thiab seb puas muaj cov hauv paus o los ntawm kev kuaj qhov ncauj ib leeg. Yog li ntawd, thaum cov hniav muaj teeb meem, cov kws kho mob yuav xav kom cov neeg mob mus kuaj zaj duab xis, thiab lub qhov ncauj zaj duab xis tshuab feem ntau suav nrog kev kho hniav tshuab, hniav panorama tshuab thiab hniav CBCT. Dab tsi yog qhov txawv ntawm peb? Yuav xaiv li cas?
1. Cov tshuab hniav
Lub tshuab feem ntau muaj cov khoom siv hluav taws xob X-ray generating device thiab nws cov khoom txhawb nqa, thiab siv nrog rau hauv - lub qhov ncauj daim duab receiver. Nws yog siv rau X-ray duab ntawm cov hniav kom tau txais cov duab rau kev kuaj mob. Nws yog qhov yooj yim heev, thiab feem ntau tuaj yeem nqa ob- cov duab qhov ntev ntawm 1 txog 4 hniav tib lub sijhawm, tab sis cov qauv sib tshooj yog qhov hnyav thiab qhov ntau me me.
2. Kev kho hniav panorama
Lub tshuab kho hniav panoramic feem ntau muaj xws li X-ray generator, ib qho aperture thiab tawm - ntawm - lub qhov ncauj daim duab receiver. Kev txheeb ze ntawm X- cov khoom siv hluav taws xob tsim hluav taws xob thiab cov duab txais sab nraum lub qhov ncauj. Siv rau nkhaus nto tomography ntawm qhov ncauj thiab maxillofacial cheeb tsam (xws li mandible, maxillary sinus, temporomandibular sib koom thiab cov hniav), nws yuav muaj cranial lateral imaging function rau kev kuaj mob, thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv lub qhov ncauj kev kuaj thiab kev kho mob.
Txawm li cas los xij, vim tias nws yog ob-dimensional, nws yog tsis yooj yim sua kom soj ntsuam peb -dimensional qauv, yog li occlusion thiab gaping ntawm txawv qauv tsis tuaj yeem zam tag nrho. Qhov luaj li cas ntawm qhov kev taw qhia lingual tsis tuaj yeem tshwm sim, lub hauv paus kwj dej raug tshem tawm, thiab cov kev taw qhia ntawm lub hauv paus kwj dej tsis tuaj yeem raug txiav txim, thiab tej zaum yuav ua rau kev kuaj mob yuam kev.
3. Kev Kho Hniav CBCT
Kev Kho Hniav CBCT, tseem hu ua lub qhov ncauj thiab maxillofacial cone beam CT, digital volumetric tomography, yog siv los tso saib cov ntaub so ntswg thiab cov ntaub so ntswg ib txwm los ntawm peb- qhov kev xav, uas yog sagittal, coronal thiab axial txoj haujlwm, kom tsis txhob muaj qhov tshwm sim. qhov tsis xws luag ntawm ob-dimensional plain films. Xws li cov ntaub so ntswg thiab cov duab hauv lub cev sib tshooj, qhov projection lub kaum sab xis hloov pauv los ntawm cov duab distortion, deformation thiab lwm yam, zoo heev txhim kho lub peev xwm kuaj mob.
Kev Kho Hniav CBCT tuaj yeem ua tiav qhov ncauj scan ntawm cov neeg mob hauv ntau tshaj kaum vib nas this, thiab tom qab ntawd ua kom muaj siab -THHREE-DIMENSIONAL duab, uas daws tau tag nrho cov teeb meem ntawm daim duab sib tshooj thiab cuam tshuam ntawm qhov ncauj ib txwm muaj X{{2 }}cov khoom siv hluav taws xob xws li kho hniav X-ray tshuab thiab tshuab kho hniav panoramic. Nws tuaj yeem soj ntsuam cov pob txha ceev ntawm cov pos hniav, qhov siab thiab dav ntawm cov pob txha alveolar hauv 360 degree, uas tuaj yeem tsis tsuas yog rov tsim kho cov qauv ntawm tag nrho cov cheeb tsam craniofacial, ntsuas cov pob txha qauv ntawm cheeb tsam maxillofacial, tab sis kuj rov tsim kho cov ntsiab lus zoo anatomical. .
